Boot with all the drives pulled out a bit, = so they aren't connected/detected. Insert first disk, wait for it to be detected and get a /dev node, then partition/label it. Repeat for each disk. Takes about 5 minutes to label a 45-bay JBOD chassis. No different than how you would get the serial number off each disk before inserting them into the chassis, so you'd know for sure which slot they're in.

We have all SuperMicro storage chassis (SC2xx, SC8xx, and JB= ODs) and server chassis in our data centre here. None of them allow you to read the serial number off the physical disk without pulling the disk out completely.=E2=80=8B You'd have to manually label each bay with the serial= number before inserting the disk into the chassis ... which is no different from labelling the device in the OS. Except it's much faster to find a 3D co-ordinate (enc0a6) than to scan every bay looking for a specific serial number. But, to each their own. :) Everyone has their "perfect" system that works for them. :D --=20 Freddie Cash fjwcash@gmail.com
