Chapter 3Notes

Note the following issues when connecting the ETERNUS DX to a server.

3.1 Connection Notes

To ensure reliable access to the ETERNUS DX storage systems, the following methods are recommended:

• VMware multipath plug-in

• Connection via multiple paths

• Balancing of active paths

LUN0

LUN1

VMware ESX

Cable

Example configurationwith optimized load

balancing of the LUNs

CM#0 CA#0 Port#0 CM#1 CA#0 Port#0

Active path#1(to LUN0)

Active path#2(to LUN1)

SAS card SAS card

VMware multipath plug-in

Setting up multiple access paths between the server and the ETERNUS DX creates a multipath configura-tion. A multipath configuration provides improved access redundancy.

For VMware multipath plug-in details, refer to "3.6 VMware Multipath Plug-in" (page 11).

9FUJITSU Storage ETERNUS DX Configuration Guide -Server Connection- (SAS) for VMware® ESX

Copyright 2019 FUJITSU LIMITEDP3AM-3462-22ENZ0

3.2 VMware ESX Operating Notes

• Refer to the following web-site for the number of LUNs that VMware ESX can recognize.

https://www.vmware.com/support/pubs/

• When Windows® is used on the Virtual Machine, the registry will need to be modified after Windows® isinstalled. For details, refer to "Chapter 7 Virtual Machine" (page 23).

• The VMware ESX multipath function supports path failover, meaning that server access can continue unaf-fected by any problems that might arise in the SAS cables. It should be noted that path failover can fail tooccur 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 VirtualMachine. The multipath function of VMware ESX provides path redundancy.

3.3 ETERNUS DX Setup Notes

• When connecting a VMware ESX server to the ETERNUS DX, check that the firmware version is as specifiedin the "Server Support Matrix".

• Host Response must be set before connecting the ETERNUS DX to VMware ESX.

• When LUNs are shared among multiple physical servers (in a VMotion configuration, for example), an Af-finity Group mapping should be used to ensure that each shared LUN is assigned the same LUN numberacross every physical server.

• When connecting to VMware ESX with multiple paths sharing a single LUN, a Reset Group setting is re-quired for the ETERNUS DX device.

• Details of dynamic recognition of LUNs added while VMware ESX is running are given in the "Chapter8 Dynamic Recognition of LUNs Added While VMware ESX is in Use" (page 25).

3.4 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 serverfrom a Storage Area Network (SAN).

3.5 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 isturned 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 theETERNUS DX does not shut down before the connected servers. If turned off, data writes from the runningserver cannot be saved to the ETERNUS DX storage systems, and already saved data may also be affected.

3.6 VMware Multipath Plug-in

For improved system reliability, installing the VMware multipath plug-in for the ETERNUS DX is recommen-ded. The VMware multipath plug-in can prevent access from being stopped when a path fails by optimizingthe VMware multipath's path fail-over function for the ETERNUS DX. For setting details, refer to "6.4 Plug-inSettings" (page 21).

For details on how to obtain VMware Multi-Pathing plug-in for ETERNUS, contact your sales representative.

3.7 Notes on Startup Failures for Windows® Virtual Machines us-ing EFI

If a SCSI command that exceeds the maximum I/O size set in the ETERNUS DX is sent from the VMware EFIfirmware, Windows® virtual machines fail to start up.

This is because the value of the maximum I/O size set in the VMware EFI firmware differ from the ETERNUSDX.

To avoid this problem, change the value of Disk.DiskMaxIOSize to 7992.

For more details, refer to the VMware web-site for KB2146167.
