CAUTION:
The volume groups must be started before you continue to the next step and issue
the setrcopygroup restore command.

To restore the natural direction of data flow to the remote-copy system, issue the following
command on the failover system (SystemB):
# setrcopygroup restore -f -t <target_name>
where <target_name> represents the name of the target (recovered) system (SystemA).
The setrcopygroup restore command:
•
Starts tasks for each group that was recovered.
•
Starts a final synchronization from the synchronous backup system (SystemB) to the
asynchronous periodic backup system (SystemC) to ensure that the asynchronous periodic
backup system has the most recent data.
•
Stops the volume groups.
•
Switches the secondary volume groups on the primary system (SystemA) to primary volume
groups.
•
Switches the primary volume groups on the synchronous backup system (SystemB) to
secondary volume groups.
•
Returns the recovered system (SystemA) to the role of primary system.
•
Starts remote copy on the primary system (SystemA).
The following example shows the list of tasks on the synchronous backup system (SystemB):
# setrcopygroup restore -f -t SystemA
restore started with tasks: 5759
