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).

In this example, HP 3PAR Remote Copy copies data from the virtual volumes in volume
group multi.1.r96 on SystemC to multi.1 on SystemA.

Starts remote copy on the primary system (SystemA)

The following example shows the list of tasks launched by the setrcopygroup recover
command on SystemC:

# setrcopygroup recover -f -t SystemA
