precautions to prevent damage. To prevent electrostatic damage observe the
following precautions:

o Transport products in static-safe containers such as conductive tubes,

bags, or boxes.

o Keep electrostatic-sensitive parts in their containers until they arrive

at static-free stations.

o Cover work stations with approved static-dissipating material. Provide a

wrist strap connected to the work surface and properly grounded tools and
equipment.

o Keep work area free of non-conductive materials such as ordinary plastic

assembly aids and styrofoam.

DIAGNOSTICS (DIAGS)

Diagnostic error codes occur if the system recognizes a problem while
running the Diagnostics program. These error codes help identify possible
defective subassemblies.

Tables 3-2 through 3-17 list possible error codes, a description of the
error condition, and the action required to resolve the error condition.

In each case, the Recommended Action column lists the steps necessary to
correct the problem. After completing each step, run the Diagnostics
program to verify whether the error condition has been corrected. If the
error code reappears, perform the next step, then run the Diagnostics
program again. Follow this procedure until the Diagnostics program no
longer detects an error condition.

For assistance in the removal and replacement of a particular subassembly,
see Chapter 2, "Removal and Replacement Procedures."

If you encounter an error condition, complete the following steps before
starting problem isolation procedures:

1. Ensure that there is proper ventilation. The computer should have
approximately 3 inches (7 to 8 cm) clearance at the front and back of
the system unit.

2. Turn off the computer and peripheral devices.

3. Disconnect any peripheral devices other than the monitor and keyboard.
Do not disconnect the printer if you want to test it or use it to log
error messages.

4. Delete the power-on password, if set. You will know that the power-on
password is set when a key icon appears on the screen when POST
completes. If this occurs, you must enter the password to continue.
To delete the password, type the current password and press the Enter
key.

5. If you do not have access to the password, you must disable the
power-on password by using the Password Disable switch on the system
board.

6. Install an Ethernet loopback plug when instructed to by Diagnostics
utility. (part no. 142054-001)

7. Run the latest version of Diagnostics.

DRIVE ARRAY - ADVANCED DIAGNOSTICS (DAAD)

Drive Array - Advanced Diagnostics (DAAD) is a DOS-based tool designed to
run on all COMPAQ products that contain a COMPAQ Intelligent Drive Array
Controller (IDA), COMPAQ Intelligent Drive Array Controller-2 (IDA-2), or
COMPAQ 32-Bit IDA Expansion Controller. The two main functions of DAAD are
to collect all possible information about the array controllers in the
system and to offer a list of all detected problems.

NOTE: Refer to the Drive Array - Advanced Diagnostics User Guide for

complete details and procedures about this diagnostic tool.

DAAD works by issuing multiple commands to the array controllers to
determine if a problem exists. This data can then be saved to a file
and, for severe situations, this file can be sent to Compaq for analysis.
In most cases, DAAD will provide enough information to initiate problem
resolution immediately.

NOTE: DAAD does not write to the drives or destroy data. It does not

change or remove configuration information.

Starting DAAD

To start DAAD:

1. Insert the DAAD diskette into drive A and reboot the system. If you are
at the DOS prompt, enter the following:

A:DAAD

2. A dialog box displays indicating the version of DAAD installed. Press
the Enter key to continue.

To exit without continuing, press the Esc key.

3. If you continue, a "Please Wait" panel will display indicating that
DAAD is identifying the system parameters.

DAAD gathers all the information it can from all of the array
controllers in the system. The time it takes to gather this information
depends on the size of your system.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Do not cycle the power because the utility must perform low-level
operations that, if interrupted, could cause the controller to revert back
to a previous level of firmware if the firmware was soft-upgraded.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

4. Another "Please Wait" panel will appear to indicate that the utility is
identifying the ROM version. When this completes, the main DAAD screen
will display.

NOTE: To generate a DAAD report without starting the interactive portion of

the utility, enter the following at the DOS prompt: DAAD filename
where filename is the name of the file or report.

Refer to Chapter 3 of the Drive Array - Advanced Diagnostics User Guide for
descriptions of the DAAD screens.

DAAD Diagnostic Messages

The following is a description of the diagnostic messages that may appear
in the dialog box of the Diagnosis menu. Included with each message is a
probable cause and a probable solution or troubleshooting routine.

To view the problems detected by DAAD, select the Diagnosis button. If DAAD
found no problems, a message, "No Problems Detected," will display.

---------------------------------------------------------------------------

Accelerator board not detected

The IDA-2 board did not detect the presence of a configured array
accelerator board.

Install an array accelerator board onto the IDA-2 controller. If you have
an array accelerator board installed, check the seating to ensure that it
has been properly installed onto the IDA-2 board. You may need to run the
COMPAQ EISA Configuration Utility and disable the array accelerator board
to get this message off the screen.

---------------------------------------------------------------------------

Accelerator error log

This is a list of the last 32 parity errors on transfers between the IDA-2
board transfer buffer and memory on the array accelerator board. The
starting memory address, transfer count, and operation (read and write)
displays.

If there are a number of these parity errors, you may need to replace the
array accelerator board.

---------------------------------------------------------------------------

Accelerator parity read errors: n

This message displays the number of times that read memory parity errors
were detected during transfers between the IDA-2 board transfer buffer and
memory on the array accelerator board.

If there are a number of these parity errors, you may need to replace the
array accelerator board.

---------------------------------------------------------------------------

Accelerator parity write errors: n

This message displays the number of times that write memory parity errors
were detected during transfers between the IDA-2 board transfer buffer and
memory on the array accelerator board.

If there are a number of these parity errors, you may need to replace the
array accelerator board.

---------------------------------------------------------------------------

Accelerator status: Permanently disabled

The array accelerator board has been permanently disabled. It will remain
disabled until it is reinitialized using the EISA Configuration Utility.

Check the Disable Code field. Run the EISA Configuration Utility to
reinitialize the array accelerator board.

---------------------------------------------------------------------------

Accelerator status: Possible data loss in cache

Possible data loss in cache was detected during power-up due to all of the
batteries being below the sufficient voltage level and no presence of the
identification signatures on the array accelerator board.

There is no way to determine if dirty or bad data was in the cache and is
now lost.

---------------------------------------------------------------------------

Accelerator status: Temporarily disabled

The array accelerator board has been temporarily disabled.

Check the Disable Code field.

---------------------------------------------------------------------------

Accelerator status: Unrecognized status

A status returned from the array accelerator board that DAAD does not
recognize.

Call your Authorized COMPAQ Reseller for the latest copy of DAAD.

---------------------------------------------------------------------------

Accelerator status: Valid data found at reset

Valid data was found in the posted write memory at re-initialization. The
data will be flushed to disk.

This is NOT an error or data loss condition. No action needs to be taken.

---------------------------------------------------------------------------

Accelerator status: Warranty alert

A catastrophic problem has occurred with the array accelerator board. Refer
to the other messages on the Diagnosis screen for the exact meaning of this
message.

Replace the array accelerator board.

---------------------------------------------------------------------------

Battery pack X below reference voltage

The indicated battery pack is below the required voltage levels.

Allow for sufficient time for the batteries to recharge (36 hours). If the
batteries have not recharged after 36 hours, replace the battery pack.

---------------------------------------------------------------------------

Battery X not fully charged

The battery is not fully charged.

If 75% of the batteries present are fully charged, the array accelerator is
fully operational. If more than 75% of the batteries are not fully charged,
allow 36 hours to recharge them.

---------------------------------------------------------------------------

Board not attached

The IDA-2 board has been configured for use with an array accelerator
board, but one is currently not attached.

Locate the original array accelerator board and attach it to the IDA-2
board.

---------------------------------------------------------------------------

CMOS present, controller not detected

EISA nonvolatile RAM has a configuration for an array controller but there
is no board in this slot. Either a board has been removed from the system
or a board has been placed in the wrong slot.

Place the array controller in the proper slot or run the EISA Configuration
Utility to reconfigure nonvolatile RAM to reflect the removal or new
position.

---------------------------------------------------------------------------

Compatibility port problem detected

You have the compatibility port configured for this IDA controller. When
DAAD was verifying this interface, a serious problem was detected.

A hardware problem has occurred and you should replace the IDA controller.

---------------------------------------------------------------------------

Configuration signature is zero

DAAD detected that nonvolatile RAM contains a configuration signature that
is zero. Old versions of the EISA Configuration Utility could cause this.

Run the latest version of EISA Configuration Utility to configure the
controller and nonvolatile RAM.

---------------------------------------------------------------------------

Configuration signature mismatch

The array accelerator board has been configured for a different IDA-2
board. The configuration signature on the array accelerator board does not
match the one stored on the IDA-2 board.

To recognize the array accelerator board, run the EISA Configuration
Utility.

---------------------------------------------------------------------------

Controller communication failure occurred

If problems exist with this drive, replace it with a COMPAQ drive.

---------------------------------------------------------------------------

Identify controller data did not match with CMOS

The identify controller data from the array controller did not match with
the information stored in nonvolatile RAM. This could occur if new,
previously configured drives have been placed in a system that has also
been previously configured. It could also occur if the firmware on the
controller has been upgraded and the EISA Configuration Utility was not
run.

Check the identify controller data under the INSPECT utility. If the
firmware version field is the only thing different between the controller
and nonvolatile RAM data, this is not a problem. Otherwise run the EISA
Configuration Utility.

---------------------------------------------------------------------------

Identify logical drive data did not match with CMOS

The identify unit data from the array controller did not match with the
information stored in nonvolatile RAM. This could occur if new, previously
configured drives have been placed in a system that has also been
previously configured.

Run the EISA Configuration Utility to configure the controller and
nonvolatile RAM.

---------------------------------------------------------------------------

Insufficient adapter resources

The adapter does not have sufficient resources to perform operations to the
array accelerator board. Drive rebuild may be occurring.

Operate the system without the array accelerator board until the drive
rebuild completes.

---------------------------------------------------------------------------

Less than 75% batteries at sufficient voltage

The operation of the array accelerator board has been disabled due to less
than 75% of the battery packs being at the sufficient voltage level.

Allow sufficient time for the batteries to recharge (36 hours). If the
batteries have not recharged after 36 hours, replace the array accelerator
board.

---------------------------------------------------------------------------

Logical drive X failed due to cache error

This logical drive failed due to a catastrophic cache error.

Replace the array accelerator board and reconfigure using the EISA

Configuration Utility.

---------------------------------------------------------------------------

configured for No Fault Tolerance and one or more drives fail, this status
will occur. If mirroring is enabled, and any two mirrored drives fail, this
status will occur. If Data Guarding is enabled, and two or more drives fail
in this unit, this status will occur. This status may also occur if another
configured logical drive is in the WRONG DRIVE REPLACED or LOOSE CABLE
DETECTED state.

Check for drive failures, wrong drive replaced, or loose cable messages. If
there was a drive failure, replace the failed drive(s) and then restore the
data for this logical drive from the tape backup. Otherwise, follow the
wrong drive replaced or loose cable detected procedures.

---------------------------------------------------------------------------

RAPID RECOVERY SERVICES

The COMPAQ ProSignia provides rapid recovery services for diagnosing and
recovering from errors. These tools are available for local and remote
diagnosis and recovery. The following topics are discussed here:

o Automatic Server Recovery (ASR)

o Server Health Logs

o EISA Configuration History Files

NOTE: Please refer to the COMPAQ ProSignia User's Reference Guide for

complete details and procedures about this diagnostic tool.

Automatic Server Recovery

The Automatic Server Recovery (ASR) feature can be optionally enabled to
restart a PC Server after a critical hardware or software error has
occurred. If a critical error occurs, the PC Server will record the error
information in the Server Health Logs, reboot the system, and page you. You
can choose to configure the system for either automatic recovery or for
attended local or remote access to diagnostic and configuration tools.

NOTE: ASR is only available on operating systems using the ASR drivers

provided by Compaq.

The following graphic explains how ASR works:

Configuring the PC Server for Automatic Server
Recovery (ASR)

When setting up the server to use Automatic Server Recovery (ASR), you must
set the ASR Timer, select the pager number to call, and specify how you
want the PC Server to recover from critical system faults. This selection
process is accomplished through the COMPAQ EISA Configuration Utility.

The ASR depends on an operating system driver that routinely notifies the
ASR hardware that the system is operating properly. You should set the ASR
Timer to allow the ASR to wait a prudent period of time before resetting
the system and activating the recovery process after a fault occurs. If the
time between ASR notifications by the driver exceeds the specified time
period, it will assume a fault has occurred and initiate the recovery
process.

For example, if the ASR Timer is set to 10 minutes, the system will not
reset the PC Server unless 10 minutes elapses with no notification from the
driver that the system is operating properly.

You can select to be paged (modem required) and what mode the PC Server
will be in when it restarts after a critical error. The following sections
describe the different reboot options and the system requirements for each
level.

Unattended Recovery

For unattended recovery, ASR will log the error information to the Critical
Error Log, reset the server, test all memory, automatically deallocate any
bad memory blocks found, page you (if modem is present and paging is
selected), and attempt to reboot the operating system. Often the PC Server
will restart successfully, making this the ideal choice for remote
locations where trained service personnel are not immediately available.

The ASR will only attempt the recovery process a limited number of times.
If the PC Server continues to experience hardware/software errors and the
number of recovery cycles exceed the retry limit, the PC Server will log an

error to the Critical Error Log and continue to boot the COMPAQ Utilities
from the hard drive.

The requirements to use this level of the ASR feature are:

o Operating system with ASR support

o ASR configured to load the operating system after reboot

o Optional Hayes compatible modem (only required for paging)

Attended Recovery

For local or remote installations where it is desirable to have you
supervise the recovery, ASR will log the error information to the Critical
Error Log, reset the PC Server, test all memory, automatically deallocate
any bad memory blocks found, page you, boot the COMPAQ Utilities from the
hard drive, and place the modem in auto answer mode. These utilities are
placed on a special system utilities partition on the hard drive during the
system configuration process. If a modem with an auto-answer feature is
installed, you can dial in and remotely diagnose or reconfigure the PC
Server; otherwise, this can be done from the PC Server console. The
requirements to use this level of the ASR feature are:

o Operating System with ASR support

o EISA Configuration Utility and Diagnostics Utility installed on the

system partition of the hard drive

o ASR configured to load the COMPAQ Utilities after reboot

o Optional Hayes compatible modem with auto-answer feature (only required

for remote operations and paging)

For remote operations, the administrator must have access to a
communications software package capable of terminal emulation to a local
terminal with VT100 or ANSI terminal capabilities.

NOTE: If the remote site is using something other than these two packages,

it is still possible to configure remotely as long as the package
contains either an ANSI terminal or VT100 terminal emulator set for
8 data bits, 1 stop bit, and no parity. However, additional setup
not outlined in this document may be required, and functionality may
be reduced.

ASR Security

The standard COMPAQ ProSignia security password features function
differently during Automatic Server Recovery than during a typical system
startup.

During ASR the PC Server will not prompt for the Power-On Password. This
allows the ASR to restart the Operating System or COMPAQ utilities without
user intervention.

To maintain system security, the PC Server should be set to boot in Network
Server Mode (an option in the EISA Configuration Utility). This option
ensures that the PC Server keyboard is locked until you enter the Keyboard
Password.

You should also select an Administrator Password (an option in the EISA
Configuration Utility). During attended ASR (local or remote), you must
enter this Administrator Password before any modifications can be made to
the PC Server configuration.

Server Health Logs

The Server Health Logs contain information to help identify and correct any
PC Server failures and correlate hardware changes with PC Server failure.
The Server Health Logs are stored in nonvolatile RAM and consist of the
Critical Error Log and the Revision History Table.

In the event that errors occur, information about the errors are
automatically stored in the Critical Error Log.

Whenever boards or components (that support revision tracking) are updated
to a new revision, the Revision History Table will be updated.

Critical Error Log

The Critical Error Log records noncorrectable memory errors as well as
catastrophic hardware and software errors that typically cause the system
to fail. This information helps you quickly identify and correct the
problem, minimizing downtime.

The log can be viewed through Inspect Utility, Diagnostics Utility, or the
optional INSIGHT Manager and Server Manager/R. The Diagnostics Utility
either resolves the error or suggests corrective action.

The Critical Error Log identifies and records all the following errors.
Each error type is briefly explained below. When any of these errors are
encountered, you should run the Diagnostics Utility.

===========================================================================

Revision History Table

Some errors can be resolved by reviewing changes to the COMPAQ ProSignia
configuration. The PC Server has an Automatic Revision Tracking (ART)
feature that helps you review recent changes to the PC Server's
configuration.

One ART feature is the Revision History Table which contains the hardware
version number of the system board and any other EISA boards providing
ART-compatible revision information. The Revision History Table is stored
in nonvolatile RAM and is accessed through Diagnostics, Inspect, the
optional COMPAQ Server Manager/R, and the optional COMPAQ INSIGHT Manager.

The Revision History Table feature allows precise identification of the
components in a PC Server. The table is updated when the system ROM detects
a board version change in an EISA expansion slot. The table also contains
complete version information on the previous configuration. This feature
allows correlation of hardware changes with PC Server failure. The
following information is stored in the Revision History Table:

o Type of board (System or EISA)
o Slot number
o EISA ID

o Version

EISA Configuration History Files

The EISA Configuration History Files are a part of the ART feature that
allow you to review modifications to the system configuration.

If a change has been made to the configuration file, the EISA Configuration
Utility will keep a history of the system configuration file. The EISA
Configuration Utility stores the three most recent configurations.

The most recent configuration of the EISA Configuration History Log can be
displayed and printed using the INSPECT utility. All three versions can be
printed for historical purposes or reinstalled through the Maintain
Configuration Utility feature of the EISA Configuration Utility.

ROMPaq

The use of flash ROMs in the COMPAQ ProLinea allows the firmware (BIOS) to
be upgraded with the software utility ROMPaq. To upgrade the ROM, insert
the ROMPaq diskette into drive A and cold boot the system. The ROMPaq
utility will then check the system and provide a choice (if more than one
exists) of ROM revisions that the system can be upgraded to.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Do not turn the power off during a firmware upgrade. A loss of power
during upgrade may corrupt the upgrade.
