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.

Method and apparatus for device driver state storage during diagnostic phase

A method, apparatus, and computer instructions for handling updates. A database is queried to determine an effect of the update on the data processing system in response to detecting an update for the data processing system. A configuration of the data processing system is used in querying the database. A health status of the data processing system is selectively modified using the response to form a modified health status in response to receiving a response from the database.

Intelligent system health indicator

A plurality of data packets encoded according to a first protocol are received which encapsulate data encoded according to a second protocol. A first source address is extracted from the packets according to the first protocol, it is determined whether or not the first source address is a substantial duplicate of a known assigned address. If it is a duplicate, a second source address is extracted from the encapsulated data according to the second protocol, and the first source address and said second source address are provided in an enhanced error log so that a system administrator may correct the duplicate assigned address. Enhanced embodiments of the invention included analysis of data encapsulated by a third, fourth and subsequent protocols, and automatic determination of each protocol encoding format.
