LinuxQuestions.org - Failed to detect raid set

Hi, I am trying to get gentoo to detect my two raid 0 drives. I am setting up a dual boot and had the disks partitioned. I then installed XP and tried to partition the NTFS partition into three. This messed up the rest so I decided to try again.

I followed the instructions that had worked before, but now when I try again gentoo does not pick up the drives as a raid 0. The instruction I followed shown below ...

Boot from a Gentoo Live CD. Use the kernel option: dodmraid

gentoo dodmraid

Look for devices in /dev/mapper

#ls /dev/mapper
crw-rw---- 1 root root 10, 62 Aug 22 01:35 control
brw------- 1 root root 254, 0 Aug 21 21:46 sil_afaidcaafaci

If you can see only the device called "control", then the Live Kernel failed to detect your raid set, and you can stop reading. If you see another device, than this is your raid set. Lets call it your_raid_set from now on. your_raid_set is the whole "disk" your_raid_set1 is the first partition.

I only get the device called control. I have deleted the raid and recreated it again but that did not help either.

Any Ideas?
