Hardware Mirrored Raid Setup

I was wondering what is the proper way to setup a hardware based mirrored raid.

I have two 2TB drives and a nvidia based raid on the motherboard. I used the nvidia raid manager to setup a Mirrored array consisting of those two drives. The total shows as 1.81TB array.

I boot into OpenSuSe 11.3 and in the partitioner I see two drives (dev/sda and dev/sdb each 1.82TB) listed instead of a single RAID drive.

Am I doing something incorrectly that two drives show up instead of the array? Does something need to be enabled?

It isn't hardware raid; it's fakeraid/firmware raid. Dmraid handles that; usually there's a device in /dev/mapper called something like nvifjcfjfjfjffuf that you treat as the array. Don't touch the underlying disks.
