NAME

       vgrename — rename a volume group

SYNOPSIS

       vgrename  [-A|--autobackup  {y|n}] [--commandprofile ProfileName] [-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}.

       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.

OPTIONS

       See lvm(8) for common options.

Examples

       Renames existing volume group vg02 to my_volume_group:

       vgrename /dev/vg02 /dev/my_volume_group

       or

       vgrename vg02 my_volume_group

       Changes the name of the Volume Group with UUID
       Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to VolGroup00_tmp:

       vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp
