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. iS C S I virtual target 1 LUN 0 1 2 F C target 1 LUN 0 1 2 3 4 5 iS C S I virtual target 2 LUN 0 iS C S I virtual target 3 LUN 0 F C target 2 LUN 20 21 22 23 24 25 Figure 21 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:. 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: 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 Fabric OS 6.1.x administrator guide 255
