Merge Failure Issues Chapter 15 Troubleshooting Distributed Device Alias Services Send documentation comments to [email protected] Resolving a Validation Failure If the device alias databases can be merged without any conflicts, the resultant device alias database is validated with the registered applications on each switch in both fabrics being merged. If an application fails the validation of the merged database for any reason, the device alias merge fails. To verify that the device alias database merge is failing because of an application validation failure, follow these steps: Step 1 Step 2 Step 3 Review the CFS or device alias merge failure syslogs to confirm that the merge failed, or issue the show cfs merge status name device-alias command to view the status of the merge. Verify that the reason for the merge failure is an application validation failure by using the show device-alias merge status command. switch-1# show device-alias merge status Result: Failure Reason: This is a non device-alias error. Examine syslog messages. The syslog for the switch where the validation is rejected and the syslog for the switch managing the merge show relevant error messages. Example 15-6 shows a sample message on the switch where the validation is rejected. Example 15-6 Validation Rejection Syslog Message 2007 Apr 10 00:00:06 switch-2 %DEVICE-ALIAS-3-MERGE_VALIDATION_REJECTED: Failed SAP: 110 Reason: inter-VSAN zone member cannot be in more than one VSAN Expln: Example 15-7 shows the syslog message on the switch managing the merge for the same merge failure. Step 4 Example 15-7 Validation Failure Syslog Message 2007 Apr 9 16:41:22 switch-1 %DEVICE-ALIAS-3-MERGE_VALIDATION_FAILED: Failed SWWN: 20:00:00:0d:ec:04:99:40 Failed SAP: 110 Reason: inter-VSAN zone member cannot be in more than one VSAN Expln: Examine the output of the show device-alias internal validation-info command, issued from the switch managing the merge. In this example, SAP 110 on switch 20:00:00:0d:ec:04:99:40 (switch-2) rejected the validation. The status message shows the reason for the failure, along with the system application (SAP) number. switch-1# show device-alias internal validation-info Validation timer: 0s Per SAP Info Table SAPS: 0 MTS Buffer Array Details Buffers: 0 Local Status Num Reqs Sent: Num SAPs Done: Failed SAP : 0 20:00:00:0d:ec:04:99:40 0 0 Status: success Expln: 15-8 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05

Chapter 15
Troubleshooting Distributed Device Alias Services
Merge Failure Issues
Resolving a Validation Failure
If the device alias databases can be merged without any conflicts, the resultant device alias database is
validated with the registered applications on each switch in both fabrics being merged. If an application
fails the validation of the merged database for any reason, the device alias merge fails.
To verify that the device alias database merge is failing because of an application validation failure,
follow these steps:
Step 1
Review the CFS or device alias merge failure syslogs to confirm that the merge failed, or issue the
show
cfs merge status name device-alias
command to view the status of the merge.
Step 2
Verify that the reason for the merge failure is an application validation failure by using the
show
device-alias merge status
command.
switch-1#
show device-alias merge status
Result: Failure
Reason: This is a non device-alias error.
Step 3
Examine syslog messages. The syslog for the switch where the validation is rejected and the syslog for
the switch managing the merge show relevant error messages.
Example 15-6
shows a sample message on the switch where the validation is rejected.
Example 15-6

Example 15-7
shows the syslog message on the switch managing the merge for the same merge failure.

Step 4
Examine the output of the
show device-alias internal validation-info
command, issued from the switch
managing the merge. In this example, SAP 110 on switch 20:00:00:0d:ec:04:99:40 (switch-2) rejected
the validation. The status message shows the reason for the failure, along with the system application
(SAP) number.
