c. Issue the showrcopy command on the recovered system (System2).
d. Verify that:
•
the Status of the target system (System1) 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 Syncing
For example, the showrcopy output on System2 looks like:
# showrcopy

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), 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*)
4. Verify that the volume groups are started. On the recovered system (System2), enter:
# showrcopy groups <group_name>
