Which could these be?
If you're using software RAID, the boot device will now be "/dev/md?". You will need to configure your boot loader (grub or LILO) to boot from that partition, make sure your initrd loads all of the right modules, and change your /etc/fstab to mount the md devices instead of the hard drive devices. I have found this to be surprisingly tricky to get right on the first try, so make sure you have a boot disk handy. Creating a configuration file for the RAID devices seemed to help mkinitrd/yaird figure out that it needed the RAID modules. grub seemed to have better support for RAID than lilo, although it was a bit "magical" and hard to debug when it didn't work properly. At one point I found some useful instructions with google, but I can't seem to find them now. Still, there seem to be some useful howto guides that should get you pointed in the right direction.
