Thanks wisecracker for the reply.

In the link Linux lvm - Logical Volume Manager in section "Mount logical volumes" when the logical volume is mounted why does df -h output shows the volume mounted in dev/mapper?

In link Logical volume management also shows the same in section "Listing 8. Mounting the LV".
