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.
