I have a filer which has both SCSI 9G (4 shelves) and FCAL 36Gb (2 shelves). Unfortunately, I was in a rush to add some disk to a volume and added my last SCSI disk to a volume that was all FCAL.
How can I get this disk out of the volume and restore it to hot spare capability? I have 4 space 36G FCAL drives, but it's not enough to do a volcopy and just delete the old volume.
here's the sysconfig -r output for the volume:
RAID group 0

You could raid fail the SCSI drive, go into degraded mode, and rebuild onto a new spare FCAL. It would be risky, though, since there is a small chance of another disk failure during the rebuild process. (Might be a good idea to do a raid scrub first.) You will also take a performance hit during this process, of course.

True, though only 25% of the FCAL disk will be used, and if that disk ever fails and a 9GB disk (SCSI or otherwise) is available, he'll be back to the current situation.
There is no way to shrink a volume, nor to increase the space used on a disk which is a member of a volume. The only way to either remove the 9GB disk from the volume entirely, or replace it with one of the 36GB FCAL disks *and use all of it* is to do a volcopy (or backup to tape, destroy the volume, and restore).

Doh! Since he only mentioned the SCSI vs FCAL issue, I did not even notice that the sizes were different.
Yep, if you want to get the full space back with FCAL, you'll need a small FCAL drive (hah) or copy/restore to a new volume.

Then you'd have to reboot into maintenance mode and restore the disks label.
