Safety Considerations

Before performing service procedures, review the following safety information.

Electrostatic Discharge

A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper packaging and grounding techniques are necessary 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 workstations with approved static-dissipating material. Use a wrist strap connected to the

work surface and properly grounded tools and equipment.

● Keep the work area free of non-conductive materials such as ordinary plastic assembly aids and

foam packing.

●

Always be properly grounded when touching a static-sensitive component or assembly.

● Avoid touching pins, leads, or circuitry.

● Use conductive field service tools.

4 Diagnostic Tools

This chapter is an overview of hardware, software, and firmware diagnostic tools that are available for configuring, monitoring, and managing HP BladeSystem PC Blade systems.

Diagnostic Software and Firmware Tools

The HP Integrated Administrator is a standard component of the HP BladeSystem PC Blade Enclosure system. The Integrated Administrator provides enclosure health, HP Blade PC health, and remote server manageability. Integrated Administrator features are accessed from any network-based client using a supported Web browser. In addition to other features, Integrated Administrator provides keyboard and mouse capability for an HP Blade PC, regardless of the state of the host operating system or host HP Blade PC.

Use the following tools to diagnose problems, test hardware, and monitor and manage HP BladeSystem PC Blade system operations.

Table 4-1 Diagnostic tools

Tool Description How to run the tool

HP Integrated Administrator (IA)

The HP Integrated Administrator is a centralized management and monitoring system for the HP BladeSystem PC Blade enclosure and HP Blade PCs. The Integrated Administrator acts as a combination web/console server and remote power controller, enabling in-band or out-ofband, secure, serial console connections to all HP Blade PCs in the enclosure.

Refer to the HP Integrated Administrated User Guide for complete details.

The Integrated Administrator keeps a system log resident and records and health diagnostic information provided by the blade PC. Additionally, the IA can receive additional status information from blade PCs equipped with a blade management controller (BMC) including network (PXE) boot status, diagnostic adaptor present, POST boot completion, front IO blanking mode, and ASR mode status (requires at least IA version 4.30 and BMC version 25h).

Automatic Server Recovery-2 (ASR-2)

ASR-2 automatically restarts a HP Blade PC after a catastrophic operating system failure.

With ASR-2, you have multiple recovery options:

●

Available Recovery provides software error recovery and environmental recovery.

●

Unattended Recovery logs the error information to the IA system log (IA version

4.2), resets the HP Blade PC, and tries to restart the operating system.

Run the ROM-Based Setup Utility and set ASR-2 to enable this tool.

26 Chapter 4 Diagnostic Tools

Page 33

HP Systems Insight Manager (SIM)

Systems Insight Manager is a client/server application used to remotely manage HP hardware in a network environment. SIM reports HP Blade PC and HP Blade PC Enclosure hardware fault conditions (both failure and prefailure) and collects data for reporting and graphing.

For more information on viewing and printing the event list, refer to the Management CD or the SIM User Guide.

ROM-Based Setup Utility (RBSU)

RBSU configures the hardware installed in or connected to the HP Blade PC. Specifically, it can:

● Store configuration information in

nonvolatile memory.

●

Manage memory installation, processor upgrades, network interface cards, and mass storage devices.

●

Assist in installing an operating system.

● Configure connectors and IRQs, if

required.

Attach a keyboard to the HP Blade PC using the diagnostic adapter.

Run RBSU by pressing the F10 key during POST.

BMCFlash Utility Update utility for the Blade Management

Controller (BMC) firmware..

Flash the BMC on BC2x00 blades only.

Hardware Diagnostic Tools

The HP BladeSystem PC Blade system offers the following HP Blade PC and HP PC Blade Enclosure hardware diagnostic tools.

Diagnostic Adapter

Use the diagnostic adapter(s) to attach peripheral devices to any individual HP Blade PC for local HP Blade PC diagnosis and management. See

Connectors, Switches, and LEDs on page 30 for the

location of diagnostic adapter connectors.

NOTE: You can hot-add peripheral devices using the diagnostic adapter if the devices support hot-

plug capability.

1. Power down the HP Blade PC (Powering Down a Blade PC on page 12).

2. Plug the diagnostic adapter into the diagnostic connector on the HP Blade PC (1).

Table 4-1 Diagnostic tools (continued)

When the Blade PC Does Not Start

This section provides systematic instructions on what to try and where to go for help for the most common problems encountered during initial Power On Self-Test (POST) of a blade PC. The blade PC must first complete this test each time you power up, before it can load the operating system and start running software applications.

If you have the same problem with several blade PCs, you may have an enclosure problem. See

When the enclosure does not start on page 50 .

If the blade PC does not start:

1. If the blade PC is rebooting repeatedly, be sure that the blade PC is not rebooting due to a

problem that initiates an Automatic System Recovery (ASR) reboot.

You can enable ASR to reboot your blade PC.

2. Reseat the blade PC.

NOTE: If the blade PC does not restart, proceed to Table 7-9 Blade PC Diagnostic Steps

on page 58in this appendix.

3. Check the blade PC for the normal power up sequence.

Do this by checking that the blade PC health LED turns to solid green. For location and function of the blade PC health LED, see

Powering Down a Blade PC on page 12.

4. Check the monitor (installed to the blade PC via the diagnostic adapter) for the following

messages that ensure that your blade PC meets the minimal hardware requirements and is powered up during normal operations:

●
