Probably too late to the party given the rest of the thread, but the plan that Daniel mentioned is the best\easiest: replace the disks with ones that are on the shelf you own.
Here's another way to do it:
If you have to return the shelf, you have to take downtime ANYWAYS (cannot hot-remove shelf from loop)... so just move all the disks from one shelf to the other and give it back to NetApp. Or better even, if the shelf you have to give back has data disks on it, and the shelf you have to keep does not, just give them the other shelf (assuming they are the same).

one by one disk replace. if vol0 were a trad volume with 2 disks you would disk replace the first one to a spare disk on the other aggregate. once complete do the same with the other disk. do this *one by one* for all disks that make up your vol0 volume.

Hi all;
We have a loaner NetApp that has three shelves on it. One of those shelves needs to be returned to the vendor.
An aggregate spans two shelves, one of which is the shelf that needs
to
be returned. This aggregate contains a FlexVol currently in use.
I'd
like to preserve the FlexVol but remove the shelf.
What are my options? Doesn't look like I can shrink an aggregate.
Is
my best bet to shut down everything usin the FlexVol, then vol copy
it
to another aggregate, destroy the original aggregate, remove the
shelf
and then recreate the aggregate again?
Thanks in advance! Ray
Thanks all for the response.
It's only a 512GB (SIS enabled) volume, so I created a new volume on the other aggregate and am using vol copy to copy the data over. This seems incredibly slow (it's estimating two hours to complete) -- I thought it might be a little quicker since there is only about 130GB
of
data on the volume.
Gotta figure out how to up the concurrent login limit on the filer as well, can't even fire up another console to stop the copy if I wanted to! :)
Thanks, Ray
So go the volume all moved. Went well. However, I just realized that vol0 is on aggr0! Argh. Is there any way to relocate vol0 safely while the filer is running?
I guess I could snapshot it, vol copy it to aggr1... what would be the side-effects though?
