Hi Jeff,
it's unsupported, but with some precautions you could minimize the
risks of panic:
- evacuate (provided you have enough spares) the shelf using
- disk replace start[-f] [-m] <disk_name>
<spare_disk_name>
- check that all (relevant) disks have 2 paths
- -> none of the disks should be in use now, all should be
spares
- you could now: disk remove <disk_name>
- spins them down and let's ONTAP know you're about to remove
them...
- bypass the shelf on the one path (e.g. the upper ESH)
- wait a few minutes (~5) to stabilize the ONTAP MP-config
- don't know if that is necessary, but better safe than
sorry...
- bypass the shelf on the other path (e.g. the lower ESH)
Of course if you have SyncMirror, it's a lot easier, but even
there you should offline the affected plex(es), just to be nice...
(e.g. aggr offline MyAggr/plex03)
Hope that helps, tell us how it went...

Greetings,
Is there a way to remove DS14 MK4 shelves from a running cluster? I
need to look into isolating some drives and removing some shelves and
would like to do it without having to halt the cluster. This is a
7.3.5.1 Ontap cluster on FAS6080s.
Thanks,
Jeff
