Can someone please list out the steps I need to follow to move a set of shelves from one filer to another?
These shelves have aggregates that we want to preserve.
These shelves will be detached form a fas3020 and attached to a fas3060 ina different location.
WHat are the steps?
I am getting conflicting suggestions on if I should do a disk ownership_remove or not.
Hoping someone out there has done this before and can she some light on the correct procedure.
I am not a netapp person so apologies if my questions sound stupid.

the FAS3020 used to use hardware-based disk ownership by default which made moving between controllers much easier. If 'disk show -v' shows you a list of all the disks on your controller, then you're using software-based disk ownership.
These steps would assume that your new destination controller needs to remain up while the shelves are attached. If you are moving to a different ONTAP version, then you should verify compatibility in your environment via the matrix on NOW (ie key things such as Windows iSCSI initiators, NetApp Host Utilities, Snapdrive and Snapmanager products -for starters- will need to be checked).
Basically the steps would involve:
If you're using hardware-based disk ownership, then just type "disk assign all"
If you're running ONTAP 7.3.x then you'll see a stack of 'critical' errors scroll up your screen for each of these disks which you can ignore.
12. Check that all disks are assigned to the correct controller by running: disk show -v
13. You should've seen messages saying that it detected a new aggregate - run this command to see if your aggregate is listed and offline: aggr status -v
14. If all of the correct disks are present for the aggregate, bring the aggregate online by running: aggr online <aggr_name>
15. Check that all vols contained on the aggr are online and then recreate any CIFS shares / NFS exports / LUN mappings from the new controller.
These steps don't include any SAN zoning, persistent binding, DFS updates etc or any host-based reconfiguration if required.
