HW: 
Proliant DL580
-(1) 700 Mhz PIII Xeon processor
-512 MB RAM
-Integrated Smart Array controller with ROC firmware v. 1.46 enabled as 
primary/boot controller
-(4) 18.2 GB drives configured as (1) logical RAID 5 volume as 
primary/boot disk

SW:
-Smart Start 5.0
-Successful installation of Red Hat 7.1
-Red Hat 7.2 beta 2

STEPS TAKEN TO ENCOUNTER PROBLEM:

-Use a current version of Smart Start to perform a manual configuration of 
the server.  This will create a 36 MB Compaq System Partition at the 
beginning of the available space on the boot disk

-Perform a successful installation of Red Hat Linux 7.1, with your boot 
disk being partitioned as follows:
   -1st partition, primary, 36MB, Compaq System Partition
   -2nd partition, primary, 50MB, Linux ext2 fs, mounted as /boot
   -3rd partition, primary, 512MB, Linux swap
   -4th partition, primary, remainder of disk space, Linux ext2 fs, /

-Once installation is performed, boot once to make sure OS landed properly.

-Reboot system with Red Hat 7.2 beta 2 CD1 and start the installation 
interview

-Proceed through the installation interview to the 'Installation Type' 
screen.  Select 'Upgrade Existing System' and click 'Next'

-At the 'Upgrade Examine' screen, Anaconda appears to crash, indicating 
that in unhandled exception has occured.  I've saved the Anaconda dump 
file and will append it to this issue in the "Notes" section.

-On this same system I re-installed Red Hat 7.1, this time deleting the 
Compaq System partition so that my boot disk is now partitioned as follows:
   -1st partition, primary, 50MB, ext2 fs, mounted /boot
   -2nd partition, primary, 512MB, swap
   -3rd partition, primary, remainder of disk, ext2 fs, mounted /

-This time, with the Compaq System partition no longer the 1st partition, 
no longer existing, I can upgrade from Red Hat 7.1 to Red Hat 7.2 beta 2.
