Zoning configuration management 11 4. Enter the cfgShow command to verify the renamed zone object is present. 5. If you want the change preserved when the switch reboots, enter the cfgSave command to save it to nonvolatile (flash) memory. 6. Enter the cfgEnable command for the appropriate zone configuration to make the change effective. Zoning configuration management You can add, delete, or remove individual elements in an existing zone configuration to create an appropriate configuration for your SAN environment. After the changes have been made, save the configuration to ensure the configuration is permanently saved in the switch and that the configuration is replicated throughout the fabric. The switch configuration file can also be uploaded to the host for archiving and it can be downloaded from the host to a switch in the fabric. See "Configuration file backup" on page 178, "Configuration file restoration" on page 180, or the configUpload and configDownload commands in the Fabric OS Command Reference for additional information on uploading and downloading the configuration file. New switch or fabric additions When a new switch is added to the fabric, it automatically takes on the zone configuration information from the fabric. You can verify the zoning configuration on the switch using the procedure described in "Viewing the configuration in the effective zone database" on page 258. If you are adding a switch that is already configured for zoning, clear the zone configuration on that switch before connecting it to the zoned fabric. See "Clearing all zone configurations" on page 258 for instructions. Adding a new fabric that has no zone configuration information to an existing fabric is very similar to adding a new switch. All switches in the new fabric inherit the zoning configuration data. If a zone configuration is in effect, then the same configuration becomes the enabled configuration. Before the new fabric can merge successfully, it must pass the following criteria: • Before merging zones To facilitate merging, check the following before merging switches or fabrics: - Zoning licenses: All switches running Fabric OS v6.0.x or earlier must have a Zoning license enabled. - Native operating mode: All switches must be in the native operating mode. - Default Zone: The switch being merged into the existing fabric should be configured with the same default zone mode as the existing switches. • Merging and segmentation The fabric is checked for segmentation during power-up or when a switch is disabled or enabled, or when a new switch is added.
