That's a hardware RAID controller, so it won't (by default) see single
drives and pass them directly to the OS like a normal disk controller
would.  You need to go into the RAID config (you should see an option to
do this at boot) and configure a RAID with a single disk in a RAID0
configuration.

or use the MegaCli from linux to do the same, but the syntax is nasty
