When you define your resources it is time to define group service you will run. Click on Service Group tab and click on Add button. Define service name, choose to start it automatically and which failover domain you will prefer. Click on submit.

Now you have to add resources to your service. Click to Add resources button. First you will choose IP address you already defined, then click on Add Child Resources and choose your HA LVM defined. In that prompt click on Add Child Resources and choose mount point. Again click on Add Child Resources and choose oracle resource. As you probably noticed all resources are nested one-by-one. On this way you are sure that resources will be relocated to another node. When you are finished click on Submit. You will probably get something like this.
