It provides a solution that is easy to install, manage, service, and support. The enterprise-level features include Unified Snapshots, Multicore Cache, Multicore RAID, FAST Cache, FAST VP, and many other provisioning and monitoring features that support a wide range of workloads such as databases, files, and virtual machines. Along with enhanced native iSCSI protocol support, the VNXe3200 also supports Fibre Channel (FC) protocol, and expanded IPv6 functionality. The VNXe3200 delivers up to 3 times the performance of a VNXe3150 system. The VNXe3200 Disk Processor Enclosure (DPE) contains two Storage Processors in the 2U rack mount form factor: • 25-drive DPEs paired with 2.5" disks. • 12-drive DPEs paired with 3.5" disks. Each storage processor features an Intel Xeon Quad Core 2.2-GHz processor, 24 Gb of internal memory (DIMM), two integrated 6-Gb/s mini-SAS HD ports, four integrated 10-GbE iSCSI Base-T ports, and one slot for an optional I/O module. Similar to the existing models, VNXe3200 also supports hot swappable 2.5"/3.5" SAS and NL-SAS rotating disks, and 2.5" Flash disks in the DPE and optional 12-disk or 25-disk Disk Array Enclosures (DAEs). The VNXe3200 also supports NFS, CIFS, iSCSI through the embedded I/O ports, and FC protocols through optional I/O modules. Note: VNXe Operating Environment (OE) Version 3.1 is only supported on the VNXe3200. Do not use the OE Version 3.1 on the VNXe3100, VNXe3150, or VNXe3300. New features and changes This document contains the following new features and changes: Upgrade enhancements Although VNXe OE Version 3.1.1.5395470 is identical to the previously released VNXe OE Versions 3.1.1.5134075, 3.1.1.4993502, and 3.1.1.4823793, this version contains additional enhancements that make the upgrade process more reliable. It also includes a new driver firmware that improves future firmware upgrade processes. Multiprotocol file access The multiprotocol feature lets you create and manage multiprotocol NAS servers and file systems that support file sharing by users in Windows and UNIX environments. UNIX users can access the file system data using NFS, and Windows users can access the same file system data using CIFS. This release contains the following multiprotocol-related enhancements: • 2 VNXe3200 Release Notes Ability to map UNIX user accounts to Windows user accounts. The system automatically maps a Windows user to a UNIX user when the same user name New features and changes is defined in the Unix Directory Service (UDS) and Windows Active Directory (AD). If the user names are different, you can modify and upload an ntxmap configuration file template to create a custom mapping between them. This mapping can contain wildcards and substitution sequences. To allow users with unmapped user names to access a multiprotocol NAS server's file systems, you can create default UNIX and Windows users on the NAS server. • Ability to use LDAP or NIS as a Unix Directory Service to map users, retrieve netgroups, and build UNIX credentials. • Unified file-level security policy management for multiprotocol access, including support for NFS credentials with more than16 groups. When you configure a multiprotocol file system, you can choose the type of access policy to use for that file system: Unix Security, which uses the UNIX credential associated with the host request to check mode bits. Windows Security, which uses the Windows credential associated with the host request to check the CIFS Access Control List(ACL) Native, which uses the protocol's security (ACLs for CIFS and mode bits for NFS) to manage host access to shared data. Note: When you upgrade an older VNXe system, all file systems will retain their current type (CIFS or NFS), and existing NAS servers will have multiprotocolmode disabled. Also, once you enable a NAS server for multiprotocol access, you cannot disable it. Data protection enhancements This release contains the following data protection enhancements: • Native asynchronous replication support for LUNs, LUN groups, and VMware VMFS datastores • Replication support for block-based storage resources using RecoverPoint • Snapshot of snapshots for 32-bit VMware NFS datastores Native asynchronous replication support for block-based storage resources VNXe now supports asynchronous replication for block-based storage resources (LUNs, LUN groups, and VMware VMFS datastores). Both Unisphere and the CLI have been updated to provide interfaces for the easy configuration and management of replication sessions on storage resources. This feature leverages crash consistent replicas to provide remote data protection of storage resources. It relies on the Unified Snapshot technology, and provides a cost-effective and easy solution without any dependency on additional software. Replication support for block-based storage resources using RecoverPoint In addition to the native asynchronous replication support, VNXe now also supports replication for block-based storage resources using EMC RecoverPoint 4.1.1. RecoverPoint brings you continuous data protection and continuous remote replication for on-demand protection and recovery at any point in time. This remote replication technology can run on a physical appliance (RPA) or a virtual appliance VNXe3200 Release Notes 3 New features and changes (vRPA). Both synchronous and asynchronous replication modes are supported. RecoverPoint can also be used to replicate block-based storage resources between VNXe3200 and VNX systems. Snapshot of snapshots for 32-bit VMware NFS datastores 32-bit VMware NFS datastores, created after upgrading to this release, now automatically include support for second-level snapshots at the file level. Using VMware vStorage APIs for Array Integration (VAAI), you can create a fast clone of a previously created fast clone at the virtual machine level. 64-bit VMware NFS datastores also support second-level snapshots. NAS server enhancements This release contains the following NAS server enhancements: • Ability to create up to 10 IP interfaces per NAS server • IPv4 and IPv6 preferred interfaces to be used for general outbound traffic initiated by the NAS server • Ability to create a NAS server that supports multiprotocol file system access. Ability to create up to 10 IP interfaces per NAS server In this release, you can create up to 10 IP interfaces per NAS server using IPv4, IPv6, or both. This provides the ability to expose one NAS server to different IP subnets that can be used for testing or other purposes. It also enables SMB 3.0 Multichannel support for CIFS. Preferred interfaces When you create IP interfaces for a NAS server, the first IPv4 interface and first IPv6 interface configured with a gateway become preferred interfaces. The NAS server uses the preferred interface gateways for outgoing communication with non-locally connected hosts. For example, the NAS server forwards DNS and Active Directory requests through a preferred interface and uses the same IP address as a source address of the packets. Note: Locally connected hosts, which are attached to the same subnets as the NAS server interfaces, are accessed through corresponding interfaces directly, and not through the preferred interface gateways. When a NAS server initiates outbound traffic, it compiles a list of all the available network interfaces on the proper subnet and performs one of the following actions: • If a preferred interface is in the compiled list, the NAS server chooses the preferred interface. • If a preferred interface is not in the compiled list, the NAS server chooses a network interface at random. 4 VNXe3200 Release Notes New features and changes SMI-S enhancements This release contains the following Storage Management Initiative Specification (SMI-S) enhancements: • Integration with Microsoft System Center Virtual Machine Manager (SCVMM) next generation. • Support for the profiles defined in SMI-S standard v1.6.0.4. For more information about SMI-S, see the SMI-S Provider Programmer's Guide for VNXe. Integration with Microsoft SCVMM next generation You can now use the SMI-S API to set up local and remote LUN mirroring, which allows the system to integrate with Microsoft SCVMM 2012 R2 to support the Azure Site Recovery Service. In addition, this release allows you to use the SMI-S API to configure LUN storage tiering, expose access point information, and list and monitor fan and power supply health. Support for profiles defined in the SMI-S standard v1.6.0.4 This release supports the following new profiles and subprofile defined in SMI-S standard v1.6.0.4: • Access Points Subprofile • Automated Storage Tiering Profile • Fan Profile • Power Supply Profile • Replication Services Profile (mirror part) Storage efficiency enhancements This release contains the following storage efficiency enhancements: • 64-bit format for VMware NFS datastores • Shrink and space reclaim for 64-bit VMware NFS datastores • Fast clones for 64-bit VMware NFS datastores • Support for 400 GB FAST Cache 64-bit format for VMware NFS datastores You can now create and manage 64-bit VMware NFS datastores, also known as UFS64. UFS64 provides a number of benefits over existing 32-bit datastores (UFS32), including: • Increased scalability • Improved resiliency/recoverability • Improved availability • Enhanced storage efficiency VNXe3200 Release Notes 5 New features and changes To learn more about performance expectations, refer to the VNXe3200 Best Practices for Performance white paper for VNXe Operating Environment Version 3.1.1. Shrink and space reclaim for 64-bit VMware NFS datastores You can now shrink the size of a 64-bit VMware NFS datastore (UFS64) without affecting its accessibility. The shrink operation reduces the space the datastore uses from the storage pool, which allows the storage pool to reclaim space. With thinprovisioned VMware NFS UFS64 datastores, you can shrink into the allocated size. Fast clones for 64-bit VMware NFS datastores For virtual machines using the 64-bit VMware NFS datastores, you can now create at least 1024 fast clones. Each fast clone can have up to 256 snapshots. Support for 400 GB FAST Cache If you have a FAST Cache license and have the necessary SAS FLASH disks available, you can now configure the FAST Cache to use up to 400 GB of space. This enables to you get a better performance from the FAST Cache in your environment. The FAST Cache is configured in RAID 1 pairs, and you can have various disk configuration options. For more information on the disk configuration options, see the Unisphere Online Help. User experience enhancements This release contains the following user experience enhancements: • Ability to display pool consumption information for all allocated resources in a storage pool • Support for single sign-on from Unisphere Central or another VNXe Unisphere instance • Display of warning-level messages in the Pre-upgrade Health Check. These flag system issues that you may need to check or correct before proceeding with an upgrade. • Enhanced progress bar for software upgrades that more accurately reflects the upgrade status. • User-friendly object name support Display pool consumption data for all allocated resources in a storage pool You can now display and export pool consumption data for all allocated resources in a storage pool by using the new Storage resources tab of the pool's details page. This tab displays the following information about the resources (NAS servers, LUN groups, LUNs, file systems, and VMware datastores) allocated to a pool: • Snapshot size, which is the total amount of pool space allocated for the snapshots of the storage resource. • Total pool size used, which is the total amount of pool space allocated for the storage resource, including its primary data, snapshot data, and metadata. Having this type of data in one place can help you more effectively manage storage pools. For example, you can use this data to narrow down the cause of pool degradation, take measures if the pool is running out of space, and view pool 6 VNXe3200 Release Notes New features and changes resources before-purposing a pool. Single sign-on from Unisphere Central or another VNXe Unisphere instance This release supports Single Sign-On (SSO) VNXe authentication from the Unisphere Central GUI and the GUI of another VNXe system. With SSO, you can: • Log into the Unisphere Central GUI and launch one or more Unisphere GUIs for VNXe systems without re-authenticating. • Log into a VNXe GUI, open another browser window, and launch another VNXe system by entering the URL for that system. (You do not have to reauthenticate to open the second VNXe system.) For information about setting up single sign-on support, see the VNXe Security Configuration Guide. User-friendly object name support You can now use the name to retrieve and display historical and real-time performance metrics for a LUN, file system, disk, pool, Ethernet port, iSCSI, and FC objects when you issue the VNXe Unisphere CLI metrics command. Provide the userfriendly object name as the unique object identifier in the –path object qualifier of the /metrics/value/hist and /metrics/value/rt commands. Other enhancements This release contains the following other enhancements: • Serviceability enhancements • Hardware enhancements • SLES11 Refresh Serviceability enhancements • Audit logs are now created for all service related actions. Some of the existing audit log entries have also been enhanced for a better user experience. • You can now include customer contact information with ConnectEMC dial home messages. This helps ensure that EMC Support has the most accurate information for contacting you in response to an issue. Hardware enhancements • The storage system now supports the use of DC power supply. • The following I/O modules are now supported: 4 port 1Gbps iSCSI front end 10GBaseT (copper) - This interface can negotiate to 10Mbps, 100Mbps, or 1000 Mbps. 4 port 10Gbps iSCSI front end optical - This interface is a hardware/driver bundle that provides optical support connectivity through 10GbE SFP or Active and Passive Twin-Ax cables. Both modules support 256 initiators per port. They support a maximum of 8 VLANs per port. VNXe3200 Release Notes 7 Fixed problems SLES11 Refresh This refresh ensures the system remains current with the latest OS distribution, makes best use of the SUSE, and receives the latest security updates. Pacemaker is the High Availability (HA) component from SUSE with updates to match the SUSE distribution. Fixed problems This release contains the following fixed issues: Priority Symptom Description Fix Summary Tracking Number P01 The system rebooted with the following stack: The issue was fixed in the code. 622806 handle_fault+0x1d _ZN9rodLayout9sendBreakEjyy+0x12f 4File_LocksData26checkConflictWith RangeLoc N14File_LocksData13checkConflictER 14lockCred P01 A panic occurs during a rename with symbolic link. The issue was fixed in the code. 625384 P01 An outage occurs due to Block CIFS threads because the CAVA server does not answer to a scan request but still answers to the heartbeat. A parameter was added to the code that sets a timeout for MSRPC scan requests to 5 minutes. 625755 P01 When the CAVA signature changed, a free page is not available with VirusChecker and scan on read is enabled. If the high water mark is reached, the caller thread is blocked. The code has been fixed to use an open file with “scan on read” enabled to start the scan. 625759/ 59556484 P01 The system stopped sending the client IP in some events. The code has been fixed to add the client IP to all system events. 625762 P01 The system and file server rebooted when the Continuous Availability of the SMB3 protocol was implemented. The Continuous Availability service has been fixed to restore SMB3 persistent state accordingly. 626466/ 58673698 P01 A race condition between the I/O operation and the file deletion caused a file service thread deadlock. The issue was fixed in the CFS lock manager in the critical code path. 626480/ 58596446 P01 With unmodified data and the parameter cifs.windowsTimeUpdate set, the modification time of a file is updated after a rename or a setSD. The modification time is unchanged after a rename or a setSD. 626495/ 58605798 8 VNXe3200 Release Notes Fixed problems Priority Symptom Description Fix Summary Tracking Number P01 NFS mount is unresponsive. After a while, the system rebooted with all the mount threads blocked. The conditions that triggered this issue are fixed. 626497/ 59135856 P01 The system can reboot when accessing the NFSv4 client table and the NFSv4 service has stopped. The issue was fixed in the code. 626503/ 61114502 P01 The NAS server experienced an NFS security issue. The NFS security issue has been fixed. 626504/ 61102304 P01 Unable to set/unset offline DOS attribute bit independently of DHSM. This issue has now been fixed. 628477/ 57894086 P01 When running the nas_fs translate Control Station command to convert a file system access policy from UNIX or secure to mixed, the system rebooted. The issue was fixed in the code. 628711/ 628714/ 628713 P01 The system rebooted with Hyper-V and an error appeared. The issue was fixed in the code. 631620 P01 The system rebooted because there was not a free page. The issue was fixed in the code. 634570/ 49662840 P01 The system can reboot in NIS code while the default domain is removed. The code has been updated to harden NIS code to ensure the NIS objects are always valid before using them. 639848/ 52090850 P01 Users cannot delete a LUN group with snapshots in one operation. Delete all snapshots and then delete the LUN group. 640616 P01 A “SPN mismatch” warning message did not display when: Updated the SPN mismatch code to detect a mismatch between the host name and the domain name. 641623/ • A Kerberos system used a Fully Qualified Domain Name (FQDN) • The host name and the CIFS server had the same name • The domain name was different 11111111 P01 If using an SMB2 client for NAS access, and an SP on the VNXe rebooted, the client can stop responding before recognizing that the VNXe has failed over. Use a more modern client with SMB3. 646014 P01 String buffer size is not set to right length and caused an overwrite and reboot. The issue was fixed in the code. 648895/ 62007318 VNXe3200 Release Notes 9 Fixed problems Priority Symptom Description Fix Summary Tracking Number P01 The LUN names must be unique across the system. You can only create 100 LUNs for the given LUN name. If there are no free LUN names in the range, the GUI mistakenly accepts the empty strings "" as the names and sends them to the backend for validation. The backend responds with an error. The issue was fixed in the code. 649175 P01 An error message appeared when creating a snapshot of a file system, LUN, or LUN Group object with the GUI, or using the "/prot/snap", "/prot/snap/nfs" or "/prot/snap/cifs" UEM CLI commands. This issue was fixed in the code. 651348 P01 The NAS server crashed when setting a NFSV4 ACL on a file with no Security Descriptor. The conditions which triggered the crash have been fixed. 652510/ 62789772 P01 The system reboots when mounting a file system and trying to convert the UNIX mount path into Unicode. The code has been updated to set a pointer to the shadow directory to null. 654480/ 63917158 P01 A corrupted SMB request contained a length field larger than the remaining data in the request. A data conversion issue caused the boundary check to overflow and a very large memory allocation failed, causing the NAS server to reboot. The data conversion issue was fixed. 670574/ 59848028 P01 A Service Principal Name (SPN) was specified with an incorrect format. The 'empty' service name field caused a NAS server to reboot. The format of the SPN confirmed both a service name and a host name are included. An error appeared if the SPN is not the correct format. 670859/ 60584052 P01 An issue with error handling during NFS request processing prevented memory from being freed correctly, which lead to the out of memory condition. This issue has been resolved by properly releasing the memory. 670892 P01 The thin file system is fully extended after a system reboot (for example, after upgrade) and the deduplication scan failed due to the low high water mark (hwm). The assumption for size of the UFS32 mount string is incorrect under some condition. It could cause the ufs32 mount string to be truncated. In this case the hwm=75 is truncated to hwm=7, which is not expected. The code has been fixed to have enough buffer for max possible length. 690807 P01 In some cases, an error may occur when users try populating a thin-provisioned file system. This may have occurred because of an issue with the automatic extend feature. This issue has been fixed in the code. 713438/ 69843634 10 VNXe3200 Release Notes Fixed problems Priority Symptom Description Fix Summary Tracking Number P01 Modifying access permissions on any ESX host in Unisphere resulted in the datastore getting unmounted from all other ESX hosts. This issue has been fixed in the code. 719122/ 69825372 P02 The replication destination appears as the destination choice of another replication session. This transient issue resolves after the internal poll on a remote system is complete. 462661 After using Unisphere to create a replication session between the source object A on system ABC to destination object B on system DEF, attempts to create another session from source object C on system ABC to an object on system DEF will show the recommended destination objects list of the already inuse destination object B as a possible destination choice. This leads to confusion as B on system DEF is already part of a replication session. P02 CAVA sends incorrect notifications with null as the file owner. The code has been updated to obtain the SID before releasing the file_namingnode. 625751/ 56617316 P02 The 'Null owner SID' in some CEPP events Owner SID does not set in some CEPP XML requests. When attempting to open a file or a directory to which you do not have rights because the file_namingnode is not present, you cannot obtain the SID file/dir. 625752 The code has been update to retrieve the SID before freeing the file_namingnode. When open or mkdir failed, send preevent with the fnn if possible in order to get the ' owner SID ' of the file/directory. P02 Rename with SMB2/SMB3 does not trigger a VirusChecker scan. The code has been updated to check if the file has been renamed using set file info rename. 625757 P02 When renaming with SMB2/SMB3, there is no trigger for the virus checker scan. The code has been updated to ensure that the file has been renamed using the set file info rename. 625758/ 59402998 VNXe3200 Release Notes 11 Fixed problems Priority Symptom Description Fix Summary Tracking Number P02 When enumerating open sessions or open files on a CIFS server that belonged to a system with many servers, the reports can include information that belonged to other CIFS servers. Ensure the information is related to the audited CIFS server. 626183/ 60397558 P02 CIFS clients cannot access a file on an EMC Share for a lock conflict reason. The file system unmounted or freeze operation stopped responding. The lock manager is fixed to properly handle a race condition so that no range lock object is left on the file. 626478/ 59688542 P02 Error messages appeared frequently in the server log. This code has been fixed to properly handle multiple sessions from a single CIFS client. 626483/ 59361952 P02 When the user mapping service has not started or not configured on a Linux client, access is unavailable through NFSV4. The server string cannot be interpreted. This issue was fixed in the code. 626498/ 59549160 P02 Cannot access the system with NFSv4 from a system that used UDP or NFSv4. The server returned an incorrect error. The issue was fixed in code to automatically switch to NFSv3. 626500/ 58917286 P02 On a very old Microsoft operating system (DOS), if directory enumeration used all filter bits including VOLUME, the VNXe system did not return any entry. The filter on volume bit was too restrictive, and implemented for DOS 6.22. The code has been updated to manage the VOLULME filter is to return no entry only if the search criteria is exclusively for VOLUME information. 628540 P02 When a new file or directory was created by a UNIX system in a parent directory with both the UNIX setgid bit set and a Windows Access Control List (ACL) with a group security identifier (SID), the primary group SID of the new file or directory was not set to the SID of the parent directory. This error occurred on a multiprotocol file system mounted with MIXED access checking policy and ntcredential (generate Windows credentials) enabled. Fixed the code to use the group SID of the parent directory in this case. 628709/ 55983968 P02 Windows audit auto-archive did not work if: This issue was fixed in code. 628716/ 5803220 • The Windows audit auto-archive is enabled in a NAS server but not on the system • The system tried to restart or unload/load the NAS server. 12 VNXe3200 Release Notes Fixed problems Priority Symptom Description Fix Summary Tracking Number P02 The system can reboot when: The issue was fixed in the code. 628728 • Changing the location of the Windows security event logging file to a full file system • Restarting a NAS server with the event auto- archive feature enabled. The auto-archive files that are not well configured can saturate the audit file system P02 Windows 8 or 8.1 and W2012/R2 servers can lose access to a Data Mover CIFS share when browsing the server UNC path \\<server or IP>. The code has been update to add the FSCTL_DFS_GET_REFERRALS_EX SMB2 IOCTL support for SMB3. 628748 P02 When the “All” option is used on NetWorker NDMP, the backup stopped because of a snapshot create failure on the/.etc file system. To avoid this issue, do not use “All” option; specify each file system separately. 633167 P02 After changing admin password for a CIFS client connection, the original credential can be still available in Kerberos cache. This can cause a password mismatch and the DHSM cannot recall the intended data. After setting a new password, bypass the Kerberos cache and locate the valid TGT from Kerberos server directly. 634565/ 45255446 P02 The Restore option in Windows Explorer does not work when used with C$ path. The code has been update to handle the path access in shadow_base.cxx=>ShadowDir ectoryBase::parsePathname( ) in a similar manner as an NMFS component. 638753/ 47151218 P02 When a symbolic link is created with NFSV4 in a file-system mounted in a MIXED access policy, any user can delete it. This issue was fixed in the code. An ACL is generated on the symbolic link. Only users having Write permission on the directory are allowed to delete the symbolic link. 640159/ 58131932 P02 A previous version of a deleted file cannot be retrieved from Windows if wide links are enabled. Retrieve the previous version of the file on a regular Windows server or through the .ckpt directory. 641501/ 57873800 P02 The windows security log can be unreadable if a bad UNIX event log was generated. The file name included in a generated log can be truncated or invalid. This issue was fixed in the code. 641503/ 56016464 VNXe3200 Release Notes 13 Fixed problems Tracking Number Priority Symptom Description Fix Summary P02 YP requests can stop indefinitely when the domain is removed while some requests are processed. Fix bad error codes that are returned when the domain is undefined in the function. Determine if any YP request must be tried again. 641545/ 61583520 P02 If you discover multiple standalone ESX hosts and add them in a single operation, some of the hosts failed if the login credentials are different for each of the hosts. Add standalone ESX hosts one at a time. 651252/ 63924250 P02 When a user attempts to add standalone ESX hosts using the host name present in DNS, the requests can fail if: Update the host names and domain information on the ESX servers to match the host name entries on the DNS server. 651648/ 63924250 When the DHMS server does not exist, an error appeared stating, “The ASA server does not exist.” An error does not appear if: 653291 P02 An error appeared stating the intermittent data is unavailable on CIFS Share. This issue was fixed in the code. 654188/ 60876796 P02 When the CIFS server is a member of too many groups, CIFS users cannot map to the CIFS server share by name. Support larger DNS T_KEY query message (more than 8K) to establish the secure context with the DNS server when the CIFS server account includes many groups. 654897/ 62112774 P02 Unable to configure FT file bigger than current max size of 100MB. This issue has been fixed in the code. 658497/ 60261046 P02 Deduplication functionality was lost when 74.25% to 75% of the current allocation space of a thin-provisioned file system was used. The code has been updated to use the correct parameter in the free space threshold. 663695/ 65183732 P02 Invalid CEPP event sent when opening a file to read attributes. The code has been updated to send CEPP_OPEN_FILE_NOACCESS event when opening file to read attributes. 664804 P02 Users were unable to upgrade to OE Version 3.1.1.4993502. This issue has been fixed in the code. 713756/ 713766/ 713758/ 69876906 P02 • The host name on one or more of the hosts to be added does not match the host name present on the DNS server. • The host name is not set and still has the default value “localhost”. 14 VNXe3200 Release Notes • The ASA check box is cleared. • A new DHMS server object does not pass to the backend. Known problems and limitations Priority Symptom Description Fix Summary Tracking Number P02 The data mover received an LDAP response missing several bytes. An uninitialized static object appeared. The NAs server rebooted and tried to delete the static object. This issue has been fixed in the code. 670528/ 52344416 P03 You cannot use any non-ASCII name in snapCLI as these names could leave the system in an unconfigurable state. This issue has been fixed in the code. 626485/ 622109 Known problems and limitations The following known problems and limitations have been identified in this release: Tracking Number Priority Symptom Description Workaround Summary P01 When a large size system is configured with multiple file systems, checkpoints, protocols, and so on, data failover (DU) and data failback (DU) can take more than 60 seconds to complete. There is no workaround for this issue. 665247 P01 When users modify access rights to allow the ESX host to access VMware VMFS datastore for the first time, the VNXe system requests the ESX host to lay a VMFS partition on the VMFS datastore. This can cause a data loss when the VMFS partition is the result of a replicated VMFS datastore. The VNXe system only requests the ESX to lay a VMFS partition when ESX hosts are given access to VMware VMFS datastores and when the user creates VMFS datastores through the Unisphere GUI. 672984 If a user modifies access rights on an existing VMware VMFS datastores to allow access to ESX hosts, the VNXe system will only share the storage with the ESX host, but not request the ESX to lay a VMFS partition. There is no workaround for this 686875 issue. P01 Degradation in performance may occur when replicating data to a VNXe3200 using RecoverPoint. P01 When upgrading from one 3.1.1.x VNXe software There is no workaround for this 692533 version to another 3.1.1.x version, thinissue. provisioned file systems may extend unexpectedly for the duration of the upgrade. VNXe3200 Release Notes 15 Known problems and limitations Tracking Number Priority Symptom Description Workaround Summary P01 When replication synchronization is in progress and the SP reboots, the replication session can become inactive and the system may go into a Critical health state. If the synchronization was triggered by a manual synchronization or failback command, the command may fail with an I/O error. To recover from this situation, users can pause and resume the operation as suggested by System Health and Alert recommendations. 698020 P01 When an SP fails over, the mgmtd service may restart. Although users may notice a core dump for the mgmtd service in such circumstances, this happens occasionally and the service restart does not affect any other operations. 701773 P01 In an environment that has synchronous replication set up for LUNs and asynchronous replication set up for VMware VMFS datastores, the VMware vCenter Site Recovery Manager (SRM) based "reprotect" operation for the synchronous replication may fail. This occurs because of an issue with the "Element Pairs" property of the asynchronous replication set up for the VMware VMFS datastores on the system. Try the following: 705008 1. Identify and delete the asynchronous replication session(s) associated with the VMware VMFS datastore that is causing the failure: a. To identify, run the following UEM CLI command, and note the replication sessions that do not include the Element Pairs information. uemcli -u <user> -p <passwd> /prot/rep/session show –detail b. To delete, run the following UEM CLI command for each of the identified sessions that display this behavior. uemcli -u <user> p <passwd> /prot/rep/session -id <session-id> delete 2. Run the SRM "reprotect" operation again. 16 VNXe3200 Release Notes Known problems and limitations Priority Symptom Description Workaround Summary P01 If you create a NAS server with an IPv6 interface, delete it, and try creating a NAS server again, the operation may fail. This occurs because the associated Linux-based routing tables for the IPv6 address remain on the system even after the NAS server was deleted. For such NAS servers, automatic failback and subsequent failover operations may also fail. Try removing the IPv6 interface before manually deleting the NAS server. This will ensure that the Linux-based routing tables are cleared. Tracking Number 708936 In the case of automatic NAS server removal during a failback operation, restore the network configuration by manually fixing the relevant tables from the Linux console. This means that automatic NAS server failback is disabled for NAS servers with IPv6 interfaces. In failover situations for such NAS servers, contact your service provider to clean up the affected routing tables. P02 System health checks may fail with flr::check_if_storage_pool_recove ry_is_required_2 error condition when upgrading the operating environment software. Add more LUNs to the pool, or skip the Pre-Upgrade Health Check (PUHC). 637235 P02 The usable capacity of a file system is less than the size they specify. With a small file system, a large portion of space cannot be used. There is no workaround for this issue. The space required for the metadata throughout the lifecycle of UFS64/UFS32 file system may increase as the file system fills up. 674992 UFS64 has a different layout than UFS32 and has more metadata overhead. Both metadata and user data space is removed. For example, if the user creates a 3GB UFS64 file system, then actual usable space is less compared to UFS32 file system. This difference would generally be noticeable for small file systems, such as file systems with a few Gigabytes (GBs) space. P02 In replication use cases, the Create Host wizard displays storage system FC initiators on the FC access page. The page should only display host Fibre initiators. There is no workaround for this issue. 676546 VNXe3200 Release Notes 17 Known problems and limitations Tracking Number Priority Symptom Description Workaround Summary P02 The prot/rep/session show command stops responding (more than 30 minutes) if one site is down. Wait for request to timeout, and reestablish connectivity with the remote system. Once connectivity is reestablished, the /prot/rep/session command will report updated session information. 680959 P02 The amount free space reported is not always accurate. Therefore, users may think there is more space available than actual available space. To avoid this issue, create a file system smaller in than the free space reported by the system. 683278 P02 When the name of the datastore in Unisphere is different from name of corresponding datastore on the ESX server, the virtual machines and virtual disks hosted by the datastore may not show up under the Virtual Machines tab on properties page of that datastore in Unisphere. Ensure that the name of the datastore on the ESX server is the same as the name of corresponding datastore in Unisphere. 683733 P02 During the RecoverPoint software installation in a virtual RPA ISCSI environment, the following warning message may appear: RPA failed to see any LUN on the array. Please check zoning and LUN mapping If this occurs, wait two minutes and press refresh in the RecoverPoint Deployment Manager to rescan LUN. 687264 P02 After a pool is recovered, creation of a file system may hang. Cancel the file system creation job. Create the file system again approximately half an hour after the recovery. 693474 P02 When configuring replication using the Replication Wizard in Unisphere, the Select Destination step may report an error with the list of remote storage resources. The remote resources are not shown and the error reports that the system was unable to retrieve this information. Manually find the destination storage resource by clicking the Unisphere Refresh button on this step. 694167 P02 When changing a Block-based storage resource (such as a LUN) to a replication destination, host access is automatically disabled. Thus, the Change to Read-Only button on the Replication tab does not apply. No workaround. 695515 P02 When in service mode, the UI does not timeout. Close the browser. 696015 There is not a fix or workaround for this issue. 18 VNXe3200 Release Notes Known problems and limitations Priority Symptom Description Workaround Summary Tracking Number P02 A false error message may display warning users that the asynchronous replication connection was lost. For example: "2015-01-12T04:44:08.872Z" "spb" "System_A" "4129" "N/A" "ERROR" "14:6076c" :: "Communication with replication host FNM12345678 has been lost" :: Category=User Component=Health To verify the connection: 698836 -or2015-01-12T04:44:09.056Z" "spb" "System_A" "4129" "N/A" "CRIT" "14:60516" :: "System FNM12345678 has experienced one or more problems that have had a major impact" :: Category=User Component=Health P03 P03 If a language pack is erroneously uploaded to the Software tab, the upload will fail with an error directing the user to use the Languages tab. However, the first attempt to upload the language pack to the Languages tab will fail with a “corruption” error message. When adding a set of hosts where two or more have duplicate IQNs, one of the hosts successfully logged in and the other attempted logins that are rejected at a high rate. This rejection resulted in SP reboots, no access to storage and performance, and degraded hosts. 1. Click Hosts > Replication Connections. 2. Select the system ID for which the error was reported from the list, and click Verify and Update Connection. False error messages will automatically clear within approximately 3 minutes of being displayed. Attempt to upload the language pack to the Languages tab a second time. 653930 Ensure that you assign correct, unique IQNs to each host connected to the VNXe3200. 655970/ 64430424 VNXe3200 Release Notes 19 Known problems and limitations Priority Symptom Description Workaround Summary P03 The replication connection or replication session operation fails after a software upgrade or SP reboot, and the following message appears. The remote system failed synchronous connection validation. Ensure the fibre channel connection is up and rerun the verify operation to resolve the issue. Complete the following steps from Port Settings in Unisphere or with the following command in the CLI: /net/port/fc -id <value> set -speed <value> 1. 3. Ensure that the FC cabling and zoning configuration is set up correctly. The exact words in the message vary based on the FC configuration. Tracking Number 665148 4. Change the FC port speed on Port 0 from 8 Gbps to 4 Gbps. 5. Switch back to 8 Gbps on SP A and SP B of the source and destination systems to trigger a new FC login process. 6. Run the operation that failed again. If the same error message reappears, use the following procedure to restart management services and reenable the sync replication connection between systems. 2. 1. Log in to the Unisphere GUI. 2. Select Settings > Service System to enter the password for the service, and then click Continue. 3. Select Restart Management Software from the navigation menu in the right pane. 4. Click the Execute Service Action P03 P03 The replication session displays a NonRecoverable Error state or Lost Sync Communication states after a power on, reboot, or panic of the SP(s). Pause, and then resume the session to change it to an Active state. Make sure that both SPs are up and running. The source and destination storage resources should have the same SP owner. If a health check fails from the GUI for the Online Disk Firmware Upgrade (ODFU), there is no way to restart the upgrade if the health check fails with a warning. Resolve the issue that is causing the health check to fail and try again, or use the CLI to restart the upgrade. 20 VNXe3200 Release Notes 668397 673112 Known problems and limitations Tracking Number Priority Symptom Description Workaround Summary P03 Using a VNXe VSS hardware provider and diskshadow to create a shadow copy and the following error appears: \DISKSHADOW> create The last operation failed. Returned HRESULT: 80042314 - Error text: VSS_E_HOLD_WRITES_TIMEOUT Reduce the number of concurrent initiate paths to the resource. P03 The user tries to create an asynchronous replication session and the following error appears: 4, Job failed with error: Execution Errors: Replication Internal Error (Error Code:0x9881) Wait a few minutes and retry the operation. If the issue still persists, contact your service provider. 678536 P03 When the source LUN size is not 8k-aligned, the replication session goes into nonrecoverable-error state during synchronization. There no workaround for this issue. 678707 P03 The following error message may appear when opening Unisphere: Pre-login startup service failed. Launch another web browser to access Unisphere. 679311 P01 The user cannot connect to Unisphere using the Fully Qualified Domain Name (FQDN) of the VNXe system. Do not add a trailing dot “.” at the end of the FQDN with the HTTPS. If there is a trailing dot, remove it and try again. You can also use the IP address to connect to Unisphere. 589382 P01 If vCenter makes network connections to the storage system, this surpasses the web server's connection limit and you cannot connect to the array with other clients such as Unisphere or UEMCLI. Complete one of the following actions: 617184 678530 If issues persist and PowerPath is in use, switch to MPIO. • Remove and add the array's Storage Provider again in vCenter. • Reboot vCenter Server and restart the management service. • Upgrade vCenter to the most recent patch release. Refer to EMC Knowledge Base article emc185241 P01 When attempting to add a VASA Provider to VMware vCenter, the operation fails with the "Vmomi.Fault.InvalidArgument" error. Update the VMware vCenter's SMS certificate. For more information, refer to VMware documentation. 620675 VNXe3200 Release Notes 21 Known problems and limitations Tracking Number Priority Symptom Description Workaround Summary P01 If an SP reboots while creating a snapshot, the new snapshot can be in an "Offline" state. Delete the newly created snapshot that is in an "Offline" state using the Unisphere GUI or CLI. You can create another snapshot again at the same time. 623354 P01 If the user moves the DAEs across backend buses (hot) the system reports a fault indicating the DAE is missing. Reboot the SPs to clear the system. 623630 P02 The user can create two or more hosts with the same name manually or same name can be created by the user and by the system. Users can modify names of the hosts they created. 556807 P02 The EMC NetWorker stops responding if snapshot creation fails on VNXe3200. Identify and fix the root cause for the snapshot failure. Try running the backup from the NetWorker again. 622251 P02 If the user renames a VMware VMFS datastore that is unmounted from one or more ESX hosts, and mounts the datastore again, vCenter does not reflect the new name. The user can manually rename the datastore in vCenter to fix the discrepancy. 622975 P02 When viewing the list of VMware hosts in Unisphere, the total number of datastores reported for an ESX host may not match the number of datastores displayed when expanding the ESX tree node. Expand the ESX node. The associated datastore is listed for each virtual machine running on the ESX. 623309 P02 Snapshot names cannot contain spaces. To delimit words in snapshot names, use alternative characters such as an underscore "_". 623879 P02 When uploading the upgrade file to the system using Internet Explorer (IE8 or IE10), the progress dialog box that indicates the upload value appears up to a certain percentage, such as 7%, and then disappears. The % complete never appears again. After about 60 to 90 seconds, the processing file dialog box appears. While the file uploaded correctly, the disappearing dialog box may cause confusion. Use web browsers other than Internet Explorer. 624649 P02 The NFS resource graphic does not correctly display the free capacity amount. The user can use an NFS client to confirm the exact amount of free space in the file system. 626524 22 VNXe3200 Release Notes Known problems and limitations Tracking Number Priority Symptom Description Workaround Summary P02 The size of a thin-provisioned file system may increase automatically after the upgrade. This action functions as designed. During the upgrade, the file system size is set to the current allocated size. Once the upgrade process is complete, the file system size is restored to the original size and the current allocation increases by a small amount. 723951 P03 An error occurs when the user tries to map an Active Directory (AD) group to a Unisphere role with an identical name in multiple domains. This action is a known behavior and does not impact performance. 573054 P03 If you add an ESX server through Unisphere (Hosts > Hosts > Create Hosts), VMware datastore name change is not effective on the ESX server. VMware integration works well when vCenter detects the ESX host (Hosts > VMware Hosts > Find ESX hosts). If you add an ESX server, the VMware datastore rename automatically changes the name on the ESX server. 596775 P03 The non-ASCII names created on Unisphere may not display correctly on VSI (Virtual Storage Integrator). VSI supports only ASCII characters. If you have implemented VSI, use only ASCII characters. 604216 P03 After a firmware update, a message indicating a failure may appear. The following message appears in the log after the BMC comes back online after the firmware upgrades: 611993/ 611997 SPB Suitcase 0 environment interface failure cleared. P03 While performing a software update through Unisphere, the progress bar may become unresponsive. Wait about 10 minutes and refresh the Unisphere browser session. Log in again. If the problem persists, contact EMC service. 619374 VNXe3200 Release Notes 23 Technical notes Technical notes Required update EMC recommends that you keep your VNXe system up to date by upgrading to the latest software version at your earliest opportunity.
