Recovery of SLD Remote-Copy Configuration
1. Recover the failed system.
2. When the primary system is ready to resume normal operation, reverse the natural direction
of data flow and resynchronize the systems.
On the failover system (SystemB), issue the following command:
# setrcopygroup recover -f -t <target_name>
