254 Administering advanced zoning
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 for each item name. The number of bytes required for an item name depends on the
specifics of the fabric, but cannot exceed 64 bytes for each 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 version 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. See the Fabric OS Command Reference 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.
