This was added to a SOLVED thread... I'm trying a new post to see if it gets any more of a response:
I plan to use VOL MOVE to evacuate all volumes from an aggregate that resides on a shelf in need of replacement. However, as luck would have it, one of the disks belongs to a root aggregate. Are there any special concerns with running the "storage disk replace" command against a disk that is part of a root aggr?
