IBM RS/6000 SP manual Running diagnostics on a switch port

Page 70

9. On the control workstation, set the node to boot from disk. For example:

spbootins -r disk 2 12 1

10.On the control workstation, use Perspectives to power off the node and then power it back on. The node will now boot from the device that you specified in step 7 with the correct time.

Running diagnostics on a switch port

Attention: Servicing a processor node or switch assembly may interrupt customer usage of the processor node and the remainder of the switch network. If the switch feature must be replaced in a multi-frame system, refer to ªRemoving and restoring switch resourcesº on page 3-9, for information on isolating the switch assembly.

Before running diagnostic tests on a switch to diagnose node to switch problems, you must identify the port number. For example:

Bulkhead jack 6 on switch 17 frame 1 is identified as E01-S17-BH-J6

To run the test from the control workstation for this example the syntax of the command is:

/usr/lpp/ssp/bin/spd/wrap_test -j E01-S17-BH-J6

The wrap test will indicate when to use the following items that are supplied as part of the ship group:

vWrap cable

vWrap plug

vInterposer wrap card

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.
