d. Verify that:
• the Status of the target system (System2) is ready
• the Status of all sending links is Up
• the Role of the synchronizing volume groups is Secondary-Rev
• the SyncStatus of all volumes in the Secondary-Rev volume groups is Synced
For example, the showrcopy output on System1 looks like:
# showrcopy

SolutionProblem
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),
enter either:
syncrcopy <group_name>
• <group_name> - Reversed volume group (for example,
periodic_group_1.r96)
or:
syncrcopy -pat <pattern>
• -pat <pattern> - Pattern of reversed volume group names (for example,
periodic*)
