iSCSI FC zoning overview

FIGURE 37 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, 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. To learn more about these operations, see
“About Zones” in the Fabric OS Administrator’s 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 Fabric OS
Administrator’s Guide.
ATTENTION
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.
iSCSI FC zone creation
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).
