324 iSCSI gateway service
Figure 40 iSCSI gateway service in an iSCSI FC zone
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. 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.
