386 Administering Advanced Zoning
Creating and modifying Zoning configurations
You can store a number of zones in a Zoning configuration database. The maximum number of items that
can be stored in the Zoning configuration database depends on the following criteria:
• Number of switches in the fabric.
• Whether or not interoperability mode is enabled.
• Number of bytes per item. The number of bytes required for an item depends on the specifics of the
fabric, but cannot exceed 64 bytes per item.
When enabling a new zone configuration, you must ensure that the size of the configuration does not
exceed the minimum size supported by all switches in the fabric. This is particularly important if and when
you downgrade to a Fabric OS that supports a smaller zone database than the current Fabric OS. In this
scenario, the zone database in the current Fabric OS would have to be changed to the smaller zone
database before the downgrade.
You can use the cfgSize command to check both the maximum available size and the currently saved
size on all switches. Refer to the Fabric OS Command Reference Manual for details on the cfgSize
command. If you believe you are approaching the maximum, you can save a partially completed Zoning
configuration and use the cfgSize command to determine the remaining space.
For important considerations for managing Zoning in a fabric, and more details about the maximum zone
database size for each version of the Fabric OS, refer to ”Maintaining zone objects” on page 387.
To create a Zoning configuration
1. Connect to the switch and log in as admin.
2. Enter the cfgCreate command.
3. Enter the cfgSave command to save the change to the defined configuration.

You are about to save the Defined Zoning configuration. This
action will only save the changes on the Defined configuration.
Any changes made on the Effective configuration will not
take effect until it is re-enabled.
