Chapter 15 Troubleshooting Distributed Device Alias Services
Initial Troubleshooting Checklist
Note See the “System Messages” section on page 1-10 for more information about using system (syslog)
messages for troubleshooting purposes.
This section also identifies some of the system messages that are issued when device alias problems are
encountered, and it includes the following topics:
• Merge Failure Messages, page 15-2
• Merge Validation Failure Messages, page 15-2
• Commit Failure Messages, page 15-3
• Verifying Device Alias Database Status Using the CLI, page 15-3
• Limitations and Restrictions, page 15-3
Merge Failure Messages
When a device alias merge fails, review the syslog messages on the switch where the merge was issued
(the merge manager). In Example 15-1, the syslog messages indicate that the merge failed as a result of
a database mismatch.
Example 15-1 Merge Failure Syslog Messages
2007 Apr 9 15:52:42 switch-1 %CFS-3-MERGE_FAILED: Merge failed for app
device-alias, local switch wwn 20:00:00:0d:ec:2f:c1:40,ip 172.20.150.38,
remote switch wwn 20:00:00:0d:ec:04:99:40, ip 172.20.150.30
2007 Apr 9 15:52:42 switch-1 %DEVICE-ALIAS-3-MERGE_FAILED: Databases could
not be merged due to mismatch.
Merge Validation Failure Messages
When a device alias database fails validation during the merge process, review the syslog messages on
the switch managing the merge and on the switch where the validation was rejected. In Example 15-2,
the syslog message indicates that the validation failed on switch sWWN 20:00:00:0d:ec:04:99:40.
Example 15-3 shows the syslog message received on the switch that rejected the validation. Both
messages indicate that the merge validation failed because the merge would result in the definition of
the same zone member in multiple VSANs.
Example 15-2 Message on Switch Managing the Merge
2007 Apr 9 16:41:22 switch-1 %DEVICE-ALIAS-3-MERGE_VALIDATION_FAILED: Failed
