partitions. A reboot is required on the partition containing this device and on the moved device, but the system itself is not powered off in order to boot standalone diagnostics in a logically partitioned system..

Considerations for Running Standalone Diagnostics from CD-ROM

Consider the following when you run standalone diagnostics:

vThe diagnostic CD must remain in the CD-ROM drive for the entire time that diagnostics are running.

vThe diagnostic CD cannot be ejected from the CD-ROM drive after the diagnostics have loaded. The CD can only be ejected after the system has been turned off and then turned on (standalone mode) or after the diagnostics program has terminated (online concurrent mode).

vThe CD-ROM drive from which diagnostics were loaded cannot be tested.

vThe SCSI adapter (or circuitry) controlling the CD-ROM drive from which diagnostics were loaded cannot be tested.

Loading the Standalone Diagnostics from CD-ROM

To run standalone diagnostics in service mode from CD-ROM, do the following:

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

2.Remove all tapes, diskettes, and CD-ROMs.

3.Power off the pSeries 690 (see the IBM Hardware Management Console for pSeries Installation and Operations Guide, order number SA38-0590, for more information about full system partitions).

4.Right-click the mouse and select Open Terminal Window.

5.From the service processor menu on the VTERM, select option 2, System Power Control Menu.

6.Select option 6. Verify that the state changes to currently disabled. Disabling fast system boot automatically enables slow boot.

7.Select option 98 to exit the system power control menu.

8.Use the HMC to power on the managed server in a full system partition. Select the Power on Diagnostic Default Boot List.

9.Insert the CD-ROM into the CD-ROM drive in the media subsystem in the pSeries 690 (not into the HMC's CD-ROM drive).

Running Standalone Diagnostics from a Network Installation Management (NIM) Server

A client system connected to a network with a Network Installation Management (NIM) server can boot standalone diagnostics from the NIM server if the client-specific settings on both the NIM server and client are correct.

Notes:

1.All operations to configure the NIM server require root user authority.

2.If you replace the network adapter in the client, the network adapter hardware address settings for the client must be updated on the NIM server.

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.
