I don't believe this is an official supported procedure.  There are reports that it has worked, but there are others that
it has caused crashes.  I would wait until you can take a quick downtime before doing this.

Subject: removing a loop from running filer


I have not done this recently so I was hoping someone on the list has.  Basically I need to decomission a loop on an existing filer and migrate the shelves to another filer.  I need to do this with the original filer live and running no downtime can be incurred.

the aggregate has been destroyed
the disks were all zeroed and are now spares
i have verified each individual disk resides in the shelfs/loop i need to remove and no data/root disks are in this loop

cluster failover will be disabled during this procedure.

at this point i should be able to remove the optical loop cabling and the filer will complain but otherwise keep on running correct?

thanks for any input in advance
