Re: LVM mirroring
In node that have the vg active:
vgexport with "-p" option: Preview the actions to be taken but do not update
the /etc/lvmtab file or remove the devices file.
# vgexport -p -m /tmp/vgname.map vgname
# scp /tmp/vgname.map node2:/tmp
In secondary node:
vgexport
# vgexport -m /tmp/vgname.map.old vgname
# mkdir /dev/vgname
# mknod /dev/vgname/group c 64 0xnn0000
# vgimport -m /tmp/vgname.map vgname /dev/dsk/cxtydz ...

Re: LVM mirroring
what you are trying to do is called "host based mirroring". Basically, it goes online, without even stopping the server or the application, but for this you should have the product MirrorDisk/UX installed. You should migrate it on the active server (the server your applications are running currently), after that you should bring the changes also to the passive node. (vgexport -p on the active node, the import the mapfile on the passive node.) No mountpoints/cluster config should be changed.

Re: LVM mirroring
Refer the attached LVM docs from HP. This document discusses how to deal with disk failures under the HP-UX logical volume manager and it includes strategies to prepare for disk failure, ways to recongnize that a disk has failed and steps to remove and replace a failed disk.
