ServerGuide features
Features and functions can vary slightly with different versions of the ServerGuide
program. To learn more about the version that you have, start the ServerGuide
Setup and Installation CD and view the online overview. Not all features are
supported on all server models.
The ServerGuide program requires a supported IBM server with an enabled
startable (bootable) CD-ROM drive. In addition to the ServerGuide Setup and
Installation CD, you must have your operating system CD to install your operating
system.
The ServerGuide program has the following features:
v Sets system date and time.
v Detects an installed SCSI RAID adapter or controller and runs the SCSI RAID
configuration program. (Does not apply to the integrated SCSI controller with
RAID capabilities.)
v Updates the licensed internal code (firmware) level without diskettes.
v Checks the system BIOS code and microcode (firmware) levels of supported
options to determine whether a later level is available from the CD. You can
perform updates without using diskettes.
v Provides the Performance Optimizer program to easily tune your SCSI RAID
adapter settings for your server environment.
v Creates a System Partition on the default drive. You can run server-specific utility
programs after setup.
v Detects installed hardware options and provides updated device drivers for most
adapters and devices.
v Creates a setup-replication diskette for replicating setup selections for other
servers of the same model.
v Provides diskette-free installation for supported operating systems.
v Provides a replicated installation path for multiple installations of supported
operating systems.
v Includes an online README file with links to tips for your hardware and
operating system installation.
Setup and configuration overview
When you use the ServerGuide Setup and Installation CD, you do not need setup
diskettes. You can use the CD to configure any supported IBM server model. The
ServerGuide program checks your system BIOS, service processors, and other
system hardware to determine if system updates are available. The setup program
provides a list of tasks that are required to set up your server model. On SCSI
RAID servers, you can run the SCSI RAID configuration program to create logical
drives.
Note: Features and functions can vary slightly with different versions of the
ServerGuide program.
When you start the ServerGuide Setup and Installation CD, the program performs
the following tasks:
v The ServerGuide program prompts you for your language, country, and keyboard
layout. (This information is stored and later passed to the operating system
installation program.)
v The ServerGuide program displays choices for running the configuration
programs. For example:
12 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
– The Express Configuration method runs the required programs for your
server, based on the hardware that is detected.
– The Custom Configuration method displays all programs that are available for
your server, and you decide which programs to run.
– The Replicated Configuration method provides the option of duplicating your
setup selections to other servers that are the same model.
v If you select the Custom Configuration method, the following features are
optional. If you select the Express Configuration method, some or all of these
features are run, depending on the hardware that is detected:
– The Set Date and Time feature is provided so that you do not have to use the
Configuration/Setup Utility program to access these settings.
– The Clear Hard Disks feature is provided so you can delete all partitions on all
hard disk drives. If the server has a SCSI RAID adapter installed, you can
select to restore the configuration on the SCSI RAID adapter to the factory
default settings.
– The ServerGuide program checks the server BIOS code and microcode
(firmware) levels for supported options and then checks the CD for a newer
level. The CD content might be newer than the BIOS code and firmware level.
The ServerGuide program can perform a flash update of the BIOS code and
supported microcode (firmware) options without using diskettes.
– The SCSI RAID configuration program starts, leading you through the entire
configuration process.
– The Performance Optimizer program easily tunes your server for your
environment.
– The ServerGuide program creates a System Partition on the default drive.
v The ServerGuide program displays a confirmation summary, so that you will
know when you have completed all the required tasks. Then, you are ready to
install your operating system.
Notes:
1. Plug and Play adapters are configured automatically. Non-Plug and Play
2. Diagnostics for your server come in BIOS code or on a separate diagnostics
System Partition
The ServerGuide program creates a 50 MB System Partition on the default drive.
The System Partition contains server-specific utility programs such as service
processor disk operating system (DOS) utilities, system diagnostics, flash BIOS
updates, and other programs. Programs in the System Partition vary by server
model, and not all server models run utility programs from the System Partition. To
determine which ones do, start the ServerGuide Setup and Installation CD and view
the online overview.
After setup is complete, you can access programs in the System Partition by
restarting the server and pressing Alt+F1 when the prompt is displayed. The
System Partition menu displays the programs that are available on your server
model.
adapters or non-IBM adapters might require switch settings, additional device
drivers, and installation after the operating system is installed. See the
documentation that comes with the adapter.

Chapter 2. Configuring your server 13
Typical operating system installation
You can use the ServerGuide program to shorten your installation time. The
ServerGuide program provides the device drivers that are required for your
hardware and for the operating system that you are installing. This section
describes a typical ServerGuide operating system installation.
Note: Features and functions can vary slightly with different versions of the
ServerGuide program.
1. After you have completed the setup process, the operating system installation
program starts. (You will need your operating system CD to complete the
installation.)
2. The ServerGuide program stores information about the server model, service
processor, hard disk drive controllers, and network adapters. Then, the program
checks the CD for newer device drivers. This information is stored and then
passed to the operating system installation program.
3. With some operating system installations, you can create an operating system
replication diskette for setting up additional servers. This diskette contains the
Internet protocol (IP) address, server name, and other selections.
4. The ServerGuide program presents operating system partition options that are
based on your operating system selection and the installed hard disk drives.
5. If you are installing the operating system from diskette, the ServerGuide
program lists the diskettes that you must create and the optional diskettes that
you might want to create. The diskettes that you can create are the
device-driver diskettes for the installed adapters or controllers.
6. The ServerGuide program prompts you to insert your operating system CD and
restart the server. At this point, the installation program for the operating system
takes control to complete the installation.
Setting up or updating multiple servers
You can use the ServerGuide program to create diskettes that help you set up or
update multiple servers. You can modify information on the diskettes as you use
them to set up or update other servers.
Note: Availability and function can vary by server model and by the hardware that
is installed.
You can create a setup-replication diskette, which contains your hardware
configuration selections. Use this diskette to replicate selections to other servers
that are of the same model.
You can create an operating system replication diskette, which contains information
that you need to complete multiple installations. Not all operating systems support
operating system replication diskettes.
Installing your operating system without ServerGuide
If you have already configured the server hardware and you decide not to use the
ServerGuide program to install your operating system, complete the following steps
to download the latest operating system installation instructions from the IBM
Support Web page:
1. Go to http://www.ibm.com/pc/support/.
2. Under Browse, click Servers.
14 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
3. From the Family drop-down list, select your server model.
4. If operating system installation instructions are available for your server model,
OS installation is in the list in the upper-left corner of the Web page. Click OS
installation and select the instructions for your operating system.
Using ServeRAID Manager
You can use the ServeRAID™Manager program, which is on the IBM ServeRAID
Support CD, to:
v Configure a redundant array of independent disks (RAID)
v Restore a SCSI hard disk drive to factory-default settings, erasing all data from
the disk
v View your RAID configuration and associated devices
v Monitor operation of your RAID controllers
You can run ServeRAID Manager in startable-CD mode from the IBM ServeRAID
Support CD or as an installed program. For information about installing ServeRAID
Manager, see the documentation on the CD.
See the ServeRAID documentation on the IBM ServeRAID Support CD for
additional information about RAID technology and instructions for using ServeRAID
Manager. The Installation Guide for your server also contains instructions for using
ServeRAID Manager to configure your integrated SCSI controller with RAID
capabilities.
Notes:
1. The integrated SCSI controller with RAID capabilities in your server supports
only RAID level 1. Installing an optional ServeRAID-5i controller provides
additional RAID levels.
2. If you install a different type of RAID adapter in your server, use the
configuration method supplied with the RAID adapter to view or change SCSI
settings for attached devices.
Before you install your operating system, you must configure the controller that is
attached to the hard disk drives. Use the configuration program on the IBM
ServeRAID Support CD to configure the integrated SCSI controller with RAID
capabilities or to configure an optional IBM ServeRAID controller.
Notes:
1. You cannot use the ServerGuide Setup and Installation CD to configure the
optional controllers.
2. To update the firmware and BIOS code for an optional ServeRAID controller,
you must use the IBM ServeRAID Support CD that comes with the ServeRAID
option.
Using the LSI Logic Configuration Utility program
LSI Logic Configuration is a built-in, menu-driven configuration utility program that
you can use to:
v Perform a low-level format of a SCSI hard disk drive
v Set a SCSI device scan order
v View or change SCSI IDs for attached devices
v Set SCSI protocol parameters on SCSI hard disk drives
Chapter 2. Configuring your server 15
Notes:
1. The integrated SCSI controller with RAID capabilities in your server supports
redundant array of independent disks (RAID). You can use the LSI Logic
Configuration Utility program to configure RAID level 1 for a single pair of
attached devices.
2. If you install a different type of RAID adapter in your server, use the
configuration method supplied with the RAID adapter to view or change SCSI
settings for attached devices.
The following sections provide the instructions for starting and running the LSI Logic
Configuration Utility program and performing selected functions.
Starting the LSI Logic Configuration Utility program
Complete the following steps to start the LSI Logic Configuration Utility program:
1. Turn on the server.
2. When the prompt <<< Press <CTRL><C> to start LSI Logic Configuration
Utility >>> appears, press Ctrl+C. If you have set an administrator password
you are prompted to type the password.
3. Use the arrow keys to select a controller (channel) from the list of adapters;
then, press Enter.
4. Follow the instructions on the screen to change the settings of the selected
items; then, press Enter. The Device Properties and Mirroring Properties
choices produce additional screens of parameters to review or change.
Formatting a SCSI hard disk drive
Low-level formatting removes all data from the hard disk. If there is data you want
to save, back up the hard disk before performing this procedure. Complete the
following steps to format a drive.
Note: Before you format a SCSI hard disk, make sure that it is not part of a
mirrored pair. From the list of adapters, select the controller (channel) for the
drive to format. Select Mirroring Properties and make sure the mirroring
value for the drive is set to None.
1. From the list of adapters, select the controller (channel) for the drive to format.
2. Select Device Properties.
3. Use the arrow keys (↑ or ↓) to highlight the drive to format.
4. Use the arrow keys (← or →) or the End key to scroll to the right.
5. Select Format; then, press Enter to begin the low-level formatting operation.
Configuring the Gigabit Ethernet controller
The Ethernet controller is integrated on the system board. It provides an interface
for connecting to a 10-Mbps, 100-Mbps, or 1000-Mbps network and provides full
duplex (FDX) capability, which enables simultaneous transmission and reception of
data on the network. If the Ethernet port in the server supports auto-negotiation, the
controller detects the data-transfer rate of the network (10BASE-T, 100BASE-TX, or
1000BASE-T) and automatically operates at that rate, in full-duplex or half-duplex
mode, as appropriate. The Ethernet controller supports optional modes, such as
teaming, priority packets, load balancing, fault tolerance, and virtual LANs, which
provide better performance, security, and throughput. These modes apply to the
integrated Ethernet controller and to controllers on supported Ethernet adapters.
16 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
You do not need to set any jumpers or configure the controller. However, you must
install a device driver to enable the operating system to address the controller. The
device drivers are available on the Broadcom NetXtreme Gigabit Ethernet Software
CD. For the latest device drivers and information about configuring your Ethernet
controller, go to the IBM Support Web site at http://www.ibm.com/pc/support.

Chapter 3. Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your server.
If you cannot locate and correct the problem using the information in this section,
see Appendix A, “Getting help and technical assistance,” on page 129 for more
information.
General checkout
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs provide the primary methods of testing the major components of
the server.
If you cannot determine whether a problem is caused by the hardware or by the
software, you can run the diagnostic programs to confirm that the hardware is
working properly.
When you run the diagnostic programs, a single problem might cause several error
messages. When this occurs, work to correct the cause of the first error message.
After the cause of the first error message is corrected, the other error messages
might not occur the next time you run the test.
A failed server might be part of a shared DASD cluster (two or more servers
sharing one or more external storage devices). Before you run diagnostics, verify
that the failing server is not part of a shared DASD cluster.
A server might be part of a cluster if:
v The server is identified as part of a cluster.
v One or more external storage units are attached to the server and at least one of
the attached storage units is also attached to another server or unidentifiable
source.
v One or more servers are located near the failing server.
If the failing server is suspected to be part of a shared DASD cluster, you can run
all diagnostic tests except the diagnostic tests that test the storage unit (DASD
residing in the storage unit) or the storage adapter attached to the storage unit.
Notes:
1. For servers that are part of a shared DASD cluster, run one test at a time in
looped mode. Do not run all tests in looped mode, because this could enable
the DASD diagnostic tests.
2. If multiple error codes are displayed, diagnose the first error code that is
displayed.
3. If the server stops with a POST error, go to “POST error codes” on page 112
4. If the server stops and no error is displayed, go to “Undetermined problems” on
page 121
5. For power supply problems, see “Power checkout” on page 29
6. For safety information, see “Safety information” on page 131
7. For intermittent problems, check the error log.

Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v POST beep codes and error messages
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST error codes
and messages” on page 21 for more information.
v Error logs
The POST error log contains the three most recent error codes and messages
that the server has generated during POST.
The System Error Log contains all the error messages that were issued during
POST.
