Abstract
Examples of techniques for transparent north port recovery of an error in an input/output device are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method may include: detecting, by a processing device, a command timeout; sending, by the processing device, an input/output (I/O) error signal to a host processing system connected to the hardware device via a north port of the hardware device; terminating, by the host processing system, a link between the north port of the hardware device and the host processing system; enabling, by the processing device, halt command forwarding on the hardware device; halting, by the processing device, commands upon detecting the halt command forwarding; and resetting, by the processing device, the link between the north port of the hardware device and the host processing system.
