Operating System Software Owner manual

• <target_name> - Name of the target system with which to synchronize (SystemA)
The setrcopygroup recover command:
• Switches the volume groups on the recovered system (SystemA) to secondary mode
• Copies data from the reversed volume groups on the failover system (SystemB) 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 (SystemB).
In this example, Remote Copy copies data from the virtual volumes in volume group
multi.1.r96 on SystemB to multi.1 on SystemA.
• Starts Remote Copy on the recovered system (SystemA)
For example, the list of tasks launched by the setrcopygroup recover command on
SystemB looks like:
# setrcopygroup recover -f -t SystemA

3. Verify that the primary system is up and the Remote Copy pairs are synchronized:
a. Issue the showrcopy command on the failover system (SystemB).
