Many peripheral subsystems require host intervention for recovery from device errors and control unit errors. In a control unit having a data buffer, the operation of the devices and the operation of the processes in the host may be highly asynchronous; therefore, the timing of any error interrupt may or may not have an operational relationship between the reporting of the error and the execution of the process. Further, a plurality of errors may occur before an error recovery has been abandoned or successfully completed.
