COMPUTER COMMAND AND RESPONSE FOR DETERMINING THE STATE OF AN I/O OPERATION
A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predeter...

| description | A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.
Se determina un estado de una operación de entrada/salida (I/O) en un sistema de procesamiento I/O. Una solicitud para llevar a cabo la operación I/O se recibe de un sistema operativo I/O a un subsistema de canales y es reenviada a una unidad de control que controla un dispositivo I/O para ejecutar la operación I/O. Después de que una cantidad de tiempo predeterminada pasa sin recibir la indicación por parte de la unidad de control de que la operación I/O está completada, se recibe una petición de interrogación en el subsistema de canales del sistema operativo I/O para determinar el estado de la operación I/O. Una orden de interrogación es enviada del subsistema de canales a la unidad de control. Se recibe una respuesta de la unidad de control, la respuesta indica un estado del dispositivo I/O que ejecuta la operación I/O, un estado de la unidad de control que controla el dispositivo I/O que ejecuta la operación I/O, y el estado de la operación I/O que se está ejecutando. |
