Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To prevent
electrostatic damage, observe the following precautions:
■
Transport products in static-safe containers such as conductive tubes, bags, or boxes.
■
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
■
Cover work stations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
■
Keep work area free of nonconductive materials such as ordinary plastic assembly aids
and foam packing.
■
Make sure you are always properly grounded when touching a static-sensitive component
or assembly.
■
Avoid touching pins, leads, or circuitry.
■
Always place drives PCB assembly-side down.
■
Use conductive field service tools.
Symbols in Equipment
WARNING: Any surface or area of the equipment marked with these symbols
indicates the presence of a hot surface or hot component. If this surface is
contacted, the potential for injury exists. To reduce the risk of injury from a hot
component, allow the surface to cool before touching it.
WARNING: Any surface or area of the equipment marked with these symbols
indicates the presence of electric shock hazards. The enclosed area contains no
operator serviceable parts. To reduce the risk of injury from electric shock
hazards, do not open this enclosure.
WARNING: Any RJ-45 receptacle marked with these symbols indicates a Network
Interface Connection. To reduce the risk of electric shock, fire, or damage to the
equipment, do not plug telephone or telecommunications connectors into this
receptacle.
CLASS 1 LASER PRODUCT
WARNING: This label or equivalent is located on the surface of your CD-ROM
drive. This label indicates that the product is classified as a CLASS 1 LASER
PRODUCT.

Removal and Replacement Procedures
Any product or assembly marked with these symbols indicates that the
component exceeds the recommended weight for one individual to handle
safely.
Weight in kg
Weight in lb
Preparation Procedures
Before beginning to remove any serviceable parts, determine whether the part is hot-pluggable
or non-hot-pluggable.
Hot-Pluggable Devices
Hot-pluggable devices in the ProLiant ML370 Servers include SCSI hard drives and power
supplies (with redundant power supply option kit).
IMPORTANT: It is not necessary to turn off the server to replace hot-plug devices when they are not in
active use.
Non-Hot-Pluggable Devices
If the part is non-hot-pluggable, the server must be powered down. Non-hot-pluggable parts
include the processors, all boards, DIMMs, fans, drive cages, and the standard power supply.
Powering Down the Server
System power in ProLiant ML370 Servers does not completely shut off with the front panel
Power On/Standby switch. The switch toggles between On and Standby, rather than On and Off.
The standby position removes power from most electronics and the drives, but portions of the
hot-plug power supply and some internal circuitry remain active. To completely remove all
power from the system, you must disconnect all power cords from the server.
WARNING: To reduce the risk of injury from electric shock, remove all power
cords to completely disconnect power from the system.
WARNING: To reduce the risk of personal injury or damage to the equipment, ensure that only
one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING: Because the rack allows you to stack computer components on a vertical rather
than horizontal plane, you must take precautions to provide for rack stability and safety. It is
important that you follow these precautions to provide for rack stability and safety and to
protect both personnel and property. Heed all cautions and warnings throughout the installation
instructions that came with the server.
2-3
2-4
Compaq ProLiant ML370 Maintenance and Service Guide
WARNING: To reduce the risk of personal injury or damage to the equipment: If the server is
mounted in a rack, internal devices may not be accessible for removal and replacement. If the
server must be removed from the rack for device accessibility, remove the server from the rack
and place it on a sturdy table or workbench. Refer to the ProLiant ML370 Servers Setup and
Installation Guide for further information on working with racks.
CAUTION: The system power in the server does not completely shut off from the front Power
On/Standby switch. Moving the switch from On to Standby leaves some portions of the hot-plug
power supply and some internal circuitry active. Disconnect all power cords from the server to
remove all power from the system.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure. For more information, see the
section titled “Electrostatic Discharge Information” earlier in this chapter.
To power down the server:
1. Press the Power On/Standby switch to Standby. This places the server in standby mode,
thereby disabling the main power supply output and providing auxiliary power to the
server. Standby does not completely remove power from the system.
2. Verify that the system power LED indicator on the front panel, near the Power
On/Standby switch, is amber and that the fan noise stops.
3. Disconnect all AC power cords from the AC outlet, then from the server.
4. Disconnect all external peripheral devices from the server.
5. For stability and safety, properly positioning the server is critical. If the server is mounted
in a rack, remove the rack model server from the rack and place it on a sturdy table or
workbench. Refer to the ProLiant ML370 Servers Setup and Installation Guide for
instructions.
Rack Warnings
WARNING: To reduce the risk of personal injury, make sure that the rack is adequately
stabilized before extending a component outside the rack. A rack may become unstable if more
than one component is extended for any reason. Extend only one component at a time.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
■
The leveling jacks are extended to the floor.
■
The full weight of the rack rests on the leveling jacks.
■
The stabilizers are attached to the rack if it is a single rack installation.
■
The racks are coupled together in multiple rack installations.
Removal and Replacement Procedures
Server Warnings and Precautions
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
WARNING: To reduce the risk of electric shock or damage to the equipment:
■
Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
■
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
■
Install the power supply before connecting the power cord to the power supply.
■
Unplug the power cord before removing the power supply from the server.
■
Disconnect power from the server by unplugging the power cord from either the electrical
outlet or the server. If the system has multiple power supplies, disconnect power from the
system by unplugging all power cords from the power supplies.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation during a power
failure.
CAUTION: ProLiant ML370 Servers must always be operated with the system unit cover on.
Proper cooling will not be achieved if the system unit cover is removed.

Compaq ProLiant ML370 Maintenance and Service Guide
Default Configuration
When the system is first powered up, the system ROM detects the unconfigured state of the
hardware and provides default configuration settings for most devices. By providing this
initialization, the system can run Diagnostics and other software applications before running the
normal SmartStart and System Configuration programs.
Default Configuration Messages
IMPORTANT: If you chose to format and partition the boot drive before running SmartStart and the
System Configuration programs, this may prohibit creating a Compaq System Partition and the off-line
remote management features that it provides.
If you insert a System Configuration, Diagnostics, or SmartStart and Support Software CD into
the CD-ROM drive prior to powering up the server, the system ROM boots to that utility. If the
system ROM does not detect one of those CDs, you will be prompted for the intended operating
system. The system reboots if any operating system-dependent configurations have changed
with the new operating system selection. If the selected operating system-dependent
configurations are the same as the current configurations, the system boots normally. If you
enter a wrong choice, on subsequent re-boots you may change the operating system.
Inspect Utility
The Inspect Utility provides configuration information such as the contents of the operating
system startup files, the current memory configuration, the ROM version, and Server Health
Log information. It operates with MS-DOS and in the MS-DOS emulation mode of OS/2.
Running the Inspect Utility
1. Turn the server off, and back on. Then press F10 when the cursor appears in the upper

POST Error Messages
If POST finds an error in the system, an error condition is indicated by an audible and/or visual
message. If an error code displays on the screen during POST or after resetting the system, use
the instructions in the POST Error Messages table. The error messages and codes listed include
all codes generated by Compaq products. The system generates only those codes that are
applicable to the configuration and options.
NOTE: Many of the actions listed require you to run Diagnostics or the Compaq System Configuration
Utility. Steps for running these utilities are provided following the POST Error Messages tables.
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 Diagnostics no longer detects an error condition.

Test Error Codes Tables include all test error codes generated by Compaq Server Diagnostics.
Each code has a corresponding description and recommended action(s).
When you select Diagnostics and Utilities from the System Configuration Utility main menu,
the utility prompts you to test, inspect, upgrade, and diagnose the server.
Diagnostics and Utilities are located on the Compaq system partition on the hard drive and must
be accessed when a system configuration error is detected during the Power-On Self-Test
(POST). Compaq Diagnostics software is also available on the Compaq SmartStart and Support
Software CD. You can create a Diagnostics diskette from the SmartStart and Support
Software CD and run Diagnostics from diskette. See procedure in the “Running Compaq
Utilities” section earlier in this chapter.
The following options are available from the Diagnostics and Utilities menu:
■
Test Computer
■
Inspect Computer
■
Upgrade Firmware
■
Remote Utilities
■
Diagnose Drive Array
Diagnostic error codes are generated when the Diagnostics software recognizes a problem.
These error codes help identify possible defective subassemblies.
Steps for Diagnostics
In each case, the Recommended Action column lists the steps necessary to correct the problem.
After completing each step, run the Diagnostics Utility to verify that the error condition has
been corrected. If the error code reappears:
1. Perform the next step listed in the table.
2. Run the Diagnostics program again.
3. Follow this procedure until the Diagnostics program no longer detects an error condition.

Diagnostics and Troubleshooting
Array Diagnostic Utility (ADU)
Array Diagnostic Utility (ADU) is a Windows-based software tool designed to run on all
Compaq servers that support Compaq array controllers, and are running SmartStart 4.10 or later.
The two main functions of ADU are to collect all possible information about array controllers in
the system and to generate a list of detected problems. The error messages and codes listed
include all codes generated by Compaq products. The system generates only codes applicable to
the configuration and options in the server.
ADU works by issuing multiple commands to the array controllers to determine if a problem
exists. This data can then be saved to a file. In severe situations, this file can be sent to Compaq
for analysis. In most cases, ADU provides enough information to initiate problem resolution
immediately.
NOTE: ADU does not write to the drives, destroy data, or change or remove configuration information.
Starting ADU
1. Insert the SmartStart CD into the CD-ROM drive.
2. Reboot the system from the SmartStart CD.
3. Select Array Diagnostic Utility (ADU) from the System Utilities menu.
A “Please Wait” panel displays, indicating that ADU is identifying the system parameters.
ADU gathers information from all of the array controllers in the system. The time it takes to
gather this information depends on the size of the system. When the information gathering
process is complete, ADU displays the main screen or a panel indicating any problems
detected.
CAUTION: Do not cycle the power during this process. ADU must perform low-level operations
that, if interrupted, could cause the controller to revert to a previous level of firmware if the
firmware was soft-upgraded.
4. To generate an ADU report, select File then Save Data from the command menu.

Integrated Management Log
On servers supporting the Integrated Management Display, the Compaq Integrated Management
Log (IML) replaces the Critical Error Log and Correctable Memory Logs. IML records system
events and stores them in an easily viewable form. Each event is marked with a time-stamp with
one-minute granularity.
Events listed in the Integrated Management Log are categorized as one of four event severity
levels:
■
Statusindicates that the message is informational only.
■
Repairedindicates that corrective action has been taken.
■
Cautionindicates a nonfatal error condition.
■
Criticalindicates a component failure.
The Integrated Management Log requires Compaq operating system-dependent drivers. Refer to
the Compaq Support Software CD for instructions on installing the appropriate drivers.
Refer to the setup and installation guide that came with the server or the Integrated Management
Display User Guide provided with the Integrated Management Display option kit.
Multiple Ways of Viewing the Log
You can view an event in the IML in several ways:
■
On the Integrated Management Display
■
From within Compaq Insight Manager
■
From within the Compaq Survey Utility
■
From within the IML Management Utility
Integrated Management Display
The Integrated Management Display is an LCD panel that presents information directly at the
server, assisting in diagnosing and servicing the server without a keyboard and monitor.
Compaq Insight Manager
Compaq Insight Manager is a comprehensive management tool to monitor and control the
operation of Compaq servers and clients. Compaq Insight Manager consists of two components:
a Windows-based console application, and server- or client-based management data collection
agents. Starting with Compaq Insight Manager 4.0, the agents for Windows NT and NetWare
are also Web-enhanced; that is, these agents enable Web browser access and monitoring of
management information.
The management agents monitor over 1,000 management parameters. Key subsystems are
instrumented to make health, configuration, and performance data available to agent software.
Agents act upon data by initiating information, such as network interface or storage subsystem
performance statistics.
Diagnostics and Troubleshooting
Viewing the Event List

Compaq Survey Utility
The Compaq Survey Utility is a serviceability tool available from Windows NT and Novell
NetWare. It delivers online-configuration capture and comparison to maximize server
availability. It is delivered on the Compaq Management CD in the SmartStart package or is
available on the Compaq website. Refer to the Compaq Management CD for information on
installing and running the Compaq Survey Utility.
After running the Compaq Survey Utility, view the IML by loading the output of the utility
(typically called “survey.txt”) into a text viewer such as Microsoft Notepad. The event list
follows the system slot information. After opening the text file, print it using the print feature of
the viewer.
Compaq IML Management Utility
The Compaq IML Management Utility is a DOS-based tool that gives you the offline ability to
review, mark corrected, and print events from the IML. It is located on the Compaq SmartStart

Rapid Error Recovery
Compaq servers provide rapid recovery services for diagnosing and recovering from errors.
These tools are available for local and remote diagnosis and recovery.
Rapid recovery means fast identification and resolution of complex faults. The Rapid Recovery
Engine and Insight Management Agents notify the system administrator when a failure occurs,
ensuring that the server experiences minimal downtime. You enable these features through the
System Configuration Utility. These integrated server management features are:
■
Automatic Server Recovery-2 (ASR-2)
■
Integrated Management Logs
■
Storage Fault Recovery Tracking
■
Storage Automatic Reconstruction (requires Compaq Smart Array Controller or Compaq
Integrated Smart Array Controller)
■
Network Interface Fault Recovery Tracking
■
Memory Fault Recovery Tracking
These are discussed in more detail on the server documentation CD.
Automatic Server Recovery-2
Automatic Server Recovery-2 (ASR-2) lets the server restart automatically from the operating
system or the Compaq Utilities. To use this feature, you must use the System Configuration
Utility to install Compaq Utilities in the Compaq system partition.
You can enable the ASR-2 feature to restart a server after a critical hardware or software error
occurs. If a critical error occurs, the server records the error information in the Integrated
Management Log, restarts the system, and pages you. Using the Compaq System Configuration
Utility, configure the system for automatic recovery or for attended local or remote access to
diagnostic and configuration tools.
NOTE: ASR-2 is available only on specific operating systems. ASR-2 drivers are provided by Compaq.
You can also configure ASR-2 to page an administrator when the system restarts. ASR-2
depends on the application and driver that routinely notify the ASR-2 hardware of proper
system operations. If the time between ASR-2 notifications exceeds the specified period,
ASR-2 assumes a fault has occurred and initiates the recovery process.
To configure ASR-2:
1. Run the System Configuration Utility.
2. Select View and Edit Details.
3. Set the software error recovery status to Enabled.
4. Set the software error recovery timeout.
Diagnostics and Troubleshooting
The available recovery features are:
■
Software Error Recoveryautomatically restarts the server after a software-induced
server failure
■
Environmental Recoveryallows the server to restart when temperature, fan, or AC
power conditions return to normal
Unattended Recovery
For unattended recovery, ASR-2 performs the following actions:
■
Logs the error information to the IML
■
Resets the server
■
Pages you (if a modem is present and you selected Paging)
■
Tries to restart the operating system
Often the server restarts successfully, making unattended recovery the ideal choice for remote
locations where trained service personnel are not immediately available.
If ASR-2 cannot restart the server within 10 attempts, it places a critical error in the Integrated
Management Log, starts the server into Compaq Utilities, and enables remote access (if you
configured remote access).
To use this level of ASR-2, you must configure ASR-2 to load the operating system after restart.
Attended Recovery
For attended recovery, ASR-2 performs the following actions:
■
Logs the error information to the IML
■
Resets the server
■
Pages you (if a modem is present and you selected Paging)
■
Starts Compaq Utilities from the hard drive
■
Enables remote access
During system configuration, these utilities are placed on the system utilities partition of the
hard drive.
If you have configured for dial-in access and have a modem with an auto-answer feature
installed, you can dial in and remotely diagnose or reconfigure the server.
If you have configured the Compaq Utilities for network access, you can access the utilities over
the network. You can use Compaq Insight Manager for dial-in or network access.

Compaq ProLiant ML370 Maintenance and Service Guide
Hardware Requirements
To use this level of ASR-2 over a modem, you need the following:
■
A Compaq external Netelligent modem or compatible
■
System Configuration Utility and Diagnostics Utility installed on the Compaq system
partition of the hard drive
■
ASR-2 configured to load Compaq Utilities after restart
You can also run Compaq Utilities remotely over an IPX or IP network using the Network
feature:
■
To use Compaq Utilities on an IPX network, you must have Compaq Insight
Manager 2.0 or later or an NVT (Novell Virtual Terminal) Terminal Emulator with
VT100 or ANSI terminal capabilities.
■
To use Compaq Utilities on an IP network, you must have Compaq Insight Manager 2.10
or later, or a Telnet Terminal Emulator with VT100 or ANSI capabilities.
If you are notified that ASR-2 restarted the server and you have restarted to Compaq Utilities,
use the Inspect Utility or Compaq Insight Manager to view the critical error in the Compaq
system partition. Run Diagnostics to diagnose and resolve the problem.
You can configure ASR-2 to restart the server into Compaq Utilities to diagnose the critical
error or to start the operating system to return the server to operational status as rapidly as
possible.
When you enable ASR-2 to start the operating system, the server tries to start from the primary
partition. In this mode, ASR-2 can page you if a critical error occurs, but you cannot access
Compaq Utilities.
When you enable ASR-2 to start Compaq Utilities, the server restarts after a critical error and
loads Compaq Utilities from the Compaq system partition on the hard drive.
Diagnostics and Troubleshooting
You can configure the server to start Compaq Utilities in four different ways:
■
Without remote console support; for example, to run Compaq Utilities from the server
console only
■
With remote console support using modems for dial-in access
■
With remote console support using a modem to dial a predetermined telephone number
■
With remote console support through a network connection (IP or IPX)

Compaq Integrated Remote Console
The standard Compaq Integrated Remote Console performs a wide range of configuration
activities. Console features include:
■
Is accessible using ANSI terminal
■
Operates independently of the operating system
■
Provides for remote server reboot
■
Provides access to system configuration
■
Uses out-of-band communication with dedicated management modem installed in the
server
For more information, see the Integrated Remote Console User Guide that shipped with the
server.
IMPORTANT: Before configuring ASR-2, verify that the System Configuration Utility and Diagnostics
software are installed on the Compaq system partition. ASR-2 must have this to start Compaq Utilities
after a system restart. Compaq recommends this even if you configure ASR-2 to start the operating
system.
Compaq Health Driver
The Compaq Health Driver continually resets the ASR-2 timer according to the frequency you
specified in the System Configuration Utility (for example, 10 minutes). If the ASR-2 timer
counts down to zero before being reset, due to an operating system crash or a server lockup,
ASR-2 restarts the server into either Compaq Utilities or the operating system (as indicated by
the System Configuration parameters). The default value is 10 minutes. The allowable settings
are 5, 10, 20, and 30 minutes.
For remote and off-site (unattended) servers, setting the software error recovery time-out
for 5 minutes reduces server downtime and allows the server to recover quickly. For local
(attended) servers located onsite, you can set the software error recovery timeout for
20 or 30 minutes, giving you time to arrive at the server if you wish to manually diagnose the
problem.
The Compaq Health Driver is independent of the ASR-2 timer. You should load it and enable
the ASR-2 timer. This allows the driver to detect and log information about numerous hardware
and software errors in the IML. However, you cannot enable the ASR-2 timer without loading
the Compaq Health Driver.
Before ASR-2 restarts the server, it records any information available about the condition of the
operating system in the Compaq system partition, or the IML depending on the server support.
This information can be used to diagnose an operating system crash or server lockup, while still
allowing the server to be restarted.

Booting into Compaq Utilities
When you enable ASR-2 to start into Compaq Utilities and a critical error occurs, the
operating-system-specific Health Driver logs the error information in the Compaq system
partition or the IML and the ASR-2 feature restarts the server. When the system reinitializes, the
system pages the designated administrator (if enabled), and starts Compaq Utilities from the
hard drive.
If Dial-In status is enabled, the modem is placed in auto-answer mode. If you enable Dial-Out
status, you are automatically enabled for Dial-In.
If Network Status is enabled, the appropriate network support software is loaded, depending on
the network protocol, IP or IPX. This allows remote access via the network.
IMPORTANT: Compaq Utilities are loaded from a specially created Compaq system partition on the hard
drive. This partition was configured during server configuration.
You can access the server and view the Integrated Management Logs remotely by modem,
in-band over the network, or directly from the server. For modem access, you must have either
Compaq Insight Manager 2.0 or above or have a VT100 or ANSI terminal type device. You
may use a standard CRT with VT100 or ANSI emulation capability, or you may use a PC with a
VT100 or ANSI terminal emulation package. The communication parameters must be set
for 8 data bits, no parity, and 1 stop bit.
You can also enable ASR-2 to allow network access using the Network Status feature in the
System Configuration Utility. You must have either Compaq Insight Manager 2.0 or greater or a
Novell Virtual Terminal (NVT) emulator on an IPX network to use this feature. You must also
have version 2.24 or later of the System Configuration Utility. For IP access, you must have
Compaq Insight Manager 2.10 or later, or a Telnet Terminal emulator to use this feature. You
also must have version 2.24 or later of the System Configuration Utility.
The System Configuration Utility settings should resemble the settings in Table 3-19 when you
enable ASR-2 to start into Compaq Utilities.

Boot Compaq Utilities. When the system starts because of an ASR reset,
it starts to the Compaq Utilities, sets the Management Modem to
auto-answer, and waits for the administrator to dial in and run the
Compaq Utilities.
You automatically disable this option when you configure the software
error recovery start option to Boot Operating System. When ASR pages
you, you cannot dial in unless ASR-2 exceeds 10, the threshold number
of server restart retries. When this happens, ASR-2 restarts the server
into the Compaq Utilities and places the modem in auto-answer mode.
Dial-out status
Enabled
Allows ASR-2 to dial out to a remote workstation. If you selected this
option, Dial-In Status is automatically selected.
To use the dial-out feature, set Dial-Out Status to Enabled and set the
Dial-Out String to the correct phone number. You must also set the
Reset Boot option to Boot Compaq Utilities. When the system restarts
because of an ASR reset, the administrator is paged via Pager Status
and Pager Dial String, the system restarts to the Compaq Utilities, and
dials out to the phone number provided in the Dial-Out string. The
dial-out number will be tried five times. If it fails to connect after five
attempts, the modem is put in auto-answer mode.

Booting into the Operating System
When you enable ASR-2 to restart into the operating system and a critical error occurs, ASR-2
logs the error in Integrated Management Log (IML) and restarts the server. The system ROM
pages the designated administrator, and then executes the normal restart process.
IMPORTANT: When you enable ASR-2 to restart into the operating system, Modem Dial-In Status,
Network Status, and Modem Dial-Out Status are automatically disabled. In this mode, ASR-2 can page
you if a critical error occurs, but you cannot access the server, and the server cannot dial out to a remote
workstation.
If the ASR-2 feature cannot restart the server within 10 attempts, it logs a critical error in the
Integrated Management Log (IML), restarts the server into the Compaq Utilities, and puts the
modem into auto-answer mode.
Diagnostics and Troubleshooting

ASR-2 Security
The standard Compaq password features function differently during ASR-2 than during a
typical system startup. During ASR-2, the system does not prompt for the power-on password.
This allows ASR-2 to restart the operating system or Compaq Utilities without user
intervention.
To maintain system security, set the server to start in Network Server Mode (an option in the
System Configuration Utility). This option ensures that the server keyboard is locked until you
enter the keyboard password.
Select an administrator password (an option in the System Configuration Utility). During
attended ASR-2 (local or remote), you must enter this administrator password before any
modifications can be made to the server configuration.

ASR-2 Integrated Management Log Messages
The Integrated Management Log (IML) records memory errors, as well as catastrophic
hardware and software errors that cause the system to fail. This information helps you quickly
identify and correct the problem, thus minimizing downtime.
You can view the IML through Compaq Insight Manager. The Diagnostics Utility either
resolves the error or suggests corrective action in systems that do not support event logs.
The IML or Compaq system partition identifies and records all the following errors. Each error
type is explained below.

Diagnostics and Troubleshooting
Storage Fault Recovery Tracking
This feature tracks over 12 failure-indication parameters, such as timeouts, spin-up, and self-test
errors of SCSI drives. You can use these parameters to pinpoint failed storage subsystem
components and to recover from controller or hard drive failure.
Storage Automatic Reconstruction
This feature automatically reconstructs data to an online spare or to a replaced drive if a drive
fails. To use the reconstruction feature, you must configure the server for drive mirroring or data
guarding. The reconstruction decreases system downtime by allowing rapid recovery to full
system operation if a drive fails.
Network Interface Fault Recovery Tracking
This feature tracks over 20 failure indication parameterssuch as alignment errors, lost frames,
and frame copy errorsof Ethernet and Token Ring network interfaces. It decreases network
downtime by enabling diagnosis of actual network interface failures.

Remote Service Features
Compaq servers have the following management features that you can access through a modem
or a network:
Table 3-23
Compaq Servers Remote Management Features
Feature
Description
Service Session
Provides remote access to all the utilities on the Compaq system partition,
including Diagnostics utilities, Inspect, ROMPaq, Drive Array Advanced Diagnostics
(DAAD), and the System Configuration Utility. Also provides the capability for
remote file transfer services to and from the Compaq system partition.
Disk-Based Diagnostics
Provides remote diagnostic capability after you configure ASR-2 and the reset
restart option to restart from Compaq Utilities. Also allows you to view Health Logs.
Disk-based diagnostics can also be run locally. Press F10 during the restart
process when the cursor moves to the upper-right corner of the monitor.
Server Restart
Provides the ability to restart the server remotely from Compaq Insight Manager
while the operating system is running. Allows the server to restart back to the
operating system or restart to the Compaq system partition. Provides a complete
system reset to all peripherals. If you select Boot to Compaq Utilities from Compaq
Insight Manager, Compaq Utilities loads the appropriate remote services so that
remote access is available. If network status is enabled, network support is loaded.
If Dial-In status is enabled, the modem is set to auto-answer.
Configuration Utility
Allows you to run the remote System Configuration Utility locally. Press F10 during
the restart process when the cursor moves to the upper-right corner of the monitor.
Firmware Updates
Allows you to update the server firmware remotely. Uses firmware images on the
Compaq system partition that might have been previously uploaded with the file
transfer services.
ROMPaq Error Recovery Options
From time to time it may be desirable to upgrade the current system ROM. Some reasons for
this may be as follows:
■
Customer desires ROM upgrade
■
Obtained new SmartStart CD-ROM
■
Desire to upgrade server processors
■
Request from Compaq
The process of upgrading the system ROM is referred to as flashing the ROM. Flashing consists
of using software to replace the current ROM image with a new one through ROMPaq.
Should an error such as a power failure occur during this process, the flash operation will not be
completed, causing the ROM image in the server to be corrupted. Compaq provides two options
for ROMPaq recovery, depending on the server and circumstances involved.
Diagnostics and Troubleshooting
ROMPaq Disaster Recovery
The following option should be utilized by any server that does not have a valid ROM image.
IMPORTANT: This operation should be performed on a server with redundant ROM ONLY IF both ROM
images have been corrupted. If only one image is corrupted, read the following section, “Redundant ROM
Image Recovery,” for complete instructions.
1. Build a fresh ROMPaq diskette, using the latest version for the server involved.
NOTE: If the ROM is corrupted by a ROMPaq interruption, the initial ROMPaq attempt may have affected
the contents of the original diskette.
2. Power down the server.
3. Set configuration switches 1, 4, 5, and 6 on the system maintenance switch block to On to
enable disaster mode.
Table 3-24
Configuration Switches

4. Insert the ROMPaq diskette. Although you will utilize a normal ROMPaq diskette, this
situation will not allow you to save the old image.
5. Power up the server. The keyboard, mouse and monitor are all inactive. The IMD is
active, if the server has one.
6. The server makes two long beeps, to indicate that you are in Disaster Recovery Mode, and
should insert the ROMPaq diskette. The IMD, if the server has one, displays:
Please insert ROMPaq diskette.
7. The server reads the diskette for the latest ROM image. If the diskette is not in place, the
system continues to beep until a valid ROMPaq diskette is inserted.
NOTE: The IMD will display the “Please insert ROMPaq diskette” message even after a valid ROMPaq
diskette has been installed – this is normal behavior. The server should stop beeping to indicate that the
diskette is a valid ROMPaq diskette.
8. The ROMPaq diskette flashes the system ROM. During this process, the IMD displays:
ROMPaq flashing system ROM.
9. At the successful completion of this process, the IMD displays:
ROMPaq flash successful—Cycle Power.
If the flash is not successful, the IMD displays:
ROMPaq flash failed.
3-65

Compaq ProLiant ML370 Maintenance and Service Guide
10. After successful completion of this process,
a. Power down the server
b. Remove the diskette.
c. Reset configuration switches 1, 4, 5 and 6. (Refer to Configuration Switches Table
within this section.)
d. Power up the server as usual.
After a failed ROMPaq, power down the server and repeat the above process.

Compaq Insight Management Software Architecture
The Compaq Insight Management software architecture is typical of other network management
solutions. It has a client/server architecture and is composed of agent software (Compaq Insight
Management Agents) and the management application software (Compaq Insight Manager).
Insight Management Agents
Insight Agents operate on Compaq systems (such as servers and workstations), performing
in-depth monitoring of the system’s state by collecting and measuring system parameters. These
parameters indicate the current state of subsystems by counting the occurrence of particular
events (for example, the number of read operations performed on a disk drive) or monitoring the
state of a critical function (such as whether the cooling fan is operating).
Insight Desktop Agents operate on Compaq Deskpro computers, monitoring functions that
include temperature sensing and disk prefailure alerting.
Insight Agents provide information to management applications, such as Compaq Insight
Manager, and can generate alarm notifications if significant changes occur in the fault or
performance aspects of system operation. Information is delivered to and from the Insight
Agents by the industry-standard Simple Network Management Protocol or SNMP.
Compaq Insight Manager
Compaq Insight Manager delivers intelligent monitoring and alerting as well as visual control of
the Compaq hardware. In the unlikely event of hardware failures, Compaq Insight Manager also
provides a full complement of remote maintenance and control facilities.
For additional information, refer to the online Compaq Insight Manager User Guide on the
server documentation CD that accompanied the server.

Switches
The Compaq ProLiant ML370 Server has two switchbanks (SW1 and SW2) located on the
system board. These switches are used to set the configuration of the server. The SW1 switch is
used as a system identification switch, and the setting is pre-set in the factory. Do not change
these settings. Incorrectly set switches may result in damage to the server.
