• generic_resource_name: defines the logical name used to identify a generic resource in
a package.
• generic_resource_evaluation_type: defines when the status of a generic resource
is evaluated. This can be set to during_package_start or before_package_start.
If not specified, DPS is considered as default.
◦ during_package_start means the status of generic resources are evaluated during
the course of start of the package.
◦ before_package_start means resource monitoring must be started before the package
start and all the configured resources must be UP on a given node for the package to be
started on that node.
• generic_resource_up_criteria: defines a criterion to determine the 'up' condition for
a generic resource. It also determines whether a generic resource is a simple resource or an
extended resource. This parameter requires an operator and a value. The operators ==, !=,
>, <, >=, and <= are allowed. Values must be positive integer values ranging from 1 to
2147483647.
The following is an example of how to configure simple and extended resources.
Simple generic resource:
generic_resource_name sfm_disk
generic_resource_evaluation_type before_package_start
Extended generic resource:
generic_resource_name cpu_lan
generic_resource_evaluation_type during_package_start
generic_resource_up_criteria <50
For more information on the generic resource parameters, see “Package Parameter Explanations”
(page 168).
4.8.6 Configuring a Generic Resource
This section describes the step-by-step procedure to configure generic resources. You can also
configure generic resources from Serviceguard Manager. See the online help for instructions on
how to configure from Serviceguard Manager.
1. Create a package configuration file that contains the generic resource module:
cmmakepkg $SGCONF/pkg1/pkg1.conf
Package template is created.
This file must be edited before it can be used.
NOTE: To generate a configuration file adding the generic resource module to an existing
package (enter the command all on one line):
cmmakepkg -i $SGCONF/pkg1/pkg1.conf -m sg/generic_resource
2. Edit the package configuration file and specify the generic resource parameters (as shown in
the snippet):
service_name cpu_monitor
service_cmd $SGCONF/generic_resource_monitors/cpu_monitor.sh
service_halt_timeout 10
generic_resource_name sfm_cpu
generic_resource_evaluation_type during_package_start
