Switch supervisor communications (MAP 0595)

Step 0595-006

The supervisor self-test failed because the yellow LED flashed the wrong address.

1.Make certain that the correct supervisor harness connector is plugged into the supervisor.

2.Is the correct harness plugged in?

vIf yes, go to the Start MAP (0100) in the RS/6000 SP: System Service Guide and troubleshoot the supervisory bus system.

vIf no:

a.Plug in the correct supervisor connector.

b.Return to ªStep 0590-002º on page 1-4 and confirm the original conditions.

Step 0595-007

The supervisor self-test failed because the yellow LED was on steady. This indicates that the supervisor is operating with base code only and needs to have the correct application code loaded.

Note: If the replacement supervisor card is new or it has the wrong application code, the self-test will fail at the last step and the yellow LED will remain on.

1.Perform the SP Switch2 Base code verification procedure on 3-8.

2.Based on the information returned from the Base code verification, perform the procedure for ªUpdating the SP Switch2 supervisor codeº on page 3-8.

3.After updating the supervisor code, perform the ªSP Switch2 supervisor self-testº on page 3-6.

4.Does the supervisor pass the self-test? v If yes, go to ªStep 0595-010º.

vIf no, go to the Start MAP (0100) in the RS/6000 SP: System Service Guide and troubleshoot the supervisory bus system.

Step 0595-008

You replaced an SP Switch2 supervisor card.

1.Reconnect the supervisor harness to the connector at the back of the SP Switch2. v Reconnecting the harness initiates the supervisor self-test.

2.Do the green and yellow LEDs light? v If yes, go to ªStep 0595-009º.

v If no, go to the Start MAP (0100) in the RS/6000 SP: System Service Guide and troubleshoot the supervisory bus system.

Step 0595-009

You replaced a supervisor card and the green and yellow LEDs lit during the self-test.

1.Rerun the ªSP Switch2 supervisor self-testº on page 3-6.

v While the test is running, compare the LED conditions on the supervisor with those listed in the ″Self-test Conditions″ table.

2.Did the supervisor pass the self-test?

v If yes, go to ªStep 0595-002º on page 1-7. v If no, go to ªStep 0595-003º on page 1-7.

Step 0595-010

1.Refresh Perspectives

2.Power on the switch.

3.Does Perspectives indicate that the problem is still present?

v If yes, return to the Start MAP (0100) in the RS/6000 SP: System Service Guide.

vIf no, go to the End of call procedures (MAP 0650) in the RS/6000 SP: System Service Guide.

RS/6000 SP specifications

The IBM RS/6000 SP (Scalable Power) is a high-performance computing system that was developed in the early 1990s and has since become a significant player in the realm of supercomputing and enterprise solutions. Designed primarily for scientific, engineering, and complex data analysis tasks, the RS/6000 SP provides powerful processing capabilities, enhanced scalability, and features to support demanding applications.

One of the key characteristics of the RS/6000 SP is its modular architecture, which allows for the addition of multiple nodes. Each node is based on IBM's Power architecture, leveraging the RISC (Reduced Instruction Set Computing) design to achieve high throughput and efficiency. The system can support configurations ranging from a few nodes to hundreds, enabling organizations to scale their computational power as needed based on workload requirements.

The RS/6000 SP employs advanced interconnect technologies, most notably the SP Switch, which ensures high-speed communication between nodes. This interconnect allows for seamless data transfer, ensuring that the system can handle large datasets and complex computations without bottlenecks. The SP's ability to deliver concurrent processing capabilities makes it ideal for parallel computing tasks, including simulations, modeling, and large-scale computations.

In terms of software, the RS/6000 SP was equipped with AIX, IBM's version of the UNIX operating system, which provides a stable and secure environment for enterprise applications. Furthermore, the system supports a vast array of programming languages and tools, including Fortran, C, and C++, along with libraries and frameworks designed for high-performance computing. This compatibility allows developers to optimize their applications to fully utilize the underlying hardware.

Another notable feature of the RS/6000 SP is its extensive support for various workloads, including database management, multi-user applications, and graphical processing. The system was equipped with high-performance graphics capabilities, making it suitable for tasks that require intensive visualization, such as computer-aided design (CAD) and scientific visualization.

Overall, the IBM RS/6000 SP has solidified its role in the high-performance computing landscape, combining advanced technologies, robust scalability, and flexibility to meet the unique demands of research and enterprise environments. Its legacy continues to influence modern computing architectures, embodying IBM’s commitment to innovation and performance in the pursuit of complex problem-solving capabilities.
