Bug 55657

From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-2 i686)

Description of problem:
I had a similar problem installing RedHat 7.1.  See Bugzilla #41790
The actions I took to resolv it then aren't working now.

Here goes...
I boot from the CD and go through the menus.  When I get to the
installation type I choose custom.  Then, on the disk partitioning screen,
I choose disk druid.  When I pick next, I get a window popping up that says 

"The partition table on device SDA was unreadable.  To create a new
partition, it must be initialized, causing the loss of ALL DATA on this
drive.  Would you like to initialize this drive?"

I click yes, and get the following pop-up:

"Error opening /tmp/sda: No such device or address"

Clicking <retry> doesn't help.

I get identical behavior if I choose fdisk instead of disk druid.

sda is the RAID 1 volume on a 3ware Escalade 6200
It was previously partitoned & formatted ext2 and fat32 by RedHat 7.1. 
Everything appeared to be working fine when I started the RH7.2 install.

As I said, I had a similar problem installing 7.1, so I tried what I did
there:

1. hit <ctrl><f2> to get to a command prompt
2. mknod sda
3. fdisk sda

Now I can see the disk OK
I tried deleting the partitions, no change.
Then I rebooted and tried creating one big partition.  Again, no change.

If I boot from the 7.1 install CD, everything works fine.  I can see sda
properly without going into fdisk during the install.

I have also tried expert mode install.

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


How reproducible:
Always

Steps to Reproduce:
1.Attempt to install
2.
3.
	

Actual Results:  As described above

Expected Results:  Proper detection of sda, and continued install
