Hi Bryan.

I gave that a shot, but I get the error:

/dev/mapper/vg1-sysroot does not have any corresponding BIOS drive.


I double-checked the grub.conf file and everything I'd expect is there, 
so I'm not sure what steps to take next.

Let me ask this:  If you were going to upgrade drives from one to 
another, would you do what I did or is there another procedure that you 
would use?

Thanks for your help Brian.
