Coupling Facility node

 

A Coupling Facility node represents the mainframe computer's coupling facility, the component of the mainframe that enables multiple LPARs to access the same data.

Coupling Facility node lifecycle

The following section describes the scenarios in which a Coupling Facility node is created, updated, or removed.

Creation and update

Coupling Facility nodes are created and updated in exactly the same way as Host nodes.

Removal

A Coupling Facility node can be destroyed either manually or automatically.

To remove a Coupling Facility node manually, find the necessary Coupling Facility, select it in the list and pick Destroy from the Actions list.

Automatic removal happens according to the following scenario.

Coupling Facility nodes are removed when no relationships to MFPart nodes remain.

A Coupling Facility node is also destroyed when its parent mainframe is destroyed. This is a Containment Removal type because a CouplingFacility cannot exist without its mainframe host. See Containment Removal. For information about the destruction of Host nodes, see Host node lifecycle.
