LVM: Duplicate VG name VolGroup00
Solution 1
From the man page:-
"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".
...so for your case:-
vgrename zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 newvolgroupname
...will rename the volume group with ID zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 to newvolgroupname.
Solution 2
Name
vgrename - rename a volume group Synopsis
vgrename [-A|--autobackup {y|n}] [-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
Link: http://linux.die.net/man/8/vgrename
... as for
Volume group name cciss/c0d1 has invalid characters
/dev/cciss/c0d1
is not a VG, so you cannot rename it. This is a PV on which a VG is probably based.

I'm on a server that shows a duplicate VG name. How can I rename one of these VolGroups to get rid of this conflict?

My quick attempt to re-name the VolGroup (could be doing this wrong...):
