HP 3PAR Operating System Software - Manual (Page 129)

Recovery
1. Recover the failed system.
2. When both systems in the Remote Copy pair are ready to resume normal operation, reverse
the natural direction of data flow and resynchronize the systems.
a.
Stop I/O to the reversed volume groups on the failover system.
b. On the failover system (System2), enter:
# setrcopygroup recover -t <target_name>
•
<target_name> - Name of the target system with which to synchronize (System1)
The setrcopygroup recover command copies data from the reversed volume groups on
the failover system to the corresponding volume groups on the recovered system. In this
example, it copies data from periodic_group_1.r96 on System2 to periodic_group_1 on
System1.
3. Verify that the Remote Copy pair is synchronizing:
a.
Issue the showrcopy command on the failover system (System2).
b. Verify that for the target (recovered) system (System1):
•
the Status of the target system is ready
•
the Status of all sending links is Up
•
the SyncStatus of all volumes in the Primary-Rev volume groups is Syncing (or Synced)
For example, the showrcopy output on System2 looks like:
# showrcopy
