Immediate failback
I'm new to v11, and having trouble with the failover process on 11.4.1. I have two members (u1 and u2) in a Sync-Failover group. When I force a failover from u2->u1, u1 reports Active briefly, then it immediately fails back. This process generates the following sequence log entries in /var/log/ltm on u1:
Sep 18 09:07:16 u1 notice sod[6926]: 010c0019:5: Active
Sep 18 09:07:17 u1 err sod[6926]: 010c006a:3: Configuration CRC values disagree amongst peers. Suggest configsync peers.
Sep 18 09:07:17 u1 notice logger: /usr/bin/tmipsecd --tmmcount 4 ==> /usr/bin/bigstart start racoon
Sep 18 09:07:19 u1 notice sod[6926]: 010c004a:5: Leaving active in favor of active peer.
Sep 18 09:07:19 u1 notice sod[6926]: 010c0052:5: Standby for traffic group /Common/traffic-group-1.
Sep 18 09:07:19 u1 notice sod[6926]: 010c0018:5: Standby
This problem started happening after bringing them both up from a graceful shutdown for power maintenance overnight. The only thing that looks slightly "wrong" is the "Next Active Device" property for the (single) traffic group on both units has a status of "Initializing / Not Synced". Seems like it could be related, but I know this was the same status before the power down, when we had no failover issues.
Not being familiar with v11, I'm uncertain where to focus and I haven't found any relevant articles in the KB. Has anyone seen this before?
