Is it linux software raid or handled by bios on the motherboard? You
can 'cat /proc/mdstat' to see if you have software raid. If you
do, you can 'fdisk -l' the working drive to see the partition size(s),
then fdisk the replacement drive to match, then
mdadm -add /dev/md? /dev/sd?? where the ?'s would be determined
by the array and disk/partition numbers. If it is done at the
bios level it is probably different for each vendor.
