Gathering Service Information
The first step in determining the cause of a problem with the server is to gather
information from the service-call paperwork or the onsite personnel. Use the
following general guideline steps when you begin troubleshooting.
To gather service information:
1. Collect information about the following items:
■
■
■
■
■
Events that occurred prior to the failure
Whether any hardware or software was modified or installed
Whether the server was recently installed or moved
How long the server exhibited symptoms
The duration or frequency of the problem
2. Document the server settings before you make any changes.
If possible, make one change at a time in order to isolate potential problems. In
this way, you can maintain a controlled environment and reduce the scope of
troubleshooting.
3. Take note of the results of any change that you make. Include any errors or
informational messages.
4. Check for potential device conflicts before you add a new device.
5. Check for version dependencies, especially with third-party software.

Internally Inspecting the Server
To perform a visual inspection of the internal system:
1. Choose a method for shutting down the server from main power mode to
■
Graceful shutdown – Use a ballpoint pen or other stylus to press and release
the Power button on the front panel. This causes Advanced Configuration and
Power Interface (ACPI) enabled operating systems to perform an orderly
shutdown of the operating system. Servers not running ACPI-enabled
operating systems will shut down to standby power mode immediately.
■
Emergency shutdown – Use a ballpoint pen or other stylus to press and hold
the Power button for four seconds to force main power off and enter standby
power mode.
Caution – Performing an emergency shutdown can cause open files to become
corrupt. Use an emergency shutdown only when necessary.
When main power is off, the Power/OK LED on the front panel will begin
flashing, indicating that the server is in standby power mode.
Caution – When you use the Power button to enter standby power mode, power is
still directed to service processor and power supply fans, indicated when the
Power/OK LED is flashing. To completely power off the server, you must disconnect
the AC power cords from the back panel of the server.

Note – The server must be in standby power mode for viewing the internal LEDs.
You can hold down the Locate button on the server back panel or front panel for
5 seconds to initiate a “push-to-test” mode that illuminates all other LEDs both
inside and outside of the chassis for 15 seconds.
4. Verify that there are no loose or improperly seated components.
5. Verify that all cable connectors inside the system are firmly and correctly
attached to their appropriate connectors.
6. Verify that any after-factory components are qualified and supported.
For a list of supported PCI cards and DIMMs, refer to your server’s service
manual.
7. Check that the installed DIMMs comply with the supported DIMM population

SunVTS software has a sophisticated graphical user interface (GUI) that provides
test configuration and status monitoring. The user interface can be run on one
system to display the SunVTS testing of another system on the network. SunVTS
software also provides a TTY-mode interface for situations in which running a GUI
is not possible.
SunVTS Documentation
For the most up-to-date information on SunVTS software, go to:
Diagnosing Server Problems With the Bootable
Diagnostics CD
SunVTS 6.4 or later software is preinstalled on your server. The server is also
shipped with the Bootable Diagnostics CD. This CD is designed so that the server
will boot from the CD. This CD boots and starts SunVTS software. Diagnostic tests
run and write output to log files that the service technician can use to determine the
problem with the server.
Requirements
■
To use the diagnostics CD you must have a keyboard, mouse, and monitor
attached to the server on which you are performing diagnostics, or available
through a remote KVM.

Using the Bootable Diagnostics CD
To use the diagnostics CD to perform diagnostics:
1. With the server powered on, insert the CD into the DVD-ROM drive.
2. Reboot the server, and press F2 during the start of the reboot so that you can
change the BIOS setting for boot-device priority.
3. When the BIOS Main menu appears, navigate to the BIOS Boot menu.
Instructions for navigating within the BIOS screens appear on the BIOS screens.
4. On the BIOS Boot menu screen, select Boot Device Priority.
The Boot Device Priority screen appears.
5. Select the DVD-ROM drive to be the primary boot device.
6. Save and exit the BIOS screens.
7. Reboot the server.
When the server reboots from the CD in the DVD-ROM drive, the Solaris
Operating System boots and SunVTS software starts and opens its first GUI
window.
8. In the SunVTS GUI, press Enter or click the Start button when you are
prompted to start the tests.
The test suite will run until it encounters an error or the test is completed.
Note – The CD will take approximately nine minutes to boot.
9. When SunVTS software completes the test, review the log files generated
during the test.
SunVTS provides access to four different log files:
■
SunVTS test error log contains time-stamped SunVTS test error messages. The
log file path name is /var/opt/SUNWvts/logs/sunvts.err. This file is not
created until a SunVTS test failure occurs.
■
SunVTS kernel error log contains time-stamped SunVTS kernel and SunVTS
probe errors. SunVTS kernel errors are errors that relate to running SunVTS,
and not to testing of devices. The log file path name is
/var/opt/SUNWvts/logs/vtsk.err. This file is not created until SunVTS
reports a SunVTS kernel error.
■
SunVTS information log contains informative messages that are generated
when you start and stop the SunVTS test sessions. The log file path name is
/var/opt/SUNWvts/logs/sunvts.info. This file is not created until a
SunVTS test session runs.

■
Solaris system message log is a log of all the general Solaris events logged by
syslogd. The path name of this log file is /var/adm/messages.
a. Click the Log button.
The Log file window is displayed.
b. Specify the log file that you want to view by selecting it from the Log file
window.
The content of the selected log file is displayed in the window.
c. With the three lower buttons you can perform the following actions:
■
■
■
Print the log file – A dialog box appears for you to specify your printer
options and printer name.
Delete the log file – The file remains on the display, but it will not be
available the next time you try to display it.
Close the Log file window – The window is closed.
Note – If you want to save the log files: When you use the Bootable Diagnostics
CD, the server boots from the CD. Therefore, the test log files are not on the server’s
hard disk drive and they will be deleted when you power cycle the server. To save
the log files, you must save them to a removable media device or FTP them to
another system.

CHAPTER
3
Troubleshooting DIMM Problems
This chapter describes how to detect and correct problems with the server’s Dual
Inline Memory Modules (DIMM)s. It includes the following sections:
■
■
■
■
DIMM Population Rules
The DIMM population rules for the server are as follows:
■
Each CPU can support a maximum of eight DIMMs.
■
The DIMM slots are paired and the DIMMs must be installed in pairs (0-1, 2-3, 4-
or white to indicate which slots are paired by matching colors.
■
■
DIMMs are populated starting from the outside (away from the CPU) and
working toward the inside.
CPUs with only a single pair of DIMMs must have those DIMMs installed in that
■
■
Only DDR2 800 Mhz, 667Mhz, and 533Mhz DIMMs are supported.
Each pair of DIMMs must be identical (same manufacturer, size, and speed).

DIMM Replacement Policy
Replace a DIMM when one of the following events takes place:
■
The DIMM fails memory testing under BIOS due to Uncorrectable Memory Errors
(UCEs).
■
UCEs occur and investigation shows that the errors originated from memory.
In addition, a DIMM should be replaced whenever more than 24 Correctable
Errors (CEs) originate in 24 hours from a single DIMM and no other DIMM is
showing further CEs.
■
If more than one DIMM has experienced multiple CEs, other possible causes of
CEs have to be ruled out by a qualified Sun Support specialist before replacing
any DIMMs.
Retain copies of the logs showing the memory errors per the above rules to send to
Sun for verification prior to calling Sun.
How DIMM Errors Are Handled by the
System
This section describes system behavior for the two types of DIMM errors: UCEs and
CEs, and also describes BIOS DIMM error messages.
Uncorrectable DIMM Errors
For all operating systems (OS’s), the behavior is the same for UCEs:
1. When an UCE occurs, the memory controller causes an immediate reboot of the
system.
2. During reboot, the BIOS checks the Machine Check registers and determines that
the previous reboot was due to an UCE, then reports this in POST after the
memtest stage:
A Hypertransport Sync Flood occurred on last boot

21 to 25
BIOS off-lined faulty DIMMs from system memory space and reported
them. Each DIMM of a pair is being reported, since hardware UCE
evidence cannot lead BIOS any further than detection of a faulty pair.
Correctable DIMM Errors
If a DIMM has 24 or more correctable errors in 24 hours, it is considered defective
and should be replaced.
At this time, CEs are not logged in the server’s system event logs. They are reported
or handled in the supported OS’s as follows:
■
Windows Server:
a. A Machine Check error-message bubble appears on the task bar.
b. The user must manually open Event Viewer to view errors. Access Event
Viewer through this menu path:
Start-->Administration Tools-->Event Viewer
c. The user can then view individual errors (by time) to see details of the error.
Solaris:
■
Solaris FMA reports and (sometimes) retires memory with correctable Error
Correction Code (ECC) errors. See your Solaris Operating System documentation
for details. Use the command:
fmdump -eV

to view ECC errors
Linux:
■
The HERD utility can be used to manage DIMM errors in Linux. See the x64
Servers Utilities Reference Manual for details.
■
If HERD is installed, it copies messages from /dev/mcelogto
/var/log/messages.
■
If HERD is not installed, a program called mcelog copies messages from
/dev/mcelog to /var/log/mcelog.
BIOS DIMM Error Messages
The BIOS displays and logs the following DIMM error messages:
NODE-n Memory Configuration Mismatch
The following conditions will cause this error message:
■
The DIMMs mode is not paired (running in 64-bit mode instead of 128-bit
mode).
■
■
■
■
■
■
■
■
■
■
The DIMMs’ speed is not same.
The DIMMs do not support ECC.
The DIMMs are not registered.
The MCT stopped due to errors in the DIMM.
The DIMM module type (buffer) is mismatched.
The DIMM generation (I or II) is mismatched.
The DIMM CL/T is mismatched.
The banks on a two-sided DIMM are mismatched.
The DIMM organization is mismatched (128-bit).
The SPD is missing Trc or Trfc information.
DIMM Fault LEDs
When you press the Press to See Fault button on the motherboard or the mezzanine
board, LEDs next to the DIMMs flash to indicate that the system has detected 24 or
more CEs in a 24-hour period on that DIMM.

Note – The DIMM Fault and Motherboard Fault LEDs operate on stored power for
up to a minute when the system is powered down, even after the AC power is
disconnected, and the motherboard (or mezzanine board) is out of the system. The
stored power lasts for about half an hour.
Note – Disconnecting the AC power removes the fault indication. To recover fault
information look in the SP SEL, as described in the Sun Integrated Lights Out Manager
2.0 User's Guide.
■
■
DIMM fault LED is off – The DIMM is operating properly.
DIMM fault LED is flashing (amber) – At least one of the DIMMs in this DIMM
pair has reported 24 CEs within a 24-hour period.
■
Motherboard Fault LED on mezzanine is on – There is a fault on the motherboard.
This LED is there because you cannot see the motherboard LEDs when the
mezzanine board is present.
Note – The Motherboard Fault LED operates independently of the Press to See Fault
button, and does not operate on stored power.
See FIGURE 3-1 for the locations of DIMMs and LEDs on the motherboard. See
FIGURE 3-2 for the locations of DIMMs and LEDs on the mezzanine board.

Isolating and Correcting DIMM ECC
Errors
If your log files report an ECC error or a problem with a DIMM, complete the steps
below until you can isolate the fault.
In this example, the log file reports an error with the DIMM in CPU0, slot 7. The
fault LEDs on CPU0, slots 6 and 7 are on.
To isolate and correct DIMM ECC errors:
1. If you have not already done so, shut down your server to standby power mode
and remove the cover.
18
Sun Fire X4140, X4240, and X4440 Servers Diagnostics Guide • August 2008

3. Press the PRESS TO SEE FAULT button, and inspect the DIMM fault LEDs. See
A flashing LED identifies a component with a fault.
■
For CEs, the LEDs correctly identify the DIMM where the errors were detected.
■
For UCEs, both LEDs in the pair flash if there is a problem with either DIMM
in the pair.
Note – If your server is equipped with a mezzanine board, the motherboard DIMMs
and LEDs will be hidden beneath it. However, the Motherboard Fault LED lights to
indicate that there is a problem on the motherboard (only while AC power is still
connected). If the Motherboard Fault LED on the mezzanine board lights, remove
the mezzanine board as described in your server’s service manual, and inspect the
LEDs on the motherboard.
4. Disconnect the AC power cords from the server.
Caution – Before handling components, attach an ESD wrist strap to a chassis
ground (any unpainted metal surface). The system’s printed circuit boards and hard
disk drives contain components that are extremely sensitive to static electricity.
Note – To recover fault information look in the SP SEL, as described in the Sun
Integrated Lights Out Manager 2.0 User's Guide.
5. Remove the DIMMs from the DIMM slots in the CPU.
Refer to your server’s service manual for details.
6. Visually inspect the DIMMs for physical damage, dust, or any other
contamination on the connector or circuits.
7. Visually inspect the DIMM slot for physical damage. Look for cracked or
broken plastic on the slot.
8. Dust off the DIMMs, clean the contacts, and reseat them.
Caution – Use only compressed air to dust DIMMs.
9. If there is no obvious damage, replace any failed DIMMs.
For UCEs, if the LEDs indicate a fault with the pair, replace both DIMMs. Ensure
that they are inserted correctly with ejector latches secured.
10. Reconnect AC power cords to the server.

Power-On Self-Test (POST)
The system BIOS provides a rudimentary power-on self-test. The basic devices
required for the server to operate are checked, memory is tested, the LSI 1064 disk
controller and attached disks are probed and enumerated, and the two Intel dual
Gigabit Ethernet controllers are initialized.
The progress of the self-test is indicated by a series of POST codes. These codes are
displayed at the bottom right corner of the system’s VGA screen (once the self-test
has progressed far enough to initialize the system video). However, the codes are
displayed as the self-test runs and scroll off of the screen too quickly to be read. An
alternate method of displaying the POST codes is to redirect the output of the
How BIOS POST Memory Testing Works
The BIOS POST memory testing is performed as follows:
1. The first megabyte of DRAM is tested by the BIOS before the BIOS code is
shadowed (that is, copied from ROM to DRAM).
2. Once executing out of DRAM, the BIOS performs a simple memory test (a
write/read of every location with the pattern 55aa55aa).
Note – Enabling Quick Boot causes the BIOS to skip the memory test. See
“Changing POST Options” on page 28 for more information.
Note – Because the server can contain up to 64 MB of memory (128 MB for the
X4440), the memory test can take several minutes. You can cancel POST testing by
pressing any key during POST.
3. The BIOS polls the memory controllers for both correctable and uncorrectable
memory errors and logs those errors into the service processor.

4. On the Boot Settings Configuration screen, there are several options that you
can enable or disable:
■
Quick Boot – This option is disabled by default. If you enable this, the BIOS
skips certain tests while booting, such as the extensive memory test. This
decreases the time it takes for the system to boot.
■
■
Quiet Boot – This option is disabled by default. If you enable this, the Sun
Microsystems logo is displayed instead of POST codes.
Add On ROM Display Mode – This option is set to Force BIOS by default.
This option has effect only if you have also enabled the Quiet Boot option, but
it controls whether output from the Option ROM is displayed. The two settings
for this option are as follows:
■
Force BIOS – Remove the Sun logo and display Option ROM output.
■
Keep Current – Do not remove the Sun logo. The Option ROM output is not
displayed.

Boot Num-Lock – This option is On by default (keyboard Num-Lock is turned
on during boot). If you set this to off, the keyboard Num-Lock is not turned on
during boot.
Wait for F1 if Error – This option is disabled by default. If you enable this, the
system will pause if an error is found during POST and will only resume when
you press the F1 key.

Making a Serial Connection to the SP
To make a serial connection to the SP:
1. Connect a serial cable from the RJ-45 Serial Management port on server to a
terminal device.
2. Press ENTER on the terminal device to establish a connection between that
terminal device and the ILOM SP.
Note – If you are connecting to the serial port on the SP before it has been powered
up or during its power-up sequence, you will see boot messages.
The service processor eventually displays a login prompt. For example:
SUNSP0003BA84D777 login:
The first string in the prompt is the default host name for the ILOM SP. It consists
of the prefix SUNSPand the MAC address of the ILOM SP. The MAC address for
each ILOM SP is unique.
3. Log in to the SP and type the default user name, root, with the default
password, changeme.
Once you have successfully logged in to the SP, it displays its default command
prompt.

If the clock settings change, the change is reflected in the time stamps.
When the service processor reboots, the SP clock is set to Thu Jan 1 00:00:00 UTC
1970. The SP reboots as a result of the following:
■
■
■
A complete system unplug/replug power cycle
An IPMI command; for example, mc reset cold
A command-line interface (CLI) command; for example, reset /SP

SP
An SP firmware upgrade
After an SP reboot, the SP clock is changed by the following events:
■
When the host is booted. The host’s BIOS unconditionally sets the SP time to that
indicated by the host’s RTC. The host’s RTC is set by the following operations:
■
When the host’s CMOS is cleared as a result of changing the host’s RTC battery
or inserting the CMOS-clear jumper on the motherboard. The host’s RTC starts
at Jan 1 00:01:00 2002.
■
When the host’s operating system sets the host’s RTC. The BIOS does not
consider time zones. Solaris and Linux software respect time zones and will set
the system clock to UTC. Therefore, after the OS adjusts the RTC, the time set
by the BIOS will be UTC.
■
When the user sets the RTC using the host BIOS Setup screen.
■
■
Continuously via NTP if NTP is enabled on the SP. NTP jumping is enabled to
recover quickly from an erroneous update from the BIOS or user. NTP servers
provide UTC time. Therefore, if NTP is enabled on the SP, the SP clock will be in
UTC.

Handling of Uncorrectable Errors
This section lists facts and considerations about how the server handles
uncorrectable errors.
Note – The BIOS ChipKill feature must be disabled if you are testing for failures of
multiple bits within a DRAM (ChipKill corrects for the failure of a four-bit wide
DRAM).
■
The BIOS logs the error to the SP system event log (SEL) through the board
management controller (BMC).
■
■
■
The SP's SEL is updated with the failing DIMM pair's particular bank address.
The system reboots.
The BIOS logs the error in DMI.
53
Download from Www.Somanuals.com. All Manuals Search And Download.
Note – If the error is on low 1MB, the BIOS freezes after rebooting. Therefore, no
DMI log is recorded.
■
An example of the error reported by the SEL through IPMI 2.0 is as follows:
■
When low memory is erroneous, the BIOS is frozen on pre-boot low memory
test because the BIOS cannot decompress itself into faulty DRAM and execute
the following items:
ipmitool> sel list

200 | 08/26/2005 | 11:36:12 | System Firmware Error | No usable system memory
300 | 08/26/2005 | 11:36:12 | Memory | Memory Device Disabled | CPU 0 DIMM 0
■
When the faulty DIMM is beyond the BIOS's low 1MB extraction space, proper
boot happens:

The BIOS does detect some errors that are
announced during POST as POST codes on
the bottom right corner of the display on the
serial console and on the video display. Some
POST codes are forwarded to the SP for
logging.
The POST codes do not come out in
sequential order and some are repeated,
because some POST codes are issued by code
in add-in card BIOS expansion ROMs.
In the case of early POST failures (for
example, the BSP fails to operate correctly),
BIOS just halts without logging.
For some other POST failures subsequent to
memory and SP initialization, the BIOS logs a
message to the SP’s SEL.
