Mutual exclusion check failed on peer
Possible Cause
The imported configuration is sent to the peer. However, if the configuration is already configured on
the peer outside of SP, then the import fails the mutual exclusion check on the peer.
Solution
Remove the failed commands from conf-t on the peer and then retry import verify/commit.
Use the show system internal csm info trace command for further investigation to look at events, trace,
or error messages.

Merge Failure

A merge between peers happens when a peer becomes reachable.
A merge is initiated when CFS sends a peer add for the peer or if the peer is already reachable.
Configuring the sync-peer command starts the merge session.
For a merge to succeed, the configuration in the switch-profile on both peers must match exactly.

If the command exists in the global_db, it is possible that there is not enough space in the show run
for the command. Ensure that there are no trailing space/tabs in show running config generation.
If the command does not exist in the global_db, use the show accounting log command to determine
if the command was configured and to display the status of the command.
If the command status was a failure, then the command should not be displayed in show running.
–
If the command is displayed, then the application should correct it.
–
If the command was configured before reload/issu, add the command back. If the accounting log
shows the command's retval as success, determine if the command is getting added to the global-db.
If the command was added correctly, copy r s, check global-db reload, and check if the
–
command exists in the global-db.
If the command does not exist in the global-db, then the issue might be that the command is not

showing up in show running on boot up.
If the command does not exist in the global_db, investigate the csm_save_global_command

function. The csm_save_global_command function is where the command gets added to the
global_db
