Changing and displaying the 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. You may create a different IQN prefix

using the iscsiswcfg - -modifygw -t <tgtname> command. The prefix portion may be used to identify

companies or organizations (e.g., Brocade, Microsoft, etc.). Your organization may suggest or

require a specific format for the prefix portion of the IQN.

To change the IQN prefix

1. Connect and log in to the switch.

2. Enter the iscsiswCfg - -modifygw -t <tgtname> command, where <tgtname> is the value you

want to use as the IQN prefix.

The following is an example.

IscsiSaturn1:root>iscsiswcfg --modifygw -t iqn.2007-10.com.brocade
