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:
• Each zone alias has only one member.
• The member type is pWWN.
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:
Database Merge Guidelines
When merging two device alias databases, follow these guidelines:
• 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.
