SunVTS Overview

This chapter contains an overview of the SunVTS™diagnostic tool.
This chapter contains the following topics:

■ SunVTS Description—page 2-1

■ SunVTS Operation—page 2-2

2.1 SunVTS Description

The SunVTS software executes multiple diagnostic hardware tests from a single user
interface. SunVTS verifies the configuration, functionality, and reliability of most
hardware controllers and devices.

The SunVTS software can be used in both the Common Desktop Environment (CDE)
and the OPEN LOOK graphical user interface (GUI) environments, or from a TTY
interface.

Within the CDE and OPEN LOOK GUI environments, test parameters can be set
quickly and easily by pointing and clicking a mouse button.

With a TTY interface, the SunVTS software is used from a terminal or modem
attached to a serial port. Data is input through the keyboard, rather than with a
mouse, and only one screen of information is displayed at a time.

3.2 Pre-POST Preparation

Pre-POST preparation includes:

■ Setting up a tip connection to another workstation or terminal to view POST

progress and error messages. See Section 3.2.1, “Setting Up a Tip Connection” on
page 3-3.

■ Verifying baud rates between a workstation and a monitor or a workstation and a

terminal. See Section 3.2.2, “Verifying the Baud Rate” on page 3-4.

If a terminal or a monitor is not connected to serial port A (default port) of a
workstation or server to be tested, the keyboard LEDs are used to determine error
conditions. See Section 3.7, “System and Keyboard LEDs” on page 3-22

3.2.1 Setting Up a Tip Connection

A tip connection enables a remote shell window to be used as a terminal to display
test data of a system being tested. Serial port A or serial port B of a tested system
unit is used to establish the tip connection between the system unit being tested and
another Sun workstation monitor or TTY-type terminal. The tip connection is used in
a SunOS

To set up a tip connection:

1. See
another Sun workstation using a serial null modem cable (connect cable pins 2-3,
3-2, 7-20, and 20-7).

2. At the other Sun workstation, check the /etc/remote file by changing to the
/etc directory and then editing the remote file:

hardwire:/ dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:

Note – The example shows connection to serial port B.

3. To use serial port A:
a. Copy and paste the serial port B remote file.
b. Modify the serial port B remote file as follows:

hardwire:\ dv=/dev/term/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:

Chapter 3 Power-On Self-Test 3-3

4. In a shell window on the Sun workstation, type tip hardwire.

hostname% tip hardwire
connected

Note – The shell window is now a tip window directed to the serial port of the

system unit being tested. When power is applied to the system unit being tested,
POST messages will be displayed in this window.

5. When POST is completed, disconnect the tip window as follows:
a. Open a shell window.
b. Type ps -a to view the active tip line and process ID (PID) number.
c. Type the following to kill the tip hardwire process.

% kill -9 PID#

3.2.2 Verifying the Baud Rate

To verify the baud rate between the system unit being tested and a terminal or
another Sun workstation monitor:

1. Open a Shell window.

2. Type eeprom.

3. Verify the following serial port default settings as follows:

ttyb-mode = 9600,8,n,1
ttya-mode = 9600,8,n,1

Note – Ensure that the settings are consistent with TTY-type terminal or

workstation monitor settings.

3-4 Sun Ultra 60 Service Manual • August 2001

3.3 Initializing POST

POST is initilized in two ways:

■ By setting the diag-switch? to true and the diag-level to max or min,

followed by power cycling the system unit

■ By simultaneously pressing the keyboard Stop and D keys while power is applied

to the system unit

To set the diag-switch? to true and power cycle the system unit:

1. At the system prompt, type:

ok setenv diag-switch? true

2. At the keyboard, power cycle the system unit by simultaneously pressing the
Shift key and the power-on key (

b. The monitor power-on indicator flashes on and off.
c. The keyboard Caps Lock key indicator flashes on and off.

4. When the POST is complete, type the following at the system prompt:

ok setenv diag-switch? false

3.4 Maximum and Minimum Levels of POST

Two levels of POST are available: maximum (max) level and minimum (min) level.
The system initiates the selected level of POST based upon the setting of
diag-level, a NVRAM variable.

The default setting for diag-level is max. An example of a max level POST output
on serial port A is provided in Section 3.4.1, “diag-level Variable Set to max” on
page 3-7 An example of a min level POST output on serial port A is provided in
Section 3.4.2, “diag-level Variable Set to min” on page 3-14.

To set the diag-level variable to min, type:

ok setenv diag-level min

To return to the default setting

ok setenv diag-level max

3.4.1 diag-level Variable Set to max

When the diag-level variable is set to max, POST enables an extended set of
diagnostic-level tests. This mode requires approximately 2 minutes and 15 seconds
to complete (with 128 Mbytes of DIMM installed).

3.4.3 POST Progress and Error Reporting

While POST is initialized, the Caps Lock key on the Sun Type-5 keyboard flashes on
and off to indicate that POST tests are being executed. Additional POST progress
indications are also visible when a TTY-type terminal or a tip line is connected
between serial port A (default port) of the system being tested and a POST
monitoring system.

3-18 Sun Ultra 60 Service Manual • August 2001

If an error occurs during the POST execution, the keyboard Caps Lock key indicator
stops flashing and an error code is displayed using the Caps Lock, Compose, Scroll
Lock, and Num Lock key indicators. The error code indicates a particular system
hardware failure.

Note – An error code may only be visible for a few seconds. Observe the Caps Lock,

Compose, Scroll Lock, and Num Lock key indicators closely while POST is active.

In most cases, POST also attempts to send a failure message to the POST monitoring
system.

CODE EXAMPLE 3-3 identifies the typical appearance of a failure message. If a

keyboard error code is displayed, determine the meaning of the error code by
comparing the keyboard error code pattern to the corresponding error code meaning
listed in

TABLE 3-2.

Note – The system unit does not automatically boot if a POST error occurs; it halts

at the ok prompt to alert the user of a failure.

3.5 Bypassing POST

POST can be disabled and thereby bypassed. To bypass POST:

1. Prior to powering on the system, press and hold the Stop key on the keyboard
(

FIGURE 3-2).

2. With the Stop key pressed, turn on the system by pressing the power-on key.

Chapter 3 Power-On Self-Test 3-21

3.6 Additional Keyboard Control Commands

■ Stop Key

If the diag-level is set to either max or min and the diag-level switch? variable
is set to true and POST is not to be executed when the system is powered on, press
and hold the keyboard Stop key and press the keyboard power-on key.

Note – Press and hold the Stop key for approximately 5 seconds.

■ Stop and N Keys

To set the system NVRAM parameters to the original default settings, press and hold
the Stop and N keys before powering on the system. Continue to hold the Stop and
N keys until the system banner displays on the monitor.

3.7 System and Keyboard LEDs

While POST is executing and making progress, the Caps Lock key LED blinks while
the rest of the LEDs are off. If POST finds an error, a pattern is encoded in the LEDs

3.8 Initializing Motherboard POST

To initialize the motherboard POST:

1. Power off the system unit.

2. At the keyboard, simultaneously press and hold the Stop and D keys and press
the power-on key.

Note – Video output is disabled while POST is initialized.

Note – If the POST output results are to be viewed, a tip connection must be set up.

See Section 3.2.1, “Setting Up a Tip Connection” on page 3-3.

3. Verify the keyboard LEDs light to confirm the system is in the POST mode and
the keyboard Caps Lock key LED flashes on and off to indicate the system has
enabled POST.

4. If a failure occurs during POST, a keyboard key LED other than the Caps Lock
key LED may light, indicating a failed system component.

See Section 3.7, “System and Keyboard LEDs” on page 3-22.

5. If the Caps Lock key LED fails to flash after the Stop and D keys are pressed,
POST has failed.

See Section 3.7, “System and Keyboard LEDs” on page 3-22.

Note – The most probable cause of this type of failure is the motherboard. However,

optional system components could also cause POST to fail.

6. Before replacing the motherboard, remove any optional components, such as PCI
cards and memory, and repeat the POST.

Note – Non-optional components such as DIMMs, the motherboard, the power

supply, and the keyboard must be installed for POST to execute properly. Removing
the optional system components and retesting the system unit isolates the possibility
that those components are the cause of the failure.

7. To receive additional POST failure information, establish a tip connection.

See Section 3.2.1, “Setting Up a Tip Connection” on page 3-3.

4.1 Power-On Failure

This section provides examples of power-on failure symptoms and suggested
actions.

Symptom

The system unit does not power up when the keyboard power switch is pressed.

Action

Check the keyboard connection. Ensure that the keyboard is properly connected to
the system unit. Check the AC power cord. Ensure that the AC power cord is
properly connected to the system unit and to the wall receptacle. Verify that the wall
receptacle is supplying AC power to the system unit.

Press the power switch. If the system unit powers on, the keyboard may be defective
or the system unit is unable to accept the keyboard power-on signal. Power off the
system unit and press the keyboard power-on switch again. If the system unit
powers on, no further action is required. If the system unit does not power on, the
CPU module may not be properly seated. Inspect the CPU module for proper
seating. If the system unit powers on, no further action is required. If the system unit
does not power on, the keyboard may be defective.Connect a spare Sun Type-5
keyboard to the system unit and press the power-on key.

If the wall receptacle AC power has been verified, the CPU module is properly
seated, and a spare Sun Type-5 keyboard has been connected to the system unit and
the power-on key has been pressed but the system unit does not power up, the
system unit power supply may be defective. See Section 4.4, “Power Supply Test” on
page 4-5.

Symptom

The system unit attempts to power up but does not boot or initialize the monitor.

4-2 Sun Ultra 60 Service Manual • August 2001

Action

Press the keyboard power-on key and watch the keyboard. The keyboard LEDs
should light briefly and a tone from the keyboard should be heard. If a tone is not
heard or if the keyboard LEDs do not light briefly, the system unit power supply
may be defective. See Section 4.4, “Power Supply Test” on page 4-5. If a keyboard
tone is heard and the keyboard LEDs light briefly but the system unit still fails to
initialize, see Section 3.8, “Initializing Motherboard POST” on page 3-23.

4.2 Video Output Failure

This section provides video output failure symptom and suggested action.

Symptom

No video at the system monitor.

Action

Check the monitor AC power cord. Ensure that the AC power cord is connected to
the monitor and to the wall receptacle. Verify that the wall receptacle is supplying
AC power to the monitor. Check the video cable connection between the monitor
and the system graphics card output port at the rear of the system. Check that the
CPU module is properly seated. If the AC connection to the monitor is correct, the
video cable is correctly connected, and the CPU module is properly seated, the
system monitor or the system graphics card may be defective. Replace the monitor
or the graphics card.

4.3 Disk Drive or CD-ROM Drive Failure

This section provides hard drive and CD-ROM drive failure symptoms and
suggested actions.

Chapter 4 Troubleshooting Procedures 4-3

Symptom

A hard drive read, write, or parity error is reported by the operating system or
customer application.

A CD-ROM drive read error or parity error is reported by the operating system or
customer application.

Action

Replace the drive indicated by the failure message. The operating system identifies
the internal drives as listed in

TABLE4-1 Internal Drives Identification

Operating System Address Drive Physical Location and Target

c0t0d0s# Lower hard drive, target 0
c0t1d0s# Upper hard drive, target 1
c0t6d0s# CD-ROM drive, target 6 (optional)
c0t5d0s# Tape drive, target 5 (optional)

Note – The # symbol in the operating system address examples may be a numeral

between 0 and 7 that describes the slice or partition on the drive.

TABLE 4-1.

Symptom

Hard drive or CD-ROM drive fails to respond to commands.

Note – To bypass POST, type: setenv diag-switch? false at the ok prompt.

Action

Test the drive response to the probe-scsi command as follows:

1. At the system ok prompt:
a. Type reset-all.
b. Type probe-scsi.

4-4 Sun Ultra 60 Service Manual • August 2001

If the hard drive responds correctly to probe-scsi, the message identified in

CODE EXAMPLE 4-4 is displayed. If the drives respond and a message is displayed, the

system SCSI controller has successfully probed the devices. This is an indication that
the motherboard is operating correctly. If one drive does not respond to the SCSI
controller probe but the other does, replace the unresponsive drive. If one hard drive
is configured with the system and the probe-scsi test fails to show the device in
the message, replace the drive. If the problem is still evident after replacing the hard
drive, replace the SCSI drive bay (see Section 8.3, “Hard Drive Bay With SCSI
Assembly” on page 8-7) If replacing both the hard drive and the SCSI drive bay does
not correct the problem, replace the motherboard.
