i'm verifying what solutions are available when for example, in a master - local setup, happens if the master dies?
Suppose the master - local setup has centralized licenses.
Could not really find a doc explaining what needs to happen in such a setup to repair the config... I believe :
1. replace controller
2. stage new controller with basic ip connectivity
3. access controller via http, up- or downgrade arubaos software version
4. import and restore flash backup
5. reboot new controller
Would this be sufficiant? Or do i still need to do something regarding the licenses?
Are you using the local to back up the master or for additional capacity?
It's not a master-master setup if you mean this. The local is not really meant for 'additional' capacity. In practice it hosts all our ap's. That way a device can roam between different ap's without the need to implement something special. The master is in that case a failover controller.
If the local is only to backup the full capacity of the master, you should configure master redundancy and make the local a backup master instead. If anything happens to the master in that configuration, the backup master will become the master and will also become the centralized licensing master.
You would have a VRRP between controllers, the master would terminate all APs and handle centralized licensing. If it fails, the backup master would take over all functions seamlessly.
