​That's the easy part.  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.

​And, how did you manage to do that before Sep 5, 2015?​

Usaly serial number can be read w/o pull disk (for SuperMicro cases

​How?  We have all SuperMicro storage chassis (SC2xx, SC8xx, and JBODs) 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.​  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
