vgrename - rename a volume group
vgrename [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-t|--test] [-v|--verbose] OldVolumeGroup{Path|Name|UUID} NewVolumeGroup{Path|Name}
vgrename renames an existing (see vgcreate(8) ) volume group from Old- VolumeGroup{Name|Path|UUID} to NewVolumeGroup{Name|Path}.
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 mes- sages. 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 dif- ferent UUIDs (unless the disk was cloned) so you can rename one of the conflicting Volume Groups with vgrename.
