Can disksuite mirror a raw partition ?

I don't actually do it, because I've normally used
veritas volume manager for database applications that
use raw devices, such as informix for example.
So, say you create m50 which is a mirror of two other
devices, m51 and m52 you would do:
metainit d51 1 1 c0t0d0s4
metainit d52 1 1 c2t0d0s4
Then you would setup the mirror as:
metainit d50 -m d51
At this point, you have a 1 way mirror, so add in d52
metattach d50 d52
In order to use the raw device, just refer to
/dev/md/rdsk/m50
in the same way as you would if you were using a non-mirrored raw device - in the example above you would originally have used /dev/rdsk/c0t0d0s4.
Hope this helps.
