The device files //dev/sda and sdb represent your raw drives. sda1 and
sda2 are partitions that the kernel thinks it sees on sda. I'm not
sure how partitions work on your bios-raid system, but I don't think
they are really meaningful.

The peice of the puzzle that you seem to be missing is that dmraid
will create  new device files to represent the raid volume (and any
partitions on that volume). The dmraid device file(s) should be
/dev/mapper/<something>, where the <something> is a long-ish string
that depends on the type of bios raid and some other factors.

Just look in /dev/mapper/ after running dmraid, and you should see the
files there. See the following howto from the ubuntu forums:
