4. On the recovered system (System2), issue the following command to verify that the volume
groups are started:
# showrcopy groups <group_name>
where <group_name> represents the volume group that should be started
(periodic_group_1).
Solution Problem
The volume groups are not
started. 1. On the recovered system, issue:
startrcopygroup <group_name>
or:
startrcopygroup -pat <pattern>
where -pat <pattern> represents the pattern of volume group names (for
example, periodic*).
2. Wait for the synchronizations to complete before continuing.
CAUTION: The volume groups must be started before you continue to the next step and issue
the setrcopygroup restore command.
5. On the failover system (System1), issue the following command to restore the natural direction
of data flow to the remote-copy pair:
# setrcopygroup restore -t <target_name>
where <target_name> represents the name of the target system (System2).
