Device Alias Configuration Verification

You can view device alias information by using the show device-alias command. See Examples
25-17.
Example 25-6 Displays All Configured Device Aliases from the Effective Database
switch# show device-alias database
device-alias name SampleName pwwn 21:00:00:e0:8b:0b:66:56
device-alias name x pwwn 21:01:00:e0:8b:2e:80:93
Total number of entries = 2
Example 25-7 Displays the Pending Database with No Modifications
switch# show device-alias database pending
There are no pending changes

"CFS Merge Support" section on page 7-9
Verify that two device aliases with different names are not mapped to the same pWWN.
Verify that two different pWWNs are not mapped to the same device aliases
Verify that the combined number of the device aliases in both databases does not exceed 8191 (8K).
For example, if database N has 6000 device aliases and database M has 2192 device aliases, this
merge operation will fail.
