Note: 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. 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 control assembly. If the MAPs indicate that the Operator Panel Control Assembly 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.

3. 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 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.

General Memory Information

Be sure to unplug the power cable before removing or installing the memory card(s) or memory modules to avoid damage to them.

Memory cards can be installed in either slot (or both) on the system board, there is no requirement that one be installed before the other.

It is perfectly acceptable for there to be two partially populated memory cards in the system, the first memory card does not have to be fully populated before memory on the second memory card is useable.

Memory modules, on the other hand, must be installed in matched (size and speed) pairs. Refer to “Memory Modules” on page 7-14 for labeling of the memory card and instructions on module removal and installation (do not, however, replace the covers as directed while troubleshooting this problem). A single memory module pair may be installed in module slots J1 and J2 (not slots J1 and J3). A second memory module pair could be installed in module slots J5 and J6 (slots J3 and J4 do not have to be populated first). Along these same lines, there is no requirement that memory module slots J1 and J2 be populated before another slot pair.

Notes:

1. Be sure to unplug the power cable before removing or installing processor card(s), memory card(s), system board or I/O board to avoid damage to them.

2. This MAP assumes that a CD-ROM drive is installed and connected to the integrated SCSI adapter, and a Diagnostics CD-ROM is available.

3. If a power-on password or privileged-access password is installed, you are prompted to enter the password before the diagnostic CD-ROM can load.

4. The term "POST indicators" refer to the icons (graphic display) or device mnemonics (ASCII terminal) that appear during the power-on self-test (POST).

5. The Service Processor may have recorded one or more symptoms in its error log. It is a good idea to examine that error log before proceeding (see Service Processor System Information Menu).

6. The Service Processor may have been set by the user to monitor server operations and to attempt recoveries. You may wish to disable these actions while you diagnose and service the system. If you disable them, you should make notes of their current settings for restoration before you leave. Following are the settings of your interest.

Surveillance From the Service Processor Setup Menu, go to

the Surveillance Setup Menu and disable surveillance.

Unattended Start From the Service Processor System Power

Control Menu disable unattended start mode.

Reboot Policy From the System Power Control Menu go to the

Reboot/Restart Policy Setup Menu and set:

1. Number of reboot attempts to 0 (zero)

2. Use OS-Defined restart policy to No

3. Enable supplemental restart policy to No.

Call Out From the Call-In/Call-Out Setup Menu, go to the

Serial Port Selection Menu and disable call-out on both serial ports.

Purpose of this MAP

This MAP is used to locate defective FRUs not found by normal diagnostics. For this procedure, diagnostics are run on a minimally-configured system. If a failure is detected on the minimally-configured system, the remaining FRUs are exchanged one at a time until the failing FRU is identified. If a failure is not detected, FRUs are added back until the failure occurs. The failure is then isolated to the failing FRU.

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 servicing the system.

If the codes in the following tables indicate a device which is present more than once in the system unit, a location code is needed to specify which device generated the error. Go to “Step 1020-4” on page 2-14 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:

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 not corrected, go to “MAP 1540: Minimum Configuration” on page 2-31. unless otherwise indicated in the tables.

in non-volatile storage.

20EE000B The system was not able to find an

operating system on the device list that was attempted.

Values normally found in non-volatile storage that point to the location of an Operating System were not found. This can happen for two reasons, either your installed Operating System doesn't support storing the values or some event occurred that caused the system to lose non-volatile 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.

In order to boot the Operating System so that the above mentioned values can be reconstructed,power the system down 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, 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 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.
