Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)
• 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.
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:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Imports the fcalias information for the
specified VSAN.
switch(config)# device-alias import fcalias
vsan vlan-id
Step 2
Device Alias 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.
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.
