which new command about start/stop sentinel service after upgrade 8.6.1

Hi All

     I try upgrade 8.6.1 to my sednitnle appliance server...it seem upgrade well.

but I find a different before uprade that I could not use original command to stop/start sentinel service.

at/before sentinel 8.6.0 , I could use rcsentinel stop/start service.

but at 8.6.1....it cold not use this command.

whether this command change to another new command  ?

Thanks!!
