This sounds like a grub issue. You will need a way to re-install grub on the
MBR of each disk. You didn't mention if you were using hardware or software
raid. If software, make sure you install the grub boot loader on the mbr of
each disk.

You can boot off SL3 in resuce mode (just type "linux rescue" when booting off
the cd's), which will take you through and try and mount filesystems. You
don't have to mount them, but if you can then it's easy to just use "chroot
/mnt/sysimage" and then "grub something /dev/something" ie. you need to go
through the procedure to install grub on the disk (you can google for the
exact command of this).

If you have a boot disk with grub on it, you can boot off that and go to
command mode (press "c") and install grub onto each disk using:

root (hd0,0)
setup (hd0)

and do the same for the second disk if using software raid.
