HP -UX 11i Administrator's Manual page 80

The table shows that without renumbering physical extents, a max_pv of 35 or lower permits
a max_pe sufficient to accommodate the increased physical volume size.
# vgmodify -v -t -n vg32
Volume Group configuration for /dev/vg32 has been saved in
/etc/lvmconf/vg32.conf
Current Volume Group settings:
VGRA space (Kbytes) on all Physical Volumes:
Volume Group optimized settings (PEs renumbered lower):
max_pv(-p) max_pe(-e) Disk size (Mb)
The table shows that if physical extents are renumbered, all values of max_pv permit a max_pe
large enough to accommodate the increased physical volume size.
For this example, select a max_pv of 10, which permits a max_pe value of 10748.
4. Preview the changes by using the -r option to vgmodify as follows:
# vgmodify -p 10 -e 10748 -r vg32
Current Volume Group settings:

5. Deactivate the volume group as follows:
