Database Merge Guidelines
To display device alias information in zone sets, use the
show zoneset
command (see
Example 24-4
and
Example 24-5
).
Example 24-4 Displays the Device Aliases in the Zone Set Information
switch#
show zoneset
zoneset name s1 vsan 1
zone name z1 vsan 1
pwwn 21:01:00:e0:8b:2e:80:93 [x] <---------------
Device alias displayed for each pWWN.
pwwn 21:00:00:20:37:39:ab:5f [y]
zone name z2 vsan 1
pwwn 21:00:00:e0:8b:0b:66:56 [SampleName]
pwwn 21:00:00:20:37:39:ac:0d [z]
Example 24-5 Displays the Device Aliases in the Active Zone Set
switch#
show
zoneset active
zoneset name s1 vsan 1
zone name z1 vsan 1
* fcid 0x670100 [pwwn 21:01:00:e0:8b:2e:80:93] [x]
pwwn 21:00:00:20:37:39:ab:5f [y]
zone name z2 vsan 1
* fcid 0x670200 [pwwn 21:00:00:e0:8b:0b:66:56] [SampleName]
pwwn 21:00:00:20:37:39:ac:0d [z]
Device Alias Statistics Cleanup
Use the
clear device-name statistics
command to clear device alias statistics (for debugging purposes):
switch#
clear device-alias statistics
Database Merge Guidelines
Refer to the
“CFS Merge Support” section on page 6-8
for detailed concepts.
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 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.
Device Alias Configuration Verification
You can view device alias information by using the
show device-alias
command. See Examples
24-6
to
24-17
.
