Uninitialized

Uninitialized

Description: Switch adapter has not been initialized.

 

 

 

Processor node may not recognize adapter due to hardware

 

 

 

failure or bad software configuration.

 

 

 

Action:

 

 

 

1. If there are any other errors in the

 

 

 

/var/adm/SPlogs/css0/p0/out.top file on the primary

 

 

 

node, address those errors first.

 

 

 

Note: If the problem is on all nodes in the frame, check

 

 

 

for any hardware problems with the switch assembly.

 

 

 

Also check for switch-to-switch problems on all jacks of

 

 

 

the switch assembly.

 

 

 

2. If all the nodes are uninitialized except for the primary

 

 

 

node, verify that the primary node is connected to the

 

 

 

correct port.

 

 

 

3. Have customer verify that the correct switch software is

 

 

 

installed and running on the problem node. rc.switch

 

 

 

starts the fault_service_Worm_RTG_CS daemon.

 

 

 

Note:

 

 

 

v If the daemon starts, go to 6

 

 

 

v If the daemon does not start, go to 4

 

 

 

v When working with a two-plane SP Switch2 system,

 

 

 

add the adapter name to the command, as follows:

 

 

 

rc.switch -a<adapter_name>

 

 

 

4. If you:

 

 

 

v Are not certain that the problem is hardware related,

 

 

 

go to the Parallel System Support Programs for AIX:

 

 

 

Diagnosis Guide (GA22-7350)

 

 

 

v Are certain that you have a hardware problem, go to 5

 

 

 

5. If you get no result, try swapping in another switch

 

 

 

adapter. Repeat step 3. If you get a result, the problem

 

 

 

is probably resolved; repeat ªStep 0620-001ºon

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.
