Configuring dependencies for a virtual business service

For a selected virtual business service, you can configure the order in which its constituent service groups are brought online (during virtual business service start operation) and taken offline (during virtual business service stop operation).

You can establish a service group's relationships with its child service groups. For the service groups that are configured on virtual machines, you can also enable virtual machine auto-start and auto-stop options. It ensures that if the virtual machine is detected as turned off during virtual business service start operation, Veritas Operations Manager turns it on, and brings the service group online on that virtual machine. Similarly, if you have selected virtual machine auto-stop option, after the service group is taken offline, Veritas Operations Manager turns off that virtual machine. The start and stop operations apply only to the single node clusters that are part of the selected virtual business service.

Note:

Virtual business service does not alter the dependencies that are set through Symantec Cluster Server.

To perform this task, your user group must be assigned the Admin role on the service group or the Availability perspective. The permission on the service group may be explicitly assigned or inherited from a parent Organization or cluster.

Caution:

Do not create cyclic dependencies across clusters in a virtual business service, as it is not supported in VBS.

To configure dependencies in a virtual business service

  1. In the Management Server console, go to the Availability perspective and expand Manage in the left pane.
  2. Select Data Center in the navigation tree.
  3. Select the Virtual Business Services node.
  4. In the virtual business services list, right-click on the required virtual business service and select Configure dependencies.
  5. In the Configure Virtual Business Service dependencies - Specify service group dependencies panel options wizard panel, under Parent, select the parent service group from the drop-down list. Under Child, select the child service group that you want to associate with the selected parent service group. Select the type of dependency from the drop-down list and click Link. Click OK. By default, the type of dependency is set to soft.

    See Configure Virtual Business Service dependencies - Specify service group dependencies panel options.

  6. In the Configure Virtual Business Service dependencies - Specify VMs start or stop wizard panel, select the service group for which you want to enable virtual machine auto-start and auto-stop option.

    See Configure Virtual Business Service dependencies - Specify VMs start or stop panel options.

  7. Use the Specify Script Execution details wizard panel to define and execute custom scripts. Custom scripts can be defined only if the dependency type is Soft.

    See Specify Script Execution details panel options.

  8. In the Result wizard panel, verify the configuration that you have made for selected virtual business service.

    Note:

    In a VBS that has one of the tier configured for a global service group, VBS daemons across tiers communicate using the virtual IP address set in the ClusterAddress attribute of the global service group tier.

  9. Click Finish.

Note:

If the virtual business service contains a mix of local and global service groups, and one or more global service groups are in online or partial state on a remote reachable cluster (which is in running state), then virtual business service start operation is rejected. For such a virtual business service, you need to manually take all the global service groups on the remote clusters offline, and then bring virtual business service at the local site online.
