I've figured out what's wrong with our Ruckus install.
The controller CPU is maxed out most of the day.
So I've got a brand new fast machine here, and I've installed the same vSZ version on it.
I saved the config from the old vSZ, and uploaded it to the new one... Looks OK.
I've hit a brick wall on how to license it.
I tried to remove the existing controller's license on the Ruckus portal. But couldn't get the new one to register. I had to reallocate the license to the old controller. Both ended up on 1 AP, but I got the old one re-registered OK with 60 APs.
The other trouble I have is the new controller reports it's *** Cluster Out of Service *** even after an hour.. Which means it won't accept a license file.
I would've just moved the VM but it's disk is 100GB and I don't want the wifi down for that long.
I think I'm going to need a hand with this one.
