I don't know about this. I added a 3Ware controller to my pre-existing
RHL9 system, created the appropriate partitions, formatted them, moved the
data to them that I wanted to store on them, and then made sure that I
added those partitions to the fstab, myself.

Without seeing his fdisk -l output, it's hard to say what he has to do,
but, assuming from what he wrote, that the RAID disk shows up as /dev/sda,
his system is already seeing the disk/device, as his swap partitions are
both on that device and mounted.

All he probably really needs to do is remember that the paritioning
programs are not necessarily going to modify his fstab file, and that
he'll need to know what partitions he wants to mount, where he wants to
mount them, and to modify his fstab file, accordingly.
