318 iSCSI gateway service
Deleting LUNs from an iSCSI VT
You can delete individual LUNs, a list or range of LUNs, or all LUNs associated with an iSCSI VT.
1. Connect to the switch and log in.
2. Enter the iscsiCfg
--delete lun command with –t <target_IQN>, –w <port_WWN>, and
–l <LUN_list> options to delete LUNs,
where:
-t <target_IQN>Specifies the IQN name for the iSCSI VT in the format:
iqn.2002-12.com.brocade:<user_defined_name>, where user_defined_name
may be any unique string up to 12 alpha-numeric characters long.
-w <port_WWN> Specifies the port WWN of the physical FC target. If this parameter is used without
using -l to identify LUNs for deletion, all LUNs for the specified iSCSI VT are deleted,
and the FC target is removed from the iSCSI VT mapping.
-l <LUN_list>Specifies the LUN or LUNs that you want to delete. This can be an individual
number, and mix of numbers, or a range. The LUNs must be in the existing target data
base.
The following is an example.
switch:admin>iscsicfg --delete lun -t iqn.2005-10.com.brocade:tgt1 -l
2-4,5
The operation completed successfully
3. Enter the iscsiCfg
--commit all command to commit the changes to the database. If the LUN
deletion is one of several configuration changes, you may want to see ”Committing the iSCSI-related
configuration” on page 322 for extra detail on the commit process.
Displaying the iSCSI virtual target LUN map
1. Connect and log in to the switch.
2. Enter the iscsiCfg
--show lun command:
switch:admin> iscsicfg --show lun

Displaying iSCSI VT state and status
The following information can be displayed 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.
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
