Preempt behaviour in HA

[vishalrsshah]

Hi all,

As per palo alto documentation if we enable preempt in HA then primary palo alto will reclaim its active position if it comes back. Does this reclaim works on complete device failure or for any monitoring link/path failure also.

Hello @vishalrsshah 

The preempt feature only becomes effective when the primary firewall returns to an active state. However, if link or path monitoring fails, the primary firewall will enter to a non-functional state and will not follow the preempt configuration.

So if failed link/path of primary firewall recovers than in that case preempt works ?

No, the preempt feature will not be effective because the firewall will be in a non-functional state due to the link or path failure.
