270 iSCSI Gateway services
6. Issue the iscsiCfg --show lun command with –t <IQN> options to verify that the LUN has been
added to the iSCSI VT, where -t is the IQN that identifies the iSCSI VT.
For example.
switch:admin> iscsicfg --show lun -t iqn.2002-12.com.brocade:example-disk001
Number of targets found: 1
Target: iqn.2006-10.com.example:disk001
Number of LUN Maps: 1

Mapping LUNs on a specific port to an iSCSI VT
1. Connect to the switch and log in.
2. Issue the iscsiCfg --add lun command with –t <IQN>, –w <port WWN>, and –l <n:n>
options to add LUNs attached to a specific port device to an iSCSI VT where:
• -t specifies the unique IQN name for the iSCSI VT in the format:
iqn.2002-12.com.brocade:<user_defined_name>.
• -w specifies the port WWN of the physical FC target.
• -l maps the physical FC LUNs to virtual iSCSI LUNs and is specified as a pair:
LUNs:physical LUNs
The following example maps two LUNs attached to port 2f:ff:00:06:2b:0d:12:99 to an iSCSI VT
named iqn.2002-12.com.brocade:example-disk001:
switch:admin> iscsicfg --add lun -t iqn.2002-12.com.brocade:example-disk001 \
-w 2f:ff:00:06:2b:0d:12:99 -l 1-2:0-1
The operation completed successfully.
switch:admin> iscsicfg --show lun -t iqn.2002-12.com.brocade:example-disk001
Number of targets found: 1
Target: iqn.2002-12.com.brocade:example-disk001

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. Issue 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.
For example:
switch:admin>iscsicfg --delete lun -t iqn.2005-10.com.brocade:tgt1 -l 2-4,5
