The IQN value is an iSCSI Qualified Name entered in the form type.date.naming authority:user_defined. The following is an example, using the Brocade default for the type.date.naming authority: prefix portion of the IQN, followed by a WWN as the user defined portion. Type Date Auth User defined iqn.2002-12.com.brocade:10:00:00:05:1e:aa:bb:cc Every iSCSI initiator and iSCSI VT on the same IP network and SAN must have a unique IQN. The default for the type.date.naming authority: prefix portion may be changed using the iscsiSwCfg --modifygw -t tgtname command. Your organization may suggest or require a specific format for the prefix portion of the IQN. The user defined portion may take any form. The following is an example. switch:admin> iscsicfg --create tgt -t iqn.2002-12.com.brocade:example-disk001 The operation completed successfully. 3. Enter the iscsiCfg --show tgt command with the -t IQN and -v options to verify the iSCSI VTs.
