RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
Normally this may not be an issue, but when faced with two vgs with the same name yet unique vg_uuids, many lvm commands tell the user to use vgrename with --select --uuid to remedy the problem.
"Fix duplicate VG names with vgrename uuid, a device filter, or system IDs.
Multiple VGs found with the same name: skipping df
Use --select vg_uuid=<uuid> in place of the VG name."
[root@grant-02 ~]# vgs -a -o +vg_uuid

I think removing the support for -S|--select in vgrename was intentional so we always point to a single VG by directly specifying the VG UUID (which vgrename already accepts).
Also, if we used "vgrename --select <some_criteria> new_vg_name", then all VGs that match the selection criteria would be renamed to the same "new_vg_name". That is something we don't want to as we'd produce duplicate VG names this way.
So the fix here is just to change the reported "Use --select vg_uuid=<uuid> in place of the VG name." line to "Use VG UUID in place of the VG name.".
