Troubleshooting Tools

This chapter explains the system troubleshooting tools. It
explains how to
Use different types of tests
Set up tests for groups of selected modules

Interpret test results

Examine and interpret error logs
Use boot error messages
Use console status messages

Troubleshooting Tools

Using Tests

The system uses two types of tests to check system hardware
operation:

Power-up self-tests, which run a comprehensive test of the
system hardware

Subtests, which test individual modules that you choose

‘

Subtests can be individual tests or test scripts, which are
groups of individual tests. If you run a test script, you can
select one of several prepared scripts or create your own.

Using Slot Numbers in Test Commands and Error Messages
Test commands and error messages include slot numbers that
identify the hardware to which the test command or error
message refers.
The slot number for the system module and memory modules
is always 7. Figure 3-1 shows the slot numbers for the SCSI
and ThinWire controllers on the system module and the option
modules.

Slot number 0 refers

to the module in
option siot 0.

Slot number 1 refers

to the module in
option siot 1.

Slot number 2 refers

to the module in
option slot 2.

Slot numbers for system hardware

Troubleshooting Tools

Running Power-Up Self-Tests
The system runs a power-up self-test when you turn on the
system power. The monitor and diagnostic LEDs report any
errors the power-up self-test detects. To find the corrective
action for any error codes the power-up self-test reports, refer
to Chapter 4.
Note: If the monitor displays the message PDE3: x, where x
represents an option module slot number, the system contains

incompatible ROM chips. Upgrade the system ROM chips if the
PDE3: x message appears.

You can specify a quick or thorough power-up self-test script to
run when the system powers up.

The quick test script is a limited script that minimizes the
time until the system boots.

The thorough script runs an extensive check of system
hardware. The thorough power-up self-test script is most
useful for field service troubleshooting.

To select a power-up self-test script, use the setenv command
to set the testaction environment variable. Type setenv
testaction (q | t) and press Return.
v

Specify g to select the quick test.

Specify t to select the thorough test.

Troubleshooting Tools

3-3

Running Subtests
In addition to the power-up self-test, you can use subtests to
troubleshoot. Subtests run individual tests or test scripts.
Running Individual Tests
To run an individual test, type
t [-1] slot/test largl] larg2] larg3] . . .

When you type an individual test command,

Keplace slot with the slot number of the module to be
tested. Table 3-1 lists the slot numbers assigned to each
module.

Replace test with the name of the particular test you want
to run.

The optional extended arguments (arg-1 and so on) specify

individual test conditions. Refer to Appendix D for an

explanation of the arguments used for each test.

=

To run a test script once and then stop, type sh script,
where you replace script with the name of the test script
you want to run. Then press Return.

To have a test script run and keep repeating until you press
Ctrl-C, include the optional -1 parameter in the command.
Type sh -1 script, where you replace script with the name of
the test script you want to run. Then press Return.

Displaying Lists of Available Tests
To display all individual tests available for a specific module,
type t slot/?, where you replace slot with the slot number of the
module for which you want a test listing. Then press Return.
A list of tests similar to this sample listing of tests for the

" Interpreting Test Error Messages
For every error that a self-test detects, an error message
appears on the screen. Error messages appear in the following
format:
e

?TFL slot/test (code: description) [module].

?TFL indicates that an error occurred.

slot represents the slot number of the module that reported
the error.

test represents the individual test that failed.

code represents a code that indicates which part of the test

description represents a possible message that describes the

failed.

failure.
s

module represents the module identification number.,

For an explanation of individual system module and memory
module error messages, refer to Appendix D.
For an explanation of individual SCSI, Ethernet, and
TURBOchannel option error messages, refer to the
TURBOchannel Maintenance Guide.
This is a sample error message:
?TFL

7/dz/alrm

(bad

interrupt)

[KNO02-AA]

This error message states that the module in slot number 7, the
system module, failed the serial line silo alarm test.

The additional message (bad interrupt) indicates that the test
failed the interrupt operation.

Troubleshooting Tools

Using Error Logs
The system records events and errors in the ULTRIX error logs.
Use the memory error, error and status register, and system
overheat error logs to troubleshoot intermittent problems.
Note: The ULTRIX error logs are not the same as the test error logs
that appear when you use the erl console command. The test error log
is a record of errors reported by tests run in console mode.

The following paragraphs describe ULTRIX error log formats
and error log parts useful in troubleshooting.

Examining Error Logs
You must be in ULTRIX to examine error logs. At the ULTRIX
prompt, type /etc/uerf -R | more and press Return. A full
display of error log entries appears on the monitor.
The first part of each error log describes the type of error and
system conditions in effect when the error occurred. The last
part of each log provides specific information about the error
and its location.

The first part of all error logs is similar to this:

Table 4-2 to troubleshoot.

—

If the monitor has no display, refer to the TURBOchannel
Maintenance Guide to troubleshoot.

Run the system test. Type test and press Return. The
system test runs a comprehensive check of the system
hardware. If this test returns an error code, refer to
Table 4-1 to troubleshoot.

If none of these tests reports a problem, check the memory

modules. Refer to “Memory Modules” in Chapter 5 to

troubleshoot.

4-2

If the system still reports no errors, but the problem
persists, examine the error logs. Refer to “Using Error Logs
to Troubleshoot” later in this chapter to troubleshoot.

If the system reports no errors, but the printer, modem, or
alternate terminal does not operate properly, perform an
external loopback serial line test. Refer to “Troubleshooting
When a Printer, Modem, or Alternate Terminal Does Not
Operate Properly” later in this chapter to troubleshoot.

If the system fails to boot, use any console error messages
that appear on the monitor to troubleshoot. Refer to
Appendix E to interpret console error messages.

Identifying Failed FRUs

Interpreting Test Results
Use the error messages that appear on the monitor and on the
diagnostic LEDs to identify failed FRUs.

Interpreting Error Messages That Appear on the Monitor
Error messages on the monitor have the form
?TFL slot/test_name (n: description) [module]
s

slot represents the slot number of the FRU that reported
the failure.

test_ rname is the name of the individual test that failed.

The string (n: description) [module] includes additional
information that describes the error.

Table 4-1 shows the corrective action indicated by each test that
displays an error message on the monitor.
Interpreting LED Displays
In diagnostic LED displays, the number on the four leftmost
LEDs, as you face the back of the system, is the slot number of
the FRU that failed.

Repeat the RAM board test. If the system reports that the
new memory module is bad, replace the system module and

chassis.

If the system reports that not all the memory modules failed,

replace only those individual modules that the RAM board test
indicates are bad.
RAM board test

The RAM board test checks the operation of individual memory
modules. This test can take several minutes for each memory
module tested.
To run a RAM board test on all memory modules, type
t 7/mem * and press Return. The system then tests each
memory module separately.

To run a RAM board test on a single module, type
t 7/mem board and press Return. When you type this
command, replace board with the slot number of the memory
module you want to test.
RAM board test error messages use the format
?TFL 7/mem/code: board (x: description).

Enter decimal values as a string of decimal digits with
no leading zeros (for example, 123).

Enter octal values as a string of octal digits with a
leading zero (for example, 0177).
Enter hexadecimal values as a string of hexadecimal
digits preceded by Ox (for example, 0x3fD).
When reading or writing to memory, enter data as bytes,
halfwords, or words. Because a word is 4 bytes, successive
addresses referenced by a word are successive multiples
of 4. For example, the address following 0x80000004 is
0x80000008. An error occurs if you specify an address that
is not on a boundary for the data size vou are using.

Information About Using Console Commands

Rules for Typing Console Commands

‘

Use console commands when the system monitor displays the
prompt >>. When typing console commands, follow these rules:

Type uppercase and lowercase letters exactly as they
appear in command lines. The system recognizes uppercase
and lowercase letters as different input.

To enter commands, press Return after typing a command
message.

E-2

Enter number values as follows:
-

Enter decimal values as a string of decimal digits with
no leading zeros (for example, 123).

Enter octal values as a string of octal digits with a
leading zero (for example, 0177).

Enter hexadecimal values as a string of hexadecimal
digits preceded by Ox (for example, 0x3fY).

Enter binary values as a string of binary digits

preceded by Ob (for example, 0b1001).

When reading or writing to memory, you have a choice
of data sizes: byte, halfword, or word. Because a word
is 4 bytes, successive addresses referenced by a word
are successive multiples of 4. For example, the address
following 0x80000004 is 0x80000008. An error occurs if you
specify an address that is not on a boundary for the data
size you are using.

Console Commands Generated by Version PDE3 ROM Chips

‘

The following key combinations have an immediate effect in

console mode:

Ctrl-S freezes the screen display.

Ctrl-Q releases a frozen screen display.

Ctrl-C aborts a command.

Ctrl-U erases a partially typed command line.

Conventions Used in This Appendix

Letters in bold face type like this are to be typed exactly
as they appear.

Letters in italics like this are variables that you replace
with actual values. (Note that your help and menu screens
display these variables in all capital letters.)

Arguments enclosed in square brackets ([ ]) are optional.
Ellipses (...) follow an argument that can be repeated.
A vertical bar ( | ) separates choices for a given. You can
think of it as a symbol meaning or.

Parentheses enclose values of which you must select one.
For example, -(b | h | w) means enter -b or -h or -w.
