How to import a root volume group in LVM?

[Ed Trumbull_1]

I have installed two copies of hpux on different disks on my system. I now want to be able to import the root volume group from one copy and access its data while I'm running the other copy. How do I do this?

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgimport /dev/vg01 /dev/dsk/cNtNdN
vgchange -a y /dev/vg01
mkdir /newroot
mount /dev/vg01/lvol3 /newroot

So far, so good. I've imported the volume
group, and gotten:

# vgimport /dev/vg01 /dev/dsk/c4t6d0
vgimport: Warning: Volume Group belongs to different CPU ID.
Can not determine if Volume Group is in use on another system. Continuing.
Warning: A backup of this volume group may not exist on this machine.
Please remember to take a backup using the vgcfgbackup command after activating the volume group.

Should I be concerned about the messages above, or can they be ignored?

[Pete Randall]

You can ignore them.
