Creating an iSCSI FC zone

To create an iSCSI FC zone, you must include the following iSCSI elements in the zone:

• The FC targets, used to create the virtual targets (VT)

• The iSCSI virtual initiators (VIs):

- If there is more than one FC4-16IP blade in the chassis, you must add all virtual initiators

to the same zone.

- If there is more than one FC4-16IP blade in the fabric, you must add all virtual initiators

from all switches to the same zone.

- If connection redirection is not used, only the VI correlating to the iSCSI target portal used

by the host(s) needs to be used.

- If connection redirection is used all 8 VIs for the FC4-16IP blade must be used.

- If the iSCSI host(s) are accessing the VT from more than one FC4-16IP blade in the chassis

(MPIO), you must add all virtual initiators to the same zone.

- If the iSCSI host(s) are accessing the VT from more than one FC4-16IP blade in the fabric

(MPIO), you must add all virtual initiators from all switches to the same zone.

Although you can add the iSCSI FC target and virtual initiator to an existing zone, it is advisable to

create a separate zone so that iSCSI gateway service components can be easily differentiated from

other devices in SAN fabric zones.

The following procedures describe the commands to run to get the iSCSI information you must

provide during the zone creation process.

NOTE

You must install Brocade Advanced Zoning licenses on all the switches in the fabric before

attempting to configure zones. The Brocade 48000 must have the zoning license installed.

To display WWN information for FC targets and initiators

1. Log in to the director.

2. Enter the following command to display the WWN information for the following FC targets:

switch:admin> iscsicfg --show lun

Number of targets found: 2

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

Number of LUN Maps: 2

FC WWN Virtual LUN(s) Physical LUN(s)

21:00:00:04:cf:e7:73:7e 0 0

2f:ff:00:06:2b:0d:12:99 1-2 0-1

Target: iqn.2002-10.com.brocade:21:00:00:04:cf:e7:74:cf

Number of LUN Maps: 1

FC WWN Virtual LUN(s) Physical LUN(s)

21:00:00:04:cf:e7:74:cf 0 0x0000000000000000

switch:admin>

3. Save the FC WWN information for each LUN, which you will need during the zone creation

process.
