Last time I checked when I left NetApp in Jan, hot removal was not officially supported even if you destroyed the aggregate and made the disks spares. There was mixed results on whether it worked. Looks like they finally officially documented it in the DS14 shelf guide.

Caution

Hot removal of disk shelves is not supported. Shutdown of filer/FAS appliance is required to remove shelves from system.

 
Try at your own risk and results may vary.
 
It might be worth taking the <1 min downtime to halt the filer, pull the 2 cables quickly and boot up as opposed to taking the chance it might panic, dump core, try and pull the cables fast enough before it reboots....

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
