At the /Proc/scsi directory I have the following;
aic7xxx, mptscsih, sg.  Are any of these the type of RAID devices installed?

I have another DELL server, which I have loaded RH3 and its GNOME Hardware Browser shows the RAID devices, yet the same OS on the HP does not show the RAID devices.  Question, why does one show it and the other does not?

The hardware within a Dell system has additional functionality that allows the reporting of RAID (I'm guessing that it's a PERC RAID CARD. It is possible that this uses the same driver as the HP RAID device as many RAID cards have identical chipsets.

You will find that cheaper systems will normally have less functionality, so I can easily imagine a situation where one card has the bare minimum functionality, and another has bells and whistles as well.

Minis and Jaguars are both cars. Both have 4 wheels and an engine and steering wheel, but the Jaguar may have electric windows/air conditioning etc.
