Dave,

You ask 4 different but related questions. Remember,

A LUN on an array like the EVA looks like a physical disk to HP-UX, a copy (e.g. snapshot) looks like a differnet disk.

An LVM VG is made up of 1 or more Physical disks (or LUNs) all the disks must be consistant for LVM to work. You cannot restore a copy of one of the disks from yesterday and leave all the other disks in the LV group from today and expect LVM to work. If you deactivate the VG and restore all the disks in the group to the same point in time, then you could reactivate the group and LVM would be happy, (unless the number of disks or lvols in the group changed since then)

vgimport assumes you have a complete set of disk with LVM already on them. You can use vgimport to bring them into a system.

typically vgimport is used to move LVM volume groups between systems, or add a copy of a VG on another system using clone copies of all the disks in the original VG.
