Operators who must respond to hot I/O conditions should try to solve the problem at the lowest possible level; that is, they should try to correct the problem at the device first, and then the control unit. Operators can power the device off and on. If that does not help, they can reset the control unit if the affected device is not a direct access device. If these actions do not correct the problem, they might have to physically disconnect the device or control unit.

Whatever action operators take, they must respond to the prompting message or restartable wait state.
