If the hardware has no means of identifying the disks (e.g. an
indicator LED) then you could for example do a SMART query to find
the serial number and physically label each disk with that.  Then
even if one dies to the extent that it won't respond to SMART, you
can tell which it is without pulling disks out because you will know
what all the *other* ones are.

Bear in mind that the same physical disk can end up with a different
device node (/dev/sdX) under various circumstances, so it isn't
always that useful to say "this disk is /dev/sdf").
