Setting Up Resynchronization for Asynchronous Periodic Mode
Setting the Synchronization Period
For remote copy to automatically resynchronize asynchronous periodic mode volume groups, you
must configure the synchronization period for the volume group. There is no default synchronization
period.
To set the synchronization period, use the setrcopygroup command.
See the HP 3PAR Command Line Reference for complete details on the setrcopygroup command.

You can set the synchronization period any time after you create the volume group, even after you
start remote-copy operations for the group.
When you set the synchronization period for the primary volume group, remote copy communicates
the specified synchronization period to the secondary volume group.
When you set the synchronization period, you specify the interval between each synchronization
start time.
For example, if you set the synchronization period to 10 minutes and one synchronization begins
at 1 pm (and completes within the 10 minute synchronization period), the next synchronization
begins at 1:10 pm, the next at 1:20 pm, and so on.
