I have a Dell XPSM1730 laptop with raid 0 configured on with the two drives. This is working fine for the vista install that is on the machine, however when I boot to the hardy live cd, install dmraid and issue the command I get an error for each drive and it says there is no raid present.
I've done some digging and one article mentioned that dmraid relies on AHCI, after checking my bios, it's a bit cryptic about if that is enabled when raid is enabled...
ubuntu@ubuntu:~$ sudo dmraid -ay
ERROR: isw: Error finding disk table slot for /dev/sdb
ERROR: isw: Error finding disk table slot for /dev/sda
No RAID disks
Can anyone point me in the right direction to get the raid array visible to ubuntu?
