How to move disks between controllers on a NetApp HA Pair

How to move or reassign a disks from one controller to another on a NetApp

Disclaimer: I take no responsibility if you screw up, or otherwise render your system unusable.  That being said, if you aren't a moron, this works every time.

1. Don't be an idiot, make sure your disks aren't in use first.  They will be spares.  If you execute this command and they don't show up in the list, make sure they aren't: 1) in use, 2) broken, or 3) on the other controller

NETAPP-A> aggr status -s

spare           1d.21.0

spare           1d.23.0

spare           1d.23.1

2. Go to advanced mode

NETAPP-A> priv set advanced

3. Remove ownership

NETAPP-A> disk remove_ownership 1d.21.0

NETAPP-A> disk remove_ownership 1d.23.0

NETAPP-A> disk remove_ownership 1d.23.1

4. Go to the other controller and grab them

NETAPP-B> disk assign all

5. Verify they are on the new controller

NETAPP-B> aggr status -s

spare           1a.23.0         (not zeroed)

spare           1a.23.1         (not zeroed)

spare           1d.23.1         (not zeroed)

6. Zero them as spares to save yourself time

NETAPP-B> disk zero spares

7. Go back to the first controller and get out of advanced move

NETAPP-A> priv set

8. That's all folks!
