Managing HP Serviceguard for Linux, Tenth Edition, September 2012

Using Serviceguard Command to Get the Status/Value of a Simple/Extended Generic Resource
Use the cmgetresource command to get the status of a simple generic resource or the
value of an extended generic resource. For example:
cmgetresource -r sfm_disk
This retrieves the status of the generic resource sfm_disk if it is configured as a simple
resource. If configured as an extended resource, the value is returned.
Using Serviceguard Command to Set the Status/Value of a Simple/Extended Generic Resource
Use the cmsetresource command to set the status of a simple generic resource or the
value of an extended generic resource. For example:
cmsetresource -r sfm_disk -s up
This sets the status of the generic resource sfm_disk to up. This is a simple generic
resource and only the status can be set to up/down.
cmsetresource -r sfm_lan 10
This sets the current value of the generic resource sfm_lan to 10. This is an extended
generic resource and only numeric values from 1 to 2147483647 can be set.
See the man pages for more information.
Online Reconfiguration of Generic Resources
Online operations such as addition, deletion, and modification of generic resources in
packages are supported. The operations that can be performed online are:
• Addition of a generic resource of generic_resource_evaluation_type set
to during_package_start, if the status of the generic resource is not 'down'.
Please ensure that while adding a generic resource, the equivalent monitor is
available; if not add the monitor while adding a generic resource.
• Addition of a generic resource of generic_resource_evaluation_type set
to before_package_start, whose status is 'up'.
• Deletion of a generic resource. Please ensure that while deleting a generic resource,
the equivalent monitor is also removed. However, if a common resource is being
monitored across multiple packages, then before removing the monitor ensure that
the generic resource being deleted is not configured in other packages that are also
using this monitor.
• Modification of generic_resource_evaluation_type from
before_package_start to during_package_start or vice versa when the
resource is 'up'.
• Modification of generic_resource_up_criteria specified for resources of
evaluation type before_package_start or during_package_start provided
