Any utility program to dump and create LVM table ?

[Steven Shiau]

Hi,
I am new to LVM, and I am wondering is there any program which can dump
the LVM table to a file or create LVM table from a file ?
What I mean is just like sfdisk to partition table, I can use
sfdisk -d /dev/hda > hda.pf
to dump the partition table.
And with this file "hda.pf", I can easily create a partition table in
another HD like:
sfdisk /dev/hda < hda.pf

I know with vgs, pvs, and lvs maybe I can write a script. But if such a utility program exists, then that's easier.

Thanks in advance.
