Hi all
I have a HA group set up on a master-local pair. This morning at around 1am one of the APs decided that the standby (local) controller was its controller. No big deal, it's very possible that it could have lost it's connection to the master. However, there was definitely no known network issues later in the day, I could ping the AP from both master and local fine. But still it held on to the local as its controller. My question is why would this happen and is there a manual way to force the device to use the master instead of the local? I rebooted the AP and this sorted it out but I'd rather not have to do that.
Any thoughts on why it didnt fail back? We have pre-emption in the system profile set at 600s.
Cheers
