If you have direct knowledge, which serial number is where, you could
use hdparm -I /dev/sdX or smartctl -a /dev/sdX against the still
reachable drives.
Possibly the easiest is to *read* data from the still reachable disks
and check which LED does not blink anymore - if you have LEDs for each
of the drives (dd if=/dev/sdX of=/dev/null).
Otherwise someone needs to look at the "open" hardware to find the
serial numbers.
Does this help?
cheers
Carsten
