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".

NAME
lvremove - remove a logical volume SYNOPSIS
lvremove [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...] DESCRIPTION
lvremove removes one or more logical volumes. Confirmation will be requested before deactivating any active logical volume prior to removal. Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem). Removing an origin logical volume will also remove all dependent snapshots. If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com- mand issued from one node can do this. OPTIONS
See lvm(8) for common options. -f, --force Remove active logical volumes without confirmation. EXAMPLES
Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation: lvremove -f vg00/lvol1 Remove all logical volumes in volume group vg00: lvremove vg00 SEE ALSO
