v Diskette-free setup, and configuration programs that are based on detected
hardware
v ServeRAID Manager program, which configures your ServeRAID adapter or
integrated SCSI controller with RAID capabilities if installed
v A system BIOS update program, which updates the BIOS code directly from the
CD
v Device drivers that are provided for your server model and detected hardware
v Operating-system partition size and file-system type that are selectable during
setup
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 If installed, detects the SCSI RAID adapter, controller, or integrated SCSI
controller with RAID capabilities and runs the SCSI RAID configuration program.
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 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.
Chapter 2. Configuring your server 11
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 a server
with a ServeRAID adapter or integrated SCSI controller with RAID capabilities, 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:
– 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.
– 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 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
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.
12 xSeries 305 Type 8673: Hardware Maintenance Manual and Troubleshooting Guide
2. Diagnostics for your server come in BIOS code or on a separate diagnostics
CD.
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.

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 diskettes, the ServerGuide
program lists the diskettes that you must create and the optional device-driver
diskettes (for installed adapters or controllers) that you might want to create.
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.
Chapter 2. Configuring your server 13
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

Configuring the Gigabit Ethernet controller
Your server comes with two integrated Gigabit Ethernet controllers. The controllers
provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps local area
network (LAN) and provides full-duplex (FDX) capability, which enables
simultaneous transmission and reception of data on the network.
When you connect the server to a network, the Ethernet controllers detect the
data-transfer rate (10 Mbps, 100 Mbps, or 1 Gbps) of the network and automatically
operates at that rate. If the Ethernet ports that your server is connected to
auto-negotiation, the controllers automatically operate in standard Ethernet
(10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex (HDX), or full
duplex (FDX) mode. The controllers supports 1 GB speeds.
High-performance Ethernet options
The Ethernet controllers support teaming options, virtual LANs, and priority packets,
which improve performance, security, and throughput. These options are supported
by the integrated Ethernet controller and by adapters such as the IBM 10/100/1000
Ethernet Adapter and the IBM 10/100/1000 EtherJet PCI family of adapters.
Teaming options
The Ethernet controller supports teaming options. A team consists of two or more
integrated Ethernet controllers, two or more Ethernet adapters, or a combination of
Chapter 2. Configuring your server 15
Ethernet controllers and adapters. Teaming options improve throughput and fault
tolerance on a server running Microsoft Windows 2000, Windows NT 4.0, Linux, or
Novell NetWare 4.1x or later. The controller supports the following teaming options:
v Adapter fault tolerance (AFT) provides automatic redundancy for Ethernet
controllers. It supports from two to four controllers per team. You can configure
one of the integrated Ethernet controllers or adapters as the primary controller. If
the primary connection fails, the secondary controller takes over. When the
primary connection is restored, network traffic returns to the primary controller.
v Adaptive load balancing (ALB) balances data transmission among two to four
controllers. ALB includes AFT. You can use ALB with any 100BASETX/1000BASE-T switch.
v Cisco Fast EtherChannel (FEC) improves transmission and reception
throughput among two to four controllers. FEC includes AFT. You can use FEC
only with a switch that has FEC capability.

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 85 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 system might be part of a shared hard disk drive cluster (two or more
systems sharing one or more external storage devices). Before you run diagnostics,
verify that the failing system is not part of a shared hard disk drive cluster.
A system might be part of a cluster if:
v The system is identified as part of a cluster.
v One or more external storage units are attached to the system and at least one
of the attached storage units is also attached to another system or unidentifiable
source.
v One or more systems are located near the failing system.
If the failing system is suspected to be part of a shared hard disk drive cluster, you
can run all diagnostic tests except the diagnostic tests that test the storage unit
(hard disk drive residing in the storage unit) or the storage adapter attached to the
storage unit.
Notes:
1. For systems that are part of a shared hard disk drive cluster, run one test at a
time in looped mode. Do not run all tests in looped mode, because this could
enable the hard disk drive diagnostic tests.
2. If multiple error codes are displayed, diagnose the first error code that is
displayed.
3. If the computer stops with a POST error, go to “POST error codes” on page 69.
4. If the computer stops and no error is displayed, go to “Undetermined problems”
on page 77.
5. For power supply problems, see “Power checkout” on page 26.
6. For safety information, see “Safety information” on page 87.
7. For intermittent problems, check the error log.
