boot problem

Tonatiuh · 08-16-2006, 12:24 PM

I install Red Hat Enterprise Linux 4 update 2 into a HP Proliant server. Server has a QLogic fibre channel adapter and connected to a HP EVA.

Server has an internal disk adapter CCISS.

All the installation process performs well. When the system reboots to start for first time, it shows a message like this:

"minimal BASH-like line editing is supported..."

And only shows the "GRUB>" prompt.

I have tryed to load the kernel and boot, but it cannot identify the filesystem "/" to mount.

I have repeated the installation process several times always with same result.

Any idea?

It would appear that you do not have a valid grub.conf (or menu.lst) file or that grub cannot find it.
You can still boot if you know a couple of things.

Are you doing this properly?
It should be like:

Code:

grub> root (hd0,0)
 Filesystem is ext2fs, partition type 0x83

Now let's find a kernel:

Code:

grub> kernel /[Tab]       #  press Tab here if you have a separate /boot partition, or:
grub> kernel /boot/[Tab]  #  ..if you _don't_ have a separate /boot partition
Possible files are: bzImage-2.6.16 vmlinuz-2.6.16  #  or whatever....

After identifying your kernel do:

Code:

grub> kernel /boot/bzImage-2.6.16 root=/dev/hda2 # root is where your '/' partition is...
grub> boot

..And you should be booting. After you get booted up write a grub.conf file and reinstall grub to the MBR...see the grub docs for how.

Problem is solved now. The problem was an external storage. The server detected many devices and (I think so) it got confused about which device has the boot. I disconnected the external storage and everything worked fine.

Ok, that is good.
In future please _do_ post back that you got it sorted. Would have saved me a lot of typing

Cheers.
