When a Service is available, is it disabled?

11g R2 Solaris 11

2 Node RAC

If I create a service on a two node RAC  and set it as preferred on one node and available on the other node, is the service disabled on the available node? Since the service is stopped and doesn't restart when that server reboots, it acts like it's disabled, but I can't tell. If I run srvctl config service ...... it just says the service is enabled, doesn't specify the status on each node. Also, if you modify the service (srvctl modify service ...) to change the available node to be preferred, does that enable the service and start it
