Alternatively, are you sure you have identified your hardware correctly?
According to Supermicro here
the P4SCT has an Intel 6300ESB onboard RAID controller, which according to
is based upon the ICH4, and not Adaptec controller. And, unless I've
missed it, this controller is not supported.
What does dmesg output say about the drives and controller?
