2.- use the undocument command vgmodify, but this command do not came with the regular operating system (HP-UX 11.11), and I don't know where to download it.

Interesting! vgmodify can do this and it is included with the most recent HP-UX version. It also seems to be in patch PHCO_35524, but that is for HP-UX 11.23. Try to get the lastest LVM commands patch for your OS and see if vgmodify is there.

       online reconfiguration of shared volume groups is available on volume groups version 2.1 and higher.

       The daemon is automatically started when the system boots if is in the file.  To manually start have in then enter To manually stop enter

       Only one instance of the daemon can run on a system.  An attempt to start a second instance would fail.
