In worst case scenario, you can reboot the machine and upon boot use key
combination to go into controller BIOS settings, there you should be able
to see which drive failed (Ctrl + H or similar, it will tell you which
keys). I doubt Dell tweaked that away from what LSI has, even though LSI
firmware _is_ tweaked by Dell. You can trust that Dell counts drives from
left to right (wen you look at machine front panel). I don't remember
client utility name that will give you access to this information when
system is running (interface of which is obscure to avoid saying nastier
words, so it is easy to royally screw up in it... that's why I love 3ware
- which has passed away, alas).
