Device order screwing up boot loader

Posted on 2002-07-23
Last Modified: 2010-04-20
I am trying to get RH 7.2 working on a system that has both a raid card and a qlogic fibre channel controller.  The installer picks up the qlogic as /dev/sda and the raid array as /dev/sdb.  The purpose of the raid array is to install the OS but when it comes time to install the boot loader it wants to install it in the MBR of /dev/sda... I tried installing LILO on the boot sector of the raid array but when the system reboots all I get is an "L" on the string when LILO is supposed to start.  In rescue mode when I run 'lilo -v' I get. "Warning /dev/sdb1 is not on the first disk".  The LILO docs say that this would keep the system from booting. GRUB has similar problems.

I have tried setting the order the system bios detects the cards but that didn't help.  Is there any way to force linux to see the raid array as first scsi disk?

Thank you anyone who can help

at lilo's prompt try:
   image-name boot=/dev/sdb

I might just do that if lilo would even load.  I do not get past the first stage loader.  I do not get a prompt.  Thanks for trying though.

boot from other media (CD, floppy) and install a new MBR using


in /etc/lilo.conf
