Checking the Server Environment
Connection to servers is possible in the following environments.
Check the "Server Support Matrix" for server environment conditions.
2.1
Hardware
Access the following documents or use the "Server Support Matrix" to determine which models are compatible with which servers.
• Search the VMware Compatibility Guide
http://www.vmware.com/resources/compatibility/search.php
2.2
SAS Cards
Refer to the "Server Support Matrix".
2.3
Connection Compatibility of ETERNUS DX Storage Systems to
VMware ESX
Access the following web-site to check which ETERNUS DX models may be connected to VMware ESX:
• Search the VMware Compatibility Guide
http://www.vmware.com/resources/compatibility/search.php
2.4
Virtual Machine
Virtual Machine is a virtual machine created on the VMware ESX server.
Details of how to install an OS on the VMware ESX Virtual Machine may be checked via the following URL:

Chapter 3
Notes
Note the following issues when connecting the ETERNUS DX to a server.
3.1
VMware ESX Operating Notes
• Refer to the following web-site for the number of LUNs that VMware ESX can recognize.
http://www.vmware.com/support/pubs/
• When Windows® is used on the Virtual Machine, the registry will need to be modified after Windows® is
installed. For details, refer to "Chapter 7 Virtual Machine" (page 21).
• The VMware ESX multipath function supports path failover, meaning that server access can continue unaffected by any problems that might arise in the SAS cables. It should be noted that path failover can fail to
occur when multiple SCSI sense codes are repeatedly and simultaneously received.
• ETERNUS Multipath Driver and GR Multipath Driver do not need to be installed on a VMware ESX Virtual
Machine. The multipath function of VMware ESX provides path redundancy.
3.2
ETERNUS DX Setup Notes
• When connecting a VMware ESX server to the ETERNUS DX, check that the firmware version is as specified
in the "Server Support Matrix".
• Host Response must be set before connecting the ETERNUS DX to VMware ESX.
• Assign Affinity Group values starting from LUN0 in ascending order. The server cannot recognize the ETERNUS DX LUNs if some other assignment order is used.
• When LUNs are shared among multiple physical servers (in a vMotion configuration, for example), an Affinity Group mapping should be used to ensure that each shared LUN is assigned the same LUN number
across every physical server.
• When connecting to VMware ESX with multiple paths sharing a single LUN, a Reset Group setting is required for the ETERNUS DX device.
• Details of dynamic recognition of LUNs added while VMware ESX is running are given in the "Chapter
8 Dynamic Recognition of LUNs Added While VMware ESX is in Use" (page 23).
3.3
SAN Boot Notes
• All ETERNUS DX storage systems support SAN Boot.
• VMware ESX calls SAN Boot to "Boot From a SAN". "Boot From a SAN" means to boot the VMware ESX server
from a Storage Area Network (SAN).

Chapter 3 Notes
3.4 Server Startup and Power Supply Control Notes
3.4
Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS DX storage systems are all "Ready". If the server is
turned on and they are not "Ready", the server will not be able to recognize the ETERNUS DX storage systems.
Also, when the ETERNUS DX power supply is being controlled by a connected server, make sure that the
ETERNUS DX does not shut down before the connected servers. If turned off, data writes from the running
server cannot be saved to the ETERNUS DX storage systems, and already saved data may also be affected.

For VMware vSphere 6.0
The following procedure describes how to check LUN recognition using the vSphere Web Client.
Check the LUNs from the vSphere Web Client.
The procedure is as follows:
1
Log in to the vSphere Web Client and select in order, [Hosts and Clusters] > target host.
2
Select in order, the [Manage] tab > [Storage] > [Storage Adapters].
3
Select [Rescan...].
After selecting [Rescan...], the VMware ESX should attempt to recognize the ETERNUS DX storage systems' LUNs again.
