High Availability - functions well, however peer device shows offline.

Hello Folks,

 

I have 2 LTM deployed in HA, running over firmware version 11.2.0 However, one of the devices shows offline status in peer list. At the same time the device is in Sync, failover works well too. However in peer list of Primary device, I can see secondary appliance as offline.

 

Anyone had experience similar issues before? What could be the possible and feasible solution?

 

Regards, Darshan

    I ran across this thread while troubleshooting a similar issue, and I thought I would add what corrected the issue on my end. After clustering my 2, 6900s the configurations sync'd but the HA status for the peer device showed down (on both 6900s). After going round and round, I found that my HA self IPs on each device were set for "allow none". I changed them to "allow default" and BAM! Issue fixed.

    from Device management> Device trust>peer List The only time I saw issues with the peer is when the trust was not set up correctly Do you see the Serial number of the peer and its mac address in the Peer list to the right of the pers host name?

    Yes, I tried to even break the trust and re-bond the trust back. However it didn't work though.

    Can we presume that the other way round i.e. from the secondary device's GUI, the status of the primary looks ok? What about if you failover to the secondary, does the old primary (now secondary) appear offline?

      Still does the trick in 12.1.1. Did my lab setup by the book, but this one messed it up. So both units were active, but didn't see eachother. Changed the port lockdown on both ends to 'Allow Default' and BAM! working... Tnx!

    Had the same issuu running 11.4.1. Sync OK, HA OK, but overview stating connectivity problems to one box. Health check did not show anything wrong. After reading this thread I found an interface set to "allow none" after changing that to "allaow default" communication probem message dissapeard.
