we have done the "disk replace" method mentioned and it worked without a flaw. it took a few weeks but we actually were able to remove 6 physical shelves with no downtime other than a planned cf takeover->uncable loops of unused shelves->cf giveback.

An aggregate spans two shelves, one of which is the shelf that needs to be returned. This aggregate contains a FlexVol currently in use. I'd like to preserve the FlexVol but remove the shelf.
If you can afford the downtime, you could offline the aggregate concerned, swap the disks into the shelf that can remain, and online the aggregate again. Should be a few minutes.
Another way, which does take a lot longer, is to use "disk replace" to copy the used disks from their old position to their new ones. No downtime, but the disks get copied one at a time, which can be a few hours.
