3.Apply the empty Site Controller Package configuration file in the recovery cluster.
# cmapplyconf
IMPORTANT: Ensure there are no packages configured with the critical_package or managed_package attributes in the Site Controller Package configuration file. These attributes must be configured only after configuring the Site Safety Latch dependencies.
Configuring the Site Safety Latch Dependencies in the Recovery Cluster
After the Site Controller Package configuration is applied, the corresponding Site Safety Latch is automatically configured in the recovery cluster. This section describes the procedure to configure the Site Safety Latch dependencies.
Complete the following procedure to configure the Site Safety Latch dependencies:
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 RAC MNP stack on the recovery cluster.
Run the following command from a node in the recovery cluster:
# cfsdgadm add_ems <cvm_dg_name> /dts/mcsc/cw_sc 40 "!= DOWN"
NOTE: Specify the condition as != DOWN with a space before the word Down. Ignoring the space will result in the cfsdgadm command failing.
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 recovery cluster. If you have VERITAS CVM configured in your environment, add the EMS resource details in the CVM disk group packages in the recovery cluster.
resource_name /dts/mcsc/cw_sc resource_polling_interval 120 resource_up_value != DOWN resource_start automatic
When using SLVM or VERITAS CVM configured, run the cmapplyconf command to apply the modified package configuration.
2.Verify the Site Safety Latch resource configuration in the recovery cluster. Run the cfsdgadm show_ems command:
# cfsdgadm show_ems <dg_name>
RESOURCE_NAME /dts/mcsc/hrdb_sc
RESOURCE_POLLING_INTERVAL 40
RESOURCE_UP_VALUE != DOWN
