4. Issue either the cfgSave, cfgEnable, or cfgDisable command to commit the change and distribute it to the fabric. The change will not be committed and distributed across the fabric if you do not issue one of these commands. Viewing the current default zone access mode To view the current default zone access mode: 1. Connect to the switch and log in as admin. 2. Issue the defZone --show command. NOTE: If you performed a firmware download of an older release, 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. See the Fabric OS Command Reference for additional information on the defZone command. Zone database size and zone merging Merging zones Table 57 presents zoning database size limitations for various Fabric OS release versions. 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. Table 57 Zoning database limitations Fabric OS version Maximum database size (KB) 2.4.0 64 2.5.0 64 2.6.0 96 3.0.0 128 3.1.0 96 3.2.0 256 4.0.0, 4.1.0, 4.2.0 128 4.4.0 256 5.0.1 256 5.1.0 256 5.2.0 or later 1024 (see the following note for restrictions) Before linking two switches together, it is important that you know the zone database limit of adjacent switches. For example, when switches running Fabric OS 3.2, 4.4.0, or 5.1.0 discover that the zone merge database is larger than its pre-determined zone database size limit, they issue a reject notification before symmetrically segmenting their own ends of the ISL, thereby preventing the new switch from joining the fabric. NOTE: Fabric OS 5.2.0 and later support a zoning database size of 1 MB. To support a 1 MB zoning database, the entire fabric must be upgraded to 5.2.0 or later. If any pre-5.2.0 switches are part of the fabric, the maximum zone database size is 256 KB. If the zoning database size exceeds 256 KB, switches not upgraded to Fabric OS 5.2.0 or later are segmented out of the fabric. Use the cfgSize command to display the zoning database size.
