Description :
units() Get or set the units used to report sizes of LVs, PVs, etc.
legal values: hbskmgtpeHBSKMGTPE
see man lvm documentation of --units
get_volume_group_list() This routine will return an array that
contains the names of the volume groups.
AATTvgs = get_volume_group_list(); print \"AATTvgs \
\";
Would yield the following: vg00
get_volume_group_information($) This routine will return all of
the volume group information about
the specified volume group.
%vg = get_volume_group_information(\"vg00\");
foreach(sort keys %vg) {
print \"$_ = $vg{$_}\
\";
}
Would yield the following:
access = read/write
act_pv = 2
alloc_pe = 3840

get_logical_volume_information($) This routine will return all of the
logical volume information associated
with the specified volume group.
%lv = get_logical_volume_information(\"vg00\");
foreach $lvname (sort keys %lv) {
foreach(sort keys %{$lv{$lvname}}) {
print \"$_ = $lv{$lvname}->{$_}\
\";
}
print \"\

get_physical_volume_information($) This routine will return all of the information
information about the physical volumes assigned
to the specified volume group.

foreach $pvname (sort keys %pv) {
foreach(sort keys %{$pv{$pvname}}) {
print \"$_ = $pv{$pvname}->{$_}\
\";
}
print \"\

}
Would yield the following results:

status = available / allocatable
total_pe = 2160
device = /dev/hda4
free_pe = 864

get_lv_info($) This routine will return all of the information about the
specified logical volume. The information will be returned
in a hash.
get_lv_info
