I don't know about grub2, but adding the new disks has probably changed
the order of the disks and made your SATA ones the first ones detected,
perhaps. See how they are named when you boot off the network. Another
option is to give the disks a UUID and use the UUID in /etc/fstab.
You will need to put the bookstrap sector onto the SATA disk that comes
first anyway. (Did step 2 do that?) It is probably a good idea to put a
boot sector on all the disks. (again I don't know about grub 2).
