Description of problem:
I don't have all the details, but basically I had to modify the grub.config file
and do a grub-install in order to get grub running properly after doing an
upgrade form 7.2 to 7.3.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.have your system boot from a scsi disk (sda)
2.install a promise technologies tx2 raid controller, have a disk running off of it.
3.upgrade from 7.2 to 7.3
	

Actual Results:  the grub part of the install thought the boot disk was the ide
drive I had hanging off my promis tx2 ata raid controller. Therefore, grub
wasn't able to boot linux. (Had to create a boot floopy to fix the problem.)

Additional info:

my guess is that what ever software is used to determine which is the boot
drive, didn't work well. I'm not sure if this is grubs fault or the redhat
upgrade software's fault.

I even tried the following. After doing the full upgrade and my system wouldn't
boot, I reinstalled (or better said re-upgrade) redhat 7.3. (I forced the
installation of the kernel packages since the grub part of the install needs
this info to build a grub.config file) At the point of the installation where it
asks what it should do regarding the boot loader, I chose the 3rd option, which
was to completely reinstall grub. This didn't work. finally after booting from
the boot disk, I modified the grub.config file by hand, did a grub-install and
now my system is working
