Creating a LUN o

When creating a LUN on an EVA G L running VCS 3.028 to present to an iSCSI initiator, the LUN’s
preferred path properties must be set to either Path (controller) A or Path (controller) B.
When an EVA GL is running VCS 3.028 firmware, the controllers are configured in Active/P assive mode.
Because a LUN is not presented out of a ll EVA ports, you need to set a p referred path to ensure that the
LUN is availab
le from a specific controller or from a known iSCSI EVA target p ort.
If th e LUN is cr
eated with no prefer ences and if the initiator logs into the wrong EVA target port, the LUN
may not be available to the initiator. The initiator must log into the EVA target p ort that is presenting the
LUN.
Workaround
To ensure that the iSCSI initiator logs into the correct EVA target port:
1. Present only that EVA target port to the initiator. If multiple EVA target ports ar e presented,
only log into the active EVA target p ort. Select from one of the following operating systems to
set the iqn name:
• For Windows—log in to the correct active target iqn name.
•ForLinux—settheTargetName in /etc/iscsi.conf to the active target iqn name.
2. Cross-reference the preferred path EV A controller with the correct EV A target port by comparing
the preferred path controller’s Host Port WWPN with the last 16 characters of the EVA target
iqn name.
