Advanced LUN mapping
SCSI VTs can be mapped to more than one physical FC target, and the LUNs can be mapped to different
virtual LUNs.

Unique iSCSI Qualified Names (IQNs) are used to identify each iSCSI VT. The format for the IQN is

iSCSI gateway service supports IQN only to identify the iSCSI components, such as the iSCSI initiator and
iSCSI VT. Every iSCSI initiator and iSCSI VT on the same network and SAN must have a unique IQN.
