Chapter 3. 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 still has power. This allows control of the system even though the system is down.
Key Mode Switch (Physical Key) In the 7015 R30, R40, and R50 CPU Enclosures the I/O card contains the NVRAM while the NVRAM battery and the TOD (Time-Of-Day) are located in the Operator Panel. You can drain NVRAM in the following ways:...
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-on 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.
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.
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.
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 EPROM. 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 (S1, S2, and S3), EEPROMs, NVRAM, Flash EPROM, and TOD...
Service contract flags These flags enable Service Console usage, maintenance usage and determine if dial-out messages are to be 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 You can change SystemGuard parameters and flags 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.
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.

Basic Main Memory Test This test is performed by all the processors and it checks the capability to access the main memory in all kinds of data formats. This test applies to one main memory location and the words used during the test are not restored. This test partially checks the DCB ASICs.
Main Memory Components Test This test is performed by all the processors to check all the main memory locations. From the h/w point of view, this test checks the memory chips mounted on the main memory cards. This test can be launched in two modes, as follows: 1.
ECC Data Lines Accessibility Test This test checks the accessiblity for all the data lines to the ECC memory banks, through SMC ASICs. The following h/w parts are checked by running this test. DCB ASICs SMC ASICs Connection of data lines between CPU daughter boards and MPB ASICs Connection of data lines between MPB ASICs and ECC memory chips.
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”.
instruction. This is issued by Processor 0 which is set to Global Copy Back mode. Caching is inhibited for Processor 1. Paradox Detection: DCBST not from Line Owner Here, Processor 1 is set to Local Copy Back mode. Memory coherency is enabled for Processor 0. This test verifies the incoherency introduced by the Local Copy Back.
Main Memory Sharing Test This test is launched by the BUMP and performed by all configured processors. It has a sub-test to check the capability of all the processors to access the main memory. The following h/w parts are checked during the process: 1.
Appendix B. Modifying SystemGuard Parameters Many SystemGuard parameters can be modified in several ways. Some can be modified using the SystemGuard Stand-By menu, others using the SystemGuard Maintenance menu, and others using the AIX diag or mpcfg commands or Diagnostic Service Aids. When you want to modify SystemGuard parameters, the method to use depends on the machine boot phase (stand-by, init, run-time).
Flag, Parameter and Keyword Default Values Name Default Value BUMP Console Power-On Command String Power Service Console Power-On Command String Blank (not set) BUMP Console Power-On Command flag Enabled Service Console Power-On Command flag Disabled Remote Authorization flag Disabled Autoservice IPL flag Disabled BUMP Console Present flag Enabled...
Changing Flags and Parameters Under AIX Service Aids The Service Aids are recommended to change the flags. The Service Aids can be entered using the diag command or by booting diagnostics in service mode. They display or change flag values using 0 (zero) for disabled and 1 (one) for enabled. The explanations that follow refer to the Service Aids.
SystemGuard Maintenance Menu Starting from the main maintenance menu: Enter 2 to enable the flag. Enter 3 to disable the flag. AIX Diag Command Starting from the Service Aids Selection menu: 1. Select the BUMP Service Aids option. 2. Select the Display or Change Flags and Configuration option. 3.

Diagnostic Load Progress Indicators The following dump progress indicators, or dump status codes, are part of a Type 102 message. Note: When a lowercase c is listed, it displays in the lower half of the seven-segment character position. The leftmost position is blank on the following codes. The dump completed successfully.
Appendix F. System Power States The state of the system is dependant on the condition of four variable conditions that effect how the system IPLs or shutsdown. 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.
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.
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.
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.
