An alterations-and-attachments review is performed. Changes are made to the equipment that might affect the safe operation of the equipment.
Chapter 2 Using SystemGuard This chapter introduces the SystemGuard service processor which is included in all Symmetric Multiprocessor models. Introduction SMP servers include a service processor, called SystemGuard, as a standard feature. SystemGuard continually monitors the hardware as well as the operating system. If, for instance, a CPU fails, the system detects this, reboots itself automatically and runs the built-in diagnostics on the hardware.
SystemGuard Power SystemGuard has its own DC power boundary. This means that even if the system power is off (power button of the system in the off position), SystemGuard is still powered on, as long as the CPU enclosure still has power. This allows control of the system even though the system is down.
The Operator Panel The Operator Panel is the first level of user interface to SystemGuard. The Operator Panel has the following features: Power button It should generally stay pushed in all the time if you want to be able to power on or off the system remotely.
SystemGuard Consoles SystemGuard works with two types of consoles: The Bump Console , which is an ASCII terminal attached to the S1 serial port. This console provides the normal input to the BUMP. It can be local or remote. The line speed for the BUMP console must be set to 9600 baud for either type of connection.
Init Phase Init phase is entered when the power button on the Operator Panel is pressed on or when the power command is entered on the BUMP Console or Service Console. If the System Key is in Normal mode, the BUMP runs the built-in or resident power-on (PON)-tests on the CPU module hardware, IPLs on the first available processor, runs the functional power on self-tests (POST) on the I/O subsystem to check the system, and finally loads the AIX operating system.
Page 40
Phase Change (Stand-By to Init) The phase change from Stand-By to Init is called Crossing The Power boundary. This is achieved by pushing the power button on the Operator Panel or by typing the keyword power at the Stand-By prompt (>). Note that if you type power while the power button is not pushed in, nothing happens until you press the power button.
Page 41
Power-on (PON) Tests PON tests are run by SystemGuard whenever the system power comes on. There are two types of tests: A comprehensive set of tests are performed on the processors, cache, memory and related hardware when the Fast-IPL flag is disabled. A minimum core set of tests are performed on the processors, cache, memory and related hardware during fast-IPL which cannot be turned off.
Page 42
Enabling at least one processor from the STAND-BY MENU There are other resident PON tests to check other system resources. These tests are a subset of the SystemGuard maintenance offline tests, and reside within the flash EEPROM. These tests are divided into the following groups: BUMP Quick I/O Test Group These tests check the accessibility and the functions of the standard and direct I/O components from the BUMP: Async lines...
Service contract flags These flags enable Service Console usage, maintenance usage and determine if dial-out messages are sent to IBM or to a Customer Service Center. These flags are stored in the SID (System Identification) field of the System EEPROM.
Working with SystemGuard SystemGuard parameters and flags may be changed from different locations. They can be changed from the SystemGuard STAND-BY MENU, the SystemGuard MAINTENANCE MENU, the Diagnostics interface, and also from AIX. When the key signal is received, SystemGuard clears the screen and displays the SystemGuard prompt.
When the system is in Stand-By mode and the System Key (Physical or Electronic Key) is in Service mode, the STAND-BY MENU can be accessed and SystemGuard executed. If you turn the system unit power on from Stand-By mode with the System Key in the Normal position, the system boots to AIX Multi-User.
Page 46
Stand-By Menu The STAND-BY MENU can only be entered when the system is in Stand-By mode (the word Stand-By must be displayed on the LCD display). Perform the following steps to bring up the STAND-BY MENU. 1. With Stand-By displayed on the LCD display press the Enter key on the BUMP console. The Stand-By prompt is the greater than (>) sign.

ECC Memory Component Test This test is identical to the main memory components test but it is applied to the ECC memory components. Error Correction Mechanism Test This test checks the hardware mechanisms enabling the detection of and the correction of single bit errors when working with the main memory.
Interrupt Tests Group These tests are performed by the BUMP as well as the processors. They are launched at Power On and under control of Off Line Test Monitor. They collectively check the interrupt system. The following tests are available under this group. BUMP To CPU Interrupt Test This test is performed jointly by the BUMP and the processor.
CPU MultiProcessor Test Group These tests are launched at Power-On and are also available under the control of the Off Line Tests monitor. These tests check the multi-processor mechanisms, atomic instructions, cache coherency, main memory sharing, and multi-resources sharing. The following tests are available under this group. Atomic Instructions Test This test checks the mechanisms enabling the protection of the content of the memory in case of use of some specific instructions, called “atomic instructions”.

Appendix E. System Power States The state of the system is dependant on the condition of four variable conditions that effect how the system IPLs or shuts down. The four conditions are: the position of the Power-on button This button has two positions. It can be pressed in to the On position (position for turning the power on), or it can be in the out or Off position.
Page 290
If the command sbb is entered on the BUMP console, and the system key is in the Normal position, the system goes to the SBB_ECMD state. If the Power-on button is pressed and changes from the On position to the Off position, the system sets the was_shutdown status to false.
Page 291
If the power_fault status is false, the system attempts to power on. If the system then detects a power fault, the power_fault status is set to true. The system displays an operator panel LCD error message, and the system goes to the MAIN_STANDBY status. If no power fault is detected, the system goes to the IPL state.
Page 292
If the system power does not turn on, the Power-on button may be in the off position. Go to the system unit and press the Power-on button (only press the button once), If the system power still does not turn on there may be an earlier fault condition. Remove main power from the system unit, wait 30 seconds, and restore main power.
