We have an issue occuring in a HA cluster, the HA connection goes down, so a passive device transit to the active state and thene backword to passive due to a split brain recovery procedure (is it because of the heart-beat backup configured ?) and a second after all network interfaces goes up/down. Is this a normal behaviour?
We are running PAN-OS 4.0.5.
Which HA connection went down, HA1 or HA2? Also, did you enable heartbeat backup on both PA devices?
Preemption Hold Time
Enter the time a passive or active-secondary device will wait before taking over as the active or active-primary device (range 0-60000 ms, default 0 ms).
Promotion Hold Time
I have experienced this issue on lower PANOS 4.0.x that makes fail-over and occurred HA split brain issue. It was occurred also when HA backup link configured phsycally and HA backup option configured.
I finally cleared this issue after upgrade PANOS 4.0.6 I guess this is critical issue on lower PANOS 4.0.x and suggest to upgrade PANOS higher version on 4.0.x.
