If you're on SATA: sdparm --all /dev/sdb
(supposing you have the sdparm package)
and you'll find all informations about the disk (Model/Serialno). The one 
you're looking for is of course the Serial number, the same that is on the 
disk.

But if you have racked drives, you'll can't read the label it without stopping 
the system... that's why that's important to know the hardware port sequence 
of your controller.
