LVM Online Disk Replacement (LVM OLR)

Determining whether LVM OLR is available on the system
The feature is available in LVM patches for HP-UX 11.11 and 11.23. Both command and
kernel components are required to enable the feature:
o For 11.11: Patches PHKL_31216 and PHCO_30698 (or superseding patches)
o For 11.23: Patches PHKL_32095 and PHCO_31709 (or superseding patches)
LVM OLR will also be available in the next HP-UX release after 11.23 (11i V2).
The pvchange(1M) command can be employed to determine whether LVM OLR is
available: just attempt to reattach any LVM device:
pvchange -a y path
If the feature is not available on the system, the command will fail with a message
indicating that the option is illegal or that the HP-UX kernel does not provide the feature.
See LVM OLR messages 1 and 2 in the LVM OLR Messages section for a complete
description of these messages. When LVM OLR is properly installed, the command may
succeed or fail, but will never display these messages.
