Device Alias Database Merge Guidelines
Procedure
Step 1
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
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.
For additional information, refer to CFS Merge Support in the System Management Configuration Guide for
your device.
Verifying the Device Alias Configuration
To display device alias information, perform one of the following tasks:
Command
show zoneset [active]
show device-alias database [pending |
pending-diffs]
show device-alias {pwwn pwwn-id | name
device-name } [pending]
