About Legacy Zone Alias Configuration
You can import legacy zone alias configurations to use this feature without losing data if they satisfy the
following restrictions:
•
•
If any name or definition conflict exists, the zone aliases are not imported.
Tip
Ensure that you copy any required zone aliases to the device alias database as required by your
configuration.
When an import operation is complete, the modified alias database is distributed to all other switches in
the physical fabric when you perform the commit operation. If you do not want to distribute the
configuration to other switches in the fabric, you can perform the abort operation and the merge changes
are completely discarded.
Importing a Zone Alias
To import the zone alias for a specific VSAN, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# device-alias import
fcalias vsan vlan-id
Database Merge Guidelines
When merging two device alias databases, follow these guidelines:
•
•
•
For additional information, see the
Cisco Nexus 5000 Series Switch CLI Software Configuration Guide
39-8
Each zone alias has only one member.
The member type is pWWN.
Verify that two device aliases with different names are not mapped to the same pWWN.
Verify that two identical pWWNs are not mapped to two different device aliases.
Verify that the combined number of device aliases in both databases does not exceed 8K (8191
device aliases) in fabrics running Cisco MDS SAN-OS Release 3.0 (x) and earlier, and 20K in
fabrics running Cisco MDS SAN-OS Release 3.1(x) and later.
If the combined number of device entries in both databases exceeds the supported configuration
limit, then the merge will fail. For example, if database N has 6000 device aliases and database M
has 2192 device aliases, and you are running SAN-OS Release 3.0(x) or earlier, then this merge
operation will fail. Merge operations will also fail if there is a device alias mode mismatch.
Purpose
Enters configuration mode.
Imports the fcalias information for the specified
VSAN.
