Really? I would need to purchase a Netapp disk? the one i purchased is the same brand, size and speed.
i have found the following procedure online .... does this look correct
priv set advanced
disk unfail -s <disk_name>
Repeat above steps for all disks that have failed
Reassign the disks to the storage node
Check disks are added as spares
aggr status -s
All disks should show as spares
disk zero spares
