SYNOPSISDESCRIPTION
is an ASCII file that stores the volume-group information for all of
the physical volume groups in the system. The information is stored in
a hierarchical format.
First, it starts with a volume group under which multiple physical vol‐
ume groups can exist. Under each physical volume group, a list of
physical volumes can be specified. There must be at least one physical
volume group in each volume group that appears in this file. The phys‐
ical-volume-group name must be unique within the corresponding volume
group, although it is permissible to use a common physical volume group
name across different volume groups. There can be as many volume
groups in this file as there are in the system.
Instead of using the and commands, the administrator can edit this file
to create and extend physical volume groups. However, care must be
taken to ensure that all physical volumes to be included in the file
have already been defined in their respective volume groups by previous
use of or
The file format has the following structure. and are keywords that
introduce the names of the volume group and physical volume group,
respectively.
pv_path

pv_path

The variables are defined as follows:
pv_path The block device path name of a physical volume
within the volume group.
pvg_name The name of the physical volume group. It must
be unique within the volume group.
vg_name The path name of the volume group.
EXAMPLES
The following example shows an file containing two volume groups: the
first containing two physical volume groups, each with two physical
volumes defined in it; the second containing three physical volume
groups, each with one physical volume defined in it.
