Hi Gene,
Thanks for the reply !! I installed the primary HUB - HA using Secondary hub installer & added the below probes :-
data_engine,ppm probe,nas ,distsrv,sla_engine
after deploying the probes, the data_engine, nas & sla_engine probe shows down.
Also , do we need to deploy wasp probe as well ? since admin console will be down from primary hub & sholud be accessible from Primary Hub-HA ?
