H A Ddriver-model.rst272 and are called 'chp0.<chpid>'. They have no driver and do not belong to any bus.
280 Piping 'on' or 'off' sets the chpid logically online/offline.
281 Piping 'on' to an online chpid triggers path reprobing for all devices
282 the chpid connects to. This can be used to force the kernel to re-use
