Boot stuck at GRUB

Hi all,
I've got a server HP DL380 G5 with 2 disks mirrored with RAID1. The system runs Linux redHat 5.
The server is not able to boot anymore : it display :
Attempting to boot from Hard drive
GRUB

and nothing else after.

Anyone's got any idea ?
I've already tried :
chroot /mnt/sysimage
grub-install /dev/cciss/c0d0

Still stuck with same message.
Thank you for your help.

Re: Boot stuck at GRUB

Please show us your /boot/grub/menu.lst (or grub.conf) and /boot/grub/device.map.

Errors in device.map may confuse the bootloader. If it cannot even reach GRUB boot prompt, it means only the first stages of GRUB are working.

If the device /dev/cciss/c0d0 is set as the primary boot disk in the server BIOS menus, it should be identified as (hd0) in /boot/grub/device.map. This mapping must be correct when you run grub-install.

Re: Boot stuck at GRUB

One of our DL580 systems hangs at the grub prompt starting from /dev/cciss/c0d0.

At the prompt you can start the system by entering "root (hd0,0)" then "configfile /grub/grub.conf". But that doesn't answer the question of why it stops there.

Matti, our device.map shows:

(hd12) /dev/cciss/c0d0

Are you saying that I should edit that "hd12" to "hd0"?

Re: Boot stuck at GRUB

Hi,
I've solved the pb by booting with the installation DVD
Choose "upgrade an existing installation" and "upgrade boot loader configuration"
