    摘要: A method, system, and computer product for aiding in the debugging of an I/O failure. When an I/O failure is detected on a RIO drawer, a data processing system uses the bulk power controller to provide an alternate path, rather than using the existing RIO links, to access registers on the I/O drawers. The system logs onto the bulk power controller, which provides a communications path between the data processing system and the RIO drawer. The communications path allows the data processing system to read the chip registers on the I/O drawer. The data processing system captures I/O failure information in the I/O drawer using the communications path, wherein the I/O failure information is used to debug the I/O failure.

    摘要: A method, system, and computer usable program product for a self-tuning I/O device are provided in the illustrative embodiments. A change is detected in an adapter communicating with the I/O device, the I/O device being a consolidator configured to communicate with the adapter in a data network. A type of the adapter is determined. Values for each parameter in a set of parameters corresponding to the type of the adapter are determined. The values of a first subset of the parameters are applied to the consolidator, applying the values of the first subset causing the consolidator to be configured to operate in a preferred configuration with the adapter.

    摘要: A method, apparatus, and computer instructions for self-diagnosing remote I/O enclosures with enhanced FRU callouts. When a failure is detected on a RIO drawer, a data processing system uses the bulk power controller to provide an alternate path, rather than using the existing RIO links, to access registers on the I/O drawers. The system logs onto the bulk power controller, which provides a communications path between the data processing system and the RIO drawer. The communications path allows the data processing system to read all of the registers on the I/O drawer. The register information in the I/O drawer is then analyzed to diagnose the I/O failure. Based on the register information, the data processing system identifies a field replacement unit to repair the I/O failure.

    摘要: A non-invasive method, system, and computer product for monitoring I/O performance without using the RIO bus. When executing a performance benchmark run in a remote I/O drawer, the system logs into a bulk power controller, wherein the bulk power controller provides a communications path between the data processing system and the I/O drawer, and wherein the communications path allows the data processing system to access chip register information on the I/O drawer without using a RIO link. Using the communications path, the system may monitor I/O performance and obtain chip register information. The system may further increase performance by using software to detect a load imbalance. Through the communications path, the software is able to dynamically balance the load by changing the chip register settings to allow the initialization registers to handle the load more efficiently.

    摘要: A method, computer program product, and data processing system for analyzing trace data containing bus transactions taking place in packets of varying length is disclosed. A dump of raw trace data from a logic analyzer is stored in a computer file. A computer program then analyzes the raw trace data to identify the locations of packets within the raw trace data. A packet type is determined for each packet, and data fields are extracted from the packet, according to the packet type. A summary of each packet containing the data fields and their contents is then presented to a user.
