3.8. Adding a Cluster Service to the Cluster

To add a cluster service to the cluster, follow these steps:

  1. Select the Services property and click the Create a Service button. The Add a Service dialog is displayed as shown in Figure 3-10.

    Figure 3-10. Adding a Cluster Service

    Give the cluster service a descriptive name to distinguish its functionality relative to other services that may run on the cluster.

  2. If you want to restrict the members on which this cluster service is able to run, choose a failover domain from the Failover Domain drop-down. (Refer to Section 3.6 Configuring a Failover Domain for instructions on how to configure a failover domain.)

  3. Click the Add a Shared Resource to this service and choose the a resource listed that you have configured in Section 3.7 Adding Cluster Resources.

  4. If needed, you may also create a private resource that you can create that becomes a subordinate resource by clicking on the Attach a new Private Resource to the Selection button. The process is the same as creating a shared resource described in Section 3.7 Adding Cluster 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.

  5. When finished, click OK.

  6. Choose File => Save to save the changes to the cluster configuration.

NoteNote
 

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. The following output shows the /sbin/ip addr list command executed on a node running a cluster service:

1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1356 qdisc pfifo_fast qlen 1000
    link/ether 00:05:5d:9a:d8:91 brd ff:ff:ff:ff:ff:ff
    inet 10.11.4.31/22 brd 10.11.7.255 scope global eth0
    inet6 fe80::205:5dff:fe9a:d891/64 scope link
       valid_lft forever preferred_lft forever
