$0 manages an ICP Vortex clustered host drive.
The 'start' operation reserves the given host drive.
The 'stop' operation releses the given host drive.
The 'status' operation reports whether the host drive is reserved.
The 'monitor' operation reports whether the host drive is reserved.
The 'validate-all' operation reports whether OCF instance parameters are valid.
The 'methods' operation reports on the methods $0 supports
