Data Integrity and Verification
IBM computer systems contain mechanisms designed to reduce the possibility of
undetected data corruption or loss. This risk, however, cannot be eliminated. Users who
experience unplanned outages, system failures, power fluctuations or outages, or
component failures must verify the accuracy of operations performed and data saved or
transmitted by the system at or near the time of the outage or failure. In addition, users
must establish procedures to ensure that there is independent data verification before
relying on such data in sensitive or critical operations. Users should periodically check
the IBM support websites for updated information and fixes applicable to the system and
related software.

Powering the System On and Off
The system can be powered on after the following cables are connected:
v V/S COMM Cable
v All RIO cables
v All SPCN cables
v JTAG Cable
v All PCI cables to supported drawers
4 Service Guide
After the required cables are installed, and the power cables are connected, the power
button on the primary I/O drawer operator panel can be pushed to initialize the system.
Progress indicators, also referred to as checkpoints, are visible on the primary I/O
drawer operator panel display and the power LED on the primary I/O drawer stops
blinking and stays on, indicating the system power is on.
The CEC drawer and secondary I/O drawers are powered on through the primary I/O
drawer system power control network (SPCN). When power is applied, the power LEDs
on the CEC drawer and primary I/O drawer go from blinking to on continuously, and the
power LED on the secondary I/O drawer comes on and stays on. This indicates that
power levels are satisfactory in the drawers.
If the system is operating under AIX, type the shutdown command to power off the
system. If you cannot use this method, you can power off the system by pressing the
primary I/O drawer operator-panel power button.
Attention: Using the operator-panel power pushbutton to power off the system can
cause unpredictable results in the data files, and the next IPL will take longer to
complete.
For complete details on how to power on and off the system, go to “Powering Off and
Powering On the System” on page 427 and “System Power-On Methods” on page 397.
Console Strategy
The firmware starts a console-selection sequence at system boot time if any of the
following is true:
v A console has not yet been selected.
v A previous console-selection sequence timed-out.
v A change in the system configuration affects the console (keyboard
installed/removed, mouse installed/removed, graphics adapter installed/removed or
moved to another PCI slot).
The
console-selection sequence allows you to select (from the appropriate input device)
any one of the available console devices. If no console is selected within approximately
60 seconds, serial port 1 (S1) is selected as the console and the selection sequence
times-out.
Attention: If an ASCII terminal is attached to serial port 1 (S1), and there is any
interaction with this terminal, then:
v After OK displays in the operator panel
AND
v Before the power-on sequence is initiated
the
firmware will use this terminal as the console, regardless of the previous console
selection.
Chapter 1. Reference Information 5
After a console has been selected, the console-selection sequence is only started at
boot time if there is a change in the system configuration (as described above), or the
contents of the system’s nonvolatile memory (NVRAM) are lost.
Note: Moving an ASCII terminal from one serial port to another (from S1 to S2) cannot
be detected by the firmware, so it does not constitute a configuration change.
You can also initiate a system console-selection sequence from the SMS menus.
Power-On Self-Test
After power is turned on and before the operating system is loaded, the system does a
power-on self-test (POST). This test performs checks to ensure that the hardware is
functioning correctly before the operating system is loaded. During the POST, a POST
screen displays, and POST indicators appear on the firmware console (if one is
connected). The next section describes the POST indicators and functions that can be
accessed during the POST.
POST Indicators
POST indicators indicate tests that are being performed as the system is preparing to
load the operating system. The POST indicators are words that display on the system
console. Each time that the system starts a different step in the POST, a POST
indicator word appears on the console. Each word is an indicator of the tests that are
being performed.
The POST screen displays the following words:
Memory Memory test
Keyboard Initialize the keyboard and mouse. The time period for pressing a key
to access the System Management Services, or to initiate a service
mode boot is now open. See “POST Keys” for more information.
Network Self-test on network adapters
SCSI Adapters are being initialized
Speaker Sounds an audible tone at the end of POST
POST Keys
The POST keys, if pressed after the keyboard POST indicator displays and before the
last POST indicator speaker displays, cause the system to start services or to initiate
service mode boots used for configuring the system and diagnosing problems. The keys
are described below:
Note: The program function keys (F1-F12) on a keyboard attached to the I/O drawer
are not used and will be ignored. After the keyboard POST indicator displays,
you must use the numeric number keys to enter input.
6 Service Guide
1 Key
The numeric 1 key, when pressed during POST, starts the System Management
Services (SMS) interface.
5 Key
The numeric 5 key, when pressed during POST, initiates a system boot in service mode
using the default service mode boot list.
This mode attempts to boot from the first device of each type found in the list. It does
not search for other bootable devices of that type if the first device is not bootable.
Instead, it continues to the next device type in the list. The firmware supports up to five
entries in the boot list.
The default boot sequence is:
1. Diskette
2. CD-ROM
3. Hard file
4. Tape drive (if installed)
5. Network
a. Token ring
b. Ethernet
6 Key
The numeric 6 key works like the numeric 5 key, except that firmware uses the
customized service mode bootlist that was set up using the AIX service aids.
8 Key
To enter the open firmware command line, press the numeric 8 key after the word
keyboard displays and before the last word speaker displays during startup. After you
press the 8 key, the remaining POST indicators display until initialization completes.
When initialization and POST are complete, the open firmware command line (an OK
prompt) displays.
The open firmware command line should only be used by service personnel to obtain
additional debug information.
To exit from the open firmware command prompt, type reset-all or power off the
system and reboot.
System Unit Locations
The system consists of a minimum of two drawers in one rack: the CEC drawer and the
primary I/O drawer. These two components are connected by cables that transmit data
and control signals. An additional I/O drawer can be added if further expansion of the
system is required. The following figure shows the units.

System Memory
Two slots are available for system memory riser cards. The system memory riser cards
are located for easy access in the CEC drawer. (These slots are shown in “System
Board Locations” on page 20.) Each memory riser card has 16 DIMM slots.
Four sizes of DIMMs are available: 128 MB, 256 MB, 512 MB and 1 GB. In addition,
certain 32 MB DIMMS from earlier RS/6000 systems can also be used.
One-Way Processor Memory Placement Rules
The rules for one-way processor memory are as follows:
v Minimum memory is 1 pair of DIMMs in slots 1 and 8 (see “One-Way Processor Card
Memory DIMM Locations” on page 22).
v Maximum memory is 4 DIMM pairs in slots 1 through 8 (see “One-Way Processor
Card Memory DIMM Locations” on page 22).
v Each memory riser slot must have a memory filler card installed.
v When you are installing a memory riser card:
– Memory DIMMs must be moved from the one-way processor card to the memory
riser card.
– The memory riser card must then have a minimum of four DIMMS (1 quad).
Riser Card Memory Placement Rules
The rules for riser card memory are as follows:
v Memory quads must contain DIMMs of equal memory size.
v Quad memory size may be mixed on a riser card.
v The minimum memory is four DIMMs. This memory must occupy quad A, which is
slots 1, 2, 15, and 16 (see “Memory Riser Card and Memory DIMM Locations” on
page 21).
v Populate the riser card starting with quad A and continuing with quads B, C, and D
(see “Memory Riser Card and Memory DIMM Locations” on page 21).
26 Service Guide
I/O Drawer Features
I/O drawers may have two redundant power supplies. One of these power supplies is
capable of providing the necessary voltages and currents independently of the other.
The left and right power supply output voltages are connected and monitored by the
power distribution board contained in the 5 EIA-unit I/O drawer. Both power supplies
provide +12 V dc to the fans in the drawer to ensure sufficient cooling if one of the
supplies fails. However, the short circuit prevention is on the I/O board to protect
against shorts in one output, thus causing the +12 V dc to fail completely.
The left and right power supplies are hot-pluggable and may be changed one-at-a-time
while the system is operational. Each power supply provides 5 V dc, 3.3 V dc, 12 V dc,
and 5 V dc standby power.
The 5 V dc standby power is provided by both power supplies; this can be done
because the power supplies contain overload protection against one supply shorting the
other. Standby power (5 V dc) is provided to the part of the primary I/O drawer planar
on which the SPCN and service processor logic reside.
I/O Drawer Addressing
I/O drawer addressing refers to the drawer number that is displayed in the operator
panel on secondary I/O drawers. This address is the drawer’s location in the RIO
(remote I/O) loop. The drawer number is displayed in the form U0.n, where n is the
drawer number. The primary I/O drawer number is 1 by default, but it is not displayed
on the operator panel. The first time that the system is booted after a service action or
configuration change that involves an I/O drawer or its backplane, the system may
detect a duplicate or incorrect I/O drawer number. This situation can result in duplicate
or incorrect drawer numbers being displayed when the system is booting up. The final
drawer number will be assigned and displayed, when the bootup is complete. The
drawer numbers are not reassigned unless a service action or configuration change
occurs.
When ac power has been disconnected from the system or from a drawer, then
reconnected, the I/O drawer address temporarily displays in the format *0n, where n is
the drawer number. After the system is powered on, and the boot sequence has been
initiated, the drawer numbers are restored to the U0.n format.

Message Hierarchy for Secondary I/O Drawer Operator Panel
The messages that are displayed in the operator panel on secondary I/O drawers are
arranged hierarchically, from highest priority to lowest priority. The message hierarchy is
as follows:
1. 8-character error code
This indicates a critical error; the drawer power will be shut down. Standby power is
still on, so the error message is still displayed in the operator panel. The I/O drawer
Attention LED will be on. The error code displays on the top line of the display
panel, left-justified. A FRU part number may also be displayed, right-justified, in the
second line of the display.
2. 8-character informational message
This is a noncritical message, so the drawer power will not be shut down. The
message should be investigated to see if service actions are indicated. A FRU part
number may also be displayed, right-justified, in the second line of the display.
When 8-character codes are displayed, they are in the form 10n1xxxx, where n is
the drawer number.
3. 8-character checkpoint
There is one 8-character checkpoint that will be displayed, 10n100AA, where n is the
drawer number. This checkpoint indicates that the system power control network
firmware is being updated, and the checkpoint will be displayed for approximately
15 seconds. This is the only checkpoint that displays on a secondary I/O drawer
operator panel.
4. Drawer number
This will be in the form U0.n, where n is the drawer number. This message will
normally be displayed unless a higher-level message is required.
When ac power has been disconnected from the system, then reconnected, the I/O
drawer addresses on the secondary drawers will temporarily display in the format
*0n, where n is the drawer number. After the system is powered on, and the boot
sequence has been initiated, the drawer numbers are restored to the U0.n format.

Chapter 1. Reference Information 31
Logical and Physical Locations
The system uses physical location codes in conjunction with AIX location codes to
provide mapping of the failing field replaceable units (FRUs). The location codes are
produced by the system unit’s firmware and the AIX operating system.
Physical Location Codes
Physical location codes provide a mapping of logical functions in a platform (or
expansion sites for logical functions, such as connectors or ports) to their specific
locations within the physical structure of the platform.
Location Code Format
The format for the location code is a string of alphanumeric characters separated by a
dash (-), slash (/), pound sign (#) or period (.) character. The base location is all of the
information preceding the slash (/) or pound sign (#). The base location identifies a
device that is connected to or plugged into the parent. Extended location information
follows the slash (/). Extended location information identifies a device that is part of the
parent, a connector, or a cable. Cable information follows the pound sign (#). Cable
information identifies a cable that is connector to parent. The following are examples:
v P1-C1 identifies a processor card C1 plugged into planar P1.
v P1-M1 identifies a memory card M1 plugged into planar P1.
v P1-K1 identifies a keyboard attached to K1 on planar P1.
v P1/S1 identifies serial port 1 controller on planar P1, the connector for serial port 1,
or the cable attached to serial port 1.
v P1-I2/E3 identifies an Ethernet controller 3 on the card in slot 2 (I2) on planar P1, the
connector for Ethernet controller 3, or the cable attached to Ethernet controller 3.
v P1-I2#E3 identifies the cable attached to Ethernet controller 3 on the card in slot 2
(I2) on planar P1.
The
period (.) identifies sublocations (DIMMs on a memory card, SCSI addresses,
cables). The following are examples:
v P1-M1.4 identifies DIMM 4 on memory card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 plugged into processor card 1 which is plugged into
planar P1.
v U0.1-P1/Z1–A3 identifies a SCSI device with SCSI ID 3 attached to SCSI bus 1 on
planar 1 in the primary I/O drawer.
v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3
attached to SCSI bus 1 from planar 2.
v P1-I2#E3.2 identifies the second in a series of cables attached to Ethernet controller
3 on the card in slot 2 (I2) on planar P1.
Depending
on the AIX and firmware levels, AIX diagnostics may include the extended
location information when identifying a planar or card. The extended location
information or cable information is always included when identifying a cable or
connector. Location codes with extended location information that are displayed without
a description identifying the devices always identify the cable attached to the port.
32 Service Guide
Multiple FRU Callout Instructions
If an eight-digit error code appears in the operator panel display or in Chapter 5, “Error
Code to FRU Index,” on page 163, a location code for a failing part may also be
specified. If the location code includes a blank space followed by a lowercase x
followed by a number, this is an error code with multiple FRU callouts. This error can
typically happen with memory DIMMs, memory riser cards, or processors and may
involve mixed types of parts. In this case, check the system’s configuration FRU part
numbers to determine the appropriate set of FRUs.
For example, if the location code U1.1-P1-M1.1 x2 was displayed, this indicates
memory pair A (two DIMMs) on the first memory riser card was suspected.
You can determine the FRU part numbers of the electronic assemblies in the system in
two ways:
v Using the service processor menus
From the general user menu, select Read VPD Image from Last System Boot,
then enter 90 to display detailed vital product data (VPD).
v Using the lscfg -vp | pg command on the AIX command line
Type the following command: lscfg -vp | pg to display the detailed VPD of all
assemblies. Notice that the FRU part number information for processors and memory
DIMMs may be at the bottom of the command output.
Chapter 1. Reference Information 33
AIX Location Codes
The basic formats of the AIX location codes are as follows:
v For non-SCSI devices/drives:
– AB-CD-EF-GH
v
For SCSI devices/drives:
– AB-CD-EF-G,H
For
planars, cards, and non-SCSI devices, the location code is defined as follows:
AB-CD-EF-GH
| | | |
| | | Device/FRU/Port ID
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
v The AB value identifies a bus type or PCI parent bus as assigned by the firmware.
v The CD value identifies adapter number, adapter’s devfunc number, or physical
location. The devfunc number is defined as the PCI device number times 8, plus the
function number.
v The EF value identifies a connector.
v The GH value identifies a port, address, device, or FRU.
Adapters
and cards are identified only with AB-CD.
The possible values for CD depend on the adapter/card. For pluggable PCI
adapters/cards, CD is the device’s devfunc number (PCI device number times 8, plus
the function number). The C and D are characters in the range of 0-9, and A-F (hex
numbers). The location codes therefore uniquely identify multiple adapters on individual
PCI cards.
EF is the connector ID, used to identify the adapter’s connector to which a resource is
attached.
GH is used to identify a port, device, or FRU. For example:
v For async devices, GH defines the port on the fanout box. The values are 00 to 15.
v For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.
v For all other devices, GH is equal to 00.
For
integrated adapter, EF-GH is the same as the definition for a pluggable adapter. For
example, the location code for a diskette drive is 01-D1-00-00. A second diskette drive
is 01-D1-00-01.
34 Service Guide
For SCSI devices, the location code is defined as follows:
AB-CD-EF-G,H
| | | | |
| | | | Logical Unit address of the SCSI Device
| | | Control Unit Address of the SCSI Device
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
Where:
v AB-CD-EF are the same as non-SCSI devices.
v G defines the control unit address of the device. Values of 0 to 15 are valid.
v H defines the logical unit address of the device. Values of 0 to 255 are valid.
A
bus location code is also generated as ’00-XXXXXXXX’, where XXXXXXXX is
equivalent to the node’s unit address.
Examples of physical location codes and AIX location codes are:
1. PCI adapter in primary I/O drawer, slot 1
v Location Code U0.1-P1-I1
v AIX Location Code 11-08
2.
PCI adapter in secondary I/O drawer, slot 1
v Location Code U0.2-P1-I1
v AIX Location Code 51-08

Cabling the CEC Drawer, Primary I/O Drawer, and Secondary I/O Drawer
The minimum system consists of two drawers. The CEC drawer contains the system
processors, memory and supporting hardware. The primary I/O drawer contains PCI
adapters, operator panel, disk drives, and media drives. The Model H80 and Models
6H0 and 6H1 must have one primary I/O drawer, which contains the service processor
for the system. The system supports up to two I/O drawers in various rack
configurations.
There are two steps to connecting the CEC drawer to the I/O drawers.
1. Connect the cables that only connect the CEC drawer and the primary I/O drawer,
such as the JTAG and the V/S COMM cable.
2. Connecting the cables that connect the CEC drawer and all the I/O drawers in
loops, such as the RIO cables and the SPCN cables.
All
power cables connect to the PDU. If a second PDU is specified along with
secondary drawer power supplies for all drawers,the secondary power supplies connect
to the secondary PDU.
Connecting JTAG and VS COM Cables
Use the following figure to connect the JTAG and V/S COMM cables.

Connecting RIO and SPCN Cables
The RIO and SPCN cables provide two functions in the system: remote data bus
connection and power control. The following basic rules must be followed when
connecting these two types of cables:
v The I/O drawers must be connected in a loop fashion for both the RIO cables and
the SPCN cables. The loop connection provides redundant paths so that if a failure
occurs in part of a cable, the system will continue to operate. If a failure occurs, a
warning message is displayed on the system console but the system continues to
operate.
v One loop is required for the SPCN cabling. This loop begins and ends at the primary
I/O drawer.
v Two loops are possible for the RIO cabling, depending on the number and desired
configuration of I/O drawers. These loops begin and end at the primary I/O drawer.
Chapter 1. Reference Information 49
RIO Cabling
The following rules apply to RIO cable connections:
v I/O drawers 0 and 1 are connected using the first RIO loop, which uses RIO ports 0
and 1 on the CEC drawer.
v The primary I/O drawer must be installed and connected to RIO port 0 of the CEC
drawer. The connection must be made from RI0 port 0 of the CEC drawer to RIO
port 0 of the primary I/O drawer. This connection is required to make the primary
drawer the first drawer in the loop, which allows the firmware to initialize the system.
The
following figures provide cabling examples for all valid cabling configurations.
Match your configuration to the correct figure and connect your RIO cables as shown.

Chapter 2. Diagnostics Overview
Model H80 and Models 6H0 and 6H1 systems use an integrated set of software
diagnostic procedures to facilitate isolation of failing components and system
maintenance. This book, along with the RS/6000 and Eserver pSeries Diagnostics
Information for Multiple Bus Systems, are the basis of the diagnostic procedures for
Model H80 and Models 6H0 and 6H1 systems. In particular, the following sections in
this book are important for the trained service representative to understand and use
when isolating a failure on the system:
v Chapter 4, “Checkpoints,” on page 137
v Chapter 5, “Error Code to FRU Index,” on page 163
v Chapter 6, “Loading the System Diagnostics In Service Mode,” on page 367
v Chapter 10, “Parts Information,” on page 469
The
manufacturer recommends that systems configured with 4 GB of memory or
greater have access to a 4 mm or 8 mm tape drive for submission of system dump
information if required. This function can be accomplished through locally attached or
network-attached devices, as appropriate.
Maintenance Analysis Procedures (MAPs)
Maintenance analysis procedures (MAPs) guide the trained service person through the
system. These MAPs are the entry point for all isolation and error-recovery procedures.
The MAPs are consistent with existing procedures and methods. The system uses a set
of integrated procedures, mentioned earlier, to which the MAPS are the primary entry
point.
The MAPS are as follows:
v Entry MAP
v Quick Entry MAP
v Problem Determination MAP
v Power MAP
v Minimum Configuration MAP
The
Entry Map is the starting point for problem determination. The purpose of this MAP
is to quickly point to the appropriate MAP or service reference information either in this
book, or in the common book set, which includes the RS/6000 and Eserver pSeries
Diagnostics Information for Multiple Bus Systems and the PCI Adapter Placement
Reference.
The Quick Entry MAP is a subset of the Entry MAP and helps to save time for some
types of problems.
The Problem Determination MAP provides a structured analysis method to get an error
code if one is not provided by the customer, or if diagnostics cannot be loaded.
69
The Power MAP deals with isolation of components to diagnose a power problem. The
nature of power problems can be related to powering on and down the system, or
power failures that can occur after power is turned on.
The Minimum Configuration MAP is used to locate defective components not found by
normal diagnostics or error-isolation methods. This MAP provides a systematic method
of isolation to the failing item or items.
Checkpoints
These servers use various types of checkpoints, error codes, and SRNs, which are
referred to throughout this book (primarily in Chapter 4, “Checkpoints,” on page 137,
Chapter 5, “Error Code to FRU Index,” on page 163, Chapter 6, “Loading the System
Diagnostics In Service Mode,” on page 367, and Chapter 10, “Parts Information,” on
page 469). These codes may appear in the service processor boot progress log, the
AIX error log, and the operator panel display. Understanding the definition and
relationships of these codes is important to the service personnel who are installing or
maintaining these servers.
Codes that can appear on the operator panel or in error logs are as follows:
Checkpoints
Checkpoints display in the operator panel from the time ac power (dc power in
a dc-powered system) is connected to the system until the AIX login prompt is
displayed after a successful operating system boot. These checkpoints have
the following forms:
8xxx 8xxx checkpoints display from the time ac power (dc power in a
dc-powered system) is connected to the system until the OK prompt is
displayed by the service processor on the operator panel display.
(Several 9xxx checkpoints are displayed just before the OK prompt
displays.)
9xxx 9xxx checkpoints are displayed by the service processor after the
power-on sequence is initiated. A system processor takes over control
when 91FF displays on the operator panel.
Exxx Exxx checkpoints indicate that a system processor is in control and is
initializing the system resources. Control is being passed to AIX when
E105 (normal mode boot) or E15B (service mode boot) displays on the
operator panel.
Note: Location code information may also display on the operator
panel during this time.
0xxx
0xxx codes are AIX checkpoints and configuration codes. Location
codes may also be shown on the operator panel display during this
time.
2xxx 2xxx codes are AIX checkpoints and configuration codes. Location
codes may also be shown on the operator panel display during this
time.
70 Service Guide
Note: Certain checkpoints may remain in the display for long periods of time.
A spinning cursor is visible in the upper-right corner of the display
during these periods to indicate that system activity is continuing.
Error
Codes
If a fault is detected, an 8-digit error code is displayed in the operator panel
display. A location may be displayed at the same time on the second line of
the display.
Checkpoints can become error codes if the system fails to advance past the
point at which the code was presented.
For a list of checkpoints, see Chapter 4, “Checkpoints,” on page 137. Each
entry provides a description of the event and the recommended action if the
system fails to advance.
SRNs Service request numbers, in the form xxx-xxx or xxx-xxxx, may also be
displayed on the operator panel display and be noted in the AIX error log.
SRNs are listed in the RS/6000 and Eserver pSeries Diagnostics Information
for Multiple Bus Systems, order number SA38-0509.
FRU Isolation
For a list of error codes and recommended actions for each code, see Chapter 5, “Error
Code to FRU Index,” on page 163. These actions can refer to Chapter 10, “Parts
Information,” on page 469, Chapter 3, “Maintenance Analysis Procedures (MAPs),” on
page 75, or provide informational message and directions. If a replacement part is
indicated, direct reference is made to the part name. The respective AIX and physical
location codes are listed for each occurrence as required. For a list of locations codes,
see “AIX and Physical Location Code Reference Tables” on page 36.
To look up part numbers and view component diagrams, see Chapter 10, “Parts
Information,” on page 469. The beginning of the chapter provides a parts index with the
predominant field replaceable units (FRUs) listed by name. The remainder of the
chapter provides illustrations of the various assemblies and components which make up
these servers.
Electronic Service Agent for the Eserver pSeries and RS/6000
Service support for your system can be enhanced through the use of the application
program, Electronic Service Agent. This application provides a number of advantages
for the systems customer, including automatic error reporting and analysis without
customer intervention. The Electronic Service Agent kit includes the Electronic Service
Agent for Eserver pSeries and RS/6000 CD, order number LCD4–1060, which
contains documentation to help you set up and use Electronic Service Agent.
Chapter 2. Diagnostics Overview 71
Using the Service Processor and Electronic Service Agent Features
The service processor and Electronic Service Agent features protect users against
unnecessary system downtime by advising support personnel (both internal and
external) of any unexpected changes in the system environment. In combination, the
two features provide a flexible solution to automated system maintenance.
Service Processor
The service processor runs on its own power boundary and continually monitors
hardware attributes, the AIX operating system, and the environmental conditions within
the system. Any system failure which prevents the system from returning to an
operational state (a fully functional AIX operating system) is reported by the service
processor. The service processor is controlled by firmware and does not require the AIX
operating system to be operational to perform its tasks. If any system failures are
detected, the service processor has the ability to take predetermined corrective actions.
The methods of corrective actions are:
v Surveillance
v Call home
v AIX operating system monitoring
Surveillance
is a function in which the service processor monitors the system through
heartbeat communication with the system firmware. The heartbeat is a periodic signal
that the firmware can monitor. During system startup, the firmware surveillance monitor
is automatically enabled to check for heartbeats from the firmware. If a heartbeat is not
detected within a default period, the service processor cycles the system power and
attempts to restart until the system either restarts successfully, or a predetermined retry
threshold is reached. In the event the service processor is unsuccessful in bringing the
system online (or in the event that the user asked to be alerted to any service
processor-assisted restarts), the system can call home to report the error.
The call home function can be initialized to call either a service center telephone
number, a customer administration center, or a digital pager telephone number. The
service processor can be configured to stop at the first successful call to any of the
numbers listed, or can be configured to call every number provided. If connected to the
service center, the service processor transmits the relevant system information (the
system’s serial number and model type) and service request number (SRN). If
connected to a digital pager service, the service processor inputs a customer voice
telephone number defined by the customer. An established sequence of digits or the
telephone number to a phone near the failed system could be used to signal a system
administrator to a potential system failure.
During normal operations, the service processor can also be configured to monitor the
AIX operating system. If AIX does not respond to the service processor heartbeat, the
service processor assumes the operating system is hung. The service processor can
automatically initiate a restart and, if enabled, initiate the call home function to alert the
appropriate people to the system hang. Enabling operating system surveillance also
enables AIX detect any service processor failures and report those failures to the
Electronic Service Agent application.
72 Service Guide
Unlike the Electronic Service Agent, the service processor cannot be configured in a
client/server environment where one system can be used to manage all dial-out
functions for a set of systems.
Prior to installing the Electronic Service Agent feature, ensure that you have the latest
level of system firmware. You also need a properly configured modem. For more
information on configuring a modem, see “Modem Configuration Menu” on page 391.
Electronic Service Agent
The Electronic Service Agent is a software extension to the AIX operating system that
monitors the system while the AIX operating system is running. The Electronic Service
Agent monitors and analyzes all recoverable system failures, and, if needed, can
automatically place a service call to a service center (without user intervention).
The service center receives the machine type/serial number, host name, SRN, and a
problem description. The service center analyzes the problem report and, if warranted,
dispatches a service person to the customer site. The service center also determines if
any hardware components need to be ordered prior to the service person’s arrival.
The Electronic Service Agent code also gives the user the option to establish a single
system as the problem reporting server. A single system, accessible over the user
network, can be used as the central server for all the other systems on the local area
network (LAN) that are running the Electronic Service Agent application. If the
Electronic Service Agent application on a remote client decides a service request needs
to be placed, the client forwards the information to the Electronic Service Agent server
that dials the service center telephone number from its locally attached modem. In this
scenario, the user only needs to maintain a single analog line for providing call-out
capabilities for a large set of servers.
When used in a scalable parallel (SP) environment, a client/server type implementation
is configured. The Electronic Service Agent client code runs on each of the SP nodes.
The server component runs on the control workstation. In the event of any system
failures, the relevant information is transmitted to the control workstation through the
integrated Ethernet. After it has been alerted to the system failure, the control
workstation initiates actions to prepare and send the service request.
A modem is required for enabling automated problem reporting to the service center.
Configuration files for several types of modems are included as part of the Electronic
Service Agent package. Refer to “Modem Configuration Menu” on page 391 for more
information on configuring your modem.
Chapter 2. Diagnostics Overview 73
74 Service Guide
Chapter 3. Maintenance Analysis Procedures (MAPs)
This chapter contains maintenance analysis procedures (MAPs) for the system.
Entry MAP
Use the following table to determine your starting point. When possible, run online
diagnostics in service mode. Online diagnostics perform additional functions, compared
to standalone diagnostics. This ensures that the error state of the system is captured in
NVRAM for your use in fixing the problem. The AIX error log and SMIT are only
available when diagnostics are run from the hard drive.
Notes:
1. Licensed programs frequently rely on system information stored on the VPD module
on the operator panel assembly. If the MAPs indicate that the operator panel
assembly should be replaced, swap the VPD module from the old operator panel to
the new one. If recovery is not possible, notify the system owner that new keys for
licensed programs may be required.
2. If a network adapter is replaced, the network administrator must be notified so that
the client IP addresses used by the server can be changed. In addition, the
operating system configuration of the network controller may need to be changed in
order to enable system startup. Also check to ensure that any client or server that
addresses this system is updated.
3. If you are servicing an SP system, go to the Start-of-Call MAP 100 in the SP
Systems Service Guide.
4. If you are servicing a clustered Eserver system, go to the start of call MAP 100 in
the Clustered Eserver Installation and Service Guide.
