19. Validate the changes done by running:
cmcheckconf -v -P <pkg_ascii_file>
20. Edit the package configuration file to add the generic resource parameters.
21. Validate the changes done by running:
cmcheckconf -v -P <pkg_ascii_file>
22. Apply the changes by running:
cmapplyconf -v -P <pkg_ascii_file>
23. Start the package.
Example of Migration of an EMS Resource to a Generic Resource
Let us consider an example of an EMS resource /vg/vgpkg/pv_summary that monitors the status
of all PV links for the volume group vgpkg.
• Consider a package pkg1 that is configured with the following EMS resource parameters:
resource_name /vg/vgpkg/pv_summary
resource_polling_interval 60
resource_start DEFERRED
resource_up_value = UP
• Identify the equivalent SFM style resource monitor.
• Create a monitoring script (e.g., sample_generic_resource_disk_monitor.sh)
containing the logic to monitor the resource. Configured this script as a service by providing
the full path name of the script in the service_cmd parameter and associating it to a
service_name (e.g., sfm_vg_monitor) as follows:
service_name sfm_vg_monitor
service_cmd /etc/cmcluster/pkg1/sample_generic_resource_disk_monitor.sh
NOTE: You can also configure other 'service' parameters, but these are optional.
• If not already available, obtain a copy of the package's configuration file by running:
cmgetconf -v -p pkg1 pkg1.conf
• Edit the package configuration file by removing the EMS resource (mentioned above) from
the package.
• Configure a generic resource as follows:
service_name sfm_vg_monitor
service_cmd /etc/cmcluster/pkg1/sample_generic_resource_disk_monitor.sh
generic_resource_name sfm_vg
generic_resource_evaluation_type during_package_start
NOTE: Since the EMS monitor is of type DEFERRED, configure the generic resource with
evaluation type as during_package_start.
• Validate the changes done by running:
cmcheckconf -v -P pkg1.conf
• Apply the changes by running:
cmapplyconf -v -P pkg1.conf
• Start the package.
• Verify that the generic resource parameters are configured by running:
cmviewcl -v -p pkg1.conf
IMPORTANT: If you are migrating an EMS resource of type DEFERRED (as shown in the example),
you can edit the parameters online, i.e., without halting the package. Since this is an online
operation, it is recommended that you be cautious while editing the required parameters.
