The ability of recent versions of smartctl to examine disks behind
PERC controllers is nice, but there's a nasty bug with it: if you have
multiple PERC/MegaRAID/LSI controllers in the system, smartctl always
looks at the first PERC device in the system, no matter what device
you give it.

E.g.:

$ smartctl -i -d megaraid,0 /dev/sda | grep Serial
Serial number: 3JR4LK23M

$ smartctl -i -d megaraid,0 /dev/sdb | grep Serial
Serial number: 3JR4LK23M

This has been a known problem for 9 months:

Unfortunately, the smartctl documentation doesn't mention this bug at
all.
