I'm sure I've done this before using linux, but haven't used it in a couple of years now and can't figure it out this round. I have 2 SATA drives connected to my sil3112 raid controller on my motherboard (it's rubbish, i know). I can't get the striped set to recognize in ubuntu 8.04.
I've followed numerous guides and each one ends with something not working quite right.
sudo fdisk -l shows this:

In total there are 4 drives, but I'm only concerned with the top 2 SATA ones that are a RAID stripe set (easily seen within Windows using drivers from my mobo driver disc -- I configured the RAID from the motherboard, it's not a windows set.)
The drives are found, but I can't mount them in anyway. I've installed dmraid and devicemapper already; however, there is not a folder called /dev/mapper/ for me to look at. Also, there is no /dev/sda or /dev/sdb or /dev/sda1 directories.
gianni@server:~$ sudo dmraid -r
/dev/sdb: sil, "sil_ahaedeabajfc", stripe, ok, 625139360 sectors, data@ 0
/dev/sda: sil, "sil_ahaedeabajfc", stripe, ok, 625139360 sectors, data@ 0
gianni@server:~$
Everything appears to be recognized, following guides either has me unable to browse my /dev/mapper dir or unable to properly patch the kernel (ncurses-devel missing).
Could anyone give me a hand with this please?!
*Edit*
More output from dmraid if it helps! It doesn't seem to activate the RAID set. No clue why.
gianni@server:~$ sudo dmraid -an
RAID set "sil_ahaedeabajfc" is not active
