8.7
Physical Copies
InForm OS Version 2.3.1 3PAR InForm CLI Administrator’s Manual
◆ <destination_VV> is the name of the destination volume. The destination volume
must be equal or greater in size to the parent volume, must be a writeable base volume,
and must not be exported as a VLUN.
For information on arguments which can be optionally specified with the
creategroupvvcopy command, refer to the InForm OS Command Line Interface
Reference.
8.3.2 Resynchronizing a Physical Copy
At some point, you may want to resynchronize a physical copy with its original base volume
because either virtual volume could have been modified since the copy operation was
launched. When you resynchronize a physical copy, the system copies changes from one
volume in the physical copy pair to the other.
 To resynchronize a physical copy, issue the createvvcopy -r <destination_VV>
command, where
-r <destination_VV> is the volume to be resynced with its parent
volume. The snapshot is retained for quick resynching and the parent-copy relationship is
also retained.
8.3.2.1 Resynchronizing a Group of Physical Copies
Just as groups of physical copies can be created for a list of virtual volumes, those physical
copies can also be resynced.
 To resynchronize a group of physical copies, issue the creategroupvvcopy -r
<destination_VV>
command, where -r <destination_VV> is the volume to be
resynced with its parent volume.
Snapshots of the parent volume must have been saved during their creation (using the
-s
option) in order to resynchronize the volumes.
NOTE: If you wish to copy multiple volumes, the
<parent_VV>:<destination_VV> argument can be repeated multiple times
on the command line for a single instance of the
creategroupvvcopy
command.
