Raid1 on Dell Poweredge with Perc4e/Di Raid Controller running Debian Sarge (3.1)

Raid1 on Dell Poweredge with Perc4e/Di Raid Controller running Debian Sarge (3.1)

[oliver]

Hello,
I would like to use Raid1 on the Dell Poweredge with Perc4e/Di Raid Controller 
and two 2 73 GB drives running Debian Sarge (3.1).

At http://linux.dell.com/storage.shtml I read that the Powerege 2850 Perc4e/Di 
requires megaraid2 driver 2.00.3 or higher on 2.4.x kernel. On 2.6.x kernels 
(x < 9) there is no driver for these adapters. On 2.6.x (x >= 9) use the 
'megaraid_mbox' and 'megaraid_mm' drivers.

Problem: The Debian Installers offers only to install:

- 2.4.x (which seems to be okay for the raid) OR 
- 2.6.8 (which would not allow the use of the Raid)

Solution:
Is there a megaraid driver for the 2.6.8 kernel? If so, where?

If not, should I use 2.4.x kernel or try to install a 2.6.9 kernel on Debian 
Sarge?

Regards,

Hello Denis,
this is what I just did

cd /usr/src/kernel-image-2.6.8
patch -l < ./megaraid-v2.20.4.6/2.6.8-24.patch
cd /boot
cp config-2.6.8-24.14-default /usr/src/linux/.config
cd /usr/src/linux
make oldconfig 
make
make modules_install
cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.6.8
cp System.map /usr/src/linux/System.map /boot/System.map-2.6.8
[Edited /boot/grub/menu.lst]
[Added the line megaraid_mbox to /etc/modules.conf Note: there war no entry 
megaraid2 or similar in this file]
server:/boot # mkinitrd -o /boot/initrd.img-2.6.8-1 2.6.8-1
Fatal:
Fatal: Module megaraid2 not found.
Warning: This failure MAY indicate that your kernel will not boot!
but it can also be triggered by needed modules being compiled into the
kernel.

Any ideas? Please help! Thanks!

Regards,
Oliver
