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 a LUN or 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 refer to “Committing the
iSCSI-related configuration” for extra detail on the commit process.
Displaying the iSCSI virtual target LUN map

2. Enter the iscsiCfg
