this is a 0+1 volume (striped and then mirrored). Notice it is made of 2
plexes and the size of the volume is the same as the size of the
constituent plexes. (a mirror can also be mirror of 'concat' instead of
mirror of stripe)

sd Jstor1_1-01  r5minarc-02  Jstor1_1 0        897843200 1/0      c2t0d1

this is a concat. Notice that the size of the volume is the sum of the
sizes of the constituent plexes. Also notice there is only one plex.

A raid volume will clearly say RAID under usetype. They are easy to tell
from everything else.
