Displays error conditions detected by the service processor. Refer to ªService Processor Error Logsº on page 60 for an example of this error log.

vRead System POST Errors

This option should only be used by service personnel to obtain additional debug information.

vRead NVRAM

Displays Non Volatile Random Access Memory (NVRAM) content.

vRead Service Processor Configuration Displays current service processor configuration.

vProcessor Configuration/Deconfiguration Menu

Enable/Disable CPU Repeat Gard

CPU repeat gard automatically deconfigures a CPU during a system boot if a processor has failed BIST POST, caused a machine check or check stop, or has reached a threshold of recoverable errors. The processor will remain deconfigured until repeat gard is disabled or the processor is replaced.

Repeat gard is enabled by default.

For more information, see ªConfiguring and Deconfiguring Processors or Memoryº on page 55.

Enable/Disable Dynamic Processor Sparing

This option is part of the Capacity Upgrade on Demand (CUoD) function. Dynamic Processor Sparing is the capability of the system to deconfigure a failing (or potentially failing) processor and then configure a replacement processor from the unlicensed CUoD processor pool.

If the system is running logical partitions, the hot sparing operation takes place while the system is running. If the system is booted in a full system partition, the system must be rebooted for the processor sparing operation to take place.

Processor hot sparing is enabled by default.

Note: The memory affinity of the failing processor is not taken into account when the replacement processor is assigned; the replacement processor is the next processor that is available.

This menu allows the user to change the system processor configuration. If it is necessary to take one of the processors offline, use this menu to deconfigure the processor, and then reconfigure the processor at a later time. An example of this menu follows:

pSeries690 specifications

The IBM pSeries690, also known as the IBM eServer p690, is a high-performance server within IBM's line of Power Systems, designed primarily for enterprise-level workloads. Launched in the early 2000s, it distinguished itself as one of IBM's flagship offerings, aimed at delivering exceptional scalability, reliability, and processing power.

At the heart of the pSeries690 is the IBM POWER4 processor, a revolutionary architecture that significantly enhanced processing capabilities. The system supports multiple processor configurations, allowing businesses to customize performance based on their specific applications. Each pSeries690 can be configured with up to 32 POWER4 processors, providing a maximum processing power that is well-suited for demanding enterprise applications, complex databases, and large-scale transaction processing.

One of the standout features of the pSeries690 is its ability to handle massive amounts of memory — up to 1TB of total RAM. This is particularly advantageous for businesses that run memory-intensive applications or require high availability for critical tasks. The server’s advanced memory architecture contributes to faster data access and improved overall system performance.

Additionally, the IBM pSeries690 employs the innovative AIX operating system, which is tailored for high performance and reliability. AIX comes equipped with features such as dynamic logical partitioning (LPAR), allowing resources to be allocated flexibly and efficiently across different workloads. This technology supports virtualization, enabling multiple operating environments to run concurrently on a single physical server, optimizing resource utilization.

The pSeries690 also includes robust fault tolerance and reliability features. Redundant components, hot-swappable parts, and advanced error detection mechanisms ensure that the system remains operational even in the event of hardware failures. This reliability is crucial for mission-critical applications where downtime can lead to substantial financial losses.

Networking capabilities of the pSeries690 are enhanced by support for high-speed connections, including Gigabit Ethernet and the ability to integrate with various network topologies. This versatility facilitates seamless connectivity in complex IT environments.

In conclusion, the IBM pSeries690 remains a powerful and reliable choice for enterprises seeking to manage and optimize their most demanding workloads. Its combination of cutting-edge processing capabilities, expansive memory support, and robust virtualization features makes it a significant player in the realm of enterprise computing. As businesses continue to evolve, the core strengths of the pSeries690, especially in terms of scalability and reliability, ensure that it continues to meet the needs of demanding applications.
