Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

To list all volumes on which Persistent FastResync is enabled, use the following
command:
# vxprint [-g diskgroup] -F "%name" -e "v_fastresync=on \
&& v_hasdcolog"
Disabling FastResync
Use the vxvol command to turn off Persistent or Non-Persistent FastResync for
an existing volume, as follows:
# vxvol [-g diskgroup] set fastresync=off volume
Turning off FastResync releases all tracking maps for the specified volume. All
subsequent reattaches do not use the FastResync facility, but perform a full
resynchronization of the volume. The full resynchronization occurs even if you
turn on FastResync later.
Performing online relayout
Note: To use this feature, you need a full license.
You can use the vxassist relayout command to reconfigure the layout of a
volume without taking it offline. The general form of this command is as follows:
# vxassist [-b] [-g diskgroup] relayout volume [layout=layout] \
[relayout_options]
If you specify the -b option, relayout of the volume is a background task.
The following destination layout configurations are supported.
Concatenated-mirrorconcat-mirror

Concatenatednomirror
