PA HA timers : Preemption Hold Time vs Promotion Hold Time

[gpsriram]

Hi!

What are the difference between in the Preemption Hold time and Promotion Hold time?

Hi @gpsriram ,

From the help pages :

Promotion Hold Time—Enter the time that the passive peer (in active/passive mode) or the active-secondary peer (in active/active mode) will wait before taking over as the active or active-primary peer after communications with the HA peer have been lost. This hold time will begin only after the peer failure declaration has been made.

Preemption Hold Time—Enter the time in minutes that a passive or active-secondary peer waits before taking over as the active or active-primary peer (range is 1–60; default is 1).

Promotion happens when a peer fails ... preemption kicks in when the primary member becomes active again.

I hope this clarifies things.

Cheers !
