Command to see the logical volume path, device mapper path and its corresponding dm device path

Currently I am using this laborious command
Code:
lvdisplay | awk '/LV Path/ {p=$3} /LV Name/ {n=$3} /VG Name/ {v=$3}  /Block device/ {d=$3; sub(".*:", "/dev/dm-", d); printf "%s\t%s\t%s\n", p, "/dev/mapper/"v"-"n, d}'

Would like to know if there is any shorter method to get this mapping of combined output (lvpath, /dev/mapper/ and /dev/dm/* ), possibly a single command.

The socket mapping file, /etc/sock2path, is a system file that contains the mappings between the socket(3SOCKET) call parameters and the transport provider driver. Its format is described on the soconfig(1M) manual page. The init(1M) utility uses the soconfig utility with the sock2path file during the booting sequence. EXAMPLES
