Identifying the Terminal Type to the Diagnostics

When you run diagnostics, you must identify which type of terminal you are using. If the terminal type is not known when the FUNCTION SELECTION menu is displayed, the diagnostics do not allow you to continue until a terminal is selected from the DEFINE TERMINAL option menu.

Undefined Terminal Types

If you specify an undefined terminal type from the DEFINE TERMINAL option menu, the menu prompts the user to enter a valid terminal type. The menu redisplays until either a valid type is entered or you exit the DEFINE TERMINAL option.

Resetting the Terminal

If you enter a terminal type that is valid (according to the DEFINE TERMINAL option menu) but is not the correct type for the Hardware Management Console for pSeries (HMC) virtual terminal window being used, you may be unable to read the screen, use the function keys, or use the Enter key. Bypass these difficulties by pressing Ctrl-C to reset the terminal. The screen display that results from this reset depends on the mode in which the system is being run:

vOnline Normal or Maintenance Mode - The command prompt displays.

vStandalone Mode or Online Service Mode - The terminal type is reset to dumb, the Diagnostic Operating Instruction panel displays, and you are required to go through the DEFINE TERMINAL process again.

Running Online Diagnostics

Consider the following when you run the online diagnostics from a server or a disk:

vThe diagnostics cannot be loaded and run from a disk until the AIX operating system has been installed and configured.

vThe diagnostics cannot be loaded on a system (client) from a server if that system is not set up to boot from a server over a network. When the system is set up to boot from a server, the diagnostics are run in the same manner as they are from disk.

vOn full system partitions, if the diagnostics are loaded from disk or a server, you must shut down the AIX operating system before turning off the system unit to prevent possible damage to disk data. Do this in either of the following ways:

±If the diagnostics were loaded in standalone mode, press the F3 key until DIAGNOSTIC OPERATING INSTRUCTIONS displays. Then press the F3 key once again to shut down the AIX operating system.

±If the diagnostics were loaded in maintenance or concurrent mode, type the shutdown -Fcommand.

vUnder some conditions, the system might stop, with instructions displayed on attached displays and terminals. Follow the instructions to select a console display.

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.
