NAME

       vgrename - rename a volume group

SYNOPSIS

       vgrename  [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-t|--test]
       [-v|--verbose] OldVolumeGroup{Path|Name|UUID} NewVolumeGroup{Path|Name}

DESCRIPTION

       vgrename renames an existing  (see  vgcreate(8)  )  volume  group  from
       OldVolumeGroup{Name|Path|UUID} to NewVolumeGroup{Name|Path}.

OPTIONS

       See lvm for common options.

Examples

       "vgrename /dev/vg02 /dev/my_volume_group" renames existing volume group
       "vg02" to "my_volume_group".

       "vgrename vg02 my_volume_group" does the same.

       "vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp"
              changes the name of the Volume Group with UUID Zvlifi-Ep3t-e0Ng-
              U42h-o0ye-KHu1-nl7Ns4 to "VolGroup00_tmp".

              All the Volume Groups visible to a system need to have different
              names.  Otherwise many LVM2 commands will refuse to run or  give
              warning messages.

              This   situation  could  arise  when  disks  are  moved  between
              machines.  If a disk is connected and it contains a Volume Group
              with  the  same  name  as  the Volume Group containing your root
              filesystem the machine might not even boot correctly.   However,
              the  two  Volume  Groups should have different UUIDs (unless the
              disk was cloned) so you can rename one of the conflicting Volume
              Groups with vgrename.
