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 follow-
ing iSCSI connection setup.
Example connection configuration
3.2 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 38)
.
• The VMware ESX multipath function supports path failover, meaning that server access can
continue unaffected 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: "RoundRobin" is recommended
- For VMware Infrastructure 3: "Fixed"
• ETERNUS Multipath Driver and GR Multipath Driver do not need to be installed on the
VMware ESX Virtual Machine. Multipath function of VMware ESX provides path redundancy.
