So I have a FAS2040 with a single controller running 7 Mode
I'd like to add another and cluster if possible. I have not found any guides in the knowledge base that cover this scenario.
FAS2040 connected via fiber to a DS14 MK2 Shelf
Everything else connects via NFS to the FAS2040.
Is this hot-swapable? Can I just buy a controller and add it in? Do I need to take the entire unit down for this? I've read guides on replacing controllers in a HA pair and that seems easy enough. What about disk ownership after this, will I lose capacity instantly or will I have to play with ownership and set up my cluster as such and assign ownership of disks.
From the looks of other threads the controller needs to be on the same DataOn tap version, thats fine. And a reboot will be needed at some point.
Technically - you can add second controller, it is simple enough. You will need short downtime because both must be rebooted to enable HA. You will also need additional cf license for existing controller. And of course you will need additional hard drives for new controller.
From legal point of view - FAS2040 is end if sale, so there is no way to get it from netapp; and if you buy second hand, license is not transferable. So you really need to discuss it with your NetApp representative.
