FMC HA Synch Failed

[mtmharison]

Hi,

After restarting my standby FMC, I have the below message :

 Degraded- Synchronization incomplete
( Database synchronization failed on the local Management Center , Database synchronization failed on the peer Management Center )

Please, how can I resynchronize my FMCs?

Hi, were you able to fix this issue ? If yes, could you please share the fix ?

Under guidance from Cisco TAC we were asked to CLI on to the secondary FMC and run 'manage_HADC.pl' and select option 6 (re-establish' mirror. This took about 10 minutes to complete but seemed to do the trick.

You need to go into secondary FMC or the FMC that have issue. Delete the uuid of the problematic FTD following steps in here How to Delete the Pending Manager in FTD | Blue Network Security.

Then, you can run manage_HADC.pl to reinitiate the sftunnel.

*Do note that this steps is not recommended by TAC as it involving deleting database on the FMC. They suggest to open TAC case to verify the issue and let TAC do this steps. But in case you can take the risk, then you can perform steps above.
