Even though the man page says the above command should work, it
didn't work. I figured out that creating each lun, one at a time
is possible even when using all the disks in the -g option.
I ended up doing this:
foreach i (0 1 2 3 4 5 6 7)
foreach? ./raidutil -c c1t5d0 -l 5 -n $i -s 21543 -g \
10,11,12,13,14,15,20,21,22,23,24
foreach? end
Luca Pizzinato suggests that a "sleep 300" be inserted between
each successive iteration. Mine worked even without the sleep.
