vi Hardware Maintenance Manual: xSeries 250

General checkout

The server diagnostic programs 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 software, you can run the diagnostic programs to confirm that the hardware 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 part of a shared DASD cluster (two or more systems sharing the same external storage device(s)). Prior to running diagnostics, verify that the 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 systems are located 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 codes are displayed, diagnose the first error code displayed.

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.For intermittent problems, check the error log; see “POST error messages” 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-FRU index” on page 143.

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

•Check for 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 symptom in “Symptom-to-FRU index” on page 143.

YES. Run the Diagnostic Programs. If necessary, refer to “Diagnostic programs and error messages” on page 25.

If you receive an error, 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.

Server features

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 microprocessors 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-swap capabilities

All models of the server support up to 10 slim-high disk drives. 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 has four 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 system 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-standard, 3.3 V, 168-pin, 8-byte, registered, dual inline memory modules (DIMMs). The memory controller also provides Chipkill™ memory protection. Chipkill memory protection is a technology that protects the system from component failure on a DIMM.

•System-management capabilities

The server comes with a Advanced System Management Processor. This processor enables you to manage the functions of the server locally and remotely. The Advanced System Management Processor also provides 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 selects 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, redundant 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 associated with this 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 programs 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 important features in server design are 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.

The following is an abbreviated list of the RAS features that the server supports.

This section provides basic troubleshooting information to help you resolve some common problems that might occur with the server.

If you cannot locate and correct the problem using the information in this section, refer to “Symptom-to-FRU index” on page 143 for more information.

Diagnostic tools overview

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

•POST beep codes, error messages, and error logs

The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem. 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

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

POST

When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test or POST.

If POST finishes without detecting any problems, a single beep sounds, the first screen of the operating system or application program 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 power-on password or administrator 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 first error 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 test.

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 system status messages from the Advanced System Management Processor.

To view the contents of the error logs, start the Configuration/Setup Utility program; then, select Event/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 hard disk drive, ignore 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.

Solving ServeRAID problems

This section describes the ServeRAID 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 controllers provide a Device Event Log that collects statistics on the number and types of events that occur on a selected physical drive. After correcting 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 messages

During power-on self-test (POST), the ServeRAID controller compares the stored configuration information to the configuration 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 controller detects a new drive that is not part of the current configuration, 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.

Diagnostics 15

Auto rearrange.

Explanation: Auto rearrange is enabled or disabled.

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

Battery-Backup Write Cache Not Responding

Explanation: BIOS code detected a bad or failed battery-backup write cache.

Action: Press F9 to remove the battery-backup write cache from the configuration, or press F10 to exit without change.

Battery-Backup Write Cache Replacement

Explanation: The ServeRAID controller detects that the battery-backup write cache is defective.

Action: Press F8 if you replaced the battery-backup write cache, or press F10 if you have not replaced the battery-backup write cache.

Configured drives are missing.

Explanation: When the ServeRAID controller detects that a previously configured drive is missing, the following message appears:

x online drives not responding

where x is the number of drives not responding. Example of a possible message: Online Drive on Channel 3 SCSI ID 3 is not responding.

Action: Press one of the following keys:

F2 – Detailed description. Press this key for a detailed description of the problem, such as the example message above.

F4 – Retry. Press this key after correcting a problem. For example, press F4 after you turn on the external storage enclosure that contains the physical drive.

F5 – Change the configuration and set the drives 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. 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 state does not necessarily mean that you need to replace the drive. Before you replace the drive, ensure that:

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.

After you perform these steps, if the physical drive does not function properly, replace the drive.

F10 – Continue booting without changing the configuration. Press this key to continue without change to the configuration.

16 Hardware Maintenance Manual: xSeries 250

Configured drives are not in the configured location.

Explanation: When the ServeRAID controller detects that a previously configured drive is present, but the drive is in a new location, the following message appears:

x online drive has been rearranged

where x is the number of drives that have been rearranged. Examples of possible messages are:

Online Drive on Channel 3 SCSI ID 4 moved to Channel 3 SCSI ID 3 Online Drive on Channel 3 SCSI ID 3 moved to Channel 3 SCSI ID 4

Action: Press one of the following keys:

F2 – Detailed description. Press this key for a detailed description of the problem, such as the example messages above.

F4 – Retry. Press this key after correcting a problem. For example, press F4 after you move the physical drive to its previously assigned location.

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 replace the drive, ensure that:

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.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.

F6 – Change the configuration and accept the rearrangement. Press this key to modify the configuration to match the current drive location. You might remove the hot-swap drives from the server for security or maintenance reasons. If you replace the drives but install them in different drive bays, you can press F6 to accept the new locations, and the ServeRAID controller will update the configuration.

F10 – Continue startup without changing the configuration. Press this key to continue without change to the configuration.
