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}.

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.
