Using System State Manager › Control Prerequisite Resources

Control Prerequisite Resources

To control prerequisite processing, use the PREMODE, REFMODE, and MODE columns:

PREMODE

Controls whether prerequisite and subrequisite processing is performed for a resource, when DOWN to UP or UP to DOWN transitions occur. The following list describes the valid values for this column:

ACTIVE

Performs both prerequisite and subrequisite processing according to the standard method that SSM uses.

INACTIVE

Performs neither prerequisite or subrequisite processing.

Note: This mode is equivalent to the SSM NOPREREQ mode.

PREREQ

Performs only prerequisite processing for this resource. Subrequisite processing is bypassed.

SUBREQ

Performs only subrequisite processing for this resource. Prerequisite processing is bypassed.

REFMODE

Controls whether other resources process this resource when testing their prerequisite or subrequisite references.

The following list describes the valid values for this column:

ACTIVE

Performs both prerequisite and subrequisite references according to the standard method that SSM uses.

INACTIVE

Evaluates neither prerequisite or subrequisite references to this resource.

Note: This mode is equivalent to the SSM NOPREREQ mode. When you combine REFMODE INACTIVE with PREMODE INACTIVE, this resource disconnects from all prerequisite and subrequisite processing.

PREREQ

Evaluates only prerequisite processing references to this resource. Subrequisite references to this resource are ignored.

SUBREQ

Evaluates only subrequisite processing references to this resource are evaluated. Prerequisite references to this resource are ignored.

MODE

Controls the resource management mode of an individual resource. When you set the MODE column to NOPREREQ, SSM operates as it does in ACTIVE mode, except that it bypasses checking prerequisites or subrequisites.
