• Enter 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 23 illustrates a defined iSCSI FC Zone containing iSCSI virtual initiators and FC targets.

If default zoning is set to All Access with no effective zone configuration, then 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. 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.
