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.

Models S80 and S85 Overview
The models S80 and S85 systems are exclusively multi-processor, multi-bus systems
packaged in two different rack types. The processors and memory are packaged in the
system rack and the DASD and I/O devices are in I/O drawers. The basic system
consists of one system rack and one I/O drawer in a separate rack. The system is
expandable to one system rack and four I/O drawers in up to four I/O racks. Connection
between the system rack and subsequent I/O drawers is made through a number of
cables, which include SPCN (system power control network), RIO (remote input output),
JTAG, and operator panel cables.
The system rack is powered independently from the I/O drawer. The system rack
supports a minimum of one processor card to a maximum of four. Each processor card
has six processors, each having its own L2 cache. The system memory is controlled
through a multi-port controller complex and supports up to 16 memory slots. The total
memory available to the system user is dependent on the memory feature card installed
and the number of memory cards. All system memory resides in the system rack.
Additional major functional units in the system rack include the operator panel and
control circuitry, the SPCN controller, interrupt, and system bus control logic. Power is
brought into the system rack through an ac power cord (200 - 240 V ac), distributed to
six bulk supplies and then fed through regulators for both system resources and logic
and memory.
The I/O rack holds the I/O drawer, which provides for up to 14 PCI adapters per drawer.
Four distinct peripheral component interface (PCI) buses are present in each I/O
drawer. The primary I/O drawer (drawer 0) has PCI slots 6, 7, 8, and 13 reserved for
the system media, Service Processor and DASD bays resident in the I/O drawer. These
slots are available in subsequent I/O drawers 1 through 3 for any supported PCI
adapter to use. The PCI bus speed is 33Mhz with both 32- and 64- bit adapters
supported on a slot basis. Slots 1, 5, 9, 10 and 14 support either 32- or 64- bit PCI
adapters. The remaining slots are 32 bit only. “Models S80 and S85 Data Flow” on
page 2 illustrates the system data flow.
The I/O drawer provides space for up to three media devices (tape, CD-ROM, and
diskette drive) and two DASD bays, each holding up to six disk drives.

Powering the System On and Off
The system can be powered on after the following cables are connected:
v All RIO cables
v All SPCN cables
v JTAG cable
v Inter-rack operator panel cable
v All PCI cables to supported drawers
After the required cables are installed and the power cables are connected, the power
button on the system operator panel can be pushed one time to initialize the system (if
the button is pushed two times, the system powers off). Progress indicators, also
referred to as checkpoints, are visible on the operator panel display and the green LED
to the right of the power button illuminates, indicating the system power is on.
The remote I/O drawers are powered up through the system power control network
(SPCN) controls and interfaces in both the system rack and I/O drawers. When power
is applied, a light-emitting diode (LED) on the I/O drawer indicator panel goes from
blinking (green) to on continuously, which indicates that power levels are satisfactory in
the drawers.
If the system is operating under AIX, enter the shutdown -F command to power off the
system. If you cannot use this method, you can power off the system by pressing the
operator panel power button two times.
Attention: Using the operator panel power pushbutton to power off the system may
cause unpredictable results in the data files, and the next IPL will take longer to
complete.
For complete details on how to power the system on and off, go to “Powering Off and
Powering On the System” on page 492 and “System Power-On Methods” on page 470.
Console Strategy
The firmware invokes 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 occurred in the system configuration affecting the console (keyboard
installed/removed, mouse installed/removed, graphics adapter installed/removed or
moved to another PCI slot).
The console-selection sequence allows the selection (from the appropriate input device)
of one of the available console devices. If no console is selected within approximately
60 seconds, serial port 1 (com1) is selected as the console, and the selection sequence
times out.
Chapter 1. Reference Information 3
After a console has been selected, the console-selection sequence is only invoked 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) is lost.
Note: Moving an ASCII terminal from one serial port to another (from com1 to com2)
cannot be detected by the firmware, so it does not constitute a configuration
change.
A system console-selection sequence can also be initiated from the System
Management Servies (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 is displayed, and POST indicators appear on the system 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 appear as words on the system
console. Each time the system starts a different step in the POST, a POST indicator
word displays on the console. Each word indicates the tests that are being performed.
The POST screen displays the following words:
Memory
Memory test
Keyboard
Initialize the keyboard and mouse. The window for pressing a key to access
the System Management Services, or to boot from a default boot list 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 displays, cause the system to invoke services or boot modes used
for configuring the system and diagnosing problems. The keys are described below:
4 Service Guide
Numerical 1 Key
The numerical 1 key, when pressed during POST, invokes the System Management
Services (SMS) interface.
Numerical 5 Key
The numerical 5 key, when pressed during POST, invokes a service mode boot using
the default 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 numerical 5 key is used to boot the system in service mode to run stand-alone
diagnostics.
The default boot order is:
1. Diskette
2. CD ROM
3. Hard file
4. Tape drive
5. Network
a. Token ring
b. Ethernet
Numerical 6 Key
The numerical 6 key works like the numerical 5 key, except firmware looks for a boot
record according to the custom bootlist that was set up by System Management
Services.
The numerical 6 key is used to boot the system in service mode to run online
diagnostics.
Numerical 8 Key
To enter the open firmware command line, press the numerical 8 key after the keyboard
icon displays and before the last icon (the speaker icon) displays during startup. After
pressing the numerical 8 key, the remaining POST indicators display until initialization
completes.
When initialization and power-on self-test (POST) are complete, the open firmware
command line (an OK prompt) displays.
The open firmware command line is used to set up adapters that are not configurable
with the System Management Services. Your adapter documentation directs you to use
this option if it is needed.
To exit from the open firmware command, type reset-all or power down the system
and reboot.

Models S80 and S85 Locations
Models S80 and S85 systems consist of a minimum of two racks — the system rack
and the input/output rack (I/O rack). These two components are connected by cables
that transmit data and control signals. Additional I/O racks can be added if further
expansion of the system is required. The following illustration shows the two racks.

System and I/O Rack Configurations
Model S80 and S85 systems can be set up in various configurations regarding the
placement of the primary I/O drawer. Typically, the primary I/O drawer is installed in an
I/O rack with other drawers attached to the same system rack. If two systems are
installed side-by-side, then the two systems can share one I/O rack by installing both
primary I/O drawers in the same rack. This can be done to save space and also if the
systems are used for high-availability (HA) applications. The following illustrations show
some basic configurations.

System Memory
All system memory for the models S80 and S85 system is provided on several sizes of
memory cards, which are plugged into reserved slots.
There are 16 slots available for system memory, and they are located for easy access
from the front or rear of the system rack. These slots are shown in:
“System Rack Locations Front” on page 17
shows the relative positions to the system rack
“System Rack Locations Rear” on page 18
shows the relative positions to the system rack
“Memory Locations and Ordering Rules”
a top view including the processor and clock cards
The memory cards are M01 through M03 and M08 through M10 on the front of the
system, and M11 through M15 and M20 through M24 on the rear of the system.
Memory cards are available in several sizes: 256MB, 512MB, 1024MB, 2048MB, and
4096MB.
Memory Locations and Ordering Rules
The following illustration is a top-level view of the system memory. This view shows a
full configuration of memory cards installed into the system backplane.
R1 memory cards are used in models S80 and S85 systems. All memory cards are
installed in four-card functional units called quads. The quads must be composed of
four cards of the same type. The complete set of four cards must be properly installed
in the proper card slots for the newly installed memory to work correctly. See the
following illustration for the locations of the card slots that are in each quad.
Certain technical applications must have the memory configured for optimal
performance. The memory system of the models S80 and S85 is accessed through two
separate ports. Optimization is achieved by equalizing as much as possible the amount
of memory on each of the ports. Quads A and D are on one port. Quads B and C are
on the other port.
To upgrade the system for optimal performance, sort all of the memory features by
quad size, from largest to smallest. Install the largest memory feature in quad A, insert
the next largest memory feature in quad B. Continue inserting memory quads in the
available quads alphabetically, with the smaller features following the larger.

Cabling the System Rack and I/O Rack
The minimum system consists of two racks. The system rack contains the system
processors, memory, and supporting hardware. The I/O rack contains I/O drawer(s) with
PCI adapters, disk drives, and media drives. The models S80 and S85 must have a
minimum of one I/O drawer. This primary I/O drawer contains the service processor for
the system. Additional I/O drawers can be added to the system. These secondary I/O
drawers are connected to the system rack but do not contain a service processor. The
models S80 and S85 supports up to a total of four I/O drawers in different I/O rack
configurations.
Use the following steps to connect the system rack to the I/O drawers in their I/O racks:
1. Connect the JTAG cable and the operator panel cable. These two cables are
connected only between the system rack and the primary I/O drawer. See
“Connecting JTAG and Operator Panel Cables” on page 32 for illustrations showing
these cables.
2. Connect the RIO cables, and the SPCN cables. These cables connect between the
system rack and all the I/O drawers in loops. See “Connecting RIO and SPCN
Cables” on page 32 for illustrations showing these cables.
Chapter 1. Reference Information 31
Connecting JTAG and Operator Panel Cables
Use the following illustration to connect the JTAG and operator panel (OP) cables.
Connecting RIO and SPCN Cables
The RIO and SPCN cables provide two functions in the models S80 and S85 system:
remote data bus connection and power control. The following 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 displays 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 system
rack.
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 system rack.

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 system rack.
v I/O drawers 2 and 3 are connected using the second RIO loop, which uses RIO ports
2 and 3 on the system rack.
v The primary I/O drawer must be installed and connected to RIO port 0 of the system
rack. The connection must be made from RI0 port 0 of the system rack 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.
v If the loop connection between RIO 2 and RIO 3 is broken, the system is not able to
differentiate between I/O drawer 2 and I/O drawer 3. The system still conillustrations
RIO 0 and RIO 1 ports, but does not conillustration RIO 2 or RIO 3 ports.
The following illustrations provide cabling examples for all valid cabling configurations.

Models S80 and S85 Power Overview
The models S80 and S85 power is provided to each rack type by independent power
supplies and distribution cabling. Both the system racks require 200 to 240 V ac power
connections. The system rack and the I/O rack have independent power distribution
systems.
System Rack Power
The power enters the processor system rack as 200-240 V ac. The line cord enters the
ac box, which contains two components; one is the ac filter and distribution assembly,
and the other supplies standby power to some system components. Standby power is
supplied to the operator panel interface and the System Power Control Network
(SPCN).
The filtered 200-240 V ac is then sent to the four (five on fully configured systems)
system bulk power supplies. The supplies are coupled together and provide an N+1
level of redundancy for protection. N+1 refers to the fact that because the supplies are
coupled to a common distribution bus, if one of the supplies fails, the system will not
fail. The bulk supplies provide a positive 29-volt output, which is fed to the system
regulator located above the bulk supplies and to the system blowers.
The system blowers maintain the system temperature within the strict guidelines
required in an N+1 arrangement. Each blower can be powered off individually so that a
blower can be removed and replaced without turning off the system power. The blowers
only require +29 V dc.
The system regulators provide 2.5 V dc and 3.3 V dc to the system.
I/O Rack Power
The I/O rack power-distribution network is shown in the illustration found under “I/O
Drawer Cabling” on page 41.
Power enters the I/O rack as 200-240 V ac through a power cable assembly and
terminates on a power distribution bus (PDB). The PDB has six individual ac outlets,
each capable of eight amps at 200-240 V ac, which are overload-protected and
resettable. Each I/O drawer is supplied from one ac outlet of the PDB through a special
“Y” cable. The “Y” cable draws power from a single PDB outlet and provides a standard
ac plug to each of the two power supplies used in each I/O drawer. Two I/O drawers
are allowed in each rack, but other type drawers can be installed in addition to the two
I/O drawers.
Ten EIA-unit I/O drawers 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 together and
monitored by the power distribution board contained in the 10 EIA-unit I/O drawer.
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,
and5Vdcstandby.
38 Service Guide
The5Vdcstandby power is provided by both power supplies and connected together
on the I/O planar directly because the power supplies contain overload protection
against one supply shorting the other. Standby power of +5 V dc is provided to a
portion of the I/O planar, which is part of the system SPCN logic. This consists of
several components, including a logic chip, ROM, SRAM, and transceivers. The service
processor is not on standby power. 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 planar to protect against inadvertent shorts in one
line, causing the +12 V dc to fail completely.

from overheating, retain the cables with unlocking wire ties as shown.
SCSI IDs and Bay Locations
The following illustrations show the SCSI IDs for media and disk drives. The SCSI IDs
for media devices installed in bank A at the factory are set using jumpers on the drives
when they are installed. The SCSI IDs are set as shown in the following illustration.
The SCSI IDs for the hot-swap disk drives installed in banks C and D are set when the
drive is installed. There are no SCSI jumpers to set; the SCSI ID is controlled by the
position in which the drive is installed.

Chapter 1. Reference Information 43
Location Codes
This system unit uses physical location codes in conjunction with AIX location codes to
provide mapping of the failing field replaceable units. The location codes are produced
by the system unit’s firmware and AIX.
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 location code is an alphanumeric string of variable length, consisting of a series of
location identifiers, separated by a dash (-), or slash (/), or a pound sign (#) character.
The series is hierarchical; that is, each location identifier in the string is a physical or
logical child of the one preceding it.
v The - (dash) separator character represents a normal structural relationship where
the child is a separate physical package and it plugs into (or is connected to) the
parent. For example, P1-C1 is a processor card (C1) plugged into a planar (P1), or
P1-M1 is a memory card (M1) plugged into a planar (P1).
v The / (slash) separator character separates the base location code of a function from
any extended location information. A group of logical devices can have the same
base location code because they are all on the same physical package, but may
require extended location information to describe the connectors they support. For
example, P2/S1 describes the location of the serial port 1 controller and its connector
(S1), which is located on planar P2 (its base location code), but the / indicates that
further devices can be connected to it at the external S1 serial connector. The
keyboard controller and its connector likewise have location code P2/K1, which
means they have the same base location code (P2) as serial port 1, but a different
external connector. In contrast, the location code P2-K1 actually points to the device
connected to connector K1; that is, the keyboard. The location code P2/Z1 indicates
an integrated SCSI controller which drives connector Z1, while location codes of
P2-Z1-... point to the actual SCSI bus and devices.
v The # (pound sign) separator character indicates a cable connection between a
connector and parent.
The following are examples:
v P1-C1 identifies processor card C1 plugged into planar P1.
v P1-M1 identifies memory card M1 plugged into planar P1.
v P2/S1 identifies serial port 1 controller on I/O board P2 or the connector for serial
port 1.
v P1-K1 identifies a keyboard attached to connector K1 on planar P1.
v P2/Z1 identifies an integrated SCSI port controller on planar P2 which drives
connector Z1.
v P2-Z1-... points to the actual SCSI bus and devices attached to Z1.
44 Service Guide
The . (period) identifies sublocations (DIMMs on a memory card or SCSI addresses).
The following are examples:
v P1-M1.4 identifies memory DIMM 4 on memory card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.
v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3
attached to SCSI bus 1, which is integrated on planar P2.
v P2.1 identifies a riser card plugged into planar P2.
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
Non-SCSI Devices/Drives
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, the 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 AB are:
00 Processor bus
01 ISA bus
02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA buses
xy For PCI adapters where x is equal to or greater than 1. The x and y are characters in the
range of 0-9, A-H, J-N, P-Z (O, I, and lower case are omitted) and are equal to the parent
bus’s ’ibm, aix-location’ open firmware property.
The possible values for CD depend on the adapter/card:
Chapter 1. Reference Information 45
v 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). Location codes therefore uniquely identify multiple
adapters on individual PCI cards.
v For pluggable ISA adapters, CD is equal to the order of the ISA cards
defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
v For an integrated ISA adapters, CD is equal to a unique code identifying the ISA
adapter. In most cases, this code is equal to the adapter’s physical location code. In
cases where a physical location code is not available, CD will be FF.
EF is the connector ID. It is 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 re 00 a 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 an 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.
SCSI Devices/Drives
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 AB-CD-EF are the same as non-SCSI devices.
G defines the control unit address of the device. Values of 0 to 15 are valid.
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 displayed by AIX are as follows:
v First processor card plugged into planar 1:
P1-C1
46 Service Guide
v Second memory card in planar P1:
P1-M2
v Memory DIMM 12 on second memory card plugged into planar P1:
P1-M2.12
Examples of AIX location codes displayed are as follows:
v Integrated PCI adapter:
10-80 Ethernet
10-60 Integrated SCSI Port 1 (internal)
10-88 Integrated SCSI Port 2 (external)
v Pluggable PCI adapters:
20-58 to 20-5F Any PCI card in slot 1
20-60 to 20-67 Any PCI card in slot 2
10-68 to 10-6F Any PCI card in slot 3
10-70 to 10-77 Any PCI card in slot 4
10-78 to 10-7F Any PCI card in slot 5
v Integrated ISA adapters:
01-D1 Diskette adapter
01-R1 Parallel port adapter
01-S1 Serial port 1 adapter
01-S2 Serial port 2 adapter
01-S3 Serial port 3 adapter
01-K1 Keyboard adapter
v Device attached to SCSI controller:
10-60-00-4,0 Device attached to integrated SCSI Port 1

Service Inspection Guide
Perform a service inspection on the system when:
v The system is inspected for a maintenance agreement.
v Service is requested and service has not recently been performed.
v An alterations and attachments review is performed.
v Changes have been made to the equipment that may affect the safe operation of the
equipment.
v External devices with their own power cables have those cables attached.
If the inspection indicates an unacceptable safety condition, the condition must be
corrected before anyone can service the machine.
Note: The correction of any unsafe condition is the responsibility of the owner of the
system.
Perform the following checks:
1. Check the covers for sharp edges and for damage or alterations that expose the
internal parts of the system unit.
2. Check the covers for proper fit to the system unit. They should be in place and
secure.
3. Ensure that the rack stabilizer is installed and securely attached to the rack.
4. Perform the appropriate power-off procedures.
5. Open the covers.
6. Check for alterations or attachments. If there are any, check for obvious safety
hazards such as broken wires, sharp edges, or broken insulation.

72 Service Guide
Chapter 2. Introduction to Diagnostics
models S80 and S85 systems use an integrated set of software diagnostic procedures
to facilitate system maintenance. This book, and the Diagnostics Information for Multiple
Bus Systems, are the basis of the diagnostic procedures for models S80 and S85
servers. In particular, chapters 3, 4, 5, and 10 in this book are important for the trained
service representative to understand and use when isolating a failure on the system.
The manufacturer recommends that systems configured with 4GB of memory or greater
have access to a 4mm or 8mm 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) are used to guide the trained service person
through the complex multi-rack models S80 and S85 server. These MAPs are the entry
point for all isolation and error recovery procedures. models S80 and S85 servers use a
set of integrated procedures, 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 proper MAP or service reference information either in this book,
or in the common book set, which includes the Diagnostic Information for Multiple Bus
Systems and PCI Adapter Placement Reference.
The Quick Entry MAP is a subset of the Entry MAP and helps to save time for certain
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.
The Power MAP deals with isolation of components and cables to diagnose a power
problem. Power problems can be related to powering up and down the system
(including the I/O racks), or power failures that 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.

Error Codes
models S80 and S85 servers use multiple sets of error codes which are referred to
throughout this book (primarily in Chapters 4, 5 and 6). These codes are a blend of
traditional error codes and codes generated by newly integrated software used in
models S80 and S85 servers. Understanding the definition and relationships of these
codes is important to the service personnel who are installing or maintaining models
S80 and S85 servers.
Codes that can display on the operator panel or in error logs are as follows:
Checkpoints Checkpoints display on the operator panel during the initial program
load (IPL) of the system. Checkpoints indicate the progress of the
IPL.
Error Codes Error codes display on the operator panel if the system firmware
detects an error during IPL or during normal operation.
SRN Service request number (SRN) is usually a 6-digit number
representing a specific failure of a specific item. SRNs are displayed
on the system operator panel.
SRC System reference codes (SRC) are a sequence of codes that are
used to identify status and describe a failure. Failures can result from
hardware, software, or firmware. SRCs display on the system
operator panel. SRCs primarily deal with items pertinent to the system
rack and its associated hardware, software, and firmware.
Displaying and Using SRCs
SRCs automatically display on the system operator panel with operator panel “Function
11.” The four leftmost characters displayed describe the reference code identifier. The
four rightmost characters are the unit reference code. An SRC can consist of up to 36
bytes of information. You can view other words of the SRC by using the increment or
decrement functions on the operator panel.
Functions 11 and 13 through 19 are valid SRC data words. Word 19 provides the CCIN
number which identifies the specific failing memory or processor card in the system
rack. With this information, the service representative can identify the failing FRU and
order the correct part. The SRC types can be identified by the first digit after the 11-3 in
Function 11. The valid reference code identifiers for models S80 and S85 systems are
listed below.
0000 Hardware-reported error. A system problem resulted from a hardware problem.
1XXX Hardware-reported error. A system problem resulted from a hardware problem.
A1XX Attention or action required. The system is waiting for a user action.
B006 Machine check or internal problem detected by firmware. A firmware program
detected either a software or a hardware error.
B1XX Machine check or internal problem detected by firmware. A firmware program
detected either a software or a hardware error.
74 Service Guide
B4xx Machine check or internal problem detected by firmware. A firmware program
detected either a software or a hardware error.
C1XX IPL status. Status SRCs indicate the progression of the IPL.
C3XX IPL status. Status SRCs indicate the progression of the IPL.
D1XX General system status. Status SRCs indicate the status of system functions
when the console is not available.
IPL Checkpoints and Error Codes
models S80 and S85 servers provide checkpoints and error codes to display during
system initial program load (IPL). These checkpoints and error codes are unique to
particular instances and to hardware, software, and firmware components of the
system. The sets of checkpoints and error codes are listed below:
v Three-digit SRN of the form 101-xxx
v Eight-digit checkpoint in SRC format of the form C1XX-xxxx
v Eight-digit checkpoint in SRC format of the form C3XX-xxxx
v Four-digit checkpoints of the form E0XX
v Four-digit checkpoints of the form E1XX
v Four-digit checkpoints of the form E4XX
v Four-digit checkpoints of the form E5XX
Checkpoints can become error codes if the system fails to advance past the point at
which the code is presented. SRNs are listed in Diagnostic Information for Multiple Bus
Systems. “Chapter 4. Checkpoints” on page 135 in this book contains a list of the
checkpoints. Each entry provides a description of the event and the recommended
action if the system fails to advance.
FRU Isolation
For a list of error codes and recommended actions for each code, see “Chapter 5. Error
Code to FRU Index” on page 157. These actions can refer to “Chapter 10. Models S80
and S85 Parts” on page 535, “Chapter 3. Maintenance Analysis Procedures (MAPs)” on
page 79, or provide informational message and directions. If a replacement part is
indicated, the part name is included. The respective AIX and physical location codes
are listed per each occurrence as required. Locations codes are listed under “AIX and
Physical Location Code Reference Tables” on page 48.
To determine part numbers and view component diagrams, see “Chapter 10. Models
S80 and S85 Parts” on page 535. 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 that make
up models S80 and S85 systems. System rack components are listed first, then I/O
rack, and then accessories.
Chapter 2. Introduction to Diagnostics 75
Electronic Service Agent
Service support for the models S80 and S85 can be enhanced through the use of the
application program, Electronic Service Agent. This application provides a number of
advantages for the models S80 and S85 customer including automatic error reporting
and analysis without customer intervention. The Electronic Service Agent kit is shipped
with the models S80 and S85 server and includes the following:
v Electronic Service Agent program on diskette
v Appropriate modem for remote communication
v Applicable cables
v Electronic Service Agent User’s Guide, for Electronic Service Agent.
See the Electronic Service Agent User’s Guide, for more details on Electronic Service
Agent.
Using the Service Processor and Electronic Service Agent
The service processor and electronic service agent features protect users against
unnecessary system downtime by keeping support personnel (both internal and
external) aware 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 that 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 can take predetermined corrective actions. The
methods of corrective actions are as follows:
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
76 Service Guide
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
affords AIX the means to detect any service processor failures and report those failures
to the electronic service agent application.
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
functionally for a set of systems.
Prior to installing the service processor feature, ensure that you have the latest levels of
service processor microcode and system firmware. You also need a properly configured
modem. For more information on configuring a modem, see “Modem Configuration
Menu” on page 461.
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 who
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
Chapter 2. Introduction to Diagnostics 77
integrated Ethernet. After it is 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 IBM 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 461
for more information on configuring your modem.
