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. Figure 21 shows an advanced mapping scenario.

iSCSI component identification

IQN Prefix

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

type.date.naming authority:<user_defined>. The type.date.naming authority portion is a

fixed prefix. The default prefix is

iqn.2002-12.com.brocade.

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.

A Brocade-created IQN includes 2002-12.com.brocade and the device WWN as shown in the following

example:
