Figure 36 iSCSI VT advanced LUN mapping

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.

The 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:

Type Date Auth User defined

A Microsoft-created IQN includes microsoft and the system name:

iqn.2003-11.com.microsoft:win2k-sn-192168101

Figure 37 shows an iSCSI gateway that has three iSCSI VTs and two iSCSI initiators.
