In order to have Sun SPARC system recognize SCSI device with multiple
logical units (e.g. RAID system), you need to :

(1) modify the /kernel/drv/sd.conf. And add LUNs to the target.

        name="sd" class="scsi"
           target=0 lun=0; # target 0 LUN 0, this is default
        name="sd" class="scsi"
           target=0 lun=1; # target 0 LUN 1
        name="sd" class="scsi"
           target=0 lun=2; # target 0 LUN 2
        name="sd" class="scsi"
           target=0 lun=3; # target 0 LUN 3

(2)Then save the file and bring the whole system down and then "boot
-rv". This will reconfigure the system and add the LUNs to proper table.

(3)If you do "format", you should be able to see all logical units --
c0t0d0; c0t0d1; c0t0d2; c0t0d3.
