Configuring the agent for EMC SRDF/Star
You can adapt the most clustered applications to a disaster recovery environment by:
Converting their devices to be part of the SRDF/Star composite group
Synchronizing the devices
Creating a resource of type SRDF/Star and adding it to the service group
Symmetrix device groups are configured as resources of type SRDF/Star.
Ensure that you get the OnlineTimeout and OnlineRetryLimit attributes for the SRDF/Star resource so that its entry points do not time out, or so that they are automatically restarted if they do not time out.
After configuration, the application service group must follow the dependency diagram.
See Sample configuration.
Note:
You must not change the replication state of devices from primary to secondary and from secondary to primary, outside of a VCS setup. The agent for EMC SRDF/Star fails to detect a change in the replication state if the role reversal is done externally and RoleMonitor is disabled.
