Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

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>
3. Configure the Site Controller Package with complex-workload packages in the recovery cluster.
The following example depicts configuring the Site Controller Package with RAC database
package using CFS:
site site3
critical_package site3_hrdb
managed_package site3_hrdb_dg
managed_package site3_hrdb_mp
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.
4. Re-apply the Site Controller Package configuration.
# cmapplyconf -v -P /etc/cmcluster/hrdb_sc/hrdb_sc.config
After applying the Site Controller Package configuration, you can run the cmviewcl command
to view the packages that are configured.
Configure Continentalclusters
Ensure that the Continentalclusters software is installed on all nodes in both primary and recovery
cluster. To configure the Continentalclusters, complete the procedure described in “Designing
Continentalclusters” (page 36).
Configure a Continentalclusters Recovery Group
For each Site Controller Package in the cluster, configure a recovery group using the corresponding
packages at the primary and recovery cluster.
Complete the following steps to configure a recovery group in Continentalclusters:
1. Edit the Continentalclusters configuration file to specify the recovery groups. Specify the Site
Controller Package configured in primary cluster as a PRIMARY_PACKAGE and the Site
Controller Package configured in the recovery cluster as a RECOVERY_PACKAGE in the recovery
group.
For example:
RECOVERY_GROUP_NAME hrdb_sc_group
PRIMARY_PACKAGE <primary_cluster_name>/hrdb_sc
RECOVERY_PACKAGE <recovery_cluster_name>/hrdb_sc
2. Check the configuration file syntax.
# cmcheckconcl -v -C <Continental_cluster_config_file_name>
3. Apply the configuration.
# cmapplyconcl -C <Continental_cluster_config_file_name>
For more information on configuring Continentalclusters, see “Designing Continentalclusters”
