276 iSCSI Gateway services
• Issue the fcLunQuery command with the -s option to return the node and port WWNs of the switch.
The following is an example.
switch:admin> fclunquery -s
The following WWNs will be used for any lun query from this switch:
Node WWN: 10:00:00:60:69:80:04:4a
Port WWN: 21:fd:00:60:69:80:04:4a
iSCSI FC zoning overview
After you have finished setting up the iSCSI target gateway, you can create an iSCSI FC zone for discovery
domains. However, if you do not have a zoning license, or if zoning is not implemented, you cannot create
an iSCSI FC zone for discovery domains.
Depending on whether you have an effective zone configuration enabled in the current fabric, you will be
able to choose where to put the iSCSI FC zone. It can be either contained in a defined configuration or
integrated into the effective configuration. Figure 25 illustrates a defined iSCSI FC Zone containing iSCSI
virtual initiators and FC targets.

If default zoning is set to No Access, you must create an iSCSI FC zone so that the devices can talk to each
other.
If default zoning is set to All Access with no effective zone configuration, you can create an iSCSI FC zone
and add it to a defined configuration, but you do not need to enable the defined configuration. In this
case, all devices can talk to each other already. However, to avoid future congestion in the SAN, you
should implement a zoning plan for the devices.
When you execute the cfgClear or cfgDisable commands, discovery domains and discovery domain
sets are not deleted.
You can create zones, add and remove members from a zone, and delete zones. These zone operations
function the same way with iSCSI as without. See the zoneCreate command in the Fabric OS Command
Reference.
For more information on configuring a zone, see ”Creating and maintaining zones” on page 209.
IMPORTANT: If you decide to start zoning the devices, you must create zones for all the devices in the
SAN or you will not be able to access the devices that are not in a zone.
