Sil 3112 RAID1 Help

[negrox]

I'm using an Asus a7n8x motherboard. I have connected 2 identical Maxtor SATA disks to the onboard Sil 3112 SATA RAID controller. The disks are seen by the system but I am having a problem configuring the RAID1.

dmesg output:

echo "0 240121728 mirror core 1 128 2 /dev/sda 0 /dev/sdb 0" | dmsetup create raid.devmap

Another member on the forum wrote a how to and he used the above command. It's not working for me.

My question is how can I setup a RAID1 array using dmsetup/dmraid? I have installed dmraid and device-mapper. I can't find much documentation on the issue.

Thanks!

I do not now dmsetup/dmraid, but I set up raid O with mkraid.
There is a how to somewhere in the forum.
