I'm looking to find out what the proper procedure is for resetting a NetApp system to factory defaults. Here's the story:
(First of all, understand I'm new to NetApp systems so have goofed here)
New NetApp FAS3210 HA system, with a single DS4243 shelf (24 x 300GB SAS). From the factory it came with the disks auto-assigned (12 to each controller). As I'm looking to expand this over the next year with more disks (some SAS, some SATA) I made the decision to serve SAS off one controller and SATA off the other. So, I reassigned the spare disks from Controller B to Controller A, and ended up with 21 disks assigned to Controller A (the other 3 hold the default aggregate for Controller B, that's fine for now).
I expanded Aggr0 using System Manager to use all the remaining disks (leaving 1 hotspare). It was at this point that I became educated in Raid Groups, and why not to do this through System Manager. I ended up with an rg0 of 16 disks (the default size) and a second raid group consisting of 4 disks (2 parity, 2 data). This offends me greatly, and as I have learned there is no easy way to undo this action (especially since I made the choice to expand Aggr0 as opposed to creating a new aggregate). Chalk it up to inexperience.
There is no data on this system; I would like to figure out how to restore it to the factory defaults somehow. If that means blowing everything away and reinstalling Data ONTAP, so be it. I just don't know where to look for the procedures.
Hoping there might be a way to back up the Ontap config and restore it afterwards, but that's not critical.
You will need a serial connection to the box (or SP) then reboot the system. Now keep an eye on the reboot it will look something like this ( fas2040 running 18.104.22.168 incase your interested)

Press Ctrl and C together to bring up the special boot Menu at this very moment.
Next you will have 5 potentially dangerous options so be careful.
To factory reset you will select 4a - same as 4 but with flexible volume. This step will take several hours to complete and it will draw ...... to the console.
Once completed you will be taken to the inital setup menu. Any data that was on the other disks assigned to this controller will have to be zeroed with cmd
disk zero spares (again takes a while to complete)
I would then suggest you carry out an upgrade to the ONTAP with the same version as you are currently running, just to make sure the system has built everything correctly. If you upgrade before the zeroing completes you will have to start it off again so I usually upgrade (reboots) then zero.
