I've made a little script that create the devices:

but I'am still unable to partition anything.
when I do:
# fdisk /dev/rd/c0d0 
I got a "Unable to open /dev/rd/c0d0" !
# ls -al /dev/rd/s0d0 says:
brw-rw---- 1 root disk 48, 0 Jul 31 15:46 /dev/rd/c0d0

I am a bit deconcerted... So if you have any suggestion ?
better script or something that works...


Thanks Pierre.

ps: the bash script...
<bash>
#!/bin/sh
# Script de création des raid devices associés au DAC960
# PBo: 31-07-2003 ###############################

for c in 0 1 2 3 4 5 6 7 
do
	i=0
	for d in 0 1 2 3 4 5 6 7 
	do 
		`mknod "c"$c"d"$d "b" 48 $i`
		i=$(($i + 1))
		for p in 1 2 3 4 5 6 7 
		do 
			`mknod "c"$c"d"$d"p"$p "b" 48 $i`
			i=$(($i + 1))
		done
	done
done

echo "C'est fait..."

</bash>
