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.

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

Removal and Replacement Procedures 2-3

Any product or assembly marked with these symbols indicates that the component exceeds the recommended weight for one individual to handle safely.

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 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.

WARNING: To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system.

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.

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.

Removal and Replacement Procedures 2-5

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.

Table 3-1

Compaq Diagnostics Program

Compaq Inspect Utility

Compaq Insight Manager

Compaq Survey Utility

A utility to assist testing and/or verifying operation of Compaq hardware. If problems are found, Compaq Diagnostics isolates failure(s) down to replaceable part, whenever possible.

The Inspect Utility provides a report detailing system information.

A client/server application used to remotely manage Compaq hardware in a network environment. Reports hardware fault conditions (both failure and prefailure) and collects data for reporting and graphing.

An online information gathering agent that runs on servers, gathering critical hardware and software information from various sources. A utility for servers running Windows NT or NetWare.

If a significant change occurs between data gathering intervals, previous information is marked, and the survey text file is overwritten to reflect the latest configuration and changes since last configuration. This allows a historical record of change events for server hardware and software.

Diagnostics and Utilities are located on Compaq system partition (if installed) or your hard drive and must be accessed when a system configuration error is detected during Power-On Self-Test (POST). Compaq Diagnostics software is also available on Compaq SmartStart and Support Software CD. A Diagnostics diskette can be created from SmartStart and Support Software CD, and Diagnostics run from diskette.

The Inspect Utility can be run from either the main menu of the System Configuration Utility or the Compaq Diagnostics program.

For more information, refer to the Compaq Management CD and the Compaq Insight Manager User Guide.

More information on viewing and printing the event list can be found in the Compaq Insight Manager section of this chapter.

Array Diagnostics Utility (ADU)

Drive Array Advanced Diagnostics (DAAD)

Integrated Management Log

A Windows-based tool designed to run on all Compaq systems that support Compaq array controllers. Two main functions of ADU are to collect all possible information about the array controllers in the system and generate a list of detected problems.

This tool is available for all Compaq servers covered by this guide.

The predecessor to ADU, DAAD is a DOS-based tool for Compaq servers with Smart Array Controllers. DAAD collects information about the array controllers in the system and offers a list of detected problems.

A log of system events, such as system failures or nonfatal error conditions. View events in the Integrated Management Log:

■ On the Integrated Management

Display

■ From within Compaq Insight

Manager

■ From within Compaq Survey Utility

Use the information provided in Array Diagnostics Utility (ADU) later in this chapter.

For a list of Compaq servers still supported by this tool, visit the Compaq website:

www.compaq.com

The Integrated Management Log requires Compaq Operating System-dependent drivers. Refer to Compaq Support Software CD for instructions on installing the appropriate drivers.

System Configuration Utility

Utility to easily configure the hardware installed in or connected to the server. Specifically, it can:

■ Resolve resource conflicts in areas

such as memory, port addresses, and interrupts (IRQs)

■ Configure PCI boards automatically

■ Provide switch and jumper settings

■ Manage installation of memory,

processor upgrades, and mass storage devices such as hard drives, tape drives, and diskette drives

■ Store configuration information in

nonvolatile memory

■ Assist in installation of an operating

system

■ Assist in running diagnostic tools

such as TEST and INSPECT

If the server has bootable CD-ROM drive, run Compaq System Configuration Utility directly from Support Software CD supplied with Smart Controller Option Kit, or SmartStart and Support Software CD supplied with server. Use the CD supplied for latest version supporting Smart Controller.

If the server does not have a bootable CD-ROM drive, create diskettes with latest version of the System Configuration Utility from Support Software CD, or SmartStart and Support Software CD.

3-4 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

Diagnostics Software

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.

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.

Diagnostics and Troubleshooting 3-35

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.

Unknown disable code

Unrecoverable read error

WARNING— Drive Write Cache is enabled on X

Controller could not communicate with drive.

A code was returned from the Array Accelerator board that ADU does not recognize.

Read parity errors were detected when attempting to read same data from both sides of mirrored memory. Data loss will occur.

Drive has its internal write cache enabled. The drive may be a third-party drive or the operating parameters of the drive may have been altered. This condition may cause data corruption if power to the drive is interrupted.

If the amber LED on the drive is on, replace the drive.

Obtain the latest version of ADU.

Replace the Array Accelerator board.

Replace the drive with a Compaq supplied drive, or restore the operating parameters of the drive.

Warning bit detected

Write memory error

Wrong Accelerator

A monitor and performance threshold violation may have occurred. Status of a logical drive may not be OK.

Data could not be written to cache memory. This typically means that parity error was detected while writing data to cache. This could be caused by incomplete connection between cache and controller. This is not a data loss circumstance.

This could mean that either the board was replaced in the wrong slot or placed in a system that was previously configured with another board type. Included with this message is a message indicating the type of adapter sensed by ADU and a message indicating the type of adapter last configured nonvolatile RAM.

Check the other error messages on the diagnosis screen for an indication of the problem.

With power to system turned off, verify that the cache board is fully connected to controller.

Check the diagnosis screen for other error messages. Run the System Configuration Utility to update the system configuration.

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.
