Displaying iSCSI VT state and status
This section explains how to list all the iSCSI VTs on the fabric. The following information is shown
for each iSCSI VT.
• Name—IQN for the iSCSI VT
• State—Whether the FC target is online or offline
• Status—Whether the iSCSI VT has been defined (configuration completed but not committed)
or is committed (active and available to iSCSI initiators)
• Authentication method—Indicates CHAP if authentication is enabled for the iSCSI VT
To display iSCSI VTs
1. Connect and log in to the switch.
2. Enter the iscsiCfg
--show tgt command with the -v option to display the iSCSI VTs:
switch:admin> iscsicfg --show tgt -v

Configuring discovery domains
This section explains how to configure access control between iSCSI initiators and iSCSI VTs
manually using discovery domains and discovery domain sets configured on the fabric.
If iSNS (internet storage name service) is enabled, then configure access control on the iSNS
server; discovery domains and discovery domain sets configured in Fabric OS are not supported if
the iSNS service is enabled on the fabric.
NOTE
If you do not configure either discovery domains or iSNS for access control, then any iSCSI initiator
on the IP network can access all iSCSI VTs (and therefore all FC targets) in the fabric.
