Red Hat RAID Problem

Hi there guys

I'm fairly new to Linux, and I have a problem which I'm hoping you guys can help me with.

We are installing Red Hat 7.2 on HP DL380G3 dual processor servers for our upcoming SAP system. We are not using the on-board 5i RAID controller, but have plugged in a new HP 6400 RAID controller which will control two logical drives (6 physical). Initially Anaconda couldn't see the drives at all, so I managed to download an Anaconda update disk image and a 6400 driver disk image from HP, and we were then able to install with the default kernel. Was able to boot into KDE fine.

Next I needed to upgrade the kernel to 2.4.9-31enterprise (as required by SAP). This was easily accomplished using RPMs for both kernel and source. Since I am running GRUB as the bootloader, I have a neat menu for booting into the different kernels. Problem is, I get a "kernel panic: no initrd" when booting into the new kernel. I am assuming that this is because the new kernel is not loading the driver for the RAID controller, thus Linux cannot even see the disks for booting purposes. My question is, how do I load that driver module for the RAID controller, so that Linux can boot? The module file name is cciss.o.

I am hoping that loading modules during boot is a fairly elementary thing using GRUB. Any help would be greatly appreciated!

Did you "mkinitrd" after you upgraded your kernel?
if not give that a shot...
