Here are some LVM volume group selection examples:

all: analyze all LVM Volume Groups (all except Root VG)

listvg:list all LVM Volume Groups

list: list all disk devices

vg_name:a single LVM Volume Group, named vg_name

<pattern>:for example vg08 vg09 vg05

Select volume groups to analyze: [<pattern

list>,all,list,listvg,q,?] vg08

Name a new disk group [<group>,list,q,?] (default: dg08)

Each volume group will be analyzed one at a time. If there are any

in this list that you do not want to analyze, you can either
