I'm assuming you're talking about mounting when booted from another
device. This might be helpful:

Basically:

  lvm vgscan       # find volume groups
  lvm vgchange -ay # activate them
  lvm lvs          # show VGs and LVs

Then you can:

  mount /dev/VG/LV /mntpoint 
  # replace VG and LV appropriately
