Hi ,
I checked 8.0 documentation, it says cluster deployment scenarios option 1
I understood that we have to define master which is vip , lms and backup lms
Our doubt is what steps we shoul take when putting the other box in network again.
Can we initially make it possible that. Node 1 should take all traffic from APs . Because if it is active active we might end up in network unreachability of some APs
We want some guidelines

"HA" is an older legacy construct from 6.x. If you are running 8.x and clustering, you should not configure the HA parameters. Clustering does everything automatically. Remove the HA configuration, because there should be no active/passive in clustering....everything should be active.

Hi,
We have a customer having high availability issue on Aruba controllers.
Cluster IP: 172.19.11.210
Controller 1: 172.19.11.211
Controller 2: 172.19.11.212
Setup: Active / Passive
Controller Type: Aruba 7205
Controller software: 8.7.1.1_78245
They were configured to initially be in Active – Passive. A power outage brought down the entire wireless network because the controllers werent synced properly ( controller 2 had apprently an old config which was conflicting with the config of the first controller ). Historical reasons not known
Currently the second controller is disconnected from the network to be sure it will not conflict with the working configuration on the first controller.
Only primary is active and everything works .
Now we have to bring the second controller online and make the HA up .I would like to know what steps are needed to get the second controller back into the cluster as a standby node.
We want to make sure that when we make seco dary node online there should be no outage .
Can you guide the steps to be performed .
