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. To learn more about these operations, see "About Zones" in the HP StorageWorks Fabric OS 6.2.x administrator guide and the zoneCreate command in the Fabric OS Command Reference. For more information on configuring a zone, see "Creating and Maintaining Zones" in the HP StorageWorks Fabric OS 6.2.x administrator guide. 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. 324 iSCSI gateway service
