How to change the order that scripts and other resources are called for a clustered service in Red Hat Enterprise Linux with High-availability

Issue

• What do parent, child, and sibling relationships mean for cluster resources configured for a service?
• How can I change the order that scripts and other resources are called for a clustered service?
• How can I make sure scripts are called in a certain order for a clustered service?
• Cluster service not able to relocate due to resource dependencies not configured in correct order.
• In looking at example configurations, I see a hierarchy in the XML for clustered resources under a service. What does that hierarchy mean?

<service name="my_service" ...>
    <ip address="10.1.1.2" .../>
    <fs name="my_filesystem" ...>
        <script name="my_script"/>
    </fs>
</service>
