Zone database size 11 switch:admin> cfgsave WARNING!!! The changes you are attempting to save will render the Effective configuration and the Defined configuration inconsistent. The inconsistency will result in different Effective Zoning configurations for switches in the fabric if a zone merge or HA failover happens. To avoid inconsistency it is recommended to commit the configurations using the 'cfgenable' command. Do you still want to proceed with saving the Defined zoning configuration only? (yes, y, no, n): [no] y Updating flash ... Viewing the current default zone access mode Use the following procedure to view the current default zone access mode: 1. Connect to the switch and log in using an account with admin permissions. 2. Enter the defZone --show command. NOTE If you perform a firmware download of an older release, then the current default zone access state will appear as it did prior to the download. For example, if the default zoning mode was No Access before the download, it will remain as No Access afterward. Zone database size The maximum size of a zone database is the upper limit for the defined configuration, and it is determined by the amount of flash memory available for storing the defined configuration. Use the cfgSize command to display the zone database size. The supported maximum zone database size is 2 MB for systems running only Brocade DCX, DCX-4S, and DCX 8520 platforms. The presence of any other platform reduces the maximum zone database size to 1MB. Virtual Fabric considerations: If Virtual Fabrics is enabled, the sum of the zone database sizes on all of the logical fabrics must not exceed the maximum size allowed for the chassis (1 MB). The maximum size limit is enforced per-partition, but is not enforced chassis-wide. If the chassis size limit is exceeded, you are not informed of this and unpredictable behavior might occur. It is your responsibility to keep track of the chassis-wide zone database size. ATTENTION In a fabric with some switches running Fabric OS 7.0.0 or later and some switches running Fabric OS versions earlier than 7.0.0, if you execute the cfgSave or cfgEnable command from a pre-7.0.0 switch, a zone database size of 128 KB is enforced. To avoid this problem, use the switch with the highest Fabric OS version to perform zoning tasks, as described in "Best practices for zoning" on page 310. Alternatively make sure that your pre-7.0.0 switches are upgraded with the latest patch release. Fabric OS Administrator's Guide 327 53-1002745-02
