Chapter 7. Verifying the Hardware Operation

The system verification procedure checks the system for correct hardware operation. Run the system verification procedure as described in the following steps.

If you are analyzing a hardware problem, see Chapter 8, ªHardware Problem

Determinationº on page 145.

Step 1. Considerations Before Running This Procedure

Read the following before using this procedure:

vThe AIX operating system must be installed on your system before you attempt to perform this procedure.

vIf this system unit is directly attached to another system unit or attached to a network, be sure communications with the other systems are stopped.

vThis procedure requires use of all of the system resources. No other activity can be running on the system while you are performing this procedure.

vThis procedure requires an Hardware Management Console for pSeries (HMC) attached to the HMC port on the pSeries 690.

vThis procedure runs the AIX online diagnostics in service mode on a full system partition.

Does the system have AIX diagnostics preinstalled?

YES

Go to ªStep 2. Loading the Online Diagnostics in Service Modeº.

NO

Go to ªStep 2.5 Loading the Standalone Diagnostics from CD-ROMº

 

on page 142.

Step 2. Loading the Online Diagnostics in Service Mode

To run the online diagnostics in service mode from the boot hard disk, do the following:

1.Stop all programs including the AIX operating system (get help if needed).

2.Remove all tapes, diskettes, and CD-ROM discs.

3.Power off the managed system (refer to Full System Management Tasks in the IBM Hardware Management Console for pSeries Installation and Operations Guide).

4.Use the HMC to power on the managed system in full system partition mode. Select the Power on Diagnostic Stored Boot List option (see the IBM Hardware Management Console for pSeries Installation and Operations Guide for more information about full system partitions).

5.Enter any requested password.

Note: If you are unable to load the diagnostics to the point when the DIAGNOSTIC OPERATING INSTRUCTIONS display, call your support center for assistance.

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.
