I want to remove a disk shelf from a HA pair and connect that disk shelf into an another HA pair.
Hope someone will correct if my steps below are wrong..
1- Destroy the aggregate (I snapmirrored all volumes to an another aggregate which is not part of this disk shelf and moved the root volume too).
2- cf disable.
3- disk zero all
4.disk asign <disk id> -s onowned on eat a time for all the disks on that shelf.
5- halt both controllers.
7. power down the shelf and remove it
I am not sure whether I have to power down the controllers.
You do not need to power down controllers, but you need halt both of them.
1- Destroy the aggregate
2- Unown the disks
3- Zero the Spares
you may hit "Failed DISK/Bad Labelled disk" problem when you connect this shelf. Pls refer this link for that https://communities.netapp.com/thread/10933
