Abstract
The present invention provides a computer implemented method, data processing system and computer program product for running a diagnostic test on an I/O adapter. The data processing system communicates a stop command to a functional device driver; wherein the functional device driver is configured to communicate with the I/O adapter. The data processing system determines whether the functional device driver has completed storing a state of the I/O adapter. The data processing system loads a diagnostic device driver for communicating with the I/O adapter. The data processing system applies test inputs to the diagnostic device driver, wherein at least one test input is presented to the I/O adapter. The data processing system receives test results from the diagnostic device driver.
