Master failure in master-local setup

Hi,

 

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?

Re: Master failure in master-local setup

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.
