When you enable a disabled service, that service is started and
becomes available on the specified cluster member. (You can start the
service on another member by dragging the service icon into the Members tab of the
Cluster Status Tool and dropping the icon on
the member icon
.)
To enable a stopped service, invoke the redhat-config-cluster command to display the Cluster Configuration Tool. In the Services tab, select the service you want to enable and click Enable.
