Mapping FC targets to iSCSI VTs

-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.2006-10.com.example:disk001:

switch:admin> iscsicfg --add lun -t iqn.2006-10.com.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.2006-10.com.example:disk001

Number of targets found: 1

Target: iqn.2006-10.com.example:disk001

Number of LUN Maps: 2

Deleting LUNs from an existing iSCSI VT

The iscsiCfg --delete lun command can be used to delete LUNs from an existing iSCSI VT. The

command can be used to delete individual LUNs, a list or range of LUNs, or all LUNs associated

with an iSCSI VT.

To delete LUNs from 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.

IscsiSaturn1:root>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” later in this chapter for extra detail on the commit process.
