Install RH7.2, put everything into 1 big drive + swap 2. 3. Additional info:
The modprobe error only appeared after trying different things with lilo.conf
What are the contents of your /etc/modules.conf and your /etc/lilo.conf?

Your /etc/modules.conf is broken and missing the 'alias scsi_hostadapter' line to show which scsi module to load.
Help me understand why that wasn't added by the installer? You are trying to close this, but you haven't answered why it happened. We need to find the source, not just fix the symptom.
Upgrades don't work if you're upgrading from a system which wasn't correctly set up in the past. anaconda always writes out /etc/modules.conf to contain scsi_hostadapter lines as needed on a fresh install but does not reprobe or change any of that on an upgrade to avoid breaking customizations made by the user.
