Since you are using HW RAID the tools you mentioned cannot be used to

That is my understanding as well. I just scoured a system with a 3Ware 9550
and tried to get physical device information without using any of the 3ware
tools. I was unable to get ANY information about the actual disks other than
the size of the array/device being reported by the RAID card.
Actually, with 3ware, smartctl *can* see through the adapter to the disks
behind it. E.g. (on a 9650):
[jlb@$HOST jlb]$ sudo smartctl -i -d 3ware,0 /dev/twa0
