usage: $0 (start|stop|validate-all|meta-data|help|usage|monitor)
$0 manages a Oracle ASM Disk Group as an OCF HA resource.
The 'start' operation starts the instance.
The 'stop' operation stops the instance.
The 'status' operation reports whether the instance is running
The 'monitor' operation reports whether the instance seems to be working
The 'validate-all' operation reports whether the parameters are valid
