Notes

VMware ESX Operating Notes

3.1.2

For VMware Infrastructure 3

Dedicated IP addresses must be allocated to the iSCSI LAN. An IP address must be allocated to each VMkernel

that corresponds to an iSCSI Initiator, and a LAN card and VMkernel must be connected via a virtual switch.

For example, a total of six IP addresses are required by the following iSCSI connection setup.

Example connection configuration

VMkernel (iSCSI Software Initiator)

IP address (1)

IP address for Service Console (2)

IP address

for iSCSI port (5)

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

installed. For details, refer to

The VMware ESX multipath function supports path failover, meaning that server access can continue unaf-

•

fected by any problems that might arise in the iSCSI cables or LAN switches. It should be noted that path

failover can fail to occur when multiple SCSI sense codes are repeatedly and simultaneously received.

Set the "Path Selection Policy" (per-LUN) as follows:

•

For VMware vSphere

For the ETERNUS DX Disk storage system

•

"RoundRobin" is recommended

For VMware Infrastructure 3

"Fixed"

•

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.

For improved system reliability, installing the VMware multipath plug-in for the ETERNUS DX Disk storage

system is recommended. The VMware multipath plug-in for the ETERNUS DX Disk storage system can pre-

vent access from being stopped when a path fails by optimizing the VMware multipath's path fail-over

function for the ETERNUS DX Disk storage system. For details, refer to
