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 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.
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:
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.
switch-1# show device-alias internal validation-info
Validation timer: 0s
