• 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
• storage show disk -p
• -> 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
