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