options to delete a LUN or LUNs where,
-t target_IQN Specifies the IQN name for the iSCSI VT in the format:

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
