Specifies whether volumes will automatically use the volume name as the iSCSI target alias (yes, the default).
If you disable this capability (no), you must manually specify an alias for a volume if you want one. (It is not required that you use an alias.) Changing the group-wide setting will not affect existing volumes.
You can override the group-wide setting for a specific volume by using the volume create command or the volume select command.
Format
