==Fix Grub on a HP Proliant DL380 G2==
see [[bugzilla:7024]] for more information
The server is configured using the Hardware RAID in RAID5, 6 drives as 1 logical drive (1 spare).
The forum posts describing the issues is [http://forums.contribs.org/index.php?topic=48808.new;topicseen#new here]:
The solution posted by CharlieBrady on the forums can be found [http://nozell.com/blog/2004/05/08/some-tips-to-reinstall-grub-on-an-hp-proliant-server/ here]:
System information:
HP Proliant DL380 G2
Dual P3 1.266GHz (original system processors)
Memory: 2GB RAM
Hard Drives: 6x 36.4GB
Compaq Hot-swappable 36.4GB, 10k or 15k RPM (mixed set) (BF03664664)
To re-configure GRUB, I followed these steps
1. Rename /etc/grub.conf to /etc/grub.old
2. edit /etc/grub.conf
3. uncommented the line that starts with #boot=
4. edited the boot= line to read
boot=/dev/cciss/c0d0
This line previously read (if i remember correctly) #boot=/dev/md0
5. opened /boot/grub/device.map
5a. I don't remember if the (hd0) line was correctly set. It SHOULD read
(hd0) /dev/cciss/c0d0
6. Ran GRUB with the following parameters:
/sbin/grub --batch --device-map=/boot/grub/device.map
--config-file=/boot/grub/grub.conf --no-floppy
7. Ran the following commands in grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit
8. Restarted the server
At this point, everything ran properly
