Setting a dependency between the service groups

The RVG service group must be online on both the primary and secondary zones. However, if a failover occurs from one node to another within the same zone, the RVG service group must fail over along with the application service group.

To ensure that the application service group and the RVG service group fail over and switch together from one node to another within the same zone, set up an online local hard dependency between the RVG service group and the application service group. The application service group depends on the RVG service group.

To set up an online local hard dependency

  1. From VCS Cluster Explorer, in the left pane, select the cluster (MYCLUSTER).
  2. In the right pane, select the Service Groups tab.
  3. Click the Link button to create a dependency between service groups.
  4. Click the application service group (the parent service group).
  5. Click the RVG service group (the child resource).
  6. In the Link Service Groups window, do the following, in this order:

    • Select the online local relationship.

    • Select the hard dependency type.

    • Click OK.
