I can't boot into my OS

No idea what happened but one of our DBAs was working on the box. THe server rebooted and never came back up. I go look at the console and guess what? A blinking cursor. After the POST messages, the box tries to boot into the OS but I see nothing but the cursor. I tried reinstalling GRUB but that didnt work. I tried breaking the array, that didnt work.

The data seems to be intact as I was able to chroot into the image when I booted into rescue mode. Any ideas?
 
So you don't even get the GRUB menu?

Is the partition with /boot marked active? If you installed GRUB into the MBR it shouldn't matter, but it's something simple to check.

By reinstall GRUB do you mean the RPM package or the MBR code via grub-install?
 
Grub is on mbr, there is a /boot.

I reinstalled grub using grub-install.

Now I forgot to mention, this thing has some raw device mappings for the oracle stuff.
Just for kicks I removed the connection to the fibre switch. It didn't help anyways.
 
Did you reinstall grub via the chroot or rescue mode? Are you sure there's no other devices in there that the BIOS might be trying to boot from?
