Adding Service Model component relationships

Use the Services Editor tab to add relationships between the service model components that you create in the administration console.

To add a Service Model component relationship

  1. Open a component relationships pane in the Services Editor tab by using one of the following methods:
    • On the navigation pane, select the component. 
    • On the navigation pane or from Results, right-click a component and select View Service Model.
    • Drag and drop the component from either the navigation pane or Results onto the relationships pane.
  2. On the Services Editor tab navigation pane or from Results, right-click a component and select Add Relationship.
  3. In the Find Service Components pane, select a data class from the Class list.
  4. In the Name Contains field, enter a comparison value.
  5. If you want the priority to be propagated to the causal components, select Propagates priority.
  6. Select the In SLM Agreement check box if required.
  7. Click Find.
    All components matching the search criteria appear in the Results pane.
  8. From the Results pane, select the appropriate component and click OK.
  9. Optionally, instead of steps 2 to 8, drag and drop the component from either the navigation pane or Results into the relationships pane on the component to which you want to add the relationship to.
  10. In the Edit Relationships dialog box, specify which component should be the consumer and which component should be the provider by selecting the required arrow direction.
  11. Specify the type of relationship:
    • Direct, Increasing, or Decreasing 
      • Direct-the status of the consumer component might be identical to that of its provider component, depending on the events directly affecting the consumer's status, which is also taken into account. 
      • Decreasing-the status of the consumer component is less critical than that of the provider component by one level. For example, if the provider status is WARNING, the consumer status is INFO. 
      • Increasing-the status of the consumer component becomes more critical than that of its provider component by one level. For example, if the provider status is WARNING, the consumer status is MINOR. 
    • Active or Inactive 
      • Active-An active relationship is an impact relationship and indicates that the status of the consumer instance depends in some measure on the status of the connected provider instance. 
      • Inactive-An inactive relationship means that no dependency exists or that the dependency is irrelevant to the model. The components are only logically and visually linked.
  12. In the Status Weight field, accept the default value or enter a number for the consumer object. (Status weight is used in the WEIGHTED_CLUSTER status computation model. For more information about component status computation see How component status computation works.
  13. Optionally, in Description, type a description for the relationship. The default description changes based on the relationship type that you select as follows:
    • DIRECT relationship (linear impact) 
    • DECREASING relationship (reducing impact) 
    • INCREASING relationship (increasing impact)
  14. Click Apply and click OK.

    Note

    To be able to add a relationship between two components from two different cells, you must create an entry of both the cells in the mcell.dir file for both the cells and then restart these two cells.
