Active-Passive HA failover and Preempt disabled

L1 Bithead

I have an active passive pair:

 

PAN01- Passive , device priority 50, Preempt- disabled

PAN02- Active, device priority 40, Preempt- disabled

 

Now I wanted to switch the priority i.e. to make PAN01 active and PAN02 passive.

 

I changed the priority on PAN02 to 60 and committed configuration, but it remained active and PAN01 remained passive.

 

I had to suspend PAN02 and make it functional back, to achieve my goal. Then only PAN01 became active and PAN02 became passive.

 

Isn't it supposed to change modes as soon as I change priority and commit? Or does this behavior has anything to do with preempt being disabled.

the device priority is only used when preempt is enabled

with preempt disabled the first device to boot up becomes active, afterward you need to manually fail over to make the other member active
