Migrating from IDE to LSI Logic SCSI RAID -- how?

I am upgrading RedHat 9 from an IDE HD to a LSI Logic MegaRAID SCSI 320-1 controller.

I have done the following:

1) Copied my two partitions using bootit-ng:
hda1 ext3
hda2 swap

sda1 ext3
sda2 swap

2) Changed my fstab so that the swap partition is correctly /dev/sda2 instead of /dev/hda2

3) Run linux rescue in order to run grub-install to place grub on /dev/sda MBR during which I have to install the driver for the LSI controller.

This is where I am:

The grub menu comes up ok and I begin booting. However, right after the IDE channels are scanned, I get:

VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" option
kernel panic: VFS: Unable to mount root fs on 00:00

I do not believe that the drivers have been loaded into the linux installation for one. I also understand that I need to rebuild my initrd?

Anyone know what the next step is?

I dunno. I have done this before except mine was in /dev/rd/c0d0p1 not /dev/sda1 and all I did was change the bootloader, fstab and then booted with floppy tro the raid, ran lilo (i use lilo) to install the botoloader on the raid and rebooted and it worked. I never had to rebuild anything.

Very weird
