doing some testing with clearpass cluster (version 6.3) and had a subscriber down for over 1 day. in the logging i noticed it went to status disabled after some time. now i started the subscriber again and was wondering if i can get it in the cluster without a drop / rejoin. checked the GUI, CLI and manual but can't find a hint.
the whole idea of node disabled status makes me believe i can enable it somehow, is that true or is drop and rejoin the only thing to do?
When subscriber (configured as Designated Standby) went out of sync, you may have noticed that Publisher marks the node as disabled / cluster sync status is disabled.
In such a situation, please use the below steps:
1. On a subscriber node (configured as Designated Standby), if needed take a logdb backup.
2. Perform a "cluster reset-database" (easily done in CLI)
3. Perform “Make-Subscriber” operation to join back into cluster (using either UI / CLI).
4. After the node is joined as subscriber, check if VIP Service is running on the new subscriber. If stopped, please start the same.
5. This will succeed and High Availability features like VIP and Publisher Standby configurations are restored on this Subscriber node.
Note: In the above steps, you need not drop any of the high availability features before joining the out of sync/disabled Designated standby into cluster. This way, time spent in getting back the out of sync subscriber node (or designated standby) back in action, is much lesser.
thanks Seth, if that the way it is, i will go that route.
hey Seth i tried your stept but it seems to fail, the old subscriber is reset and rejoins but the then it remains out of sync and this increases with every attempt. should it have worked in 6.3?
And this was a lifesaver. As a result of this I managed to rebuild my CPPM cluster after a disastrous atempt at using theweb based upgrade utility
