as a starting point ...
for each disk use disklabel to create 2 partitions (or type RAID)
(using f and g)

riad0.conf would be
start array
1 2 0
start disks
/dev/wd0f
/dev/wd1f
start layout
32 1 1 1

riad1.conf would be
start array
1 2 0
start disks
/dev/wd2f
/dev/wd3f
start layout
32 1 1 1

and riad2.conf would be
start array
1 4 0
start disks
/dev/wd0g
/dev/wd1g
/dev/wd2g
/dev/wd3g
start layout
32 1 1 5

disklabel up raid0 and raid1 with 1 partition each - h and the

raid3.conf would be
start array
1 2 0
start disks
/dev/raid0h
/dev/raid1h
start layout
32 1 1 0

Note the above is a starting point that should give you one raid 5 on
dec raid2 and a raid 10 on raid3

hope that helps
