8.3.1 Creating a Physical Copy
 To create a physical copy of a virtual volume, issue the createvvcopy -p <parent_VV>
-s <destination_VV>|
set:<set_name> command, where:
◆ -p <parent_VV> creates a snapshot of the parent volume, as identified by
<parent_VV>, and copies the snapshot data to the destination volume.
◆ <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 volume, and
must not be exported as a VLUN.
◆ <set_name> is the name of the destination volume set. Each virtual volume in the
destination volume set must be equal or greater in size to the parent volume, must be a
writeable volume, and must not be exported as a VLUN.
◆ -s saves the snapshot for quick resynchronization and retains the parent/copy
relationship between the parent and destination volumes.
For information on arguments that can optionally be specified with the
createvvcopy
command, refer to the InForm OS Command Line Interface Reference.
8.3.1.1 Creating a Group of Physical Copies
The InForm CLI also allows for the creation of consistent group physical copies of a list of
virtual volumes.
 To create group physical copies, issue the creategroupvvcopy -p -s
<parent_VV>:<destination_VV>
command, where:
◆ -p <parent_VV> creates a group of snapshots of the parent volume, as identified by
<parent_VV>, and copies data from the snapshots to the destination volume.
◆ -s saves the snapshot for quick resynchronization and retains the parent/copy
relationship between the parent and destination volumes.
NOTE: The creategroupvvcopy command can be issued multiple times.
However, the system allows only two physical copy tasks to run concurrently. Any
additional physical copy tasks are queued, pending the completion of the active
physical copy tasks.
