NAME
       vgrename - rename a volume group

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