Accessing disk from F19 in F21

[Markus Lindholm]

Hi

I just updated a computer from Fedora 19 to 21. I did it by adding a
second SSD to the computer on which I installed F21. The problem is
now that I can't access the files from the old SSD. They seem to be
overshadowed as the volume group has the same name as the new
installation.

Any way to get access to the old disk in this new setting?
