"Vunum ld" will list the disks and their status.  If you're not sure
which physical disk is "da1", you'll probably have to look at the
jumper settings on each drive.  Another option is to run something like
"camcontrol stop da1; camcontrol start da1" or "dd if=/dev/da1
of=/dev/null", and see which disk's activity LED lights up.

http://www.vinumvm.org/vinum/replacing-drive.html has some instructions
on swapping out a failed drive.
