*THIS IS NOT SUPPORTED*

I have in the past removed shelves from 7-mode and cDOT systems

There was no intent to put them back on the same controller.

I had no issues, but that does not mean you won't.

As removing shelves from a 7-mode system generally result in the possibility of an unstable system, it is a good idea to reboot shortly after.

Or better yet, schedule a reboot and remove the shelves at that time.

A Shelf of disks that are not active does not generate very much heat. Only when they are active will the BTUs increase.

David,
Depending on the configuration and OS you can hot remove shelves:

Good luck.

Hi,
We are migrating all data from an old fas2040 to a newer netapp
in a different location. The fas2040 has several DS14 shelves, and one ds4243 shelf.

I wonder if I can just turn off disk shelves as the data is migrated?
Normally I'd just let the disks spin till I had everything safely moved, and
the disk sanitized. But we lost AC in this room, and warm weather approaches.
Can I simply unshare, and unmount all volumes on a disk tray, then turn
the tray off to reduce heat generation?
(later once I know all the data is safe, and snapshots have caught up
on the new system, I'd like to turn the shelf back on, delete the aggregates,
and sanitize the disks)

Will this work? Or will the 2040 be very unhappy if a shelf is turned off?

Thanks for your help
David
