I think you are looking for vgchange and not pvchange for this.

It is helpful to name your vg's something other than letting the  
system name them. that way you won't have multiple vg's named the  
same, which quickly will become a nightmare to work with.

Look at dmesg and see what device it is then mount it like a normal drive.

If it is a vg then you will want to run
'vgchange -ay'
vgscan

The issue the lvs command to see your lv's.

Then you can mount the individual lv's of the vg.
