vi Hardware Maintenance Manual: xSeries 250

General checkout

The server diagnostic prog rams are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server: The system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives, and parallel port. You can also use them to test some external devices. See “Diagnostic programs and error messages” on page 25.

Also, if you cannot determine whether a problem is caused by the hardware or by the softw a re, you ca n run the diagnostic programs t o confirm tha t the hard ware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

A failed system might be par t of a shared DASD cluster (two or more systems sharing the same external storage device(s)) . Prior to running diagnostics, verify that th e failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

• The customer identifies the system as part of a cluster.

• One or more external storage units are attached to the system and at least one of the attached storage units is additionally attached to another system or unidentifiable source.

• One or more sy stems are locate d near the failing system.

If the failing system is suspected to be part of a shared DASD cluster, all diagnostic tests can be run except diagnostic tests which test the storage unit (DASD residing in the storage unit) or the storage adapter attached to the storage unit.

Notes:

1. For systems that are part of a shared DASD cluster, run one test at a time in looped mode. Do not run all tests in looped mode, as this could enable the DASD diagnostic tests.

2. If multiple error code s are displaye d, dia gno se the first error code disp layed.

3. If the computer hangs with a POST error, go to the “Symptom-to-FRU index” on page 143.

4. If the computer hangs and no error is displayed, go to “Undetermined problems” on page 170.

5. Power supply problems, see “Symptom-to-FRU index” on page 143.

6. Safety information, see “Safety information” on page 180.

7. Fo r in termitte nt pro b le ms , check the erro r l og; see “POS T error messag es ” on page 14.

1. IS THE SYSTEM PART OF A CLUSTER?

YES. Schedule maintenance with the customer. Shut down all systems related to the cluster. Run storage test.

NO. Go to step 2.

2. THE SYSTEM IS NOT PART OF A CLUSTER.

• Power-off the computer and all external devices .

• Check all cables and power cords.

• Set all display controls to the middle position.

• Power-on all external devices.

• Power-on the computer.

• Record any POST error messages displayed on the screen. If an error is displayed, look up the first error in the “POST error codes” on page 155.

• Check the information LED panel System Error LED; if on, see “Diagnostic panel LEDs” on page 146.

• Check the System Error Log. If an error was recorded by the system, see “Symptom- to- F RU index” on page 143.

• Start the Diagnostic Programs. See “Diagn ostic programs and error messages” on page 25.

• Check f or the following responses: a. One beep. b. Readable instructions or the Main Menu.

3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?

NO. Find the failure symp tom in “Symptom-to-FRU index” on pa g e 14 3.

YES. Run the Diagnosti c Programs. If necessary, refer to “Diagnostic programs and

error me ssages” on page 25.

If you receive an err or, go to “Symptom-to-FRU index” on page 143.

If the diagnostics completed successfully and you still suspect a problem, see “Undetermined problems” on page 170.

The unique design of the server takes advantage of advancements in symmetric multiprocessing (SMP), data storage, and memory protection. The server combines:

• Impressive performance using an innovative approach to SMP The server supports up to four Pentium III Xeon microprocessors. The server

comes with one microprocessor installed; you can install additional microprocessor s to enhance performance and provide SMP capability.

• Integrated disk-array subsystem (optional) Although many operating systems provide software fault tolerance through

mirroring, IBM provides hardware fault tolerance through the redundant array of independent disks (RAID) controller. The IBM ServeRAID™ controller is a standard feature. It provides three channels and supports RAID levels 0, 1, 1E, 5, and 5E.

• Large data-storage and hot-s wap capa bilit ies All models of the server suppo r t up to 10 slim-high dis k driv es. The hot-swap

feature enables you to remove and replace hard disk drives without turning off the server.

• Hot-plug PCI adapter capabilities The server ha s f our hot-plug slots for PCI adapters. With operating system

support, you can replace failing hot-plug PCI adapters without turning off the server. If the hot-add feature is supported by the operating system and the PCI adapter, you can also add PCI adapters in these slots without turning off the server.

• Redundant cooling and power capabilities The redundant cooling and hot-swap capabilities of the fans in the server enable

continued operation if one of the fans fails, because you can replace a failing fan without turning off the server.

The server comes standard with three 250-watt power supplies, which support redundancy for a typical configuration. You can install one additional power supply.

• Large sy stem memory The memory bus in the server supports up to 16 GB of system memory. The

memory controller provides error correcting code (ECC) support for up to 16 industry-sta ndard, 3. 3 V, 168-pin, 8-byte, register ed, dual inlin e memory modules (DIMMs). The memory controller also provides Chipkill™ memory protection. Chipkill memory protect ion is a technolo gy that protects the syste m from component fa ilure on a DIMM.

• System-management capabilities The serve r comes with a Advanced System Management Process or. This

processor enables you to manage the functions of the server locally and remotely . The Advanced System Management Processor also provi des system monitoring, event recording, and dial-out alert capability.

General information 5

Note: The Advanced System Management Processor is sometimes referred to as

the service processor.

Refer to “Advanced System Management ports” on page 104 for more information.

• Integrated network environment support The server comes with an Ethernet controller . This Ethernet controller has an

interface for connecting to 10-Mbps or 100-Mbps networks. The server automatically sel e cts between 10BASE-T and 100BASE-TX. The controller provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

• Redundant network-interface card The addition of an optional, red undant network interface card (NIC) provides a

failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associ ated with thi s primary connection is automatically switched to the redundant NIC. This switching occurs without data loss and without user intervention.

• IBM ServerGuide CDs The ServerGuide CDs included with the server provide pro gra ms to help you set

up the server and install the network operating system (NOS). The ServerGuide program detects the hardware options that are installed, and provides the correct configuration program and device drivers. In addition, the ServerGuide CDs include a variety of application programs for the server.

Reliability, availability, and serviceability

Three of the most importan t featu res in server des ign a re reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on the server; that the server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.

Diagnostic tools overview

The following tools are available to help you identify and resolve hardware-related problems:

• POST beep cod es , error me ss ages , and error l ogs

The power-on self-test (POST) generates beep codes and messages to indicate successfu l test completion or the detection of a proble m. See “POST” on page 14 for more information.

• Diagnostic programs and error messages

• Light path diagnostics

Your server has light-emitting diodes (LEDs) to help you identify problems with server components. These LEDs are part of the light-path diagnostics that are built into the server. By following the path of lights, you can quickly identify the type of system error that occurred. See “Light path diagnostics” on page 28 for more information.

• Error symptoms

POST

These charts list problem symptoms, along with suggested steps to correct the problems. See the “Diagnosing error s” on page 35 for more information .

When you turn on the server, it performs a series of tests to check the operation of server components an d some of the options installed in th e se rver. This se ries of tests is called the power-on self-test or POST.

If POST finishes without detec ting any pr oblems, a sin gle beep sounds, the f irst sc reen of the operating system or application progr am appears, and the System POST Complete (OK) light is illuminated on the operator information panel.

If POST detects a problem, more than one beep sounds and an error message appears on the screen. See “POST beep codes” and “POST error messages” for more information.

Notes:

1. If you have a powe r-on password or admini strator password set, you must type the password and press Enter, when prompted, before POST will continue.

2. A single problem might cause several error messages. When this occurs, work to correct the cause of the fir st e rror message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the te s t .

POST beep codes

POST generates beep codes to indicate successful completion or the detection of a problem.

• One beep indicates the successful completion of POST.

• More than one beep indicates that POST detected a problem. For more information, see “Beep symptoms” on page 143.

POST error messages

POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration. For a list of POST errors, see “POST error codes” on page 155.

Event/error logs

The POST error log contains the three most recent error codes and messages that the system generated during POST. The System Event/Error Log contains all error messages issued during POST and all sy stem status mess ages from the Advanc e d System Managem e nt Processor.

To view the contents of the error logs, start the Configuration/Setup Utility program; then, se l e c t Ev ent/Error Logs from the main menu.

Small computer system interface messages

If you receive a SCSI error message, see “SCSI error codes” on page 165. Note: If the server does not have a har d di sk drive, ignor e any message that indicates

that the BIOS is not installed.

14 Hardware Maintenance Manual: xSeries 250

You will get these messages only when running the SCSISelect Utility.

Solvin g ServeR AI D problems

This section desc ribes the Serv eRAID text and numeric messages that might appear during startup. This section also includes some basic information about rebuilding a defunct drive .

In addition to the information provided in this section, you might want to use the ServeRAID IPSSEND program to help isolate ServeRAID problems.

ServeRAID controller messages

This section lists the ServeRAID messages that might appear during system startup. The ServeRAID cont roller s provide a Device Ev en t Log that collect s statist ics on the

number and types o f events that occur on a selected physical drive. After correct ing a problem with the array, clear the log so that you can identify any subsequent errors quickly. For information about clearing the event log, see "eraseevent" on page 137.

All physical drives contain unique identifiers, such as the drive serial number and manufacturer. During configuration, the ServeRAID controller stores this information.

ServeRAID startup mess ages

During power-on self-test (POST), the ServeRAID controller compares the stored configuration informa tion to the configu ration that is actually present. If a discrepancy exists, one or more status messages appear after POST completes, but before the operating system loads.

Notes:

1. When the ServeRAID controller requires your input, a list of function keys will appear below the message.

2. Where the Action information tells you to start the IBM ServeRAID configuration program, insert the IBM ServeRAID Support CD into the CD-ROM drive; then, restart the server. The Action column also provides general information about the message.

3. Where SID or ch appears in these messages, sid is the SCSI ID for the device, and ch is the channel to which the device is attached.

4. Where m or n appears in these messages, a number will appear in the actual message.

Following are messages associated with the ServeRAID subsystem in alphabetical order.

A new drive was installed.

Explanation: When the ServeRAID controll er detect s a new drive that is not part of the

current confi guration, the following message appears: x new ready drives found where x is the number of ready drives found.

Action: This is an information message. No action is required.

F5 – Change the configu r atio n and set the dri ves to def unc t. Press this ke y to acce pt th e new state that the ServeRAID controller will assign to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty. You can also press F5 when you must remove a drive. RAID level-1 and RAID level-5 logical drives are present, and performance in a degraded mode is acceptable. The ServeRAID controller will assign the drive a state of defunct, but the server can complete startup. However, the array will remain in critical mode and the potential for data loss will exist until you replace and rebuild the defunct drive. To prevent the loss of data, replace and rebuild the defunct drive in a timely manner.

Note: A physical drive in the defunct st at e does not necessarily mean that you need to

replace the drive. Before you replace the drive, ensure t hat:

1. All cables are connected properly to the backplane and to the physical drive. Also, ensure that all cables inside the server are connected properly.

2. The hot-swap drive trays are seated properly in the drive bay.

3. Try rebuilding the drive if you have not already done so. See “Rebuilding a defunct drive” on page 23 for more information.

New controller install ed in a configured server or drives are imported.

Explanation: W hen the ServeRAID controller detect s t hat the identifiers of the drives do not

match the controller configuration information, the following message appears: x online drive(s) found with mismatch configuration Examples of possible messages: Configurat i on mismatch Channel 1 SC SI ID 0 with Host ID Configurat i on mismatch Channel 2 SC SI ID 0 with Host ID

Action: Press one of the following keys: F2 – Detailed description. Press this key f or a detailed descri ption of the pro blem, such as the

example messages above. F4 – Retry. Press this key after correcting the problem. For exa mple, press F4 after yo u move the physical drive to its pr eviously assigned location, or after you install the ori ginal physical drives back in the server . F5 – Change the configuration and set the drive to defunct. Press this key to accept the new state that the ServeRAID controller will assign to the drive. For example, the ServeRAID controller will assign the drive a state of defunct or empty. Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before you r eplace th e drive, ensure that:

1. All cables are connected prope rly to the backplane or processor or I/O board, and to the physical drive. Also, ensure that all cables inside the server are connected pr operly.

2. The hot-swap drive trays are seated properly in the drive bay.

3. If you have not already attempted to rebuild the drive, try rebuilding it. See “Rebuilding a defunct drive” on page 23 for more information.

After you perform these steps, if the physical drive does not function properly, replace the drive. F7 – Import configuration information from drive. Press this key to restart the server. Press this key to import the configuration information from the drive and to update the configuration information for the ServeRAID controller. This choice is useful when you replace the ServeRAID co nt roller in an existing ServeRAID subsystem. Y ou also might press F7 if you replace a whole set of drives with drives that were conf igured in another server with a ServeRAID controller. When you install drives in a server that has no logical drives defined, the F7 choi ce wil l not appe ar. The ServeRAID controller does no t contain any logic al drives in its factory configuration. Therefore, F7 will not appear. In this case, do the following:

1. Restart the server and press Ctrl+I to enter the Mini-Configuration program (see “Using the ServeRAID Mini-Configuration program” on page 130).

2. Select Advanced Functions.

3. Select Copy the Configura tion f rom Dri ves to t he Contr oller and follow the instructions on the screen.

WARNING: n logical drives are critical; n logical drives are offline.

Explanation: One or more physical drives have failed.

Action: Replace the defunct drives as soon as possible to prevent data loss. Your server has an error due to a Blocked Logical Drive.

Explanation: One or more logical drives are blocked. A blocked logical drive cannot be

accessed.

Action: Press F4 to unblock the logical drive, or press F5 to continue without un blo cki ng .

ServeRAID ISPR, BCS, and ECS POST error codes

After the ServeRAID POST completes, register information appears on the screen in hexadecimal format, as follows:

Hardware: ISPR=aaaa BCS=bb ECS=cc

ISPR displays the four-digit Interrupt Status Report Register code, BCS displays the Basic Configuration Status Register code, and ECS displays the Extended Configuration Status Register code.

For example:

Controller 1 Slot 5, Status:Not responding properly - Error Code=0B0 Controller 2 Slot 4, Logical Drive=0, Other=0, Firmware=2.88.10, Status=Ok Controller 3 Slot 3, Logical Drive=0, Other=0, Firmware=3.60.13, Status=Ok Controller 4 Slot 2, Logical Drive=1, Other=1, Firmware=1.00.09, Status=Ok

If no errors occur: ISPR (aaaa) = EF10 BCS (bb) = 0F or 09 ECS (cc) = 00 If an err or occurs , refer to: “ServeRAID POST (ISPR) error codes” on page 161 for th e

ISPR error codes and “Basic and Exten ded Configuration Status Regist e r Codes” on page 20 for the BCS and ECS error codes.
