Solution Problem
If I/O to the volumes on the
failover system did not stop
before the synchronization: 1. Stop I/O.
2. Manually synchronize the Remote Copy pair. On the failover system (System1),

syncrcopy
• - Reversed volume group (for example,
periodic_group_1.r96)
or:
syncrcopy -pat
• -pat - Pattern of reversed volume group names (for example,
periodic*)
