linux boot problem

sambaiah — Fri, 26 Jul 2002 06:15:48 GMT

Hello All,
We are running LH6000 Netserver with netraid
raid5 configuration with RedHat 6.2. Bios is
not able to see logical drive. HP support people
came and set it right. Now bios is able to see
logical drive but lilo is giving error 0x01.
If we boot rescue and try to mount it is not
mounting. Some where partition table is corrupt.
Is there any way to recover it?

thanks,
Sam

Hi

you may download linux bootable-cd image from linuxcare, then boot it up from the cd.
http://lbt.linuxcare.com/download.epl

From shell, can you find the partition? # fdisk -l /dev/sda shows you the partition table of your disk.

If you can see partitions in your HD, mount them then
# chroot /mount-point /bin/bash
then
# /sbin/lilo -v

to modify your LILO.
Because error 0x01 seemed you have corrupted boot loader in MBR.

Good luck

Hi All,
Thanks for response. It seems the problem
is with RAID 3 and 5 confusion. It has RAID 3
and then because of nvram problem support people restored and put RAID 5. I tried with
RH rescue or floppy linux versions and partitions are not recognised even with
fdisk -l /dev/sda etc.

Do I need to go any disk recovery utilities
like R-studio or any other way to get it. Are
there any tools alternative to R-studio are
there?

thanks,
Sam
