Overview of iSCSI FC zoning
FIGURE 9
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.
For more information on configuring a zone, see "Creating and Maintaining Zones" in the Fabric OS
Administrator's Guide.
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.
