The Phantom agent enables VCS to determine the state of parallel service groups that do not include OnOff resources.
Do not use the Phantom resource in failover service groups.
Do not attempt manual online or offline operations on the Phantom resource at the resource level. Do not use
hares commands on the Phantom resource at the resource level. Unpredictable behavior results when you try a manual online or offline procedure or an
hares command on a Phantom resource. You can perform commands on the service group that contains the Phantom resource.
