I have a client that I am configuring a NetApp system for, but they played around with the system before I got there and have already assigned all of the disks to the aggr0 which is a 32-bit traditional volume.
In light of future upgrade/space concerns/maximization I want to migrate to a 64-bit aggr0 (with vol0 on it) but all of the disks have been assigned (with one free in the pool).
I am not on site so I don't want to do a maintenance restore if at all possible, so my question is since the aggr0 is RAID-DP can I use 'disk fail' to remove two drives and put the aggr0 into a double degraded state, then use the 3 free drives to make my new aggr00/vol00, ndmp copy, change the boot vol and carry on with a normal migration.
If anyone has experience failing disks intentionally to remove them from an aggr so they can be reallocated, please let me know.
