Ok, the reason is probably doesn't have a name is because the new
install "sda" took the old name so it is probably all confused about
names.

What appears in /dev/mapper?

If you can get it sorted out through commands and getting it to
actually see the old name, a quick and possible solution is to
re-install on the new drive again, only when it comes to the lvm, edit
the configuration to use a different vg name.  I think you are going
to have a problem getting it to see the name atm since it is taken up
by the new install.

also checkout out "vgchange -a"
