Have done that..
# camcontrol devlist -v
scbus0 on isp0 bus 0:
<DGC LUNZ 0531> at scbus0 target 0 lun 0 (pass0)
<> at scbus0 target -1 lun -1 ()
scbus1 on isp1 bus 0:
<DGC LUNZ 0531> at scbus1 target 0 lun 0 (pass1)
<> at scbus1 target -1 lun -1 ()
scbus-1 on xpt0 bus 0:
<> at scbus-1 target -1 lun -1 (xpt0)
also tried
# for i in `jot 255 1 255`
