...................................................................................................................79 vi About the EMC Disk Library Introduction to the EMC® Disk Library The EMC Disk Library combines hardware controllers with a storage-system disk into an appliance that makes virtual tape libraries available on a Fibre Channel storage area network (SAN). These virtual tape libraries are direct, plug-and-play replacements for physical libraries. The basic logical components of a EMC Disk Library system are: • • • • • Virtual libraries Virtual tape drives Virtual volumes SAN clients Physical libraries (optional) Hardware and software components The EMC DL210 Disk Library rack series (or field install kit) includes the following base hardware components: One Intel-based EMC Disk Library server, which contains the following: One flexible-use port that you can interchange for either host connections, expansion storage connection, or a physical library configuration: o One auto-negotiating target port 1, 3, and 5 for connection to the Fibre Channel (FC) storage area network (FC SAN) , or Direct Connection (FC-AL) with the backup systems. For information on supported switches and backup systems, refer to the EMC Support Matrix. o One auto-negotiating FC 4 Gb/s or initiator port 5 for physical tape libraries or physical tape drives. EMC supports a maximum of four physical tape libraries or physical tape drives per Disk Library server. Six available direct connections to the enclosed EMC AX-series storage system. One auto-negotiating 10/100/1000 Mbps Ethernet NIC to increase performance with LAN-based communications. Note: The only time that the network speed might be important is if you are planning to use remote copy (remote copy over IP). You can use remote copy only if you have a GigE or better network connection. Depending on the DL210 system ordered and configured, up to six AX-series Storage Enclosures can be added to the base appliance hardware. Adding Storage Enclosures (Shelves) increases the total aggregate capacity in the DL210 appliance. CAUTION The EMC storage system is preconfigured with a specific structure. Any changes to the setup or cabling will result in data loss. The EMC DL4x00 Disk Library rack series includes the following base hardware components: One or more Intel-based EMC Disk Library servers that contains the following: Eight flexible-use ports that you can interchange for either host connections or a physical library configuration: o Four auto-negotiating target ports 1, 3, 7 and 11 for connection to the Fibre Channel (FC) storage area network (FC SAN) with the backup systems. EMC does not support a direct connection to backup systems. For information on supported switches, refer to the EMC Support Matrix. 1 EDL printed help o Four auto-negotiating FC 4 Gb/s or initiator ports 4, 5, 8 and 9 for physical tape libraries or physical tape drives. EMC supports a maximum of four physical tape libraries or physical tape drives per Disk Library server. Note: The DL4200 and DL4400 front-end, flexible-use ports support FC-loop mode (FC-AL) only and require a switch that support FC-loop mode. FC-loop mode allows a single port to take on multiple WWPNs to support the active-active with active engine failover feature, if it is enabled. The backup hosts will still use FC-fabric mode (FC-SW) connections to the switch. The FC-AL to FC-SW interconnections are handled by the switch. FC-AL connections are required whether or not active engine failover is enabled. For information about the DL4200 and DL4400 configurations, refer to EMC Disk Library configuration. For information about the active-active with active engine failover, refer to Using active-active with active engine failover. • • Four direct connections to the enclosed EMC CX3 series storage system. Four auto-negotiating 10/100/1000 Mbps Ethernet NIC to increase performance with LAN-based communications. EMC Disk Library functions that use the network will see an advantage when additional network ports are used. Note: The only time that the network speed might be important is if you are planning to use remote copy (remote copy over IP). You can use remote copy only if you have a GigE or better network connection. Depending on the model, one or more CX3 series storage systems with one or more shelves of SATA (serial advanced technology attachment) drives, you can add shelves of 15 SATA disk drives to the base hardware. Adding shelves increases the total aggregate capacity of the CX3 series storage system as well as the capacity in the DL4x00 storage systems. CAUTION: The EMC storage system is pre configured with a specific structure. Any changes to the setup or cabling will result in data loss. The EMC DL6x00 Disk Library rack includes the following base hardware components: Two to Four Intel-based EMC Disk Library servers each of which contains the following: Four auto-negotiating FC target ports 1, 3, 7 and 11 for connection to the Fibre Channel (FC) storage area network (FC SAN) with the backup systems. • Four auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 4, 5, 8 and 9 (in the DL6300) and two auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 4 and 8 (in the DL6100) for physical tape libraries or physical tape drives. • • • Four auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 0, 2, 6, and 10 (in the DL6300) and six auto-negotiating FC 4-Gb/s or 4-Gb/s initiator ports 0, 2, 5, 6, 9, and 10 (in the DL6100) for connection to the storage element. Four auto-negotiating 10/100/1000 Mbps Ethernet NICs per engine to increase performance with LAN-based communications. Note: The DL6100 and DL6300 front-end, flexible-use ports support FC-loop mode (FC-AL) only and require a switch that support FC-loop mode. FC-loop mode allows a single port to take on multiple WWPNs to support the active-active with active engine failover feature, if it is enabled. The backup hosts will still use FC-fabric mode (FC-SW) connections to the switch. The FC-AL to FC-SW interconnections are handled by the switch. FC-AL connections are required whether or not active engine failover is enabled. 2 About the EMC Disk Library For information about the DL6100 and DL6300 configurations, refer to EMC Disk Library configuration. For information about the active-active with active engine failover, refer to Using active-active with active engine failover. EMC Disk Library functions that use the network will see an advantage when additional network ports are used. Note: The only time that the network speed might be important is if you are planning to use remote copy (remote copy over IP). You can use remote copy only if you have a GigE or better network connection. CAUTION The EMC DMX storage system is preconfigured with a specific structure. Any changes to the setup or cabling will result in data loss. The EMC Disk Library Console program. You will install and run the Console program on a customerprovided management workstation with Windows 2000 SP2 or higher, Windows XP or Windows Server 2003 installed. The management station must have a LAN port that is connected to the same network to which the EMC Disk Library is connected. The network connection can be 10BaseT, 100BaseT, or GigE. For information on device and backup software package, refer to the EMC Disk Library Release Notes. EMC Disk Library configuration The EMC Disk Library is available in six configurations, which include the DL210, DL4100 (1 x 1), DL4200 (2 x 1) and, DL4400 (2 x 2), DL6100 (2 x 1), and DL6300 (4 x 1). Note: In the DL4200, DL4400, DL6100, and DL6300 configurations, virtual tape libraries created on one Disk Library host do not have access to tapes on the other Disk Library host. All DL4200 configurations come with a minimum of one DAE3P-SATA 15-disk shelf. You can add more shelves to the EMC storage system to increase the storage capacity. All DL210 configurations come with a minimum of one AX150SC storage system. You can add more AX150SC storage systems to increase the storage capacity. The DL6100 model can be configured from 4 to 6 Storage Cabinets. The DL6300 model can be configured from 6 to 10 Storage Cabinets. Adding cabinets increases the total aggregate capacity of the DMX series storage system as well as the capacity in the DL6x00 storage systems. The older configurations, DL310, DL710, DL720, and DL740, are supported with the upgrade to the EMC Disk Library Console. EMC recommends that you keep a configuration sheet listing the items below. You can use this configuration sheet in case you need to re-configure the EMC Disk Library manually. EMC Disk Library Configuration Sheet 3 EDL printed help About the EMC Disk Library Console You administer the EMC Disk Library through the EMC Disk Library Console, which you must install on a system in your environment. The Console is a user interface (UI) tool that you use to configure the EMC Disk Library, add and configure clients, set properties, and manage the import/export of tapes. You can use the Console to manage more than one EMC Disk Library. Note: The Console icon for v3.x on the management workstation will display as EMC Disk Library Console 3.x. You can install v2.x and v3.x on the same management workstation Related Topics: To install and set up the EMC Disk Library Console, see Installing and Setting Up the Disk Library Console. For information on the Console’s main menu, tree, and main window options, see Trees, Menu Options, and the Main Window. 4 Installing and Setting Up the Disk Library Console Installing the EMC Disk Library Console program The EMC Disk Library Console is a Windows-based application. The management system on which you will install and run the EMC Disk Library Console program must have a LAN port that is connected to the same network to which the EMC Disk Library is connected. This enables communication between the management station and the EMC Disk Library server. The Disk Library Console uses TCP port 11576 to communicate with the Disk Library server, and UDP port 11577 for remote copy. If you plan to have the Disk Library Console and the Disk Library server communicate through a firewall, you must open up both these ports. For information on operating systems supported by the Disk Library Console, refer to the EMC Disk Library Release Notes. Note: Only a power user or an administrator can install the Console. To install the EMC Disk Library Console 1. Insert the EMC Disk Library Management Console Software and Documentation CD into the CDROM. The CD automatically launches a menu window. Note: If the CD does not automatically launch a menu window, navigate to the CD-ROM drive in an Explorer window and select the setup.exe file. 2. 3. Select Software. The Software window displays. Follow the instructions on the Software window to install the Console. Required procedures for the EMC Disk Library Console setup The following procedures are required to set up the Disk Library Console: • Setting up and configuring the Disk Library • Initializing the Disk Library DL210 servers • Adding a Disk Library server to the Console • Logging in to the Disk Library server • Viewing and managing the event log • Changing the default password • Using the Configuration wizard • Saving and restoring • Mirroring the virtual tape library database 5 EDL printed help Setting up and configuring the Disk Library An EMC service provider sets up and configures the Disk Library. You can configure additional virtual tape libraries using the Disk Library Console. Default SAN client The Everyone_FC SAN client is the default SAN client. All non-configured host systems use the Everyone_FC SAN client. Once you have configured a host system as a SAN client, that system no longer uses the Everyone_FC SAN client object. If you assign one or more virtual tape devices (libraries or drives) to the Everyone_FC SAN client, then all non-configured host systems on the FC SAN with the Disk Library server will be able to use these resources (provided that FC switch zoning allows these host systems to see the Disk Library server). You can assign the default library to the Everyone_FC client. This is useful when you initially configure the Disk Library server because it allows the pre-configured virtual tape library to be available to all of the FC systems permitted by your FC zoning. Initializing the Disk Library DL210 servers Before you add a Disk Library DL210 to the Disk Library Console, you must initialize and set up the IP address on the Disk Library DL210 server. Follow the steps below to initialize and set up the IP address using the initialization wizard: 1. 3. Go to Tools and select Initialize Disk Library servers. 2. The EDL Initialization Wizard will appear. Select Begin. The available EDLs window will appear with the serial numbers of the available DL210s on your network. Select the serial number of the DL210 that you want to configure and select Configure. The IP Configuration window will appear. Enter the IP address and net mask for the DL210 and click Next. Note: Use a distinct IP address to initialize the Disk Library DL210 to avoid an IP address conflict. 4. 5. 6. The Gateway window will appear. You can enter an optional gateway and click Next. A Finish window will appear with the configuration summary. Verify the details that appear in the window. Click Finish to complete the configuration. Once you initialize the DL210 system, it will disappear from the Available EDLs window. To see the DL210 system in the Console, follow the steps in Adding a Disk Library server to the Console. Adding a Disk Library server to the Console The Disk Library Console communicates with each Disk Library via the Disk Library server. To add your Disk Library server to the Disk Library Console: 1. 2. Open the Disk Library Console program. In the EMC Disk Library Console window, right-click the Disk Libraries and select Discover. Note: Instead of performing a Discover, you can right-click your Disk Library server icon, and select Add. Enter your Disk Library server’s IP address or IP name in the Disk Library Server text box. Enter dladmin in the User Name text box and password in the Password text box. For default username and password information, refer to Logging in to the Disk Library server. Click OK and skip to step 4. 6 Installing and Setting Up the Disk Library Console 3. In the Discover Disk Library Server dialog box, enter your subnet in the Subnet filter box. The Subnet filter will show the subnet information for the system on which you are running the Console program. The Disk Library server ships from the factory with the address 192.168.1.2. Note: On a DL4200, DL4400, DL720, and DL740 server A ships with the default IP address 192.168.1.2, and server B ships with the default IP address 192.168.1.3. On a DL6100 and DL6300, server A ships with the default IP address 192.168.1.2, server B ships with the default IP address 192.168.1.3, server C ships with the default IP address 192.168.1.4, and server D ships with the default IP address 192.168.1.5 Note: model DL6100 only comes with server A and B. If you need to change the address, you can temporarily add an address in the 192.168.1 subnet to the system running the Console program, for example, 192.168.1.100. This allows the system to find the Disk Library server while it uses the default IP address. To change the IP address, see Accessing the Disk Library server through the Console. Click OK. 4. The Console program locates your Disk Library and adds an entry for the Disk Library under the Disk Library servers icon. Note: When you start the Disk Library server after an installation, it will not assign the address 192.168.1.2 to its network interface card (NIC) if another system on the network is using the same IP address. To overcome this, you can either shut down the system or change its IP address. If the system does not have an IP address on the same sub-net as the Disk Library Appliance you would like to manage. Follow the procedures given in the link below, to add an IP address to the system on which you are running the Disk Library Console and access the Disk Library server through the Console. Accessing the Disk Library server through the Console After the Disk Library server is available on the network, follow the procedures in Setting up the network configuration in the Disk Library Console to set the network configuration in the Disk Library Console. Deleting a Disk Library server from the Console To delete your Disk Library server from the Disk Library Console, do the following: 1. 2. Run the Disk Library Console program. In the EMC Disk Library Console window, right-click the Disk Library server that you want to delete, and select Delete. The Console program removes this Disk Library server from the display. The Disk Library server will continue to function, and you can manage it from another Console program in your environment. Logging in to the Disk Library server 7 EDL printed help To log in to a Disk Library server: 1. 2. Right-click your Disk Library server icon, and select Connect. In the Disk Library User Login dialog box, you can log in with either of the two user names and passwords. • Enter dladmin for Username and password for Password. Click OK. The Console Login dialog box opens, and displays server status messages, beginning with the message, Connecting to Disk Library Server. Logging in with this username and password provides you with privileges to access all the features of the Console. • Enter dlmon for Username and monitor for Password. This login allows you to only monitor and create reports, but not edit them. Note: On a DL4200, DL4400, DL720, DL740, DL6100, and DL6300 the server you log in to will connect first, and then search the subsequent server(s) to connect. Viewing and managing the event log Once you have logged in to a server, you can view, filter, export, purge, or print the event log for that server as described in this section. The event log reports messages such as job completions, tape creations, user management, and hardware notifications. • • • • Viewing the event log Exporting the event log Purging the event log Printing the event log Changing the default password Once you have configured the Disk Library Console, you should change the default configuration password as follows: 1. 2. 3. Right-click the Disk Library server icon and select Change Password. Enter the default password, a new password, confirm the new password. Click OK. Note: For information on the default username and password, refer to Logging in to the Disk Library server. Using the Configuration wizard Creating a virtual tape library and virtual tapes, and associating these with physical libraries and SAN clients, requires a number of steps. To simplify the standard configuration process, the Disk Library Console provides a configuration wizard. To open the Configuration wizard: 1. 8 From the Console, select your Disk Library and right-click Virtual Tape Library System and select the Configuration wizard. Alternatively, you can click the Configure button that appears in the main window of the Disk Library Console. The wizard lists an overview of the standard configuration steps. Installing and Setting Up the Disk Library Console The following three selections are available: Next – To execute the configuration step indicated by the yellow triangle. Skip – To bypass the configuration step indicated by the yellow triangle. Cancel – To exit the Configuration wizard. 2. Create virtual libraries – see Creating virtual tape libraries. 3. 4. 5. Add SAN clients and assign virtual libraries to clients– see Adding a SAN client. Prepare physical tape library/drive devices – see Connecting and managing tape devices. Assign physical libraries/drives – see Connecting and managing tape devices. Powering down the Disk Library To power down the Disk Library storage system, follow the steps below: 1. 2. 3. Stop all I/O to the Disk Library. Wait approximately 5 minutes to allow the write cache to finish its writing to the storage system. Writes may not be completed but following this procedure will ensure data integrity. From the Disk Library Console, right-click the Disk Library server and select System Maintenance > Power Down. Wait for the server to power down. Please follow the powerdown procedures for the respective storage system in the Disk Library Appliance in use.

With mirroring, each time the data is written to the virtual tape library database, the same data is simultaneously written to the mirrored copy. The disk maintains an exact copy of the database. In the event that the database is unusable, the virtual tape library seamlessly swaps to the mirrored copy. Note: The mirroring feature is already set up (factory default), if needed you can use the following procedure to enable the mirroring feature. Follow the steps below to set the mirroring feature: 1. 2. Select the Disk Library server you want and expand it. Expand Virtual Tape Library System. Right-click Database, and select Mirror > Add. The Create Virtual Tape Library Database Mirror window opens. 3. In the Create Virtual Tape Library Database Mirror window, click OK to create the virtual tape library database mirror.

Note: Licenses for optional features, such as remote copy and ACSLS are applied at the individual server level in a multi-node environment. For more information about the multi-node feature, refer to Configuring multi-node Disk Library server groupsConfiguring multi-node Disk Library server groups. Adding_an_optional_software_license Removing_an_optional_software_license 11 EDL printed help Using active-active with active engine failover The Disk Library active-active with active engine failover feature improves the availability and recoverability of the system. This feature uses two Disk Library servers that have the ability to recover from a failure of one of the servers, or from a loss of connection to one of the servers. Note: The active-active with active engine failover feature is optional on DL720, DL740, DL4200, DL4000 and standard on DL6100, and DL6300 configurations. The term engine in active engine failover refers to either one of the two, or four servers in a DL720, DL740, DL4200, DL4400, DL6100, or DL6300 respectively. The two Disk Library servers in a DL720, DL740, DL4200, DL4400, and DL6100 are peers that monitor the health of each other at regular intervals. For example, if Disk Library server A fails, then Disk Library server B will, in addition to its own emulation services, restart the emulation services that were provided by server A by taking ownership of those virtual devices and making them available to the backup hosts. Related Topics: Failover_requirements Setting_up_failover Suspending, resuming or removing failover Fibre_Channel_failover Zoning an EMC Disk Library configuration enabled for active engine failover Zoning an EMC Disk Library configuration enabled for active engine failover in a multi-fabric environment Failover options Failover_information_tab In a DL6300, the four servers are divided into two groups where Server A and B are a pair, and the Server C and D are a pair. Just as mentioned above for the DL720/740, and DL4200/4400 models, Server B can restart emulation services that were provided by the Server A. However, Servers C and D are a different pair and cannot resume emulation services for either Server A or B. To enable active-active with active engine failover in the Disk Library Console, you must purchase the failover license (failover is standard on DL6x00 series). After a failover, the active-active with active engine failover feature allows the Disk Library to re-establish the availability of the emulated devices; however, external actions will always be required to continue or restart backup operations to the Disk Library. The nature and degree of this external intervention depends on the backup software application and the operating system. When a failover occurs, the backup and restore jobs in progress to the failed server will terminate or be suspended, and will deliver a failure notification to the backup operator. This is in contrast to similar functions available with EMC storage systems that are designed to deliver transparent application level failover without any loss of data written to the storage system. This limitation is due to the nature of the backup applications and tape operation. Refer to the EMC Disk Library Release Notes for additional information. 12 Adding Optional Software and Console features About the tape shredding feature The tape shredding feature prevents specialized programs from reading data from deleted or erased virtual tapes. The tape shredding feature uses the US Department of Defense (DoD) 5220.22-M algorithm to erase data on virtual tapes by overwriting disk data with multiple patterns of bits, which makes it difficult or impossible to recover the original data. To use the tape shredding feature, see Using the tape shredding feature. Using the internal backup software inside the Disk Library This optional, licensed feature allows use of the NetWorker™ Storage Node or the Veritas Netbackup Media Server component of backup software inside the Disk Library. Note: You can install only one of the two licenses on your Disk Library at a time. It yields a Disk Library that supports all of its current functions (notably, emulating tape devices on a FC SAN). In addition, the internal backup software will use the Disk Library server resources to write to virtual and physical tape devices. A special SAN client allows virtual tape devices to be made available to the embedded internal backup software. This is especially attractive for tape duplication operations -- since the internal backup software running in the Disk Library is in charge of creating the duplicate media, the NetWorker or Netbackup software will know of the existence and location of any duplicate media. This is not the case with current Disk Library-directed duplication operations The embedded internal backup software is best used in the following scenarios: • • Local cloning / duplication – Virtual tape libraries can be shared by the production storage nodes, which generate backup save streams that are written to virtual devices in the Disk Library, and by the embedded internal backup software. When backups are complete, the embedded internal backup software can clone / duplicate these backup save sets to physical tape devices attached to the Disk Library. Remote cloning – Cloning can also occur between internal backup software-enabled Disk Library systems, such that savesets on virtual or physical tape in the local Disk Library can be cloned / duplicated via IP to a remote Disk Libraries, and then written to either physical or virtual tape. See http://Powerlink.EMC.com website for white papers on using the Networker Storage Node or the Veritas Netbackup Media Server inside the Disk Library. To start or stop the internal backup software, or to check its status, refer to topic Trees, menu options, and the main window. 13 EDL printed help Using compression Backup software products commonly use the following two compression methods: • • Client-side compression – performed by backup client software running on a backup client. Device-side compression – performed inside the tape drives. Related Topics are: Benefits_of_enabling_compression To_enable_or_disable_compression The_compression_icon The Disk Library uses device-side compression. Note: Although you can use both client-side compression and device-side compression, EMC recommends using one or the other. Using both methods will not increase your storage capacity, but will degrade the throughput of the Disk Library. The Disk Library system incorporates software compression with an LZO algorithm that runs on the Disk Library server. You can enable or disable compression for the entire Disk Library; that is, the Disk Library server compression option applies globally to all the virtual tape devices in the system. The Disk Library server compression option is disabled by default. Some backup software packages can enable or disable device-side compression. If the Disk Library compression option is disabled, then enabling or disabling the device-side compression on the backup software will have no effect. If the Disk Library server compression option is enabled, and you disable device-side compression on the backup software, then compression will be disabled only for the virtual tape devices you selected. For the DL6x00 series models, a Hardware Compression Feature is standard. This uses a hardware component within the EDL engine which will perform all compression tasks in-line. The hardware feature is used be default in lieu of software compression, however if the compression hardware should fail for any reason software compression will be used. The setting in the console for both Hardware and Software compression is the same and the system will intelligently choose hardware compression if so equipped. Note: When using Disk Library compression, all the data on a virtual tape may not fit on a physical tape counterpart when exported. This is because of better efficiency of the LZO compression method on a Disk Library compared to data compression methods on tape drives such as SDLT’s DLZ, SAIT’s ADLC, and LTO’s SDLC. Note: Hardware Compression feature is not supported on the DL2x0, DL3x0, DL7x0, and DL4x00 series models. Forwarding SNMP traps The storage system generates and sends Simple Network Management Protocol (SNMP) traps to the Disk Library server. When an event occurs on a storage system, it generates an SNMP trap that contains an event code and text that describes the error. The storage system sends the SNMP trap to the Disk Library server. The Disk Library server translates the SNMP trap and logs the event in the event log. You can view 14 Adding Optional Software and Console features the event log in the Disk Library Console. You can also configure the Disk Library Console to forward SNMP traps to an SNMP server that you specify. In the case of the DL6100 and DL6300 models the Symmetrix based storage system in these appliances will also call home to EMC separately, to notify EMC of any proactive service measures required on the storage system and notify EMC of any storage subsystem errors. To configure the Disk Library Console to forward SNMP traps: 1. 2. 3. 4. 5. • • • • • In the Disk Library Console, right-click your Disk Library server and select Properties. The Server Properties window opens. In the Server Properties window, select SNMP Maintenance. In the SysLocation field, type the location where the Disk Library server is located. In the SysContact field, type the contact details of the person providing technical support for the Disk Library server. Select the Trap Level, which specifies the type of message that will be sent. The following five levels of messages are available: None – No messages will be sent. Critical – Critical errors that stop the system from operating properly will be sent. Error – Errors (failures such as a resource is not available or an operation has failed) and critical errors will be sent. Warning – Warnings (event might require maintenance or corrective action), errors, and critical errors will be sent. Informational – Informational messages, errors, warnings, and critical error messages will be sent. When you select critical, error, warning, or informational, specify the SNMP server details as follows: a. b. 6. Click Add. The Add SNMP Details window appears. In the Add SNMP Details window, add the SNMP server name, and the community to which it belongs. Click OK. The server details will appear in the Server Properties window. Click OK. Note: You can verify that SNMP traps are set up properly. Set the Trap Level to Informational, perform a task that generates an event (such as logging into the Disk Library Console or creating a new virtual tape drive), and then check for the SNMP trap for the event. About error forwarding Error forwarding is a program that automatically contacts EMC when a problem occurs on your Disk Library. Only a qualified EMC representative can set up and access the error forwarding feature on each Disk Library. For error forwarding features on the DL2x0 series, see Enabling EDL alerts. Using the Attention Required tab If a fault occurs on a storage system that is part of your Disk Library, the Disk Library Console indicates the fault as follows: • • The Disk Library server icon is displayed with a red exclamation point. An Attention Required tab is displayed in the main window of the Disk Library Console. The following events may activate the Attention Required tab: 15 EDL printed help • • • • A fault occurs or the storage processor (SP) write cache is disabled. A Disk Library server hardware issue occurs; for example, power supply fails. A physical library goes offline. Export activities occur. The Attention Required tab disappears after you address and resolve the event. Some events may require manual clearing. Note: When you first power up the Disk Library, the write cache is disabled until the standby power supply (SPS) is fully charged. A write cache indication can last 1/2-hour or longer when you power up the Disk Library. To view the fault messages, in the Disk Library Console, 1. 2.

Enter a name for your report. Click Next. The Reports wizard opens and displays the Create the Report window. Click Finish to create the report. Note: The reports generated are available in both textual and graphical formats. You can export the textual reports to be saved as a text file. Using the standby server Note: The standby server applies only to the DL710, DL4100 , and DL210 configurations. It is not applicable to the DL720, DL740, DL4200, DL4400, DL6100 and DL6300 configurations. If your Disk Library has the standby server option, an EMC service provider has already mounted the second Disk Library server in the rack and cabled it to the storage system. Only the primary server’s power cords are connected. The power cords for the standby server should not be plugged in. 18 Adding Optional Software and Console features CAUTION: Never power up both servers simultaneously! Doing so will corrupt the Disk Library software. To use the standby server Before using the standby server, you must: 1. 2. 3. 4. 5. Consult with your EMC service provider to verify that the primary Disk Library server has developed a hardware problem. If possible, halt the primary server using the Disk Library Console. If you cannot halt the primary server, shut the primary server off. Unplug the power cords from the primary server. Plug in the standby server’s power cords and turn the standby server on. Since you can cable the primary server in different ways, the procedure for bringing the standby server completely online differs. Depending on the availability of switch ports, do one of the following: • • • Cable the corresponding ports of the primary and standby servers to the same switch (or switches). When the standby server ports come online, each assumes the WWPN of the same numbered port in the primary server. With WWPN zoning in the switch, the transition is automatic. If the switch does not have enough free ports to accommodate cables from the standby server and the primary server, you must move each front-end target port cable from the primary to the standby server. Be sure to move the cable to the corresponding port on the standby server. For HP-UX and AIX, the transition is not automatic. Move each front-end target port cable from the primary to the standby server. Be sure to move the cable to the corresponding port on the standby server. Configuring Network Time Protocol (NTP) synchronization You can configure the Disk Library server to synchronize with clocks from Network Time Protocol (NTP) time servers. Note: In the DL4200, DL4400, DL6100, and DL6300 configurations, you cannot configure NTP on the two servers if they are configured for failover. Refer to ntp.isc.org for NTP and time server information. You can configure as many as five time servers. The Disk Library server polls the configured NTP time servers and uses the most accurate time server for clock synchronization. Note: The Disk Library server must have access to external networks to be able to reach a time server. To set up NTP on a Disk Library server: 1. 2. Double-click the system time at the bottom right corner of the Console to open the Date and Time Properties window. In the Date and Time Properties window, click the NTP tab. You can add, edit, re-order, and delete servers as follows: • Click Add to add a time server to the server list. In the pop-up window, enter the time server name or IP address and click OK to add the time server. Note: The time server appears in the server list. You can add up to five time servers. • • • Click Edit to edit a selected time server name or IP address. Click Up and Down to re-order time servers in the list. Click Delete to delete a selected time server from the server list. 19 EDL printed help 3. Click OK to save changes and exit.

The welcome screen contains task description information, and appears before a number of tasks, especially those that add items to the Disk Library environments. 23 EDL printed help • Enable advanced tape creation method – Enables or disables advanced tape creation. When the advanced tape creation option is not enabled, the virtual tapes will be created with so-called capacity on demand, which allows oversubscription. Oversubscription allows you to create a larger number of tapes than there is actual storage space available, using the capacity-on-demand feature. For example, if you have 100 GB of disk storage available and you use capacity on demand with an initial allocation size of 10 GB (and a maximum size of, for example, 100 GB), you can create 10 virtual tapes. Each of these tapes will initially be 10 GB in size, and will grow when needed. If you did not use capacity on demand, you can create only one 100 GB tape. You can add disk storage on an as-needed basis so that the virtual tapes can be expanded to full size. The system logs a warning message in the activity log when the available storage space drops below 10% of the total storage space. The system checks this condition every time you create new tapes. When you enable the advanced tape creation option, a finer level of control is available when creating virtual tapes. Advanced tape creation allows you to select the disk areas that hold the virtual tapes, as well as (during virtual tape library creation) the ability to match virtual tape labels with physical tape labels. • Set Up Custom menu Capture X-Ray Console log options – Allows you to overwrite the log file, append the log file, and prevent writes to the log file.

Creating and Managing Virtual Tape Libraries Determining the number of tape libraries you need The Disk Library allows you to create and use one or several virtual tape libraries. The number of virtual tape libraries you will use in an environment depends on several factors, which include: • • • • Performance and load balancing. Backup software licensing – it may be advantageous to have several smaller virtual tape libraries, each dedicated to each backup client; alternatively, several backup clients can share one large virtual tape library. . Data isolation and protection – you may assign libraries on a per-business-unit basis. . Backup completion assurance – if you give each backup server its own virtual tape library, completion of backups is not dependent upon completion of other systems’ backups, as it is when sharing one larger tape library. Creating virtual tape libraries You can create a virtual tape library in the following two ways: • By using the Configuration wizard, see Using the Configuration wizard, which you can access by rightclicking Virtual Tape Library System and selecting Configuration wizard. Alternatively, you can click the Configure button that appears in the main window of the Disk Library Console to use the Configuration wizard. Use this method to: • • • • • Create virtual libraries. Add SAN clients and assign virtual libraries. Prepare physical tape library/drive devices. Assign physical libraries/drives. By right-clicking the Virtual Tape Libraries icon and selecting New to create a new virtual tape library. Use this method to create a new virtual tape library as follows. 1. Right-click Virtual Tape Libraries and select New. The Create Virtual Library wizard opens, and displays the Specify Virtual Library Name and Type window. 2. 3. In the Specify Virtual Library Name and Type window, select the virtual tape library type that you want to create; then you can change the default name in the Virtual Library Name field. Click Next. The Enter Virtual Drive Information window opens. In the Enter Virtual Drive Information window, select the drive type you want to use within the tape library. You can modify the Total Virtual Drives value to equal the number of tape drives you want to create within the tape library. Note: If you specify a value for Total Virtual Drives that is larger than the number of tape drives supported for that physical tape library, you will get a warning message. Some backup software products will not function correctly when the number of tape drives in the virtual tape library is larger than the number of tape drives supported in the physical tape library. Optionally, you can change the default name in Virtual Drive Name Prefix. Click Next. The Enter Virtual Library Information window opens. 37 EDL printed help 4. a. b. In the Enter Virtual Library Information window, you can optionally set up either auto archive or auto remote copy for your virtual tape library as follows: In the Enter Virtual Library Information window, click the Auto Archive/Remote Copy box. Click either Auto Archive or Auto Remote Copy. Set up optional auto archive — Auto archive automates the exporting of data to physical tapes. Any export operation of a virtual tape from a virtual tape library (such as from a backup application or another utility) starts an auto archive process. Auto archive requires that the physical tape library support bar codes. When the Disk Library server attempts to export data to a physical tape, it must find a matching barcode in a physical library. You do not need to specify which physical library. Specify either the Copy or the Move method of auto archive: Copy – Copies (retains) the contents of the virtual tape to a physical tape. Move – Moves the contents of the virtual tape to a physical tape and deletes the data from a virtual tape when the export is done. Move also allows users to specify a delay period to keep the tape in the system for a period of time before it is deleted. If you select Move, you must select a value in The grace period before deleting the tape. Select the number of days the system should wait before deleting the primary virtual tape. The Export physical tapes to I/E Slots after export option controls where the physical tape is placed after the export operation writes to it. The default is to place the physical tape back in its home slot in the physical tape library. When you select this option, the physical tape(s) will be placed in the import/export slot of the physical tape library. You can enable/disable Auto Archive anytime by right-clicking a current virtual tape library or virtual tape drive, and selecting Properties. Set up optional auto remote copy — Auto remote copy is optional software that automates the remote copy of virtual tapes to remote virtual tapes. An export of a virtual tape from a virtual tape library (such as from a backup application or another utility) starts the auto remote copy process. Specify either the Copy or the Move method of auto remote copy. Copy – Copies the contents of the primary virtual tape to a destination virtual tape and retains the data on the primary virtual tape. The data continues to reside on the appliance. Move – Moves the contents of the primary virtual tape to a destination virtual tape and deletes the data from the primary virtual tape after the export is done. If you select Move, select a value in The grace period before deleting the tape. Select how long (0-15 days) to wait before deleting the primary virtual tape. 5. Enter the Remote server name. The Disk Library Login window opens. Enter the login details for the remote Disk Library server. Click OK. Note: If the login details for the remote Disk Library server are the same as the Disk Library you are connecting from, the Disk Library Login window will not appear. 38 Creating and Managing Virtual Tape Libraries The Disk Library server on which you are creating the virtual tape library will connect to the remote Disk Library server you specified. Once the connection is established, the Enter Remote Copy Parameters window will open. 6. In the Enter Remote Copy Parameters window, enter the IP address of the target server in the Hostname of IP address field. Click Next.

Click Next. The Enter Virtual Library Information window opens. 9. In the Enter Virtual Library Information window, enter information in the following fields: Barcode Starts/Ends – Indicates a range of barcodes that will be used when creating virtual tapes. The default starting barcodes will be unique for each Disk Library. By default, barcodes increment in an alphanumeric sequence; for example, XXX0009 to XXX000A. In order to set the barcode to increment in a numeric sequence (XXX0009 to XXX0010), you have to set the last three digits of the Barcode Ends field to 999; for example, XXX0999. Slot – Maximum number of tape slots in your tape library. Note: If you specify a value for Slot that is larger than the number of slots supported for that physical tape library, you will get a warning message. Some backup software products will not function correctly when the number of slots in the virtual tape library is larger than the number of slots supported in the physical tape library. Auto Loader – This checkbox is available only when you select the IBM3590 option to create a virtual library. When the host unloads the tape from a drive, the unloaded tape is sent to the vault, and the next available tape is loaded into the drive. In a physical library, ejected tapes will not be accessible. You can, alternatively, select this option by right-clicking the IBM3590 virtual library you created and selecting Properties. The Change Virtual Library Properties window will appear. Select the Auto Loader option at the bottom. Export to physical tape – Select this option if you plan to export a virtual tape to a physical tape. The Disk Library server will limit the maximum capacity of the virtual tapes created for this virtual tape library to the uncompressed capacity of the selected media type. This allows the Disk Library server to ensure that the data on the virtual tape will fit on the physical tape during an export operation. Refer to Connecting and managing tape devices for information on setting up your physical tape library in a Disk Library environment. Import/Export Slots – Number of slots used to take tapes in and out of the tape library. After you have entered all the configuration information, click Next. 39 EDL printed help If the Enable advanced tape creation option is not set, proceed to step 11; otherwise, go to step 10. 10. In the Enter virtual tape properties window, set the following characteristics: – Tape Capacity on Demand – See Using tape capacity on demand. – Initial Tape Size – Initial size, in GB, of the new virtual tapes in this library. – Incremental Size – When the virtual tape is full, this is the amount by which to increase the virtual tape’s size, up to the maximum size (see Maximum Capacity). – Maximum Capacity – Maximum size, in GB, of the virtual tape. – Media type – Type of media in this library. After you have made the selections, click Next. The Create Virtual Library window opens. 11. In the Create Virtual Library window, review a summary of the virtual tape library characteristics you have selected. If everything is correct, click Finish, and the software creates the virtual tape library. If any information is incorrect, select Back to make the necessary changes before returning to this window to select Finish. 12. After creation of the virtual tape library, the system prompts if you want to create tapes for the library. Click Yes to perform this step now, or No to perform this step at a later time. For more information on creating virtual tapes, refer to Creating virtual tapes. Viewing virtual tape libraries To view the available virtual tape libraries in the Disk Library server: 1. 2. From Logical Resources, select Virtual Tape Library System. Virtual Tape Libraries. An expandable tree of virtual tape libraries is displayed in the Disk Library Console's tree. If you click Virtual Tape Libraries, a summary of the virtual tape libraries is displayed on the Disk Library Console’s main window (the right pane). Deleting virtual tape libraries To delete a virtual tape library: 1. 2. Right-click the virtual tape library. Select Delete Library. Note: Do not delete a virtual tape library if it has any SAN clients assigned to it. 40 Creating and Managing Virtual Tape Libraries Assigning a virtual tape library to your backup server The Disk Library ensures that only approved SAN clients can access the virtual tape libraries. A SAN client is a user-defined name that refers to the WWPN of a system connected to the same SAN as the Disk Library server. During the SAN client configuration process, you are presented with a list of WWPNs taken from the Name Server in the SAN FC switch. If your FC switch zoning is not correct, you will not obtain the SAN information, and therefore, you will not see the WWPN you expect. The SAN client will receive access to the Disk Library server resources once its WWPN is approved. Note: Under certain conditions on DL 2x0, DL7x0, and DL4x00, an operating system may detect an additional dummy device, which will appear as an FCLAR Dev device. This usually occurs when a virtual tape library is removed from your host operating system. Managing storage space of virtual tapes The Disk Library server writes virtual tapes to disk storage. When the disk storage space decreases, a message similar to the following appears: The current allocated space is n MB, which reaches n% of the total capacity. When you see this message, you must either reduce the space consumed by the existing virtual tapes, or increase the disk space available to an EMC Disk Library server. Adding a SAN client You can add a SAN client to a virtual tape library or virtual tape drive in two ways: • • From the SAN clients option From the virtual tape library Note: Make sure the SAN client (host system) is connected to the SAN, and that the FC switch zoning allows a host system to see the Disk Library server. Adding_a_SAN_client_from_the_SAN_clients_option Adding_a_SAN_client_from_the_virtual_tape_library Scanning for devices After configuring the virtual tape library and assigning it to the SAN client, you should perform a device scan on your SAN client. The steps for doing this vary according to the SAN client’s operating system. Assigning additional SAN clients To assign additional SAN clients to the Disk Library, do the following: 1. 2. 3. Expand the SAN Clients tree. Right-click the SAN client to which you want to add the virtual tape library, and select Assign. The Assign a Client wizard opens, and displays the Select Tape Libraries or Drives window. 41 EDL printed help 4. In the Select Tape Libraries or Drives window, a green dot next to a tape device indicates that the tape device is not assigned to any SAN client. A yellow dot indicates that the tape device is already assigned to at least one SAN client. Note: The list does not include virtual tape libraries to which this client already has access. The Allow tape drive(s) in the tape library to be assigned individually option allows you to assign each tape drive in the tape library to the SAN client. Select the checkbox of the library or libraries that you want to assign to the client. You can use the Select All or De-select All buttons to make the selection. Click Next. The Select a Fibre Channel Target window opens. 5. In the Select a Fibre Channel Target window, select a Fibre Channel target from the list and click Next. The Assign Tape Libraries or Drives to the SAN Client window opens. 6. In the Assign Tape Libraries or Drives to the SAN Client window, verify your choices, then select Finish to assign the tape libraries or drives to the SAN client. To replace the current tape library assignments, right-click the virtual tape library name in the Virtual Tape Libraries list, and select Assign. Using this method you can replace only existing assignments; you will not be able to add more assignments. If you want to have more than one client share a single virtual tape library, each client must go through the assign process. Unassigning a SAN client To unassign a virtual tape library or drive from a SAN client, do the following: 1. 2. 3. Right-click the SAN client. Select Unassign. A list containing available virtual tape devices is displayed. Select the virtual tape device you want to unassign, and click Unassign. Deleting a SAN client To delete a SAN client: 1. 2. Right-click the SAN client. Select Delete and click OK. Note: You cannot delete a SAN client if any virtual devices are assigned to it. Reconfiguring a SAN client with a new HBA To reconfigure a SAN client when you install a new HBA, follow the procedure below: 1. 2. 3. 42 Zone the new initiator WWPN. Unassign the virtual tape libraries and tapes that are assigned to the SAN Client, see Unassigning a SAN client. Right-click the SAN client and click on Properties. Creating and Managing Virtual Tape Libraries The Fibre Channel Client Properties window opens and displays the You can update the initiator WWPNs window. 4. 5. 6. Search for the newly zoned initiator WWPN by clicking on Rescan. The newly zoned initiator WWPN will appear in the list. Deselect the old initiator WWPN, and select the new initiator WWPN. Click OK. Reassign the virtual tape libraries and tapes to the SAN client, see Assigning additional SAN clients. Enabling compression (both hardware and software) on the virtual tape library system For compression to work on virtual tape drives, you must enable compression for the virtual tape library system. To enable compression: 1. Right-click on the Virtual Tape Library System icon and select Properties. For a DL4200, DL4400, , DL6100, and DL6300, right-click the group name, and select VTL Property. 2. In the Change Virtual Tape Library Properties pop-up, select the box Enable Virtual Tape Library compression mode, and then click OK. This enables compression on the virtual tape libraries; it does not mean that data is actually compressed. To have compression, you must set up and enable compression in your backup software. Note: A compression icon will appear on each virtual tape drive indicating that it is configured to write compressed data. 43 Connecting and Managing Tape Devices Physical tape devices In addition to the virtual devices created within the Disk Library server, the Disk Library product can optionally use physical tape devices. These devices are useful for exporting and importing. • • Exporting – Copies or moves information from virtual tapes to physical tapes. Importing – Copies information from physical tapes to virtual tapes. Connection types You can attach physical tape libraries and drives to the Fibre Channel host bus adapter in the Disk Library server. Physical Devices Preparation wizard The Physical Devices Preparation wizard's first window has the following two main options: • Prepare Device(s): Reserved for Virtual Device – Applies to disk devices and allows you to reserve the disk LUNs for use by the Disk Library server. The server will store virtual tape data on the designated LUNs. Reserved for Direct Device – Applies to physical tape libraries and allows you to reserve the tape drive and tape library devices for use as attached physical tape libraries. Unassigned - Applies to a reserved device you no longer want to use and allows you to unassign it. • Import Disk(s) – Use this option only for disaster recovery of a Disk Library server. An EMC service provider must do this. The process will import the last-saved configuration, and then import the disk LUNs. Adding physical tape devices To add the physical tape library or physical tape device, do the following: Connect the Fibre Channel cables and verify that the Disk Library can use the physical tape library or drives. Note: For Disk Library Console v2.x, the physical tape library must be attached to a SAN. To verify, do the following steps: 1. 2. 3. From Physical Resources, select Storage Devices. Select Fibre Channel Devices in the Disk Library Console. Select SCSI Devices tab in the main window. Verify that your physical devices are listed there. If they are not listed: 1. Right-click Physical Resources. 45 EDL printed help 2. Select Rescan. This initiates a scan of the Fibre Channel buses.

Select adapter 8 on DL210 for LVD-SCSI attached devices. Note: On a DL710, DL720, DL740, DL4100, DL4200, DL4400, DL6100, or DL6300, you can change the flexible-use target ports 1, 3, 7, 11 to initiator ports to connect Fibre Channel-attached devices. If you have interchanged the ports, select the appropriate one to view the Fibre Channel-attached devices. Assigning physical tape devices You can assign physical tape devices by two different methods. • The first method involves using the Configuration wizard to quickly prepare and assign physical devices. 1. 2. Select the server and click Virtual Tape Library System. Right-click and select Configuration wizard. Alternatively, you can click the Configure button that appears in the main window of the Disk Library Console to use the Configuration wizard. To configure physical tape devices, skip steps 1-3 by clicking Skip. Follow the remaining steps in the Configure Virtual Tape Library window: a. b. • Step 4: Prepare physical tape libraries/drive devices. Step 5: Assign physical libraries/drives. The second method is a detailed step-by-step manual process. This process requires you to first prepare the devices, and then assign them. To prepare the devices first: 1.

Using flexible-use ports in target mode adapter Fibre Channel adapters 4, 5, 8, and 9 are reserved for attachment of an optional Fibre Channel tape library on a DL4100, DL4200, and DL6300; On a DL4400, and DL6100 adapters, 4 and 8 are reserved for an optional Fibre Channel tape library. On a DL210 adapter, 5 is reserved for an optional Fibre Channel tape library. However, Fibre Channel adapters 4, 5, 8, and 9 are flexible-use ports: if you do not plan to use these ports for a Fibre Channel tape library, you can use them as target mode ports for SAN connections. Refer Table 4-7(Disable and Enable Target Mode options) for more information on converting the ports to target mode. Using physical tape devices with active engine failover 47 EDL printed help Physical library failover is supported for the active-active with active engine failover feature, provided that the physical library is attached to a SAN. You must adhere to the following rules for the physical library failover to work correctly: 1. 2. 3. When you zone a physical library with an initiator port on Disk Library server A (and C in a DL6300), you must also zone the corresponding initiator port on Disk Library server B (and D in a DL6300) with the physical library. When you zone a physical library with an initiator port on Disk Library server A (or C on a DL6300), you cannot zone a different physical library to the same adapter port on Disk Library server B (or D on a DL6300). After zoning is complete, discover the physical library on both the Disk Library servers, but do not configure both servers to actively access the physical library. Configure and assign the physical library on one Disk Library server only; otherwise, both the servers will have full access to all the tapes in the library and may use and overwrite each other’s tapes. This may also affect direct access mode imports if both the Disk Library servers have full access to the complete library. Note: Failure to follow the above rules may result in both Disk Library servers writing to the same tape, which could result in data loss. For additional information about failover, see section Forwarding SNMP traps. Using an EMC Disk Library as a back-end library You can connect a Disk Library as a back-end library through an EMC approved SAN FC switch to a DL710, DL720, DL740, DL210, DL4100, DL4200, DL4400 , DL6100, or DL6300; that is, you will attach a Disk Library instead of a physical tape library to a Disk Library. The icon for the back-end Disk Library will display in the Console as shown below: • • Setting up a back-end Disk Library Rescanning a Disk Library after a shutdown Configuring a Disk Library as an ACSLS client The Automated Cartridge System Library Software (ACSLS) is a storage resource management application from StorageTek. Use ACSLS to partition resources of one or more StorageTek libraries among multiple ACSLS clients. You can configure the Disk Library as an ACSLS client that supports up to 64 tape drives in a StorageTek ACSLS managed tape library. Note: An ACSLS administrator must determine the ACSLS tape library resources for an ACSLS client. Before you configure the Disk Library as an ACSLS client, obtain details such as the IP address of the ACSLS Manager, ACS ID, Pool ID, and ACSLS Drive ID(s) from the ACSLS administrator. Prerequisites • • 48 Specify a valid DNS server to resolve the name and IP address of the Disk Library server. To specify the DNS server(s) in the Console, see Setting up the network configuration in the Disk Library Console. Provide entries in the DNS server for both forward and backward lookups for the Disk Library server(s) and the ACSLS Manager server. Connecting and Managing Tape Devices • Install the Disk Library ACSLS license. To add ACSLS to your Disk Library Console, see Adding ACSLS to the Disk Library Console To configure a DL4200 or DL4400 , DL6100, and DL6300 configuration for ACSLS resource failover, see Configuring DL4200, DL4400, DL6100, and DL6300 configurations for ACSLS resource failover 49 Managing Virtual Tapes Working with virtual tapes One of the advantages of using a virtual tape library is that you can protect data on your existing physical tapes by importing them into your virtual tape system. If you need to recover files from a physical tape, you can use the import function to directly access the physical tape for immediate recovery. For long-term data archiving, you can export the data on virtual tapes to physical tapes. Using tape capacity on demand The tape capacity on demand feature allows you to allocate a small amount of space when you create your virtual tapes, and later automatically allocate additional space as needed. If you do not use this option, the Disk Library server will allocate each virtual tape at the full size of that tape. You can enable tape capacity on demand only while creating a virtual tape library or virtual tape drive. The tape capacity on demand for virtual tape libraries or drives is enabled by default. The tape capacity on demand feature will appear only if you have enabled the advanced tape creation method. Viewing virtual tapes There are several ways to view virtual tapes: • • • To display all virtual tapes in one table, select the Disk Library server. Select Virtual Tape Library System, and click the Virtual Tapes tab in the main window. To view which virtual tapes are available for use within a virtual tape library, select the virtual tape library and click the Virtual Tapes tab in the main window. To view virtual tapes in the virtual vault, select Virtual Vault. You can store virtual tapes within a virtual tape library (in storage slots, or tape drives) or in the Virtual Vault, which is similar to a physical storage area outside the tape library. Creating virtual tapes You can create virtual tapes by either enabling or disabling the advanced tape creation option. To enable, or disable, the advanced method: Select or deselect the Enable advanced tape creation method from the Disk Library Console Tools > Console Options. • • Advanced tape creation not enabledAdvanced tape creation not enabled Advanced tape creation enabledAdvanced tape creation enabled Exporting virtual tapes When you export a tape, the Disk Library copies/moves the contents of the virtual tape to a physical tape. Since some third-party backup applications alter what they write to the tape depending on the type of cartridge used, the Disk Library exports tapes only to similar media. This guarantees that the backup application will accept the tape as valid. Note: In a failover configuration, you must manually restart a failed export after a failover. 51 EDL printed help When using the auto archive option, the following must be true: • The physical library must have a physical tape with a barcode that matches the barcode of the virtual tape you are exporting. The drive type of the virtual library and physical library should match. • To export data 1. If you have not done so, inventory the physical tapes in your library/drive. i. ii. Expand Physical Tape Libraries, Right-click the physical library and select Inventory. Note: The Disk Library server performs an automatic inventory when the Disk Library server is booted, or when the physical tape library is reset. However, an automatic inventory is not performed if you scan an adapter to gather back-end physical devices that were not present when the Disk Library server booted. You must perform the inventory so that the Disk Library Console can determine the tapes in the physical tape library. If no tapes are present in the library, export and import jobs will fail. 2. 3. 4. 5. Once the inventory is complete, you can view the tapes by clicking Physical Tape Library, and selecting the physical tape library. The tape information is displayed on the right-hand side of the Console under the Physical Tapes tab. Expand the Disk Library. Select Virtual Tape Library System > Virtual Tape Libraries. Expand the required virtual tape library and right-click Tapes. Select Move to Vault. The Move Tape to Virtual Vault window opens. In the Move Tape to Virtual Vault window, select the tape(s) you want to move. You can also use the Select all or De-Select all tabs to modify your selection. Click OK to move the selected tape(s) to the Virtual Vault. This tape will no longer appear under Tapes. 6. 7. 8. To export the tape(s) in the virtual vault to a physical tape, expand the Disk Library. Select Virtual Tape Library System > Virtual Vault. Right-click the required virtual tape under Virtual Vault, and select Export Tape. The Export Virtual Tape to Physical Tape Library/Drive window opens and displays the Select a physical library or drive window. In the Select a physical library or drive window, select the physical tape library where you want to export the tape and click Next. The Select export mode window opens. 9. In the Select export mode window, select one of the following export methods: • • Copy – Copies the contents of the virtual tape to its physical counterpart and retains the virtual tape after the data is transferred. The data continues to reside on the appliance. Move – Moves the contents of the virtual tape to its physical counterpart and then removes the virtual tape from the system. The data is no longer available on the appliance. If you select Move, select a value in The grace period before deleting the tape. Select how long (in days) to wait before the deleting the tape. Note: The backup software will not be aware that the virtual tape has been removed. 52 Managing Virtual Tapes The Export Physical Tapes to I/E slots after Export checkbox controls where the physical tape is placed after it is written by the export operation. The default is to place the physical tape back in its home slot in the physical tape library. When you select this option, the physical tapes are placed in the import/export slot of the physical tape library. Note: The physical tape will not be moved into the import/export slot if the physical tape library is an ACSLS library. 10. Click Next. The Select Virtual Tape(s) window opens. 11. In the Select Virtual Tape(s) window, select the virtual tape that you want to export to the physical tape library. You will also set the barcode and the physical tape to use for export. Click Next. The Verify and Export Virtual Tape window opens. 12. In the Verify and Export Virtual Tape window, verify your selection and then click Finish to export the tape. You can monitor the progress of the operation by expanding the Disk Library, and selecting Virtual Tape Library System > Virtual Tape Libraries > Import/Export Queue. You can also examine the event log for export job events. If you set up SNMP traps at the informational level, you will get a trap when the export is complete. An export may fail if the physical tape drive encounters a media error when writing to a tape. You will have to restart the export job. If subsequent exports fail because of a medium error (see the event log or SNMP trap) on the same tape, replace the tape with another tape. When the copy from virtual tape to physical tape is complete, the Disk Library will instruct the physical tape library to place that tape back in a slot. The Disk Library will place the exported tape into the import/export slots of the tape library. This behavior allows a series of export operations to create more physical tapes than will fit in the import/export slots, allowing greater unattended export capacity. Importing physical tapes to virtual tapes Importing physical tapes to virtual tapes The import function allows you to: • • • Copy the contents of a physical tape to a virtual tape. Directly access a physical tape without copying the entire tape. Recycle a physical tape. Note: In a failover configuration, you must manually restart a failed import after a failover. To import a tape 1. 2. Expand the Disk Library. Select Virtual Tape Library System > Physical Tape Libraries. Right-click your physical tape library/drive and select Import Tape. The Import Physical Tape To Virtual Library window opens and displays the Select the virtual library to which you want to import window. 53 EDL printed help 3. 4. 5. In the Select the virtual library to which you want to import window, select the virtual library to which you want to import and click Next. The Select the import mode for importing a tape window opens. In the Select the import mode for importing a tape window, select how you want the data copied. The following methods are available: • • Copy Mode – Copies the entire contents of a physical tape to a virtual tape and leaves the physical tape unchanged. Direct Access Mode – Links a physical tape to its virtual counterpart. This gives the backup application immediate access to the tape data without waiting for a complete copy. This is useful when you need to restore a small amount of data from a physical tape. If you import a physical tape in direct access mode, and the virtual tape is subsequently initialized, the physical tape does not change, because it is write-protected. Therefore, you can only read from the physical tape and not write to it. • Recycle Mode – Allows the backup software to recycle/initialize/label a physical tape after its retention period expires. Only a small amount of data is read from the tape. This is enough data to satisfy the backup software that it has the correct tape and can recycle it. If you import a tape in recycle mode, and the virtual tape created by this process is subsequently initialized, the physical tape becomes recycled and you can use it for future export operations. Note that nothing is actually written to the physical tape. After you make your selection, click Next. The Select the physical tape to import to a virtual library window opens. 6. In the Select the physical tape to import to a virtual library window, select the physical tape(s) you want to import. You can select a tape based on its barcode or slot location. You can then use the same barcode for the virtual tape or you can enter a new barcode. After you make your selection, click Next. The Verify and Import window opens. 7. 8. In the Verify and Import window, confirm your selections. Click Finish to import the physical tape, or click Back to go back through the windows to make any changes. You can monitor the progress of the operation by: i.Expand the Disk Library. ii.From VirtualTape Library System, select Virtual Tape Libraries. iii.Select Import/Export Queue. You may also examine the event log for import job events. If you have set up SNMP traps at the informational level, you will get a trap when the import is complete. Note: When you import a physical tape, the virtual tape does not mirror the settings of the Write-Protect tab; that is, whether or not you enable the write-protect option on the physical tape, the virtual tape that is created will be write-enabled. Once the import is complete, you can set the virtual tape's write-protect option. To enable write protection on a virtual tape, right-click the tape, select Properties, and select the Enable write protection checkbox. Direct access import creates a link between a physical tape and a virtual tape. It is important to note that virtual libraries and physical libraries are not linked. In order to break a link between a physical tape and a virtual tape, the virtual tape in direct access mode needs to be moved out of the virtual tape library. You can use either the backup application or the Disk Library Console to move the tape to the virtual vault. Once you 54 Managing Virtual Tapes move the tape, the link is broken; the physical tape is moved from the physical tape drive back to its slot; and the physical tape and physical drive are freed up and available for use. Using the tape shredding feature Prerequisites: • You must move the tape to the virtual vault. To move the virtual tape to the virtual vault, refer to section Moving virtual tapes. To use the tape shredding feature: Expand the Disk Library you want, and expand Virtual Tape Library System. • To select all virtual tapes in the virtual vault: 1. Right-click Virtual Vault and select Tape Shredding > Shred Tapes. The Shred Virtual Tapes window will open. 2. 3. 4. • Select all the virtual tapes you want to shred, and click Shred. The Disk Library Console window will open. Type YES to confirm, and click OK to shred all the selected virtual tapes. Alternatively, to shred a single tape: 1. 2. 3. 4. 5. Right-click the virtual tape you want to shred. Select Tape Shredding and then the option Shred Tape. The Shred Virtual Tape Resource window will open. Check the Delete After Shredding checkbox if you want to delete the virtual tape after it is shred. Type YES to confirm, and click OK to shred the selected tape. To confirm if the tape is being shredded, you can click the virtual tape to view the status. A Tape Shredding Status will appear in the main window of the Console in the right pane with the Shredding Percent Complete status bar. Note: Using the tape shredding feature during backups may adversely affect performance. Initiate the tape shredding feature when all backups are completed. Deleting virtual tapes To delete a virtual tape: 1. 2. Expand the Disk Library, and select Virtual Tape Library System. Right-click the virtual tape, which may be under Virtual Libraries > Virtual Library Name > Tapes, or Virtual Tape Drive or Virtual Vault, and select Delete. A Delete Tape Resource window opens. 3. The Delete Tape Resource window prompts you to confirm the delete operation. If you want to proceed, type yes in the Type YES to confirm field. Note: Deleting a tape will not shred the tape. 55 EDL printed help Moving virtual tapes You can move virtual tapes among the following three locations: • • • A slot in a virtual tape library A drive in a virtual tape library, or a standalone virtual tape drive The virtual vault To move a virtual tape between these locations, right-click the virtual tape, and select either Move to Vault, Move to Slot, or Move to Drive. Remotely copying virtual tapes This section explains how to set up remote copy of virtual tapes and how to remotely copy virtual tapes. Remote copy is an optional utility that enables you to copy individual virtual tapes from one or more Disk Libraries to a remote Disk Library over an IP connection. Note: You must purchase and install remote copy licenses on both the initiator (source) and target Disk Library servers for remote copy to work. Refer to Adding and removing optional software licenses for information on how to add and remove licenses. To use remote copy, you must have at least a Gigabit Ethernet connection between the initiator and the target. EMC supports the following two remote copy configurations: • • Remotely copy from one Disk Library to one remote Disk Library Remotely copy from many Disk Libraries to one remote Disk Library Remote copy occurs only when the tape is not in use. After writing to the tape, the tape unloads from the drive (usually automatically by the backup application software). If you schedule a remote copy to occur while a tape is in use, the remote copy waits until the tape unloads. Depending on the type of remote copy configured, promotion is done automatically (for auto remote copy and remote copy) or manually using the Console (for remote copy policy). You cannot use a replica until you promote it from Replica Resources to the virtual vault. When promoted, the replica assumes the same properties (type of tape, tape size, write protection) as the source virtual tape. You can move virtual tapes that are promoted to the virtual vault to a virtual library. Related Topics: • • • • • • • • • • • 56 Types of Remote copy Setting up auto remote copy on a virtual tape library Stopping an auto remote copy Remotely copying a virtual tape Setting up remote copy policy on virtual tapes Removing a remote copy policy Viewing and changing a remote copy policy Synchronizing a primary virtual tape and a replica Suspending and resuming a remote copy policy Stopping a remote copy Viewing remote copy information for a virtual tape Managing Virtual Tapes Once promoted to a virtual library, the backup software inventories the virtual library. Depending on the backup software, you may have to import the replica virtual tape into its database to invoke a restore. Disk Library remotely copies virtual tape data, not backup software metadata. Note: The Disk Library remotely copies tapes in the virtual vault as well as tapes in the virtual libraries. When the Disk Library remotely copies a virtual tape, it temporarily marks the virtual tape read-only. Depending on the backup software, the backup may fail or the software may attempt to use other virtual tapes to write backups. Remote copy does not support fragmentation of packets by the network, and the DF (do not fragment) bit is set in the packets. All parts of the IP network must conform to the DF bit for remote copy to function. The default MTU (maximum transmission unit) size for remote copy is 1500 bytes. Externally enabling IPsec in conjunction with this MTU size may result in packet fragmentation by the network, which the EDL will not detect. To avoid this, specify an MTU size appropriate for the network environment when IPsec is enabled by the network. 57 Disk Library Event Codes Disk Library server error codes The following table provides a listing of the Disk Library server error codes that appear when there is problem with the server.

Either there is a problem with the network or the target server is busy. The replica of the virtual tape no longer exists on the target server. It might have been removed from the target server while the primary server was not available. Error occurred when adding newly discovered SCSI devices to the system. Most likely due to unreliable storage connectivity, hardware failure, or low system resources. A physical device has a different GUID written on the device header than the record in the configuration file. This is most likely caused by old drives being imported without proper initialization, due to corruption of the configuration or the device header (less likely).

If the scheduler triggers the remote copy, next remote copy will be started at the next scheduled time. Remove remote copy setup from the virtual tape console since it no longer has a valid replica. Check the storage devices for power status, controller status, and so on. Look for proper connectivity. Note that Fibre Channel switch connection status lights do not guarantee a solid connection. Disconnect/reconnect the Fibre Channel connector for verification. Verify the physical connection of the storage system. If the problem persists, call tech support. Check the storage system, including all cabling. Once the problem is corrected, rescan on the adapter with the connected drive. Limit the scope of the scan to that SCSI address. Check the storage system, including all cabling. Once the problem is corrected, rescan Disk Library Event Codes responding to commands. Its status is now set to OFFLINE. All virtual drives affected will also be set to OFFLINE. Most likely the drive or storage system is turned off, or the cable is disconnected. The physical drive geometry, including the number of sectors, are different from the original record. This is most likely caused by the storage cable being disconnected, or Fibre Channel switch re-zoning. Failure of one of the storage ports can also cause this.

Only a qualified EMC representative can set up and access the error forwarding feature on each Disk Library. For error forwarding features on the DL2x0 series, see Enabling EDL alerts. 74 Glossary A Active-active with active engine failover: A process that involves two Disk Library servers monitoring each other. In the event one Disk Library server fails, it fails over to the monitoring server, and the monitoring server takes over the identity of the failed server. Administrator: A privileged account. Only the administrator can manage the system configuration. The administrator can perform such tasks as adding disks, physical tape devices and new users, managing the import/export tapes, and setting various system preferences. B Back-end EMC Disk Library: A EMC Disk Library connecting to another Disk Library instead of a physical tape library. Backup Software Partner (BSP): A company that writes backup software products, such as Legato and Veritas. Barcode: A physical label placed on physical tapes containing both a machinereadable code (such as a UPC symbol) and equivalent human-readable information. Backup software uses barcodes to more easily keep track of tapes. Block size: Number of bytes in a tape block. Tapes do not have pre-allocated fixed-size blocks like disks, which have 512-byte sectors. C Compression: A process for using a shorter series of bytes to represent a longer series of bytes, thereby increasing both capacity and throughput. Controller: The CPU board on which the EMC Disk Library firmware runs. D Direct access import: A method for linking a physical tape to its virtual counterpart. This gives the backup application immediate access to the tape data without waiting for a complete copy. This is useful when you need to restore a small amount of data from a physical tape. E EMC Disk Library: A family of pre-configured appliances (the DL210, DL4100, DL4200, and the DL4400, DL6100, and the DL6300), each consisting of a rack containing a storage system and an Intel-based server. 75 EDL printed help EMC Disk Library appliance: The EMC Disk Library server and all of the physical disks and physical tape drives used by the EMC Disk Library server. Error forwarding: A program that automatically contacts EMC when a problem occurs on your EMC Disk Library. Events: Incidents that are recorded in the event log when an item of interest to the administrator occurs. An event may or may not have an associated action request. Export request: An instruction to a virtual library to export a virtual tape. You can export a virtual tape by sending a SCSI command to the virtual library (usually from a backup application) or by using the EMC Disk Library console interface. The export request will track the process of exporting the data from the virtual tape. F Failover: See Active-active with active engine failover. Foreign disk: A virtualized physical device containing EMC Disk Library logical resources previously set up on a different Disk Library server. I I/O device: An addressable input/output unit, such as a disk device. Identifier (ID): A sequence of bits or characters that identifies a program, device, controller, or system. Import request: A method for tracking the process of importing data from the physical tape. You can import a virtual tape by sending a SCSI command to the virtual library or by using the EMC Disk Library Console. An administrator or any other user can create an import request. Initiator: A Disk Library port that connects to the attached EMC storage system. M Media: The disk surface on which data is stored. Mirror: A duplicate copy of the virtual resource database, providing redundancy and thereby reducing the chance of data loss. O Oversubscription: The ability to create more virtual tapes than actual storage space available, using the capacity-on-demand feature. P 76 Glossary Physical disk: A disk connected to the EMC Disk Library server. All data is stored on the physical disks. Physical tape: A physical piece of tape media. It is called physical tape to clearly differentiate it from a virtual tape. Physical tape drive: Drives connected to the EMC Disk Library server. They may be connected through either a Fibre Channel or parallel SCSI connection (in the case of the DL210 System). The physical tape drives transfer the data from the virtual tape to a physical tape. The data is read during import and written during export. Recovery R Recovery: The process of restoring the failed server’s identity from the monitoring server after a failover. Replica: An exact copy of a virtual tape, created on a remote system over an IP (Internet Protocol) link. S SAN client: A system on the SAN that will access the EMC Disk Library’s virtual tape devices. T Takeover: The process of a monitoring server taking over the identity of the failed server in the event of a failure. Target: A port that connects to the SAN to which backup servers are connected. V Virtual library: The logical equivalent of a physical tape library. Like a physical tape library, a virtual library has one or more tape drives, tape cartridge slots, mailbox entry and exit ports, a barcode reader, and a media changer. Virtual library type: A virtual library, determined by the number of slots, number of virtual tape drives, and the type of virtual tape drives. EMC Disk Library has several predefined virtual library types. The administrator can create additional virtual library types if required. Virtual tape: A logical representation of a physical tape. Virtual tapes are used inside virtual libraries. Virtual tape drives write to them in the same way as physical tapes. When you create virtual tapes for a specific virtual library, they are defined by the virtual tape drives used for that library. 77 EDL printed help Virtual tape cartridge: A container for data written to and read from a virtual tape drive. This resides on one or more LUNs and is managed by the EMC Disk Library software. Virtual tape drive: A logical equivalent of a physical tape drive. Virtual tape drives are configured within virtual libraries. A virtual library can have one or more virtual tape drives. Like virtual libraries, virtual tape drives are defined by a generic type. In this case, the drive type defines the drive that is being created. This includes the type of physical drive that it will identify itself as and the capacity of the drive's media. Virtual tape drive type: A virtual tape drive format created based on a physical tape drive. EMC Disk Library has several pre-defined virtual tape drive types. The administrator may create additional tape drive types if required. Virtual vault: A holding place for virtual tapes that have been exported from a virtual tape library. 78 Index A Auto remote copy ..........................56 Accessing the Disk Library server through
