I don't know this controller, but I have seen a few lately that in the
firmware/BIOS for the controller you would configure each drive as a RAID 0
SINGLE. Then they show up as a /dev node the way you'd expect.
I wasn't used to this, as I was still used to just being able to configure
the controller for JBOD and that was that.
