CHAPTER

Introduction to the Sun Fire V20z Server

The Sun Fire V20z server is an AMD Opteron™ processor-based enterprise-class 1U 2P server. The Sun Fire V20z server provides performance and value to an enterprise environment, offering signiﬁcantly better performance than current 32-bit Intelbased solutions. The AMD Opteron processor implements the x86-64 architecture, which delivers signiﬁcant memory capacity and bandwidth with twice the memory capacity and up to three times the memory bandwidth of existing x86 32-bit servers. The balanced server design maximizes overall performance through industryleading I/O options, and delivers compelling real-world workload performance.

The Sun Fire V20z server includes an embedded service processor, ﬂash memory, RAM, a separate Ethernet interface, and server management software. It comes equipped with superior server management tools for greater control and minimum total cost of ownership. You can use the command line interface or SNMP integration with third party frameworks to conﬁgure and manage the platform with the service processor. The dedicated service processor provides complete operating system independence and maximum availability of server management.

1.3 Server Management

Strong server management capabilities are crucial to maintaining mission-critical servers. Advance notiﬁcation of problems and rapid diagnosis and correction are critical functions to an environment in which a few servers bear most of the workload. The Sun Fire V20z server and its extensive server management capabilities lower costs by reducing failure and potentially eliminating hands-on management.

1.3.1 Service Processor

The Sun Fire V20z server includes a dedicated service processor for complete operating system independence and maximum availability of server management. The service processor (SP) is an embedded PowerPC providing the following:

■

Environmental monitoring of the platform (such as temperatures, voltages, fan speeds, and panel switches)

■

Alert messages when problems occur

■

Remote control of server operations (boot, shutdown, and reboot of the server’s operating system, turning the server’s power on and off, stopping the server’s boot process in BIOS, and upgrading the BIOS)

The service processor runs an embedded version of Linux, and all the server management functions are developed as standard Linux applications. Its sole purpose is to support server management; therefore, the full functionality of the Linux platform is not available in the service processor. Many familiar applications, such as ftp and telnet, are not provided as they are not required to support the server management feature set.

1.7 Integrated Mirroring

With traditional mirroring (or RAID1), a drive has its data duplicated on two different drives using either a hardware RAID controller or software (generally by means of the operating system). If either drive fails, the other continues to function as a single drive until the failed drive is replaced.

With integrated mirroring enhanced (IME) (also referred to as either Enhanced RAID1 or RAID1E), instead of only being able to use only two drives, you can use two to six drives, including the option of only using an odd number of drives. Instead of mirroring at the disk level, the data is mirrored in stripes across the drives. Thus, IME allows for more ﬂexibility with mirroring data.

Not all operating systems support RAID on the Sun Fire V20z server at this time. Refer to the Sun Fire V20z Server Release Notes, operating systems do not yet support the Sun Fire V20z RAID capabilities.

CHAPTER

Troubleshooting and Diagnostics

Before troubleshooting your speciﬁc server problem, collect the following

information:

■ What events occurred prior to the failure?

■ Was any hardware or software modiﬁed or installed?

■ Was the server recently installed or moved?

■ How long has the server exhibited symptoms?

■ What is the duration or frequency of the problem?

The guidelines in “Preventative Troubleshooting” on page 3-2 will help you to prevent problems from occurring and will make troubleshooting easier.

After you have assessed the problem and noted your current conﬁguration and

environment, you can choose from several ways to troubleshoot your Sun Fire

V20z server

■ Visually inspect your system as described in “Visually Inspecting Your System”

on page 3-3.

■ Execute the Troubleshooting Dump Utility as described in “Troubleshooting

Utility” on page 3-5.

■ Execute diagnostics tests as described in “Diagnostics” on page 3-5.

3-1

3.1 Preventative Troubleshooting

Creating and following procedures can help prevent problems and make troubleshooting easier.

Follow these guidelines for preventative troubleshooting:

■ Use uniform naming conventions for your servers, such as names that denote server

location. Uniform naming conventions help when you try to remember often overlooked details that can hold the key to resolving a crisis.

■ Use unique IDs or names for your devices. You can reduce the risk of components

competing for the same resource if you have a list. Use the server setup utility to check for conﬂicts.

■ Create a backup plan. Schedule backups based on the needs of your server. If data is

changed frequently, frequent backups are required. Maintain a library of backups based on your information restoring needs. Test your backups periodically to be sure that your data is correctly stored.

■ Use enterprise systems management tools to automate the following processes, or

manually track this information:

■ Check hard disk space periodically. It is recommended that hard drives have a

minimum of 15 percent of free space.

■ Keep historical data. You will not know that the CPU utilization has increased

50 percent if you do not know what it was initially. If you have problems, you can use the data to compare before and after scenarios. For example, you might want to know about the user, bus, and power utilization rates.

■ Keep a trend analysis so that you will know what to expect during certain

points in time. For example, if the CPU utilization rate always increases by 50 percent during certain hours, you will know that increase is normal for the server you are tracking.

■ Create a problem resolution notebook. When problems do occur, keep a log of the

actions you took to resolve them. This could help you solve the same problem more quickly in the future. This information can save a great deal of time in the future and ensure accuracy, especially when dealing with future part replacement.

■ Keep an updated network topology map in an accessible location. This will help

in troubleshooting networking problems.

3-2 Sun Fire V20z Server User Guide • March 2004

■ Most problems occur when something in the server has changed. When making

changes to your server, follow these guidelines:

■ Document the system settings. If the system conﬁguration will change, ﬁrst

obtain a record of the current system conﬁguration settings.

■ If possible, make changes one at a time to isolate problems if they should occur.

This enables you to maintain a controlled environment and reduces the scope of any troubleshooting. Record the results of each change, including any errors or informational messages.

■ Check for potential device conﬂicts before adding a new device. Check for any

potential version dependencies, especially with third party software.

3.2 Visually Inspecting Your System

Improperly set controls and loose or improperly connected cables are common causes of problems with hardware components. When investigating a system problem, ﬁrst check all the external switches, controls, and cable connections. See “External Visual Inspection” on page 3-3.

If this does not resolve your problem, then visually inspect the system’s interior hardware for problems such as a loose card, cable connector, or mounting screw. See “Internal Visual Inspection” on page 3-4.

3.2.1 External Visual Inspection

To visually inspect the external system, follow these steps:

1. Note the state of the system fault LED on the front of the server.

The system fault LED blinks when a severe system fault, such as an overvoltage condition or an upper temperature limit, is detected. See of the system fault LED.

2. Turn off the system and any attached peripherals (if applicable).

Verify that all power cables are properly connected to the system, the monitor, and

peripherals, and check their power sources.

4. Inspect connections to any attached devices including network cables, keyboard, monitor, and mouse, as well as any devices attached to the serial port.

Chapter 3 Troubleshooting and Diagnostics 3-3

FIGURE 1-1 for the location

3.2.2 Internal Visual Inspection

To visually inspect the internal system, follow these steps:

Note – Before proceeding, read the safety instructions in the Sun Fire V20z Server Safety

and Compliance Guide, 816-7190-xx, for your system.

1. Shut down the operating system, if necessary, and turn off the platform power on the front of the server.

2. Turn off the AC power on the back of the server.

3. Turn off including any attached peripherals, but do not disconnect the power cables.

4. Remove the cover, following the procedures in

Safety Guidelines (Before You

Remove the Cover) on page 4-2.

Caution – Some components, such as the heatsink, can become extremely hot during system operations. Allow these components to cool before handling them.

5. Verify that the components are fully seated in their sockets or connectors and that sockets are clean.

6. Check all cable connectors inside the system to verify that they are ﬁrmly attached to their appropriate connectors.

7. Replace the cover.

8. Reconnect the system and any attached peripherals to their power sources, and turn them on.

3.4.4 Running Diagnostic Tests

When running tests, you can choose to execute all tests or specify a speciﬁc module for which to run tests. The following options are available:

■ Run tests individually or collectively

■ Choose the type (by module or name) of tests to run

■ Determine the sequence in which the tests are run (using scripts)

■ View status messages about the success of the tests

You can run these tests on the machine on which you obtained them. You must have the appropriate permissions to run these commands.

3-10 Sun Fire V20z Server User Guide • March 2004

To run the diagnostics tests, type the following command:

# diags run tests option

Where the option is one of the following:

Option Description

-n test_name

-m module

-a

To run one test at a time, replace test_name with the name of the test. You can specify more than one test by listing test names with a space between them.

To r un a batch of tests by module, replace module with the name of the test module.

Use this option to run all available diagnostics tests.

For example, if you suspect that you are having voltage problems, run the voltage module diagnostic tests:

# diags run tests -m voltage

Refer to Appendix C for more information about using these command options.

You can write scripts for additional control over the sequencing and timing of the tests. For example, you could write a shell script to repeat a test a speciﬁed number of times.

3.4.5 Viewing Test Results

After a test successfully executes, the status returns. When a test receives an error, it reports the error and continues to run any remaining tests submitted with the command.

The following output is typically generated for all diagnostics tests:

■ Submitted Test Name

■ Test Handle (a dynamically assigned unique number used by the diagnostics

application to identify a running test)

■ Test Result (Passed, Failed)

■ Details (for example, Failure Details, Tests Details)

Specifying the -v | --verbose option when running the test displays additional data about a test. See Appendix C for more details.

For example, test details may include high, nominal, and low values.

Chapter 4 Maintaining the Server 4-29

The two halves of the 5-pin SCSI backplane power cable connector (1) are secured with a hook.

The 68-pin SCSI ribbon cable (2) has no locking mechanism.

The small ﬂat cables (3-7) are attached using two different types of zero insertion force (ZIF) cable connectors. Because of their small size, it may be difﬁcult to distinguish one connector type from the other.

Refer to Figure 4-40 for the methods used to release cables from the various types of connector.

Caution – Use caution when removing cables as they are fragile—the small ﬂat

ﬂexible cables and cable connectors are extremely sensitive.

5. Unfasten the two securing screws and remove the heatsink securing clip.

FIGURE 4-43 Removing the Securing Clip and Heatsink

6. Twist the heatsink slightly to the right or left, in order to break the seal with the thermal grease.

7. Lift the heatsink away from the CPU.

Note – The heatsink can become extremely hot. Be sure it has had sufﬁcient time to

cool before handling.

8. Place the heatsink upside down on a ﬂat surface to prevent the thermal grease from contaminating other components.

9. Pull the socket release lever up to the fully open, perpendicular position.

10. Lift the CPU out of the socket, leaving the release lever in the open position.

FIGURE 4-44 Removing a CPU from its Socket

4.4.14.2 Installing a CPU and Heatsink

1. Unpack the new CPU.

Caution – Observe the appropriate ESD precautions.

2. Ensure that the socket release lever is in the fully open, perpendicular position.

3. Align the small triangle, on the corner of the CPU, with the triangle on the corner of the socket.

FIGURE 4-45 Installing a CPU in its Socket

4. Insert the CPU into the socket.

Note – If correctly aligned, the CPU should easily insert into the socket. If more

than minimal resistance is felt, stop and recheck the alignment. Forcing a misaligned CPU into the socket will permanently damage the device.

5. When the CPU is fully seated in the socket, rotate the socket release lever until it snaps into place, securing the CPU in the socket.

6. Use the syringe to apply approximately 0.1 ML/CC of thermal grease in a circular pattern to the top of the CPU.

7. Gently distribute the thermal grease and remove any excess so that only an extremely thin, uniform layer remains. If any voids or crevices appear that could lead to air pockets, reapply the grease until you achieve a thin but compact consistency.

8. Use an alcohol pad to remove all thermal grease from the bottom of the heatsink.

9. Inspect the heatsink for dust and lint. Clean if necessary.

Chapter 4 Maintaining the Server 4-33

10. Ensure the foam strip under the heatsink area is intact and has not been removed, loosened, or damaged. This foam strip is critical to proper air ﬂow.

11. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.

Caution – If the heatsink is moved too much during its installation, the layer of

thermal grease may become uneven, leading to component damage.

12. After the heatsink is correctly aligned, reinstall the heatsink clips so that the longer tab points toward the fans.

13. Tighten the clip securing screws.

14. Replace the center air duct and the system cover.

Note – Check the routing of all cables for obstructions before reinstalling the cover.

BIOS POST Codes

Typically, the BIOS displays warning or error messages on the video display in the event of hardware or conﬁguration errors. However, in some cases the error may be so severe that the BIOS halts immediately, or BIOS might be unable to initialize video. In these cases, it can be useful to determine the last Power On Self Test (POST) task that the BIOS was executing. This is indicated by the value written to port 80.

For information about retrieving the last port 80 post code using the sp get port80 command, refer to the Sun Fire V20z Server Management Guide, for details.

You can also retrieve the last 10 port 80 post codes using the operator panel. Refer to the Sun Fire V20z Server Management Guide,

817-5249-xx, for more details about using

the operator panel menus.
