Adding Secondary Admin & Secondary MNT node into the cluster issue

[adamscottmaster2013]

I have a three nodes ISE 3.2 patch-2 environment:

ISE1: Primary Admin & Primary MNT,
ISE2: PSN,
ISE3: PSN,

I need to add ISE4 into the cluster and mark it Secondary Admin & Secondary MNT.
However, as soon as I add ISE4 into the cluster, both ISE2 and ISE3 restarted and
caused a 20 minutes outage in my production environment. I am 99% certain that
this was not the case with ISE version 3.1.

Is this expected with ISE 3.2 patch 2?

  - Do you have 'console outputs' from these restarts , if not check show logging system ade/ADE.log , on the involved nodes , however not sure if the older and or needed info is still present after reboot(s) ,

No, that is not expected. Consider calling TAC so they may understand Why this happened.
