You need the drivers mptbase and mptscsi version 2.05.08-1 to be loaded. You can get it from ProLiant Support Pack (PSP) version 7.0.
Version 7.00 of the PSP contains version 2.05.08-1 of these drivers in the Smart Component rpm packages for the ProLiant 64-Bit/133-MHz Dual Channel Ultra320 Adapter.
After loading it, execute:
#mkinitrd /boot/[initrd image name] 'uname -r' -f
Using syntax similar to the following, update the boot loader configuration file:
for GRUB
title (name as displayed in the GRUB boot menu)
root (hd0, 0)
kernel/vmlinuz-[version]roroot=LABEL=/
initrd /[initrd image name used in step 2]
for LILO
image=/boot/vmlinuz-[version]
label=[Name as displayed in the LILO boot menu]
initrd=/boot/[initrd image name used in step 2]
read-only
append="root=LABEL=/"
# after saving, run `lilo`
Reboot the server using the new boot menu option to ensure the correct version of the driver is loaded.

I expect you have the PSP CD. Perhaps the package drivers for DL380 you can get from hp website is also a source for these drivers.
I found something you should be aware: PCI-X Dual Channel Ultra320 Host Bus Adapter Does Not Support Both Internal And External Devices Connected To The Same SCSI Bus.

God bless pessimists, they did the backup!
