Bug 236401

Description of problem:

I have a 3ware 9650-12 controller with 12 320G drives.

I defined one large raid array of ~3TB.  I then installed FC7 Test 3 with
a 2GB SWAP, 200MB BOOT, and the remainder "/" (which would be approx 2.7TB). 
Install went uneventfully but when the system booted I received a kernel panic.
 I then used the default LVM configuration, but made the "/" drive 30GB.  The
system booted fine, but I am now receiving in the startup log:
"...very big device. try to use READ CAPACITY(16) and write cache: enabled, read
cache: disabled, doesn't support DPO or FUA errors."

I submitted a question to fedora-list and was told that I need to use GPT
partition tables for partitions > 2TB and that they system couldn't boot from a
GPT partition.  It appears that anaconda didn't catch this, put the wrong type
of partition table on my "/" drive, and then allowed the installation to
continue.  The problem doesn't surface until you try to boot. 


Version-Release number of selected component (if applicable):
Fedora 7, Test 3

How reproducible:
Go thru the install procedure.  I did it three ways, using drive defaults
(letting anaconda decide), custom procedure without LVM and custom procedure
with LVM.  The way I got this to work as described above was taking the default
drive recommendations and manually changing the size of the "/" partition to 30GB.

Steps to Reproduce:
1.  Mount the install DVD
2.  Proceed with installation

  
Actual results:
System won't successfully boot after anaconda installs all the packages.

Expected results:
Sucessful boot, or at a minimum having Anaconda give some type of warning saying
"this isn't going to work" you need to do A. B. C. etc.
