Default Configuration

When the system is first powered on, 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 your boot drive before running SmartStart and the System Configuration programs, this may prohibit creating a System Partition and the off-line remote management features that it provides.

If you insert a System Configuration, Diagnostics, or SmartStart CD in the CD-ROM drive prior to powering on the Server, the system ROM will boot to that utility. If the system ROM does not detect one of those Cds, you will be prompted for your intended operating system. The system will reboot 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 will boot normally. If you enter a wrong choice, on subsequent re-boots, you may change your operating system.

Utilities Access

The Compaq SmartStart and Support Software CD contains the SmartStart program and many of the Compaq utilities needed to maintain your system, including:

???System Configuration Utility

???Array Configuration Utility

???Drive Array Advanced Diagnostics Utility

???ROMPaq Firmware Upgrade Utilities

CAUTION: Do not select the Erase Utility when running the SmartStart and Support Software CD. This will result in data loss to the entire system.

There are several ways to access these utilities:

???Run the utilities on the system partition.

If the system was installed using SmartStart, the Compaq utilities will automatically be available on the system partition. The system partition could also have been created during a manual system installation.

To run the utilities on the system partition, boot the system and press F10 when you see ???Press F10 for system partition utilities.??? Then select the utilities from the menu.

???System Configuration Utility is available under the System Configuration menu.

???Array Configuration Utility is available under the System Configuration menu.

???Drive Array Advanced Diagnostics Utility is available under the Diagnostics and Utilities menu.

???ROMPaq Firmware Upgrade Utility is available under the Diagnostics and Utilities menu.

???Run the utilities from diskette.

You can also run the utilities from their individual diskettes. If you have a utility diskette newer than the version on the SmartStart and Support Software CD, use that diskette.

You can also create a diskette version of the utility from the SmartStart and Support Software CD. To create diskette versions of the utilities from the CD:

1.Boot the Compaq SmartStart and Support Software CD.

2.From the Compaq System Utilities screen, select Create Support Software ??? Next.

3.Select the diskette you would like to create from the list, then follow the instructions on the screen.

???Run the utilities from the Compaq SmartStart and Support Software CD.

IMPORTANT: Only the System Configuration Utility and the Array Configuration Utility can be executed from the Compaq SmartStart and Support Software CD. All other utilities must be executed only from the system partition or from diskette.

To run these utilities directly from the Compaq SmartStart and Support Software CD:

1.Start the Compaq SmartStart and Support Software CD.

2.From the Compaq System Utilities screen, select the utility you wish to run, and select Next.

???To execute the System Configuration Utility, select Run System Configuration Utility.

Power-On Self-Test (POST)

POST is a series of diagnostic tests that run automatically on Compaq computers when the system is turned on. POST checks the following assemblies to ensure that the computer system is functioning properly:

???Processors

???Keyboard

???Power supply

???System board

???Memory

???Memory expansion boards

???Controllers

???Diskette drives

???Hard drives

If POST finds an error in the system, an audible and/or visual message appears. If an error code appears on the screen during POST or after resetting the system, follow the instructions in Table 3-1. Error messages and codes listed in Table 3-1 include all codes generated by Compaq products. Your system generates only those codes that are applicable to your configuration.

The Action column lists the steps needed to correct the problem. After completing each step, run the Diagnostics program. If the error code reappears, perform the next step, then run the Diagnostics program again. Repeat this procedure until the error is corrected.

Diagnostics Software

Tables 3-2 through 3-20 include all test error codes generated by Compaq products. Each code has a corresponding description and recommended action(s). Your system generates only those codes that are applicable to your configuration and options.

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 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 CD and run Diagnostics from diskette.

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, listed in tables 3-2 through 3-20, help identify possible defective subassemblies.

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.

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

1.Be certain proper ventilation exists. The computer should have approximately 12 inches (30.5 cm) clearance at the front and back of the system unit.

2.Turn off the computer and peripheral devices.

3.Disconnect any peripheral devices not required for testing. Do not disconnect the printer if you want to test it or use it to log error messages.

4.Turn on the computer.

5.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, a forward slash ( / ), and press the Enter key.

6.Disable the power-on password by using the Password Disable switch on the system board, if you do not have access to the password.

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 Drive Array Controller. The error messages and codes listed include all codes generated by Compaq products. Your system generates only codes applicable to your configuration and options.

The two main functions of DAAD are:

???Collecting all possible information about array controllers in the system

???Offering a list of all detected problems

NOTE: Refer to the Drive Array Advanced Diagnostics User Guide, found on the SmartStart CD, 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, in 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.

3-45

Starting DAAD

To start DAAD:

1.Insert the DAAD diskette into drive A.

2.Reboot the system - OR - if you are at the DOS prompt, enter the following:

A:DAAD

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.

A dialog box is displayed, indicating the version of DAAD installed. Press the Enter (or ???C???) key to continue, or press the Esc (or ???E???) key to exit without continuing.

1.If you continue, a Please Wait panel is displayed, 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.

A second Please Wait panel may be displayed to indicate that the utility is identifying the ROM version of an array controller in the system.

CAUTION: Do not cycle the power; the utility 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.

When the information gathering process is complete, the main DAAD screen is displayed.

Integrated Management Log

On servers supporting the Integrated Management Display, Compaq Integrated Management Log (IML) replaces the Critical Error Log and Correctable Memory Logs. It records system events and stores them in an easily viewable form. It marks each event 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 non-fatal 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.

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 Compaq Survey Utility

???From within IML Management Utility

Integrated Management Display

The Integrated Management Display is a Liquid Crystal Display (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 server management tool providing in-depth fault configuration and performance monitoring of hundreds of Compaq servers from a single management console. System parameters that are monitored describe the status of all key server components. By being able to view the events that may occur to these components, you can take immediate action. You can view and print the event list from within Compaq Insight Manager by following the instructions that follow. You can also mark a critical or caution event as repaired after the affected component has been replaced. For example, when a fan that has failed has been replaced. By marking as repaired, you can lower the severity of the event.

3-70 Diagnostic Tools

Rapid Recovery Services

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)

???Server Health Logs (on servers not supporting Integrated Management Logs)

???Storage Fault Recovery Tracking

???Storage Automatic Reconstruction

???Network Interface Fault Recovery Tracking

???Memory Fault Recovery Tracking (with option upgrade kit)

These are discussed in more detail on the Systems Reference Library CD (SRL).

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 system partition.

You can tell ASR-2 to restart your server after a critical hardware or software error occurs. Using the Compaq System Configuration Utility, configure the system for either automatic recovery or for attended local or remote access to diagnostic and configuration tools.

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.Execute 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 time-out.

3-71

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.

ASR-2 tries to restart the server up to 10 times. 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 1850R Servers Maintenance and Service Guide

3-72 Diagnostic Tools

Hardware Requirements

To use this level of ASR-2 over a modem, you need the following:

???Compaq modem or optional Hayes modem

???System Configuration Utility and Diagnostics Utility installed on the 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

2.0or 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

2.10or 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 Critical Error Log. 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, your server restarts after a critical error and loads Compaq Utilities from the system partition on the hard drive.

You can configure your 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)

3-73

Compaq Integrated Remote Console

The standard Compaq Integrated Remote Console performs a wide range of configuration activities. Some of the console???s features include

???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 your server.

IMPORTANT: Before configuring ASR-2, verify that the System Configuration Utility and Diagnostics software are installed on the 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 lock-up, 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 the server downtime and allows the server to recover quickly. For local (attended) servers located onsite, you can set the software error recovery time-out 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 enabling 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 will record any information available about the condition of the operating system in the Critical Error Log, or the IML depending on the server support. This information can be used to diagnose an operating system crash or server lock-up, while still allowing the server to be restarted.

3-75

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 Critical Error Log 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 system partition on the hard drive. This partition was configured during server configuration.

You can access the server and view the Server Health Logs (in servers not supporting the IML) 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 either 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 the following table when you enable ASR-2 to start into Compaq Utilities.

Compaq ProLiant 1850R Servers Maintenance and Service Guide

Compaq System Configuration Utility Pager Settings for Booting into Compaq Utilities continued

If you configure the server to boot into Compaq Utilities, it prepares for remote communications. You can remotely run Diagnostics software, Inspect Utility, or System Configuration Utility using a workstation running terminal emulation software, such as Compaq Insight Manager or PC Anywhere.

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 the Critical Error Log or IML and restarts the server. The system ROM pages the designated administrator, and 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.

During the recovery process, the ASR-2 feature tries to restart the server up to 10 times. If the ASR-2 feature cannot restart the server within 10 attempts, it logs a critical error in the Critical Error Log or IML Log restarts the server into the Compaq Utilities, and puts the modem into auto-answer mode.

Your System Configuration Utility setting should resemble the following when you enable ASR to restart into the operating system:

Compaq ProLiant 1850R Servers Maintenance and Service Guide

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 the ASR-2 to restart the operating system or Compaq Utilities without user intervention.

To maintain system security, set the server to boot 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.

Server Health Logs

In some servers, Server Health Logs are replaced by the IML, if it is supported. See ???Integrated Management Display??? in this chapter for more information.

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

If errors occur, information about the errors is 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.

3-81

Critical Error Log

The Critical Error Log 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 Critical Error Log through the Compaq Insight Manager. The Diagnostics Utility either resolves the error or suggests corrective action in systems that do not support event logs.

The Critical Error Log identifies and records all the following errors. Each error type is briefly explained below.

Compaq ProLiant 1850R Servers Maintenance and Service Guide

3-84 Diagnostic Tools

Revision History Table

Some errors can be resolved by reviewing changes to the server configuration. The server has an Automatic Revision Tracking (ART) feature that helps you review recent changes to the server configuration.

One ART feature is the Revision History Table, which contains the hardware version number of the system board and any other system boards providing ART-compatible revision information. This feature lets you determine the level of functionality of an assembly in a system without opening or powering down the unit.

The Revision History Table is stored in nonvolatile RAM and is accessed through Inspect Utility and Compaq Insight Manager.

3-85

Storage Fault Recovery Tracking

This feature tracks over 12 failure-indication parameters, such as time-outs, 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 your 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.

Memory Fault Recovery Tracking

This feature inspects the operation of the memory subsystem looking for uncorrectable memory errors.

Compaq ProLiant 1850R Servers Maintenance and Service Guide

3-87

ROMPaq

Using flash ROM in Compaq servers allows the firmware (BIOS) to be upgraded with system or option ROMPaq utilities. To upgrade the ROM:

???Run the ROMPaq utility from the system partition, or

???Insert a ROMPaq diskette into drive A and cold boot the system.

The ROMPaq utility then checks the system and provides a choice (if more than one exists) of ROM revisions to which the system can be upgraded. This procedure is the same for both system and option ROMPaq utilities.

CAUTION: Do not turn the power off during a firmware upgrade. A loss of power during upgrade may corrupt the firmware and prevent the system from booting.

Compaq Insight Manager

Compaq Insight Manager is the Compaq application for easily managing network devices. Compaq Insight Manager delivers intelligent monitoring and alerting as well as visual control of your servers.

Features of Compaq Insight Management

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 pre-failure 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 your 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 Systems Reference Library CD that accompanied your server.
