failure. At the upper right of the Service Management dialog box, there are three Recovery
Policy options available:

listed that you have configured in Section 5.7, “Adding Cluster Resources”.

If you are adding a Samba-service resource, connect a Samba-service resource directly to
the service, not to a resource within a service. T hat is, at the Service Managem ent
dialog box, use either Create a new resource for this service or Add a
Shared Resource to this service; do not use Attach a new Private
Resource to the Selection or Attach a Shared Resource to the
selection.

resource by clicking on the Attach a new Private Resource to the Selection button.

Resources”. The private resource will appear as a child to the shared resource to which you
associated with the shared resource. Click the triangle icon next to the shared resource to display
any private resources associated.
10. When finished, click OK.
11. Choose File => Save to save the changes to the cluster configuration.
Note
To verify the existence of the IP service resource used in a cluster service, you must use the
/sbin/ip addr list command on a cluster node. T he following output shows the /sbin/ip
addr list command executed on a node running a cluster service:
