Configuring the Site Safety Latch Dependencies in the Primary Cluster
After the Site Controller Package configuration is applied, the corresponding Site Safety Latch is
automatically configured in the cluster. This section describes the procedure to configure 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 primary cluster.
Run the following command from a node in the primary cluster:
# cfsdgadm add_ems <cw_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 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
When using SLVM or VERITAS CVM, run the cmapplyconf command to apply the modified
package configuration.
2. Verify the Site Safety Latch resource configuration in the primary cluster. If you have SG SMS
CVM or CFS configured in a legacy package in you environment, run the following command
to view the EMS resource details:
# cfsdgadm show_ems <dg_name>
RESOURCE_NAME /dts/mcsc/cw_sc
RESOURCE_POLLING_INTERVAL 40
RESOURCE_UP_VALUE != DOWN
If you have SLVM configured in your environment, run the following command to view the
EMS resource details:
# cmviewcl -v –p <pkg_name>
If you have VERITAS CVM configured in your environment, run the following command to
view the EMS resource details:
# cmviewcl -v –p <CVM_diskgroup_pkg_name>
# cmviewcl -v -p <CFS_pkg_name>
If you have SG SMS CVM or CFS configured in a modular package in your environment, run
the following command to view the EMS resource details:
# cmviewcl -v -p <SG_SMS_CVM_diskgroup_pkg_name>
3. Configure the Site Controller Package with complex-workload packages in the primary cluster.
The following example depicts configuring the Site Controller Package with complex workload
packages using CFS:
site <site1>
critical_package <site1>_cw
managed_package <site1>_cw_dg
managed_package <site1>_cw_mp
