This chapter contains Maintenance Analysis Procedures (MAPs) for the RS/6000 7046 Model B50.

Entry MAP

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 nonvolatile random access memory (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.

D 2. Online Diagnostics are only available when the AIX operating system is used. If D you have another operating system, run the Standalone Diagnostics from the D CD-ROM or the network.

3. Licensed programs frequently rely on either network configuration, vital product data (VPD) stored on the operator control panel assembly, or system board information to authorize program use. If the MAPs indicate that the network adapter, operator panel, system board, or network adapter should be replaced, notify the system owner that new keys for licensed programs may be required.

4. If a network adapter or the system 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 may need to be changed in order to enable system startup. In addition, check to ensure that any client or server that addresses this system is updated.

5. After completing the recommended actions in this chapter, go to "MAP 0410: Repair Checkout" in Diagnostics Information for Multiple Bus Systems.

Chapter 3. Error Code to FRU Index

The Error Code to FRU Index lists error symptoms and possible causes. The most likely cause is listed first. Use this index to help you decide which FRUs to replace when you are servicing the system.

If the codes in the following tables indicate a device which is present more than once in the server, a location code is needed to specify which device generated the error. Go to “Step 1020-3” on page 2-8 to display the System Management Services error log and obtain a location code. Location code descriptions can be found under Chapter 4, “Location Codes” on page 4-1.

Once you have the location code, see Chapter 8, “Parts Information” on page 8-1 for the part number.

Notes:

1. 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 Chapter 4, “Location Codes” on page 4-1.

2. Licensed programs frequently rely on network configuration and system information stored on the VPD on the operator panel. If the MAPs indicate that the operator panel should be replaced, swap the VPD from the old operator panel to the new one. If the old VPD module has to 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.

If you replace FRUs and the problem is still unresolved, go to “Step 1540-1” on page 2-18, unless otherwise indicated in the tables. If you replace FRUs and the problem has been resolved, go to "MAP 0410: Repair Checkout" in the Diagnostics Information for Multiple Bus Systems, unless otherwise indicated in the tables.

21A00xxx SCSI Device Errors SCSI device error notes:

Repair Action/Possible Failing FRU

Values normally found in nonvolatile storage that point to the location of an Operating System were not found. This can happen for either of two reasons:

 Your installed Operating System does not support

storing the values.

 Some event occurred that caused the system to

lose nonvolatile storage information (drainage or replacement of the battery).

If you are running AIX, this information can be reconstructed by running the bootlist command specifying the device that the Operating System is installed on. Please refer to your AIX documentation for the exact syntax and usage of the bootlist command.

To boot the Operating System so that these values can be reconstructed, power down the system and power it back up again. This should cause the system to look for the Operating System in the devices contained in the custom boot list or in the default boot list, depending on the condition of the system. If this is not successful, use the System Management Services Menus to modify the Boot Sequence (also known as boot list) to include devices that are known to contain a copy of the Operating System. For example, select a hard disk known to have a copy of the Operating System as the first and only device in the boot sequence (boot list) and attempt to boot again.

Modify the Boot Sequence (also known as boot list) to include devices that are known to contain a copy of the Operating System. This can be accomplished by powering down the system, powering it back up again, and using the System Management Services Menus. For example, select a hard disk known to have a copy of the Operating System as the first and only device in the boot sequence (boot list) and attempt to boot again.

1. Before replacing any system components: a. Ensure that the controller and each device on

the SCSI bus is assigned a unique SCSI ID. b. Ensure SCSI bus is properly terminated. c. Ensure SCSI signal and power cables are

securely connected and not damaged.

2. The location code information is required to identify the ID of SCSI device failures, as well as to indicate the location of the controller to which the device is attached.

Repair Action/Possible Failing FRU

1. Errors reported against NVRAM can be caused by low battery voltage and (more rarely) power outages that occur during normal system usage. With the exception of the 25A80000 error, these errors are really just warnings that the NVRAM data content had to be re-established and do not require any FRU replacement unless the error is persistent. When one of these errors occurs, any system customization (for example boot device list) information has been lost. The system may need to be reconfigured.

2. If the error is persistent, replace the battery.

3. If the error is persistent after battery replacement, or the error code is 25A80000, replace the system board (see note 3 on page 2-1).

Refer to 25A80xxx.

Turn off, then turn on the server and retry the operation before replacing any system components.

Repair Action/Possible Failing FRU

Refer to 25A80xxx.

Execution of a command line within the nvram configuration variable “nvramrc” (script) resulted in a “throw” being executed. This script can be modified by the system firmware SMS utilities, the operating system, PCI adapter rom code or utility, or an operator (via the open firmware script editing command nvedit). It may not be possible to resolve the problem without a detailed analysis of the nvram script, the current system configuration, and device tree contents.

1. The problem can be caused by a SCSI adapter,whose SCSI bus ID has been changed from the default setting, no longer appearing in the system. This can be caused either by removing a SCSI adapter, or a problem with a SCSI adapter.

a. Select the SCSI ID utility from the SMS

menu(s).

1) Verify the list of SCSI controllers/adapters. If the list is not correct, suspect a problem with the adapter(s) installed but not listed.

2) Select the option to save the configuration information.

3) Restart the system.

b. If the problem persists, boot the operating

system and verify the SCSI bus IDs of any installed/available SCSI controllers (change as necessary), and restart the system.

2. Contact your service support representative for further assistance.

This is a firmware debug environment error. There is no user action or FRU replacement for this error.

Bus SRN to FRU Reference Table

This table is used to locate defective FRUs within the system board PCI and ISA buses, and indicates which devices should be tested for each SRN. For this procedure, if possible, diagnostics are run on the riser card bus devices with all adapters removed from the failing bus. If a failure is detected on this system with all adapters removed from the failing bus, the riser card is the isolated FRU. If a failure is not detected, the adapters are added back one at a time, to their original slot location, and the configuration is tested until a failure is detected. The failure is then isolated to the failing FRU.

If a failure has not been detected and all the FRUs have been tested, call your technical service support person for assistance.

Boot Problems or Concerns

Depending on the boot device, a checkpoint may be displayed on the operator panel for an extended period of time while the boot image is retrieved from the device. This is particularly true for Tape and Network boot attempts. If booting from CD-ROM or Tape, watch for activity on the drive's LED indicator. A blinking LED indicates that the loading of either the boot image or additional information required by the operating system being booted is still in progress. If the checkpoint is displayed for an extended period of time and the drive LED is not indicating any activity, there may be a problem loading the boot image from the device.

Note: For network boot attempts, if the system is not connected to an active

network or if the target server is inaccessible (this can also result from incorrect IP parameters being supplied), the system will still attempt to boot. Because time-out durations are necessarily long to accommodate retries, the system may appear to be hung.

This section assumes that a CD-ROM drive is installed and a Diagnostics CD-ROM is available.

1. Restart the system and get to the Firmware SMS Main Menu. Select Multiboot.

 Check if the intended boot device is correctly specified in the boot sequence.  Verify that a boot image resides on the media of the specified boot devices.

– Unload any removable (ie. Diskette, CD-ROM, or Tape) media that can

not be verified.

– If the intended boot device is not correctly identified in the boot

sequence, add it to the boot sequence using the SMS menus. If the intended boot device cannot be added to the boot sequence go to step

3. – If attempting to boot from the network go to step 2. – If attempting to boot from a disk drive or CD-ROM go to step 3.

2. If attempting to boot from the network:

 Verify that IP parameters are correct.  Attempt to "Ping" the target server using the SMS Ping utility. If the ping is

successful, have the network administrator verify the server configuration for this client.

 Turn power Off, then On and retry the boot operation.  Check the network cabling to adapter.

3. Try to boot and run standalone diagnostics against the system, particularly against the intended boot device.

Chapter 3. Error Code to FRU Index 3-27

 If the intended boot device is not listed in the NEW RESOURCE list, go to

"MAP 0290: Missing Resource Problem Resolution" in Diagnostics

Information for Multiple Bus Systems.

 If an SRN, not an 8-digit error code, is reported, go to Diagnostics

Information for Multiple Bus Systems.

 If the diagnostics are successful, it may be necessary to perform an

operating system-specific recovery process, or reinstall the operating system.

 If unable to load standalone diagnostics:

a. Verify that the SCSI bus is properly terminated. b. Check the SCSI cabling. c. It is possible that another attached SCSI device is causing the problem.

– Disconnect the signal and power cables from any other SCSI devices

attached to the SCSI adapter that the CD-ROM drive is attached to. – Try to boot the standalone diagnostics again. – If unable to load standalone diagnostics, go to step 4. – If standalone diagnostics load, one of the disconnected devices is

causing the problem, reconnect the devices one at a time. Retry the

boot operation until the problem recurs and replace the device that

caused the problem. If the problem appears to be one of the SCSI

devices, be aware it could be either the SCSI device or the SCSI

adapter. Go to "MAP 0410: Repair Checkout" in Diagnostics

Information for Multiple Bus Systems.

4. It is possible that another installed adapter is causing the problem.  Remove all installed adapters except the one the CD-ROM drive is attached

to and the one used for the console.

 Try to boot the standalone diagnostics again.  If unable to load standalone diagnostics, go to step 5.  If standalone diagnostics load, reinstall adapters (and attached devices as

applicable) one at a time. Retry the boot operation until the problem recurs. Then replace the adapter or device that caused the problem (the system board can also cause the device or adapter to fail). Go to "MAP 0410: Repair Checkout" in Diagnostics Information for Multiple Bus Systems.

5. Either the CD-ROM drive, SCSI adapter, the graphics adapter, or the system

board is most likely defective. A tty terminal attached to serial port 1 also can be used to determine if the graphics adapter is causing the problem. This is done by removing the graphics adapter, attaching a tty terminal to serial port 1, and retrying standalone diagnostics. If the standalone diagnostics load, replace the graphics adapter.

 If the CD-ROM drive is attached to a SCSI adapter card rather than the

integrated SCSI adapter on the system board:

– Replace the SCSI adapter. – Replace the riser card.

3-28 7046 Model B50 Service Guide

 Replace system board (see note 3 on page 2-1).  If you replaced the indicated FRUs and the problem is still not corrected, or

the above descriptions did not address your particular situation, go to “MAP 1540: Minimum Configuration” on page 2-17.

 Go to "MAP 0410: Repair Checkout" in Diagnostics Information for Multiple

3-30 7046 Model B50 Service Guide

Chapter 4. Location Codes

The RS/6000 7046 Model B50 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 format for the location code is a string of alphanumeric characters separated by a dash (-), slash (/), pound sign (#), or period (.).

 The base location is all of the information before the slash (/) or pound sign (#).

It identifies a device that is connected or plugged into the parent.

 Extended location information follows the slash (/). It identifies a device that is

part of the parent, a connector, or a cable.

 Cable information follows the pound sign (#). It identifies a cable that is

connected to the parent.

The following are examples:

P1-C1 Identifies a CPU card C1 plugged into planar P1. P1-M1 Identifies a memory card M1 plugged into planar P1. P1-K1 Identifies a keyboard attached to connector K1 on planar P1. P1/S1 Identifies serial port 1 controller on planar P1, the connector for serial port

1, or the cable attached to the connector for serial port 1.

P1-I2/E3 Identifies Ethernet controller 3 on the card plugged into slot 2 (I2) on

planar P1, the connector for Ethernet controller 3, or the cable attached to Ethernet controller 3.

P1-I2#E3 Identifies the cable attached to Ethernet controller 3 plugged into slot 2

(I2) on planar P1.

Sub-locations, such as memory modules on a base memory card or a specific SCSI address, are identified by a period (.). The following are examples:

P1-M1.4 Identifies DIMM 4 on memory card 1 on planar 1.

Chapter 4. Location Codes 4-1

1-C1.1 Identifies CPU 1 on CPU card 1 on planar 1. P2/Z1-A3.1 Identifies a SCSI device with a SCSI address of LUN 1 at SCSI ID 3

attached to SCSI bus 1 from planar 2.

P1-I2#E3.2 Identifies the second cable in a series of cables attached to Ethernet

controller 3 in slot 2 (I2) on planar 1.

Depending on the AIX and firmware levels, AIX Diagnostics may include extended location information when identifing a planar or card. The extended location information is always included when identifing a cable or connector. Location codes with extended location information that display without a description identifing the devices, always identify the cable attached to the port.

AIX Location Codes

The basic formats of the AIX location codes are:

 For non-SCSI devices/drives:

AB-CD-EF-GH

 For SCSI devices/drives:

AB-CD-EF-G,H

Non-SCSI Devices/Drives

The location code for for planars, cards, and non-SCSI devices is defined as:

AB-CD-EF-GH

Chapter 4. Location Codes 4-3

 The AB value identifies a bus type or PCI parent bus as assigned by the

firmware.

 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.

 The EF value identifies a connector.  The GH value identifies a port, address, device, or FRU.

Adapters and cards are identified 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 lowercase are omitted) and are equal to the parent bus's ibm, aix-loc Open Firmware Property.

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). Location codes therefore uniquely identify multiple adapters on individual PCI cards.

 For pluggable ISA adapters, CD is equal to the order the ISA cards

defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.

 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 is 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:

4-4 7046 Model B50 Service Guide

 For async devices, GH defines the port on the fanout box. The values are 00 to

15.

 For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.  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.

SCSI devices/drives

The location code for SCSI devices and drives is defined as:

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.
