Upgrade Process for Master - Local set up question

My organization has a very large Master-Local setup configuration at multiple sites across the country. We currently have one Master Controller that only does just that, and 50+ local controllers at sites, some of which are local controllers with a standby backup in VRRP. 

I want to upgrade to the latest 6.4.2.13 image, but I am confused a bit about the process to upgrade. 
- If I were to upgrade the Master Controller first and reboot, will that cause an outage for all local controllers or will they remain online? 
- If the Master Controller comes back online with the newest software image, will it still be able to talk to the local controllers that are on a previous image until I can get them all upgraded, or do they lose connectivity to the Master until they are on the same image?

- Does the Master push out the software to the local controllers, or do I have to manually install it on each local controller?

 

One last side question. In the Release Notes for 6.4.2.13, it says that older 3200 series controllers do not support the 6.4.X AOS, but we actually have two 3200 series controlles running 6.4.2.6 image...is that wrong for us to be running that version on them, or can they in fact support the newest software?

 

Thank you. 

Re: Upgrade Process for Master - Local set up question

If the master on a different code you will not be able to make changes to your locals
If you upgrade your master first your locals will still function but you will not be able to do the following :
ARM Calculations (No channel and power adjustments)
Push new configs
Thank you

Re: Upgrade Process for Master - Local set up question

If you have airwave you can utilize it to rollout the code upgrade based on a group of controllers
Thank you

Re: Upgrade Process for Master - Local set up question

vfabien is correct:

 

If a local cluster has a different administrative domain (other people managing them who are different that the people who manage the master), or you need to upgrade more aggressively than the master, you should consider making that local cluster a master/local cluster of its own....  That would separate that site administratively from the master and give you more flexibility.

 

You have the option of using Airwave to manage the configuration of master controllers centrally, so that multiple master share the same configuration.  The Airwave document on how to configure Aruba controllers is here:  https://support.arubanetworks.com/Documentation/tabid/77/DMXModule/512/Command/Core_Download/Default.aspx?EntryId=14107

 

Please know that configuring controllers through Airwave has a specific workflow in order for you to be successful, so you should first try it out in the lab, to ensure that you can get adjusted to how this would work within your own system.

We do have Airwave, but we currently have it set for Monitor only, haven't fully deployed its capabilities yet. Maybe someday.

You have the option to do it for as fee or as many sites at a time. It does not have to be all or nothing.

Re: Upgrade Process for Master - Local set up question

Colin, 

 

I guess I am also confused on what the difference between the ArubaOS versions 6.4.X and the Mobility Access Switch version 7.4.X versions? Not in terms of what they fix, but what should I be loading on my 7010 or 7210 controllers? There are different categories for the software but I am not sure what is designed for what we have.

ArubaOS is for WLAN Controllers:  http://www.arubanetworks.com/products/networking/controllers/

 

Mobility Access Switches are Network Switches: http://www.arubanetworks.com/products/networking/switches/

 

You should only be loading ArubaOS on your WLAN controllers.

Okay thanks, yeah I guess I never ran across the MAS, but I think I remember someone once referring to my WLAN controller as a MAS, so that's why i got confused.
