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).
