NOTE:
•Do not add any comments after specifying 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.

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 at the recovery cluster. Prior to 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. Based on the arrays in your environment, see the respective chapters of this manual to configure replication.
Setting up Redundant Complex Workload in the Recovery Cluster
After the Site Controller Package is created at the primary cluster, an identical complex workload and Site Controller Package must be created on the recovery cluster.
Following are the topics discussed in this chapter:
1.Configuring the storage device for the complex workload at the recovery cluster
2.Configuring the identical complex workload stack at the recovery cluster
3.Halting the complex workload on the recovery cluster
Configuring the Storage Device for the Complex Workload at the Recovery Cluster
The storage device for complex workload must be configured for the data of the complex workload from the replicated disks at the recovery cluster. The procedure to configure the storage device differs if CFS, CVM, and SLVM is used.
Following are the topics discussed in this section:
•Configuring the Storage Device using CFS or SG SMS CVM in a modular style package
•Configuring the Storage Device using CFS in a legacy style package
•Configuring the Storage Device using SG SMS CVM in a legacy style package
•Configuring the Storage Device using VERITAS CVM
•Configuring the Storage Device using SLVM
Configuring the Storage Device using CFS or SG SMS CVM in a Modular Style Package
By using modular style packages, Serviceguard enables you to manage all the CVM diskgroups and the CFS mountpoints required by an application within a single package. This helps in significantly reducing the number of packages to be managed by a cluster administrator.
Complete the following procedure on the CVM cluster master node in the recovery cluster:
