HP-UX Logical Volume Manager and MirrorDisk/UX Release Notes (September 2008)

• pvmove supports moving extents to a specific location on the target physical volume. For
example, to move extents from /dev/disk/disk32 to /dev/disk/disk55, starting at
physical extent 50 on /dev/disk/disk55, use this command:
# pvmove /dev/disk/disk32 /dev/disk/disk55:50
• pvmove supports striped logical volumes and striped mirrored logical volumes.
• pvmove supports a new -p option to preview physical extent movement details without
performing the move.
For more information, see pvmove(1M).
vgmodify Online LUN Expansion
The vgmodify command supports LUN expansion on a Version 1.0 volume group without
deactivating the volume group. To reconfigure an activated volume group to take advantage of
a physical volume size increase, use the –E and –a options to vgmodify. For example, if the
physical volume /dev/disk/disk32 in volume group vg02 has been expanded, use the
following command to add physical extents to it:
# vgmodify -a -E /dev/vg02 /dev/rdisk/disk32
For more information, see vgmodify(1M).
