+"vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp" renames a volume group with UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to the volume group named "VolGroup00_tmp".  Using the UUID option to name a volume group may be useful in cases where one machine has two physical volumes, each with the same volume group name, but a separate volume group UUID (this situation will cause error messages with lvm commands).  One way duplicate volume group names occur is if an old disk with a root volume is moved to a new machine with its own root volume.  In this case, both volume groups may have the same name (for example, "VolGroup00"), but different UUIDs.
