I was unable to get disklabel to find my new drive. Turns out the problem was
hardware related - the SCSI jumpers weren't installed correctly which resulted
in SCSI id 8. After fixing this to SCSI id 4 things went much more smoothly. The
key piece of information I lacked was how to determine the rz## number. Here's
the answer from Alan Davis (based on the >>> show device command at the boot
prompt).
Here's the short course in console -> DU device names :
DKB400
DK == scsi disk
B = bus where a=0, b=1, etc
4 = target on bus (SCSI id number)
0 = always 0 (for now)
0 = LUN where LUN 0 = a, 1 = b, etc and is now only seen with hsz
controllers
for non-hsz ignore
the formula for device naming is :
rz + LUN + (8 * bus) + target
rz + ignore + (8 * 1) + 4
rz 8 + 4 = rz12
Another gem comes from George Guethlein is how to use disklabel for a 3rd party
drive
# disklabel -rw rz12 rzxx
where the rzxx tells the command to get the disk physical information from the
disk itself.
