AFAIK there is no official way to do this without downtime.

Subject: Hot remove disk shelves?
We have a FAS3170 HA pair with some SATA disk shelves (AT-FCX) attached to the end of a chain where none of the disks are in use (all are spares, all have ownership assigned). We are running ONTAP 8.0.1.
The chain is singly attached to both controllers, i.e., the shelf "A" modules are chained to a single FC adapter on one controller and the shelf "B" modules are chained to a single FC adapter on the other controller.
The shelves we want to remove are at the far end of the chain.
Essentially we want to undo the result of a hot shelf add without downtime.
Is it possible to hot remove these shelves? Would it help to "un-own" the disks first?
I suppose this could be done using CF takeover/giveback but that might be too disruptive.
