Pull one out. :-)
Sorry, couldn't resist, then didn't finish sending. If you
ls -l /sys/block
you should see your disk device names (sda etc) as symlinks to device
paths. The last XXXX:XX:XX.X element before something like ata1 should
correspond to the lspci output (so probably 0000:05:00.0 and
0000:05:01.0). If you know what disks are on what controller that will
answer your question.
cat /sys/block/DEVICENAME/device/wwid
(where DEVICENAME is something like sda) will usually have the serial
number as the last part, which can help identifying disks.
If it's doing hardware raid then there's going to be a more
device-specific answer.
FYI, pulling one out probably won't actually help because they'll
renumber.
