Recovery of Asynchronous Periodic Mode in SLD Remote-Copy Configurations
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 (SystemC), issue the following command:
# setrcopygroup recover -f -t <target_name>
where <target_name> represents the name of the target system with which to synchronize
(SystemA).
The setrcopygroup recover command:
• Switches volume groups on the recovered system (SystemA) to secondary mode.
• Copies data from the reversed volume groups on the failover system (SystemC) to the
corresponding volume groups on the recovered system (SystemA).
The data used to synchronize the systems includes the snapshots taken when the recovered
system (SystemA) went down, as well as recent I/O to the failover system (SystemC).
