When using SLVM, or Veritas CVM, or SG SMS CVM/CFS configured as a modular package,
run the cmapplyconf command to apply the modified package configuration.
2. Verify the Site Safety Latch resource configuration at both sites.
If you have SLVM or Veritas CVM or SG SMS CVM or CFS configured in your environment,
run the following command to view the EMS resource details:
# cmviewcl -v –p <pkg_name>
Modifying Site Controller to manage complex workload
1. Configure the Site Controller Package with complex-workload packages of both sites.
The following example shows configuring the Site Controller Package with complex workload
packages using CFS:
site san_francisco
critical_package sfo_cw
managed_package sfo_cw_dg
managed_package sfo_cw_mp
site san_jose
critical_package sjc_cw
managed_package sjc_cw_dg
managed_package sjc_cw_mp
NOTE:
• Do not add any comments on the same line after specifying critical or managed packages.
• Always set the 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.
2. Apply the Site Controller package configuration.
# cmapplyconf -v -P /etc/cmcluster/cw_sc/cw_sc.config
3. After applying the Site Controller package configuration, run the cmviewcl command to
view the packages that are configured.
Configuring the Metrocluster device group monitor as a service in the Site Controller package
The Device Group Monitor can be configured as a service in the Site Controller Package for SADTA
configurations. For more information on Device Group Monitor configuration, see “Configuring a
Metrocluster package ” (page 26).
The Site Controller Package can be halted in the DETACH mode for maintenance in the Site
Controller Package configuration. The Site Controller Package can also fail in the cluster. In these
conditions, the Device Group Monitoring service is not available for the workloads. The service
resumes once the Site Controller Package is restarted. For more information about the Site Controller
Package and the DETACH mode halt, see “Maintaining Site Controller package” (page 75).
