This is on the bare hardware, that you installed RHEL correct? The reason I ask that is because this hardware platform is generally known as a virtualization platform. But it sounds like you are seeing a single 'logical' drive. This server-class hardware should have a raid/drive controller presenting the logical disk to the OS.
I would check your POST for options to configure a Raid/Disk controller. It might be defaulting to a mirrored set; which would only present the OS with a single logical drive. That is the first thing I would check at least. Also, why aren't you installing on RHEL6?

Redhat version is 5.7. Both systems have two scsi hard drives, however I can only see one drive. Is there a command similiar to "format" from the Solaris world that will list out all available disk drives? If I use fdisk -l, I only see sda1 and sda2 which is the drive that Redhat was installed to. I don't see anything listed in /dev similiar to sdb or hdb which is the way I understand it to work. I am in the process of learning Redhat after a long background with Solaris.
