1.If you have SG SMS CVM or CFS configured in your environment, add the EMS resource dependency to all DG MNP packages in the complex workload stack in the primary cluster.

If you have SLVM configured in your environment, add the EMS resource details in the packages that are the foremost predecessors in the dependency order among the workload packages in the primary cluster. If you have Veritas CVM configured in your environment, add the EMS resource details in the CVM disk group packages in the primary cluster.

resource_name /dts/mcsc/cw_sc resource_polling_interval 120 resource_up_value != DOWN resource_start automatic

Run the cmapplyconf command to apply the modified package configuration.

2.Verify the Site Safety Latch resource configuration in the primary cluster. Run the following command to view the EMS resource details:

#cmviewcl -v –p <pkg_name>

3.Configure the Site Controller Package with complex-workload packages in the primary cluster.

site <site1>

critical_package <site1>_cw managed_package <site1>_cw_dg managed_package <site1>_cw_mp

NOTE:

There must be no comments in the same line as the critical and managed packages.

Always set auto_run parameter to yes for failover packages configured as critical or managed packages.

The packages configured with mutual dependency must not be configured as critical or managed packages.

4.Re-apply the Site Controller Package configuration.

#cmapplyconf -v -P /etc/cmcluster/cw_sc/cw_sc.config

After applying the Site Controller Package configuration, you can run the cmviewcl command to view the packages that are configured.

Suspending the replication to the recovery cluster

In the earlier procedures, the complex workload and Site Controller package were created in the primary cluster. Now, an identical complex workload using the target replicated disk must be configured with the complex workload stack in the recovery cluster. Before creating an identical complex workload at the recovery cluster, ensure that the Site Controller Package is halted in the primary cluster. Split the data replication such that the target disk in the recovery cluster is in the Read/Write mode.

The procedure to split the replication depends on the type of arrays that are configured in the environment.

For information about splitting the replication on XP P9000, see Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access for P9000 and XP A.11.00 available at http://www.hp.com/go/hpux-serviceguard-docs.
