Abstract
A system and method for testing I/O components without requiring initiation of the test I/O requests from the operating system via the instruction stream. An I/O system facilitates I/O operations between a processing system and I/O devices during normal I/O processing. An exerciser initiation queue is established, which corresponds to an operating initiation queue used during normal I/O processing. The I/O system is configured to monitor for test I/O requests on the exerciser initiation queue in lieu of monitoring for standard I/O requests on the operating initiation queue. A testing module enters the test I/O requests on the exerciser initiation queue in a format analogous to standard I/O requests entered on the operating initiation queue during normal I/O processing. The test I/O requests on the exerciser initiation queue are processed via the I/O system. Upon I/O completion, status may be returned to the testing module for processing of test results.
