NAME

lvmpvg − store physical volume group information for LVM

SYNOPSIS

/etc/lvmpvg

DESCRIPTION

lvmpvg 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 volume group 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 physical-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 vgcreate and vgextend 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 vgcreate or vgextend. 

The lvmpvg file format is structured as follows: VG and PVG are keywords that stand for Volume Group and Physical Volume Group respectively.  No comments are allowed in this file.

PVG physical_vol_group_name

EXAMPLES

The following example shows an lvmpvg 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. 

VG     /dev/vg00
PVG    PVG0
/dev/dsk/c2d0s2
/dev/dsk/c2d1s2
PVG    PVG1
/dev/dsk/c3d0s2
/dev/dsk/c3d1s2
VG     /dev/vg01
PVG    PVG0
/dev/dsk/c4d0s7
PVG    PVG1
/dev/dsk/c5d0s7
