Electrical Safety

Observe the following safety instructions any time you are connecting or disconnecting devices attached to the workstation.

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

Before installing or removing signal cables, ensure that the power cables for the system unit and all attached devices are unplugged.

When adding or removing any additional devices to or from the system, ensure that the power cables for those devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables to prevent a possible shock from touching two surfaces with different electrical potentials.

During an electrical storm, do not connect cables for display stations, printers, telephones, or station protectors for communications lines.

CAUTION: This product is equipped with a four-wire power cable and plug for the user’s safety. Use this power cable in conjunction with a properly grounded electrical outlet to avoid electrical shock.

DANGER

To prevent electrical shock hazard, disconnect all power cables from the electrical outlet before relocating the system.

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.

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 (-), 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.

Chapter 1. Reference Information 9

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 controller on planar P2 which drives connector

Z1.

v P2-Z1-... points to the actual SCSI bus and devices attached to Z1.

The . (period) identifies sub locations (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

10 Service Guide

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: 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 ISAAdapter Configuration Service Aid.

v For 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, 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.

Chapter 1. Reference Information 11

For integrated adapters, 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.

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 that 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

v Second memory card in planar P1:

P1-M2

v Memory DIMM 12 on second memory card plugged into planar P1:

P1-M2.12

12 Service Guide

The manufacturer recommends that systems configured with 4 GB of memory or greater have access toa4mmor8mmtape 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 Power MAP deals with isolation of components to diagnose a power problem. The nature of power problems can be related to powering up and down the system, 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.

Model 270 servers use various types of checkpoints, error codes, and SRNs, which are referred to throughout this book (primarily in “Chapter 4. Checkpoints” on page 71, “Chapter 5. Error Code to FRU Index” on page 93, “Chapter 6. Loading the System Diagnostics” on page 147, and “Chapter 10. Parts Information” on page 277). 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 Model 270 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 is connected to the system until the AIX login prompt is displayed after a successful operating system boot. These checkpoints have the following forms:

E000 - E075

These checkpoints display from the time ac power is connected to the system until the OK prompt displays on the operator panel display. During this time, the service processor performs self-test and NVRAM initialization.

E0A0 - E0E1

When power up is initiated, the service processor starts built-in self-test (BIST) on the central electronics complex (CEC). VPD data are read.

E0E2 - E2xx

This range indicates that the system processor is in control and is initializing system resources.

E3xx These codes indicate that the system processor is running memory

tests.

E1xx The system firmware attempts to boot from devices in the boot list.

Control is passed to AIX when E105 (normal mode boot) or E15B (service mode boot) displays on the operator panel display.

0xxx 0xxx codes are AIX checkpoints and configuration codes. Location

codes may also be shown on the operator panel display during this time.

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 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

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.

communication with the system firmware. The heartbeat is a periodic signal

24 Service Guide

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.

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 “Appendix E. Modem Configurations” on page 299.

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 “Appendix E. Modem Configurations” on page 299 for more information on configuring your modem.

Chapter 2. Diagnostics Overview 25

26 Service Guide

Chapter 3. Maintenance Analysis Procedures (MAPs)

This chapter contains maintenance analysis procedures (MAPs).

Notes:

1. 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 (non-volatile random access memory) for your use in fixing the problem. The AIX error log and SMIT are only available when diagnostics are run from the hard drive.

2. If more than eight digits are displayed in the operator panel, use only the first eight digits to find the error in the tables. The digits that display beyond the first eight digits are location codes that can assist you in diagnosing the problem. See “Location Codes” on page 9.

3. Licensed programs frequently rely on network configuration and system information stored on the VPD (vital product data) module on the operator panel control assembly. If the MAPs indicate that the operator panel control assembly should be replaced, swap the VPD module from the old operator panel to the new one. If the existing VPD module must be replaced, call technical support for recovery instructions. If recovery is not possible, notify the system owner that new keys for licensed programs may be required.

4. If a network adapter or the I/O board 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 might 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.

Chapter 4. Checkpoints

Checkpoints let users and service personnel know what the system is doing, with some detail, as it initializes. These checkpoints are not intended to be error indicators, but in some cases the system could hang at one of the checkpoints without displaying an 8-character error code. It is for these hang conditions, only, that any action should be taken with respect to checkpoints. The most appropriate action is included with each checkpoint.

Before taking actions listed with a checkpoint, it is a good idea to look for more appropriate symptoms in the service processor error log. See “Chapter 7. Using the Service Processor” on page 149.

Service Processor Checkpoints

Service processor checkpoints are in the range E001 to E0FF. The message OK indicates successful service processor testing and initialization. Firmware checkpoints are listed in “Firmware Checkpoints” on page 75.

Note: Go to “MAP 1540: Minimum Configuration” on page 50 for any of the following

conditions:

v A four-digit code in the range of E001 through EFFF displays on the operator panel

but is not listed in the checkpoint table.

v A four-digit code displays in the checkpoint table, but does not contain a repair action

or FRU listing.

Firmware Checkpoints

Firmware uses progress codes (checkpoints) in the range of E1xx to EFFF. These checkpoints occur during system startup and can be useful in diagnosing certain problems. Service processor checkpoints are listed in “Service Processor Checkpoints”

on page 71.

If you replace FRUs and the problem is still not corrected, go to “MAP 1540: Minimum Configuration” on page 50 unless otherwise indicated in the tables.

If you replace FRUs or perform an action, and the problem is corrected, go to "MAP 410: Repair Checkout" in the
