+ Multiple nodenames are separated by colon (:)

+ -s service addresses the IP addresses to failover
+ Multiple addresses are separated by colon (:)

+ -c heartbeat channel the method to send/rcv heartbeats on
+ The default method is multicast, and multicast_
+ ipaddress is "225.0.0.11".
+ -o heartbeat options a "catchall" for other heartbeat configuration
+ options
+ Multiple options are separated by colon (:)

+ -v verbose mode
+ -d target device the target device name and mount point
+ The device name and mount point are separated by
