After not using Fortimanger enough to justify the costs I've taken in out of the Fabric. So far so good.
All FG's accepted this as it came down from the Fabric. However one failover FG now has a sync problem. After investigating this I've found that it still thinks it has central management. While the Active FG does not.
In order to clean this up I tried to unset the central-management on the failover FG. This is where I run into a bug/issue. I can't seem to unregister the FM. I'm getting the following error:
Please unregister-device from FortiManager first. object set operator error, -582 discard the setting Command fail. Return code -582
