No, you can't leave off a fencing device. All nodes need a fencing 
device associated with them. The command-line tool simply enforces this.

You can't. ccs_tool only manages nodes and fencing devices. Because of 
the complexity and variability of services you will have to either edit 
the XML yourself or use one of the GUIs, sorry
