iSCSI component identification of the IQN prefix

Unique 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

+--++-------+ +------+ +---- -----------------+

iqn.2002-12.com.brocade:10:00:00:05:1e:aa:bb:cc

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

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

The following figure shows an iSCSI gateway that has three iSCSI VTs and two iSCSI initiators.
