Event log messages

Messages that are generated while the management module is monitoring the BladeCenter unit or by the BIST program during startup are displayed in the management module event log. Each message includes a severity level (error [E], warning [W], or information [I]), a source (such as, management module [SERVPROC] or blade server number [BLADE_xx]), a timestamp, and a text description.

When you are viewing the event log, consider the following information: v If the source of a message is a blade server, see the documentation that comes

with the blade server for more information.

v If the source of a message is not a blade server or the management module, see

the documentation that comes with the device for more information.

v By default, the entries are sorted by timestamp, with the most recent entry first.

You can sort the entries by severity, source, or timestamp by clicking on the appropriate column heading.

v You can filter the entries to show only the entries that match the severity, source,

or date you select.

v When a message identifies a specific component, use the following general

procedure to resolve the problem:

1. Check for lit LEDs on the component (see “Light path diagnostic LEDs” on

2. Reseat the component.

3. Replace the component.

v Review messages with earlier timestamps before taking action on a more recent

message. For example, an error message about a failing component with a recent timestamp may be related to an error message about the prior failure of another component.

v For some messages, when an problem has been resolved, the log will display a

message beginning with the word “Recovery” and followed by the same text as the original message.

Solving undetermined problems

If the diagnostic aids did not diagnose the failure or if the BladeCenter unit is inoperative, use the information in this section.

Note: When you are diagnosing a problem in the BladeCenter unit, you must determine if the problem is in the BladeCenter unit, one of the BladeCenter modules, or in a blade server.

v If the BladeCenter unit contains more than one blade server and only one of the

blade servers has the problem, troubleshoot the blade server that has the problem.

v If all of the blade servers have the same symptom, it is probably a BladeCenter

unit or module problem.

Check the LEDs on all the power modules. If the LEDs indicate that the power modules are working correctly, and reseating the BladeCenter components does not correct the problem, complete the following steps to remove or disconnect the BladeCenter components one at a time until you reach a minimal configuration or you locate the problem.

Note: You do not have to remove power from the BladeCenter unit.

1. Shut down the operating system on all blade servers.

2. Make sure that each blade server is turned off; then, pull the release handles to

the open position and slide it out of the bay approximately 1 inch.

3. Disengage power modules 2, 3, and 4, one at a time. To do this, pull the release handle to the open position and slide the power module out of its bay approximately 1 inch.

4. Disengage the I/O modules, one at a time. To do this, pull the release handle to the open position and slide the I/O module out of the bay approximately 1 inch.

Note: The following minimum configuration is required for troubleshooting the BladeCenter unit. See “Features and specifications” on page 4 for the minimum operational configuration.

v BladeCenter unit (media tray may be connected) v One power module in any power module bay v One management module in either management module bay v One blower module in either blower module bay

The BladeCenter unit can be checked with the management module Web interface at each stage as components are removed, and will work in the minimal configuration. If the minimal configuration does not work, do the following.

1. Recheck the management-module network settings.

2. Disengage the media tray, and slide it out of the bay approximately 1 inch.

Note: The front and rear panel LEDs will not function with the media tray removed.

3. Move the power module to power module bay 2.

4. Remove the power cords from the power connectors and reconnect them.

5. Replace the management module.

6. Replace the power module.

7. Replace the midplane.

Calling IBM for service

See Appendix A, “Getting help and technical assistance,” on page 61 for information about calling IBM for service.

When you call for service, have as much of the following information available as possible:

v Machine type and model v Microprocessor or hard disk upgrades v Failure symptoms

– Does the system fail the diagnostic programs? If so, what are the error codes? – What occurred? When? Where? Did it occur on a single or multiple systems? – Is the failure repeatable? – Has the current system configuration ever worked? – What changes, if any, were made before it failed? – Is this the original reported failure, or has this failure been reported before?

v Diagnostic program type and version level v Hardware configuration (print the screen with the system summary information) v BIOS code level v Operating-system type and version level

You can solve some problems by comparing the configuration and software setups between working and nonworking systems. When you compare systems to each other for diagnostic purposes, consider them identical only if all the following factors are exactly the same in all the systems:

v Machine type and model v BIOS code level v Adapters and attachments, in the same locations v Address jumpers, terminators, and cabling v Software versions and release levels v Diagnostic programs type and version level v Configuration option settings v Operating-system control-file setup

Chapter 4. Removing and replacing BladeCenter components

Replaceable components are of three types: v Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your

responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for the installation.

v Tier 2 customer replaceable unit: You can install a Tier 2 CRU yourself or

request IBM to install it, at no additional charge, under the type of warranty service that is designed for your computer.

v Field replaceable unit (FRU): FRUs must be installed only by trained service

technicians.

See Chapter 3, “Parts listing,” on page 23 to determine whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU.

For information about the terms of the warranty and getting service and assistance, see the Warranty and Support Information document.

Installation guidelines

Before you remove or replace a component, read the following information: v Read the safety information that begins on page v and “Handling static-sensitive

devices” on page 30. This information will help you work safely.

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v You do not have to disconnect the BladeCenter unit from power to install or

replace any of the hot-swap modules in the BladeCenter unit. You must to shut down the operating system and turn off a hot-swap blade server before you remove the blade server, but you do not have to remove power from the BladeCenter unit itself.

v Do not attempt to lift an object that you think is too heavy for you. If you have

to lift a heavy object, observe the following precautions: – Make sure that you stand safely without slipping. – Distribute the weight of the object equally between your feet. – Use a slow lifting force. Never move suddenly or twist when you lift a heavy

object.

– To avoid straining the muscles in your back, lift by standing or by pushing

up with your leg muscles.

v Make sure that you have an adequate number of properly grounded electrical

outlets for the BladeCenter unit.

v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver available. v Orange on a component or an orange label on or near a component indicates

that the component can be hot-swapped, which means that you can remove or install the component while the BladeCenter unit is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

Page 44

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the BladeCenter unit, open or close a latch, and so on.

v For a list of supported options for the BladeCenter unit, see

http://www.ibm.com/servers/eserver/serverproven/compat/us/.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that the following requirements are met:

v Each of the module bays on the front and rear of the BladeCenter unit has either

a module or a module filler installed.

v Each of the blade bays on the front of the BladeCenter unit has either a blade

server or a blade filler installed.

v Each of the drive bays in a blade server storage expansion option has either a

hot-swap drive or a filler panel installed.

v You have followed the cabling instructions that come with optional adapters. v A removed hot-swap module, blade server, or drive is replaced within 1 minute

of removal.

v Cables for the optional modules are routed according to the illustrations and

instructions in this document.

v A failed blower is replaced as soon as possible, to restore cooling redundancy.

Handling static-sensitive devices

Attention: Static electricity can damage the BladeCenter unit and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v The use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. v While the device is still in its static-protective package, touch it to an unpainted

metal part of the BladeCenter unit or rack for at least 2 seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it immediately without setting

down the device. If it is necessary to set down the device, put it back into its static-protective package.

v Take additional care when handling devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

Returning a device or component

If you are instructed to return a device or component, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.

Removing and replacing a blower module

Your BladeCenter might be equipped with standard blower modules (part number 44E5083), or it might be equipped with high-efficiency blower modules (part number 68Y8205). The standard and high-efficiency blower modules are not interchangeable and should not be mixed in the same BladeCenter unit.

Attention: Failed blower modules should only be replaced with the same type of blower module.

Note: Government regulations (such as those prescribed by Occupational Safety and Health Administration or European Community Directives) might govern noise level exposure in the workplace and might apply to you and your server installation. The actual sound pressure levels in your installation depend on a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room where you designate the racks to be installed; the noise levels from other equipment; the room ambient temperature; and employees' location in relation to the equipment. Compliance with such government regulations also depends on a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. It is recommended that you consult qualified experts in this field to determine whether you are in compliance with the applicable regulations.

Chapter 5. Configuration information and guidelines

This chapter provides information about updating the firmware, configuring the BladeCenter unit and its components, and networking guidelines.

Updating the firmware

The firmware for the management module and other BladeCenter components is periodically updated and is available for download on the Web. Go to http://www.ibm.com/support/ to get the latest level of firmware, such as BIOS code and device drivers.

Note: When replacing BladeCenter components, you might have to update the management module or other components with the latest version of firmware.

Configuring the BladeCenter unit

General configuration of the BladeCenter unit and installed components is performed through the management module. See the BladeCenter Management

Module User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for information and instructions. Some devices in the BladeCenter

unit, such as I/O modules and blade servers, might also require additional configuration. See the documentation that comes with each device for information and instructions.

Configuring the management module

All management modules are preconfigured with the same static IP address. You can use the management module to assign a new static IP address. To establish connectivity, the management module attempts to use Dynamic Host Control Protocol (DHCP) to acquire its initial IP address for the management-module Ethernet port. If DHCP is not installed or is enabled and fails, the management module uses the static IP address. Use the management module to configure other BladeCenter component settings, such as, user accounts, DHCP, or Wake on LAN. See the BladeCenter Management Module User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for instructions.

Configuring I/O modules

You must install and configure at least one external (in-band) port on an Ethernet switch module in I/O-module bay 1 or 2 to communicate with the Ethernet controllers that are integrated in each blade server. See the BladeCenter Management

Module User’s Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for information about configuring external ports on I/O modules.

For I/O-device settings, see the documentation that comes with your I/O device.

Note: If a pass-thru module is installed in I/O-module bay 1 or 2, you must configure the network switch that the pass-thru module is connected to; see the documentation that comes with the network switch.

Page 74

Configuring blade servers

To achieve communication redundancy on a blade server, you must configure the Ethernet controllers on the blade servers for failover. When failover occurs on a blade server, the secondary Ethernet controller takes over network communications, using the I/O module that is associated with that controller. Install a pair of Ethernet switches in I/O-module bays 1 and 2; then, configure them and your network infrastructure so that they can direct traffic to the same destinations. You can also install a pass-thru module that is connected to an external Ethernet switch in either or both of these I/O-module bays. See the documentation that comes with your blade server and operating system for instructions.

BladeCenter networking guidelines

Make sure that the network infrastructure is configured before you connect the BladeCenter unit to network.

Each blade server has two independent Ethernet controllers, each with its own MAC address and a dedicated 1000-Mbps link to one of the switch modules in I/O module bays 1 and 2. There is no internal data path between the two switches within the BladeCenter unit; an external network device is required for data packets to flow from one internal switch to the other.

The management module has a separate internal 100-Mbps link to each switch. These links are for internal management and control only. No data packets are allowed to flow from application programs on the blade servers to the management module over this path.

Processor speed indicates the internal clock speed of the microprocessor; other factors also affect application performance.

CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible maximum.

When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1024 bytes, MB stands for 1 048 576 bytes, and GB stands for 1 073 741 824 bytes.

When referring to hard disk drive capacity or communications volume, MB stands for 1 000 000 bytes, and GB stands for 1 000 000 000 bytes. Total user-accessible capacity can vary depending on operating environments.

Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives and population of all hard disk drive bays with the largest currently supported drives that are available from IBM.

Maximum memory might require replacement of the standard memory with an optional memory module.

Particulate contamination

Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the device that is described in this document. Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gases include damage that might cause the device to malfunction or cease functioning altogether. This specification sets forth limits for particulates and gases that are intended to avoid such damage. The limits must not be viewed or used as definitive limits, because numerous other factors, such as temperature or moisture content of the air, can influence the impact of particulates or environmental corrosives and gaseous contaminant transfer. In the absence of specific limits that are set forth in this document, you must implement practices that maintain particulate and gas levels that are consistent with the protection of human health and safety. If IBM determines that the levels of particulates or gases in your environment have caused damage to the server IBM may condition provision of repair or replacement of servers or parts on implementation of appropriate remedial measures to mitigate such environmental contamination. Implementation of such remedial measures is a customer responsibility.

Table 1. Limits for particulates and gases

Contaminant Limits

Particulate v The room air must be continuously filtered with 40% atmospheric

dust spot efficiency (MERV 9) according to ASHRAE Standard 52.2

v Air that enters a data center must be filtered to 99.97% efficiency or

greater, using high-efficiency particulate air (HEPA) filters that meet MIL-STD-282.

v The deliquescent relative humidity of the particulate contamination

must be more than 60%

v The room must be free of conductive contamination such as zinc

whiskers.

Gaseous v Copper: Class G1 as per ANSI/ISA 71.04-1985

v Silver: Corrosion rate of less than 300 Å in 30 days

ASHRAE 52.2-2008 - Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size. Atlanta: American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.

The deliquescent relative humidity of particulate contamination is the relative humidity at

which the dust absorbs enough water to become wet and promote ionic conduction.
