I thought 'noauto' only was for ignoring the volume upon reboot. What I

want to accomplish is to delete a current volume, e.g. sd2 below.

But I tested anyway, and this is the, perhaps not too surprisingly, result:
# bioctl -i softraid0

Volume  Status               Size Device

softraid0 0 Online           10813440 sd3     RAID1

       0 Online           10813440 0:0.0   noencl

       1 Online           10813440 0:1.0   noencl

softraid0 1 Online           21562368 sd2     RAID0

       1 Online           10781184 1:1.0   noencl

# bioctl -C noauto -c 0 -l /dev/sd0a,/dev/sd1a softraid0
