viii PC Server and Windows NT Integration Guide
This soft copy for use by IBM employees only.
Chapter 1. Introduction
Windows NT Server 4.0 is one of the major network operating systems available
on the market today, and is continuing to gain market acceptance. At the time of
publishing, previews are being shown of what may appear in version 5.0 of the
product. This demonstrates the fact the product is being developed and refined
to meet market demand.
Some features that set NT 4.0 apart from NT 3.51 include the following:
•
Revamped Windows 95 look and feel.
•
Integral DNS service.
•
Internet Server 2.0.
•
Front Page, a new Web publishing tool.
•
Several refinements to the system, with some major sections of code
rewritten to run faster.
In this redbook, we aim to demonstrate how easy and quickly NT 4.0 can be
installed on the range of IBM PC servers from the IBM PC Server 310 right up to
the IBM PC Server 704 and Server 720.
This book is not designed to teach you how to use Windows NT - it is assumed
that you are already familiar with the operating system. Rather, this book is
designed to aid you in installing and tuning NT 4.0 on your new IBM PC Server.
We have tested the installations on a variety of current and recent servers and
adapters so as to provide as much insight as possible into using the hardware
that you, the readers, are likely to have.
1.1 Where Windows NT is Heading
Naturally, Microsoft is continuing to enhance the operating system and is already
in beta test for the next version of the product, Version 5.0.
A press release dated November 4, 1996 announcing a preview of the Windows
NT Server 5.0 was shown to developers at Microsoft′s Professional Developer′s
Conference. It stated a number of enhancements to the product, including:
•
Active Directory
•
Active Server
•
Management Console
The full text of the press release can be found at URL:
http://www.microsoft.com/corpinfo/PRESS/1996/Nov96/MSNT5PR.htm
1.2 IBM and Windows NT
IBM continues to consider Windows NT to be one of the major network operating
systems of choice for its PC Server customers. To this end, IBM has committed
a large amount of resources to ensure that Windows NT runs at its best on IBM
hardware.
The Kirkland Programming Center is one of IBM′s major interfaces to Microsoft.
Located in Kirkland, Washington, the facility is five miles from Microsoft′s
Redmond campus, allowing quick access to the Microsoft team.
Copyright IBM Corp. 1997 1
This soft copy for use by IBM employees only.
The mission at the Kirkland Center is to adapt Microsoft′s products to IBM
hardware to satisfy customer requirements. This requires early involvement in
the design cycle, timely adaptation and porting, development of complimentary
software and drivers, extensive testing, and performance monitoring. The close
working relationship to Microsoft, both physical and personal, allows this to
happen. Kirkland has direct, high-speed data links to Microsoft that allow for
instant access to key databases residing on Microsoft Servers.
The center′s development and test teams are responsible for the porting efforts,
as well as developing and testing new software, drivers, and HALs (hardware
abstraction layers). The Kirkland technical support people help IBM′s marketing
and sales teams, and our defect support team provides Level 3 support to IBM′s
Help Centers around the world.
IBM has been a certified Microsoft Solution Provider since 1994, and was actively
involved in the early development of Windows NT Server 4.0. IBM is also
formalizing technical management and hardware compatibility arrangements
with Microsoft to speed the development of open solutions.
IBM became a certified Microsoft Compatibility Laboratory site for Windows NT
in April, 1996. Because we can perform our own Windows-logo certifications, we
can bring products to market sooner - and with far fewer system compatibility
problems. IBM is also one of eight companies world-wide to participate in the
Microsoft OEM Technical Management Program.
IBM PC Company is enhancing its use of Windows NT on its complete product
line. As well as PC servers, IBM desktop PCs are also certified for Windows NT.
The ThinkPad family provides simply the best mobile support for Windows NT in
the industry. The Aptiva family is anticipating Windows NT by moving device
drivers to the Windows Driver Model, to ensure portability between Windows 95
and Windows NT.
IBM software is also being written for or ported to Windows NT across the board.
Some software, such as the ServeRAID SCSI RAID adapter online management
tool runs on Windows NT and Windows 95. Most of IBM software development
teams that write code for the PC platform have or have plans for running their
applications and server code to run on Windows NT. This shows the
commitment IBM has to the operating system.
1.3 IBM PC Server and Windows NT Integration Guide
This redbook should help you install NT 4.0 on your IBM PC Server and provide
assistance with the monitoring of its performance in your production
environment and tune it to maximize the potential of your IT investment.
The following chapter discusses the configuration of the hardware itself, though
the use of SCSI and RAID utilities, CMOS setups and reference partitions.
Chapter 3 through Chapter 5 describe the process of installing Windows NT
Server 4.0 both with ServerGuide 3.0 and without.
Finally, Windows NT′s Performance Monitor and TME 10 NetFinity are then
discussed. We describe how to use them to monitor and tune the performance
of your server.

Chapter 2. Hardware Configuration
This chapter focuses on the setup and configuration of your IBM PC Server
hardware. The most common tasks are presented here. For more information
about these tasks, please see the user guides that came with your system.
The different technologies used to implement the PC Server family require
different methods for configuration. Unfortunately, there is no one common
configuration program that can be run on a machine to completely configure it.
In most cases, multiple programs will need to run in order to complete this
process.
This chapter gives instructions on using the various configuration programs and
when to use each one. There are some model dependencies, however. If you
see differences between what you see on your machine and what is documented
here, consult the user guides that comes with the system.
The configuration programs and a brief explanation of each are listed below:
•
BIOS setup
This program is used to configure system options on PCI/EISA/ISA machines.
The system options include such things as diskette and hard disk options,
video subsystem, and system memory.
•
EISA configuration utility
This utility is used to configure I/O adapters on machines with an EISA bus.
•
SCSISelect Utility
This utility allows you to configure the SCSI subsystem on PCI/EISA/ISA
machines. RAID subsystems are usually handled separately.
•
System Partition programs
These programs allow you to configure system options, I/O adapters, and the
SCSI subsystem on Micro Channel machines. They are either on the
reference partition of the server′s hard disk, or on a reference diskette, or a
combination of both.
•
RAID utility
This utility allows you to configure the RAID subsystem on machines
equipped with a RAID adapter.
These configuration programs are updated from time to time. The latest
versions can be found on IBM PC Company′s web site. Refer to Appendix A,
“Sources of Drivers and Information” on page 147 for more information.
2.1 The BIOS Setup Program
The setup program is used to configure system options on ISA and EISA
machines. The system options include such things as diskette and hard disk
options, video subsystem, and system memory. These parameters are
controlled by system BIOS and, hence, need to be modified before the operating
system boots.

EISA Configuration Diskettes
EISA adapters are shipped with a diskette that contains a configuration
file (a .CFG file) that the EISA configuration utility needs so that it knows
what parameters are available for the adapter. This .CFG file should be
copied to the EISA configuration diskette. If the file has been copied to
the diskette, the EISA adapter is added automatically.
If you have not copied the .CFG file, you will be prompted to insert the
adapter′s configuration diskette into the diskette drive during this process
and the .CFG file will be copied to your diskette.
Our token-ring adapter is recognized but not in the correct slot. This is
because it is not possible for EISA systems to determine what slot ISA
adapters are in. So we must tell the system what slot it is in by
adapter to the correct slot.

1 SCSI Parity Checking
Select this option to enable or disable SCSI Parity Checking on the host
adapter. If enabled, the host adapter will check parity when reading from
the SCSI bus to verify the correct transmission of data from your SCSI
devices. SCSI Parity Checking should be disabled if any attached SCSI
device does not support SCSI parity. Most currently available SCSI devices
do support SCSI parity.
Chapter 2. Hardware Configuration 13

2 Host Adapter SCSI Termination
All SCSI interfaces use daisy-chained cabling. The cable starts at the
adapter and goes to the first device, and then out of that device to the next
device and so on until it reaches the last device in the chain. The last
device has an incoming cable and a
terminator
absorb potential signal reflections on the SCSI bus that would cause
interference. The last device on the bus must always be terminated.
The SCSI-2 Fast/Wide PCI adapter that came with the PCI/EISA server has
three connectors that can be the starting points for a daisy-chained cable:
one 8-bit, 50-pin (SCSI-I) internal connector, one 16-bit, 68-pin (SCSI-II Wide)
internal cable connector, plus another 16-bit, 68-pin external connector. The
adapter has built-in terminators on these connectors.
The setting for the Host Adapter SCSI termination needs to be configured
depending on which connectors are used. This option is comprised of two
entries, a low and a high. You can think of them as software jumpers. Each
entry, low and high, can take on either an on or off value, thereby giving four
possible different combinations of the two entries. The chart below shows
the proper values of these entries depending upon which connectors have
been used.
. The terminators are used to

Only two of the three connectors can be used, either the two internal or
one internal and one external.

•
Press Enter to edit the value.
•
Use the arrow keys to select the new value or press Esc to quit.
•
Press Enter to validate the new value.
The fields in this panel are described below:
1 Initiate Sync Negotiation
The host adapter always responds to synchronous negotiation if the SCSI
device initiates it. However, when this field is set to Yes, the host adapter
will initiate synchronous negotiation with the SCSI device.
Some older SCSI-1 devices do not support synchronous negotiation. Set
Initiate Sync Negotiation for these devices to avoid malfunction.
2 Maximum Sync Transfer Rate
The default value is 10.0 MBps for SCSI-II Fast devices. If you are using
SCSI-II Fast/Wide devices, the effective maximum transfer rate is 20.0 MBps.
Older SCSI-1 devices do not support fast data transfer rates. If the transfer
rate is set too high, this may cause your server to operate erratically or
even hang. Select 5.0 Mbps for any SCSI-I devices.
3 Enable Disconnection
This option determines whether the host adapter allows a SCSI device to
disconnect from the SCSI bus (also known as the Disconnect/Reconnect
function).
You should leave the option set to Yes if two or more SCSI devices are
connected to optimize bus performance. If only one SCSI device is
connected, set Enable Disconnection to No to achieve better performance.
4 Send Start Unit Command
Enabling this option reduces the load on your server′s power supply by
allowing the SCSI devices to power-up one at a time when you boot the
server. Otherwise, the devices all power-up at the same time.
Chapter 2. Hardware Configuration 15
This soft copy for use by IBM employees only.
The SCSI-2 Fast and Wide Adapters issue the start unit command to each
drive one at a time. The SCSI-2 Fast/Wide Streaming RAID adapter issues
the start unit command to two drives at a time.
Note
In order to take advantage of this option, verify that the autostart jumpers
have been removed on hard drives. Otherwise, the drives will spin up
twice: once at Power on Reset (POR) time and again when the adapter
sends the start unit command.
5 Include in BIOS SCAN
This option determines whether the host adapter BIOS supports devices
attached to the SCSI bus without the need for device driver software. When
set to Yes, the host adapter BIOS controls the SCSI device. When set to No,
the host adapter BIOS does not search the SCSI ID.
Notes:
1. The Send start unit and Include in BIOS Scan options have no effect if BIOS
is disabled in the Advanced Configuration Options panel (see Figure 10).
2. Disabling the host adapter BIOS frees up 8-10 KB memory address space
and can shorten boot-up time, but you should only disable this option if the
peripherals on the SCSI bus are all controlled by device drivers and do not
need the BIOS (for example, a CD-ROM).
After completing the device configuration, there are a few more parameters that
need to be configured. To do this:

2.4 System Partition Programs
If you have a PCI/MCA machine, you will run the system programs. The system
programs are a set of utility programs you can use to configure the SCSI
subsystem, system options, and I/O adapters. Also, you can use them to set
passwords, change the date and time, and test the server. In effect, they are the
equivalent of Setup, EISA Configuration and SCSISelect for a PCI/EISA machine.
Chapter 2. Hardware Configuration 17

These programs are obtainable in several ways:
•
Shipped with the server on two diskettes called the reference diskette and
the diagnostic diskette.
•
Created from images for these diskettes on the ServerGuide CD-ROM that is
shipped with the system.
•
On the system partition of the machine.
Non-array systems are shipped with the system programs already installed
in a protected area of the hard disk called the system partition. The system
partition is protected against operating-system read, write, and format
operations to guard against accidental erasure or modification. Disk-array
systems do not have a system partition.
You can start the system programs in one of two ways:
1. Boot using the system partition.
2. Boot using reference diskette.
The system partition should be used if available. The reference diskette is
normally used to:
•
Configure and test disk-array models (since there is no system partition).
•
Test non-array models if you cannot start the system programs from the
system partition.
•
Reconstruct the programs on the system partition of a non-array model when
you replace the hard disk drive or if the programs are damaged.
•
To install the DOS keyboard-password program and other stand-alone utility
programs.

•
SCSI subsystem parameters
5 Set Features
This option allows you to set system parameters such as date and time, type
of console, startup sequence, fast startup mode, and passwords.
6 Copy an options diskette
Micro Channel machines use configuration files called adapter descriptor
files (.ADF files) in order to know what parameters and values are available
for the adapter. This option copies configuration and diagnostic files from
an option diskette to the system partition or to the backup copy of the
system programs diskettes. The server needs these files to make the new
options operational.
Attention!
This utility will prompt you for both the reference diskette and the
diagnostic diskette so that the proper programs can be copied from the
adapter option diskette to these diskettes. Make sure that you have
copies of both diskettes before you select this utility. These diskettes
can be obtained from Diskette Factory on the ServerGuide CD.

2 Change configuration
Change configuration allows you to change configuration information used
by the server. Use the Home, End, Page Up, Page Down, Up and Down
arrow keys to move from field to field, and F5 and F6 to scroll through the
choices. Use F10 to save the changes to non-volatile CMOS RAM.
If a setting conflicts with another, an asterisk (*) appears next to the conflicts
and the word conflicts appears at the right corner of the windows. You must
remove all conflicts before the configuration can be saved.
Note: Some settings are set by the system and cannot be overridden. The
user can change only those settings that have not been set by the system.
These are the settings enclosed in brackets (
[..]).
3 Backup configuration
This makes a copy of the configuration information stored in CMOS RAM to
the hard disk system partition or to the reference diskette. Back up the
configuration of your server every time an adapter is added, removed or a
configuration assignment is changed.
4 Restore configuration
This retrieves the configuration information that the user saved previously
with the backup configuration program and restores this information to the
CMOS RAM.
5 Run automatic configuration
This verifies and updates the configuration information. Use this program
after an adapter is added or removed or to configure the server. The
automatic configuration program sets system-board features first, and then
adapters one at time, starting with the lowest numbered slot.
After you use this choice, select Backup configuration to make a copy of the
new configuration information.
Notes:
1. Running automatic configuration resets parameters to their default
values.
2. This option can be used whenever the default values for adapters will be
adequate. If the default values need to be changed, then you must use
the Change configuration option discussed previously. Often, the
automatic configuration can be used as a starting point to ensure no
settings conflict. Then, the change configuration can be used to fine
tune any desired settings.
3. If you had a configuration where specific values were required and you
experience problems after running automatic configuration, you need to
change the parameters back to the required values.
6 Display memory map
This displays how memory in the address range 0C0000H through 0DFFFFH
is being used by any adapters installed in the server. It identifies each
device using this space by name and shows the addresses being used by
that device.

incoming call on the attached phone line.
B Real-Time Clock Power-On Mode
When this option is enabled, the server will turn on when the present
time matches the day and time values you have entered.
If you want the server to start only on a certain day of the month, type
the date in the space provided. If you want the server to start every
day, you must leave this field without a date. Figure 20 shows an
example where the server will be powered on the fifth day of every

Figure 21. Set Passwords and Security Features
Some of the features found on this panel are described below:
1 Set power-on password
This prevents unauthorized use of the server. After you set the power-on
password, a password prompt will appear each time the server is powered
on.
To use the server, type the correct password at the password prompt and
then press Enter. If the password was not entered correctly, you will see a
message that says the password was incorrect and you will be be prompted
to try again. If you do not enter the correct password after three tries, you
must turn the system off and then on again before further attempts are
possible.
Note
If you forget the power-on password, you can remove it by moving
jumper JMP1 on the system board. This jumper is located above the
memory connectors.
2 Change power-on password
This option displays the instructions for changing the current power-on
password, which are:
1. Turn off the server and wait a few seconds, then turn it on.
2. The following message will appear:
Enter password
Type the current password followed by a space, the new password
followed by a space, and the new password again.

3. Press Enter.
3 Remove power-on password
This option shows the instructions for removing the current power-on
password, which are:
1. Turn off the server and wait a few seconds, then turn it on.
2. The following message will appear:
Enter password
Type the current password followed by a space.
3. Press Enter.
Unattended Mode
If the unattended start mode is active, you must remove it before you can
change or remove the power-on password because the password prompt
does not appear when the unattended start mode is set.
4 Set unattended start mode
The unattended start mode locks the keyboard and mouse when the system
is powered on, but it allows the operating system and startup files to be
loaded. The keyboard and mouse remain locked until you enter the
power-on password.
This mode is useful for unattended operations and for network servers
because it allows authorized network users access to information on the
server but prohibits unauthorized access via the system keyboard and
mouse.
When the server is in the unattended mode, the password prompt will not
appear unless an attempt to start the system from a diskette or other
removable media is issued. If you start the server from a removable media,
the password prompt will appear and you must enter the correct power-on
password to continue.
Power-on Password
A power-on password must be set on the server before you can set the
unattended start mode because it locks the keyboard and mouse when
the system is powered on.
5 Set privileged-access mode
This option allows you to set a privileged-access password (also called an
administrator password). If set, this password is needed to start the system
programs.
Before the privileged-access password can be set, the privileged-access
switch at location JMP2 on the system board must be placed in the change
state (position 0).
Attention!
Do not forget the privileged-access password. If you forget this
password, the system board must be replaced before you can regain
access to your system.
Chapter 2. Hardware Configuration 31
This soft copy for use by IBM employees only.
6 Change privileged-access password
This option allows you to change the administrator password. You must
know the current privileged-access password in order to complete the
procedure.
7 Remove privileged password
This option removes the administrator password. You must know the
current privileged-access password in order to complete the procedure.
8 Set unauthorized-access monitor
If your system is equipped with a tamper-evident cover, you can select this
option to enable or disable the unauthorized-access monitor feature. This
feature works with the privileged-access password. If both features are
enabled, the server will alert you if someone attempts to tamper with the
locked covers. If tampering is detected, the actions taken are dependent
upon the operating system. Some possible actions include halting the
system and/or displaying and logging an error message.
If this feature is set and it then gets subsequently activated by cover
tampering, on the next boot, the system will display a message and force
the operator to enter the administrator password. If this password is not
entered correctly, the system will not come up.
2.4.1.8 Test the Computer
This option is the primary method of testing the system. It can be used to test
both the internal components of the system as well as the keyboard and some
external devices. The amount of time required to test all components depends
on the number of components. The more optional adapters and devices you
have attached to the server, the longer the testing takes.
If you cannot determine whether a problem is caused by the hardware or by
software, you can run the diagnostic programs to confirm that the hardware is
working properly. If a hardware problem is detected, an error message appears
explaining the cause of the problem and the action to take.
Note: If you start the system programs from the reference diskette and select
this option, a message prompts you to insert the diagnostic diskette.

2.4.1.10 Advanced Diagnostic Program
The advanced diagnostic program is intended to be used by trained service
technicians or very experienced users who can correctly interpret the advanced
diagnostic panel messages. It is an alternative method of testing the server.
An advantage of running the Advanced Diagnostic program is that if you suspect
a specific area of the server is causing a problem, you can choose to test only
that area. This will take less time than testing all of the components in the
server.
To start the Advanced Diagnostic program:
1. Start the system programs.

On non-disk array models, you have the option of formatting your hard disk
during the advanced diagnostic testing. The advanced diagnostic format
program is a low-level format program. It will completely reformat the disk,
which includes removing the system partition.
Depending on the hard disk capacity, the low-level format program could
take up to two hours.
Use the low-level format program in the following cases:
•
When you are installing software that requires a low-level format
•
When you get re-occurring messages from the diagnostic test directing
you to run the low-level format program on the hard disk
•
As a last resort before replacing a failing hard disk drive
•
If you want to erase the system partition
Servers with RAID Adapters
For non-disk array models, you must run the low-level format program
from the diskette.
For disk-array models, you must use the programs provided on the RAID
utility diskette to format the hard disk drives.

2.5 RAID Adapter Utilities
On PC Servers with SCSI RAID adapters, the RAID utility is used to configure the
attached SCSI devices. This section describes two of the utilities used on IBM
PC Servers:
1. The utility for the IBM SCSI-2 Fast/Wide Streaming RAID Adapter/A and the
IBM SCSI-2 Fast/Wide PCI RAID adapters. See 2.5.1, “SCSI-2 F/W PCI RAID
and Streaming RAID Adapter.”
2. The utility for the PC ServeRAID SCSI Adapter. Refer to 2.5.2, “PC
ServeRAID SCSI Adapter” on page 49.
2.5.1 SCSI-2 F/W PCI RAID and Streaming RAID Adapter
This utility comes on a bootable diskette that is shipped with every RAID Server.
Also, it can be rebuilt if necessary with the Diskette Factory option from the
ServerGuide.
The IBM RAID utility allows you to configure disk arrays as well as view the
status of the arrays already defined. It provides a graphical display of the
defined arrays and provides diagnostic information to assist you if a hard disk
within the array malfunctions.
The common configuration tasks that are described here are as follows:
1. Verify the configuration
2. Low-level format of the disks
3. Defining a hot-spare drive
4. Creating a disk array
5. Defining logical drives
6. Look at the drives information

Figure 28. RAID Configuration Program - Drive Information
The columns on the right show any devices attached to each channel on the
adapter. The box on the left shows information about a specific device. The unit
whose information is displayed is highlighted on the right.
Use the up and down arrow keys to display the information for other devices.
The RAID Utility shows device type and/or status for each device that it
recognizes. The devices may take on several states that you may encounter
when running the Utility.
Here is a list of indicators we used along with a description of each:
•
CDR = A CD-ROM device.
•
DDD = A hard disk which is defunct.
•
FMT = A hard disk which is being formatted.
•
HSP = A hard disk which ch has been defined as hot-spare drive.
•
OFL = A hard disk which is being used to rebuild a defunct drive. This is an
intermediate state between DDD and ONL.
•
ONL = A hard disk which has been assigned to an array.
•
RDY = A hard disk which is ready to use but not assigned to an array or
defined as hot-spare drive.
•
TAP = A tape drive.
•
UFM = A hard disk which is unformatted. The drive requires a low-level
format before it can be used.
2.5.1.2 Formatting the Disks
If your DASD devices appear as UNF, or if you have experienced some problems
with them, you can low-level format the disks.
If your disks appear as RDY, and you don′t want to reformat, then you can skip
over this section.

The following fields are configurable:
•
Stripe Unit Size
This parameter should be chosen such that the stripe unit size is close to the
size of the system I/O requests. The default is set to 8 KB.
Note: Once data is stored in the logical drive, the stripe unit cannot be
changed without destroying data in the logical drives.
40 PC Server and Windows NT Integration Guide
This soft copy for use by IBM employees only.
•
Rebuild Priority
This parameter sets the priority of the execution order of the rebuild I/O
requests with respect to the system I/O requests. The rebuild priority can be
changed without affecting data in the logical drive.
•
Parity Placement
Parity placement defines how parity is placed in the disk array with respect
to the data. F igure 32 shows the differences between left symmetric and
right asymmetric parity placement.
AAA-LLL are the data stripe units; PP0-PP3 are the corresponding parity
units.
Right Asymmetric (RA) Left Symmetric (LS)
Disk Disk Disk Disk Disk Disk Disk Disk
1 2 3 4 1 2 3 4
PP0 AAA BBB CCC AAA BBB CCC PP0
DDD PP1 EEE FFF EEE FFF PP1 DDD
GGG HHH PP2 III III PP2 GGG HHH
JJJ KKK LLL PP3 PP3 JJJ KKK LLL
Figure 32. Parity Placement in a RAID Subsystem
The default value is right asymmetric. In some situations, you may want to
try Left Symmetric to improve performance.
Note: Once a parity placement scheme is chosen and data is stored in the
logical drives, it cannot be changed without destroying data in the logical
drives.
•
Read-Ahead
Normally the IBM SCSI-2 Fast/Wide Streaming RAID adapter transfers data
from a disk to its local cache in steps of stripe unit size. This provides
excellent overall performance when workloads tend to be sequential.
However, if the workload is random and system I/O requests are smaller
than stripe unit size, reading ahead to the end of the stripe unit will result in
a wasted SCSI bus bandwidth and wasted disk utilization.
When Read-Ahead is set to Off, the size of data transfer from the disk to the
local cache is equal to the system I/O request size, and no read-ahead to the
end of the stripe unit size is performed.
Note: The Read-Ahead setting can be modified without destroying data in a
logical unit.

as a hot-spare and press Enter. The RDY status changes to HSP (hot-spare).
Figure 34 on page 43 shows an example where a hot-spare disk has been
defined.
3. Press Esc to validate.
Notes:
1. The hot-spare drive is not associated with any array. If more than one array
is defined, you need only one hot-spare drive for all the arrays.
2. If the disks have different sizes, the hot-spare drive must be the largest.

5. Press any key to return.
Now that an array has been defined, it is necessary to create the logical drives
on this array. Logical drive definitions for created arrays must be done before
exiting the Create/Delete Array menu.
Notes:
1. Up to four arrays can be defined per controller.
2. An array can be defined across the two channels of one controller.
3. You cannot define an array across two controllers.
4. For maximum performance and configuration flexibility, all installed drives
should be configured into a single-disk array. Where data separation is
desired, use separate logical drives on the same disk array. Each of these
logical drives will appear as a separate physical disk to software programs
like FDISK, and may be further divided into logical partitions. With this
approach, if additional physical drives are added at a later date, they can be
easily added as a second array without reconfiguring the original drives.

Notes:
a. If only one hard disk has been assigned to the array, RAID level 0 will be
automatically assigned and the pop-up menu does not appear.
b. If only two hard disks are assigned to the array, RAID-5 is not selectable,
since at least three hard disk drives in an array are necessary to assign
RAID level 5 to one of the logical drives.
c. Define any RAID-5 logical drives first. This is because the first logical
drive seen will be the first RAID-5 drive created and will be assigned
drive letter C. In this way, the operating system will be installed on a
RAID-5 drive.
d. The three RAID levels (0, 1 and 5) can be mixed in the same array
allowing the user to chose the optimum RAID level for each data type.
e. It is, however, not recommended to mix RAID-0 with the others levels if a
hot-spare drive is defined, since an automatic rebuild would not be
possible.
3. Assign the RAID level wanted and press Enter.
The logical drive size pop-up menu shows the space available in this array
for logical drives.
RAID-5 has been chosen in this example.

2.5.1.6 Setting the Write Policy
Now that the logical drives have been created, you may wish to change the write
policy for these drives.
If you want to change the write policy:
1. Select Advanced functions from the main menu.
2. Select Change write policy.
3. Use the up and down arrow keys to select the logical drive.
4. Press Enter to toggle the write policy.
The different options are as follows:
•
WB for Write-Back
In the write-back mode, the completion status is sent before the data is
actually written to the drives. While this mode will yield higher performance,
it is critical to protect the DASD power to ensure the write operations
actually complete, since the processor thinks the operation has been
completed.
•
WT for Write-Through
Chapter 2. Hardware Configuration 47
This soft copy for use by IBM employees only.
In write-through mode, the data is written directly to the disk and no
acknowledgement is sent until the operation is complete. This is the default.
2.5.1.7 Initializing the Array
If you are using RAID level 1 or 5, you must select Initialize logical drives for
proper operation. This sets the drive to a predetermined state. Any data existing
on the drive is overwritten with zeros, and the corresponding parity is initialized
to the correct value.
1. Select Initialize/synchronize array from the main menu.
2. Select Initialize logical drive.
3. Select the logical drive you want to initialize by pressing the spacebar.
4. Press Enter to start the initialization.
5. Select Yes to confirm.
2.5.1.8 Backup/Restoring the Configuration
The array configuration is stored on EEPROM on the adapter. It is very
important to back up this configuration on a diskette. If the adapter ever needs
to be replaced, the configuration can be restored to the new adapter without the
need to reconfigure the array. Otherwise, the array would need to be redefined
and your data would be lost.
This is important not only at installation time but whenever the array
configuration changes. For example, if a hot-spare drive is defined and
subsequently, a drive fails and the hot-spare is enabled, the array configuration
is updated. If you are unable to restore the configuration
before, it would have the same effect as re-initializing the arrays: all data would
be lost.

2.5.2 PC ServeRAID SCSI Adapter
The ServeRAID Adapter is a high-performance, three-channel PCI RAID adapter.
This technologically advanced RAID controller supports up to 45 SCSI-2
Fast/Wide or UltraSCSI hard drives to satisfy mission critical applications that
require protection for large amounts of data.
Adapter in Slot 1 (2.14)
│4. Change write policy │
│5. Format drive │
│6. Change RAID parameters │
│7. Exit │
└───────────────────────────────┘
The ServeRAID Adapter achieves outstanding performance through the use of a
RISC processor, 4 MB of cache, and a dual PCI bus architecture with a local PCI
bus. These attributes significantly improve system performance by reducing
traffic on the system local bus and by rapidly processing complex RAID
algorithms with a high-speed processor.
IBM incorporates logical drive migration with the ServeRAID Adapter. This new
technology allows changes to be made to the RAID configuration while the PC
Server is up and running. Using online utilities, new RAID arrays can be added
and RAID levels modified without deleting the original array, or requiring the
data to be restored from a backup source.
For added security, the ServeRAID Adapter stores critical RAID configuration
information in multiple locations on the adapter and hard disk making disaster
recovery or migrating hard drives from one server to another quick and easy.
This means hard drives can now be removed from your server and installed in
another server or external enclosure in any order. The ServeRAID Adapter
takes care of getting the configurations from the hard drives and remapping
them as necessary.
This adapter contains three internal connectors, one for each channel, and one
external connector. Three of the four connectors can be used for attachment of
SCSI devices.

2.5.2.1 ServeRAID Adapter Support Diskettes
Prior to publication, IBM released version 2.0 of the support diskettes for the
ServeRAID Adapter. The two major functional enhancements that this new
version provided are:
1. Internal Hot-Swap Drive Support for the IBM PC Server 704
The IBM PC ServeRAID SCSI Adapter is now supported on the IBM PC
Server 704, for both internal hot-swap disk drives and externally attached
hot-swap disk drives. This enhances the already-robust PC Server 704 and
adds flexibility to its RAID configurations.
To use the IPM PC ServeRAID SCSI adapter in the PC Server 704, the server
must be at BIOS Level 7 or higher and the PC ServeRAID SCSI Adapter
firmware and BIOS must be at Level 2.
2. Logical Drive Migration capabilities
Logical Drive Migration (LDM) for the IBM PC ServeRAID SCSI Adapter is
now available, extending the power and control of your IBM PC Server RAID
implementations.
The primary LDM functions allow you to add capacity to your RAID arrays by
increasing the size of the logical drives, or by creating additional free space
to create new logical drives.
The new LDM code provides the following functions:
•
Expand the array by adding up to three physical drives at a time. While
expanding the array, the logical drive size can be increased or kept
unchanged. While the logical drive size remains unchanged, the
increased space can be used to define additional logical drives.
•
Change the RAID level on-the-fly from RAID-0 to RAID-5 by adding a
drive and from RAID-5 to RAID-0 by removing a drive. All logical drives
in the array must be at the same RAID level.
•
Change RAID level on-the-fly from two-drive RAID-1 to RAID-5 by adding
one physical drive.
•
Concurrent I/O support: During the LDM process logical drives can be
accessed by users.
•
Degraded Mode support: While LDM is in progress and the logical drive
goes to Critical mode due to physical drive failure, LDM will continue to
run normally. LDM will not start if the logical drive is already in Critical
mode.
•
Power Failure Recovery: Should a power failure occur during LDM, the
operation restarts from the point of interruption when power is restored.
Logical Drive Migration functions are controlled from the ServeRAID
Administration and Monitoring Utility. Refer to 2.5.2.5, “Administration and
Monitoring Utility” on page 57 for information about this utility.
At the time of publication, the current levels of the ServeRAID software are:
•
ServeRAID Configuration Disk V2.00
•
ServeRAID Driver and Utility Disk V2.00
•
ServeRAID SCO BTLD Disk V2.00
•
ServeRAID Administration and Monitoring Utility V2.00
•
ServeRAID BIOS/Firmware V2.00

Images of these diskettes plus an online (HTML) version of the ServeRAID
Installation and User′s Guide are available from IBM′s PC Server Web site.
Refer to Appendix A, “Sources of Drivers and Information” on page 147 for
details.
2.5.2.2 IBM PC Server Support
To support the ServeRAID firmware, you should update the BIOS level of your
IBM PC Servers to the latest level. Refer to Appendix A , “Sources of Drivers
and Information” on page 147 for information on where to get the latest BIOS
code. As a minimum, the BIOS must be at the following BIOS levels:
Table 2. BIOS Levels Required for ServeRAID Adapter
Server BIOS Level Required
PC Server 310 Not Supported
PC Server 320 PCI/MCA 19A
PC Server 320 PCI/EISA M54PE-15T3
PC Server 325 All
PC Server 330 All
PC Server 520 PCI/MCA 19A
PC Server 520 PCI/EISA M54PE-15T3
PC Server 720 07
PC Server 704 7
PC Server 704 Considerations:
The 704′s internal drive bays are managed directly over the SCSI bus (rather
than through a separate DASD status cable) via an intelligent SCSI processor
device embedded in each internal hot-swap backplane.
All devices on a single SCSI channel must be assigned a unique ID. Since the
704′s internal backplanes are themselves SCSI devices, one of the SCSI IDs on
each of the ServeRAID adapter′s internal channels will be assigned to each
backplane. The PC Server 704 assigns each internal hot-swap backplane to
SCSI ID 6 (which corresponds to bay 7).
To view the ServeRAID′s current SCSI device ID assignments, please use one of
the ServeRAID utilities (such as the Configuration Diskette, the Monitor utility, or
the BIOS-based Mini-Config Utility). The bay/ID assigned to the backplane will
appear as a SBY (standby) or PRC (processor) device.
2.5.2.3 ServeRAID Configuration Utility
The configuration utility allows you to do maintenance on your ServeRAID
configuration. Boot from the diskette to run the utility. The main menu will
appear (Figure 42 on page 52):

Upon defining this configuration, EZ-RAID will automatically initialize and
synchronize your logical array.
Note: If you require a configuration other than these, you will need to
manually configure your arrays using Create/Delete/Copy.
4 Create/Delete/Copy
Select this option if you are configuring your system for the first time or if
you have added or removed a disk drive. More panels will be provided for
you to accomplish your task.
5 Initialize/Synchronize
Select Initialize/Synchronize logical drive if you want to prepare a freshly
created logical drive for use or if you want the system to recompute the
parity data in the drive.

2 Backup IPS ServeRAID Config; and
3 Restore/Convert Saved Config
These two options let you back up or restore the disk array configuration to
or from a diskette. This should be done when ever the configuration
changes (either manually by you, or automatically when a hot-spare is used
to replace a defunct drive).
Back up to Diskette!
We strongly recommend you back up your ServeRAID configuration to
diskette whenever a change is made.
The Restore/Convert option also helps you upgrade from a PCI RAID or
Streaming RAID adapter by converting your previous configuration.
Note: There are some limitations to this conversion option. See the
ServeRAID User′s Guide for more information.
4 Change Write Policy
Select Change write policy to configure a logical drive of an array to work in
either the write-through mode or the write-back mode. In the write-back
mode, the completion status is sent before the data is actually written to the
drives. Write-back mode generally provides higher performance with
increased risk of data loss in the event of power failure. In Write-through
mode completion status is sent after the data is written to the drives.
5 Change RAID Parameters
Change RAID Parameters allows you fine tune the RAID subsystem:
•
Stripe unit size - should be set to the size of I/O requests
•
Rebuild priority - specify which has higher priority: rebuild I/O or system
I/O
•
Auto rearrange - allows the adapter to resolve configuration related
conflicts automatically.
•
Read ahead - toggles the cache read ahead up to the end of stripe unit.

6 IBM RAID Subsystem Diagnostic
Select this option to run the ServeRAID Adapter self test. Low-level
formatting of drives is provided as well as a drive media test.
7 Init/View/Synchronize Config
This option lets you initialize the configuration of the adapter back to the
factory defaults. The ServeRAID Adapter stores critical configuration
information in a number of locations to ensure the data is not lost:
•
NVRAM on the adapter
•
EEPROM on the adapter
•
On each online (ONL) or rebuilt (RBL) drive
•
On diskette (upon request)
This option lets you view each of these stored configurations, and when a
discrepancy exists, you can select which one to use as a basis for
synchronization.
The RAID adapter also maintains a list of all changes to its RAID
configuration. A power-on change list, wrong SCSI ID list, and an
unidentified drive list are updated when devices are added or moved.
Changes to the devices′ state also affect these list. This option allows the
user to view all of this information.
8 Display/Change Adapter Params
Select Display/Change Adapter Params to display the adapter′s status or to
write a new adapter configuration Host ID. The adapter′s SCSI channel ID
and speed may also be changed.
2.5.2.4 Mini-Configuration Utility
The mini-configuration program is a quick way to display the adapter settings
and to perform a limited set of configuration functions without using the
configuration utility on diskette.
Upon booting the server with the ServeRAID controller installed, you will see:
Press <Ctrl+I> for MiniConfig Utility

Chapter 3. Pre-installation Considerations
This chapter is aimed at providing guidelines regarding hardware, software and
capacity consideration requirements when installing NT 4.0.
Windows NT Server 4.0 is a 32-bit operating system and is very hardware
intensive. With most 16-bit operating systems, such as DOS, hardware is not
accessed until it is required. Under Windows NT, hardware drivers are written to
and polled much more heavily for input/output (I/O) instructions. H ardware
problems that have gone unnoticed or have seemed to be minor under other
operating systems are likely to be amplified when running under Windows NT.
3.1 Hardware Requirements
The following are the minimum hardware requirements for installing NT 4.0:
•
16 MB of RAM
•
VGA level video support
•
Keyboard
•
IDE, EIDE, SCSI, or ESDI hard disk drive
•
486/25 processor or better
•
CD-ROM drive, 1.44 MB or 1.2 MB floppy disk drive, or active network
connection
•
Network card
IBM Adapters
Refer to Appendix D, “Tips on Windows NT and IBM Hardware” on page 155
for information about common problems found with IBM network adapters.
Although the minimum memory requirement is 16 MB, this offers only minimal
functionality. As a result, Microsoft recommends 32 MB of RAM or more.
Microsoft also recommends a 486DX2/50 or better processor. The minimum
space requirements for Windows NT Server 4.0 is 124 MB.
See 3.2, “Setup Options” on page 63 for more information.
Verify that there are no power-on self-test (POST) errors prior to starting the
installation process. Also, make certain that each adapter and peripheral device
is set to an independent IRQ, memory address, and DMA channel.
3.1.1 Enhanced IDE (EIDE) Drive Considerations
NT 4.0 supports only the following EIDE addressing schemes:
•
Logical Block Addressing (LBA)
•
ONTrack Disk Manager
•
EZDrive
•
Extended Cylinder Head Sector (ECHS)
Note: Only the IBM PC Server 310 has an EIDE controller as standard.
Copyright IBM Corp. 1997 61
3.1.2 Hardware Configuration
In order to successfully install Windows NT, we recommend that you obtain the
following information:
Adapter Card Required information
Video Adapter or chipset type
Network Card IRQ, I/O address, DMA (if used) connector type (BNC,
SCSI Controller Adapter model or chipset, IRQ and bus type
Mouse Mouse type, port (COM1, COM2, bus or PS/2(R))
I/O Port IRQ, I/0 address, DMA (if used) for each I/O port
Sound Card IRQ, I/O address, DMA (if used) for each card
Internal Modem card IRQ, I/O address, DMA (if used) for each modem
External Modem IRQ, I/O address, DMA (if used) for each modem
To aid you in obtaining this information, two utilities are provided on the
Windows NT installation CD-ROM: NTHQ and SCSITOOL.
3.1.2.1 The NTHQ Utility
NTHQ utility is provided on the Windows NT installation CD-ROM, which you will
find in the SUPPORT\HQTOOL directory. This utility will obtain most of the
necessary hardware setting information required to complete the installation.

3.1.2.2 The SCSITOOL Utility
Also on the Windows NT CD-ROM is the SCSITOOL utility for obtaining SCSI
information. This tool currently only supports SCSI adapters from Adaptec and
BusLogic. If you have all the required information it is not necessary to use this
utility.
Note: If you use a SCSI adapter that requires a driver diskette, such as the
ServeRAID Adapter, then this utility will not detect your SCSI subsystem.
To create the SCSITOOL bootable utility diskette, do the following:
1. Go to the X:\SUPPORT\SCSITOOL directory (where X: is you CD-ROM drive).
2. Insert a floppy disk in drive A:.

3.1.2.3 Unsupported Hardware
NT 4.0 does not currently support the following controller and BIOS
enhancements:
•
32-bit I/O BIOS switch
•
Enhanced drive access
•
Multiple block addressing or rapid IDE
•
Write-back cache on disk controllers
•
Power management features
3.2 Setup Options
There are three options you can use to install NT 4.0 that are supported by
Microsoft:
1. Standard Setup
Installing directly from the CD-ROM as described in Chapter 5, “Installing
Windows NT Server 4.0” on page 81 or from diskettes is almost always the
best method of setting up your Windows NT system. It offers the best
support for alternate Hardware Abstraction Layers (HALs), timing and
third-party drivers. If you have a supported CD-ROM drive, you should
choose this setup method. This installation method requires a minimum of
124 MB of free space.
This is the method we recommend for use with IBM PC Servers.
Creating Boot Diskettes?
If you misplace the setup disks for the standard setup, run either
/OX or WINNT32 /OX from the I386 directory on the installation CD-ROM to
create new boot disks for a standard setup.
You can also ServerGuide to build these diskettes. Refer to 4.3.2,
“AutoPilot” on page 76 for more information.
2. WINNT or WINNT32 Setup
This method was designed for network installations or for computers with
unsupported CD-ROM drives. It builds the boot disks and performs a file
copy of the setup directory to the hard disk drive before the setup procedure
begins. It is the second best choice after the standard setup. This
installation method also requires a minimum of 124 MB of free space.
See 3.2.2, “The WINNT Command” on page 64 for more information on the
WINNT command.
3. Installing over a Network
For networks where the Windows NT installation files are kept on a central
server, network installations can be accomplished using the WINNT
command or by copying the entire I386 directory from the setup CD-ROM to
the hard disk drive and then running
can reduce network traffic and dependency. The stability of your network
can have a detrimental impact on your installation process when installing
across the network. One of the more common problems is that the NetBIOS
protocol time-outs are set incorrectly. This will cause the installation
process to fail, especially if the server you are installing from is busy. If you
copying the entire I386 directory from the CD-ROM to the hard disk you will
need 223 MB of free space.
WINNT from the local disk drive. This
WINNT
Chapter 3. Pre-installation Considerations 63
See 3.10, “Installation Over the Network” on page 68 for more details.
Note: The method of copying the I386 directory can also be used when there
are drive or driver issues that otherwise block the use of the CD-ROM.
We used the standard setup method (option 1) in our testing.
3.2.1 Unsupported Setup Methods
WINNT /B or WINNT32 /B is used for a floppy-less setup. It copies the boot files to
the root of drive C and then uses the hard disk as if it were the boot disk. If you
have timing issues on your computer, such as problems accessing the hard disk
drive or similar error messages, this method can be used, but WINNT is much
more reliable. Please note that this method will fail if you are running
BIOS-level virus protection.
WINNT /W allows you to set up Windows NT from within Windows, bypassing the
drive locking and enhanced driver issues involved with a Windows NT setup.
Again, this bypasses many of the Windows NT setup safety features and is not
recommended.
WINNT /U is the command for unattended setup. This can only be used on
systems where all the components are standard and no user input is required. If
there are any problems, the setup will stop until the problem is resolved.
This soft copy for use by IBM employees only.
3.2.2 The WINNT Command
Windows NT includes both a 16-bit and a 32-bit version of setup. Both provide
the same basic functionality but the 32-bit version, WINNT32.EXE, will only run on
Windows NT and can be used to upgrade an existing installation of Windows NT.
The WINNT.EXE and WINNT32.EXE command line parameters are:
WINNT [/S[:]sourcepath] [/T[:]tempdrive] [/I[:]inffile] [/U[:scriptfile]] [/R[X]:directory] [/E:command]
Where the parameters have the following meanings:
[:]sourcepath Specifies the source location of Windows NT files. Must be a
/S
[:]tempdrive Specifies a drive to contain temporary setup files. If not
/T
[:]inffile Specifies the filename (no path) of the setup information file.
/I
/B Floppyless operation (requires /s).
/U Unattended operation and optional script file (requires /s).
/R: Specifies optional directory to be installed.
/RX Specifies optional directory to be copied.
/E: Specifies command to be executed at the end of GUI setup.

specified, setup will attempt to locate a drive for you.
The default is DOSNET.INF.
[path ] or \\server\share[\path]. The
/W Used with WINNT.EXE only for starting setup from within
Windows 3.x or Windows 95. The /B option is disabled in this
mode.
64 PC Server and Windows NT Integration Guide
This soft copy for use by IBM employees only.
3.3 Viruses
NT 4.0 will not install on a system infected by a virus.
One of the common problems associated with a virus infection rears it head
while you are busy installing, as described in Chapter 5, “Installing Windows NT
Server 4.0” on page 81. You may encounter an error stop (a blue screen with
error codes) right after the FAT file system has loaded. This symptom is usually
associated with a boot sector virus infection. The troubleshooting guide
documents several other errors caused by viruses. You can find the latest
troubleshooting guide from Microsoft at the following URL:
http://www.microsoft.com/kb
If your system is infected, use IBM AntiVirus to remove the virus prior to
attempting a Windows NT setup. You can create AntiVirus diskettes from
ServerGuide′s Diskette Factory. Refer to 4.3, “Serv erGuide Main Menu” on
page 73 for more information.
3.4 Disk Compression
3.5 HPFS Support
NT 4.0 will not access any drives if they are compressed by any method other
than the NTFS file compression in NT 3.51. All compression methods, including
Microsoft DoubleSpace, Stacker, or any other hardware compression method is
not compatible with NT 4.0.
In order to allow NT 4.0 to access data on a drive compressed with Microsoft
double space, you could run the following command to uncompress the drive. In
this example, C: is the boot drive.
COMPACT C:\ /U
Note: You will not be able to compress the root of the NT 4.0 boot drive. Any
upgrade or installation to the compressed root will fail.
The high-performance file system (HPFS) is no longer addressable or convertible
under Windows NT 4.0. If you have an HPFS volume, conversion must occur
prior to upgrading your system to Windows NT 4.0.
If there is no previous version of Windows NT on your system, and the data on
an HPFS partition needs to be accessed from Windows NT, you must back up the
data on the partition and reformat the partition to FAT or NTFS. S ome partition
information created for HPFS or the Boot Manager installation of OS/2 should be
removed using the tools they were created with. For example, use OS/2′s
FDISK.EXE to remove the Boot Manager partition.
3.6 Disk Partitioning
Microsoft recommends NT 4.0 be installed on a partition of at least 300 MB in
size, although we recommend a 400 MB or larger system partition.
We also suggest the boot partition be formatted as FAT for servers that do not
require C2 secure classification, and NTFS for those that do. This space is used
Chapter 3. Pre-installation Considerations 65
This soft copy for use by IBM employees only.
for the Windows NT code, page file and DOS or Windows 95 installation.
Formatting the boot partition with the FAT file system gives you the ability to
boot to DOS if necessary, to copy over drivers, or boot files in the event of a file
corruption or upgrade problem.
We recommend that all other partitions on your server be formatted with NTFS
for performance reasons.
Partition Size
DOS uses the FAT file system, which limits partitions to 2 GB. During the
installation process, Windows NT creates your boot partition as FAT and then
later converts them to NTFS if you requested it. As a result, Windows NT
imposes a 2 GB upper limit on the size of your boot drive partition.
We recommend that only one logical drive should initially be defined to install NT
4.0 because, in our experience, we have found that when defining more than one
logical drive, Windows NT may hang during the initial installation process.
Additional logical drives can be defined after the NT 4.0 installation is complete,
using Windows NT′s disk administrator.
We also recommend that any partitioning be performed under DOS prior to
starting the installation. The DOS FDISK program (compared to the NT 4.0
facilities during the setup phase) allows greater flexibility in deleting and
redefining partitions that already exist. A problem sometimes occurs when you
have previously defined partitions on your hard drive and you try to delete them
during the NT 4.0 installation process. You delete them but they do not show as
combined free space but as separate free space. That is, you are not able to
reclaim the free space as a single entity to create partitions that differ in size
from the original ones.
Tip
If your system is partitioned in such a fashion as to keep the operating
system and the data separate and you loose the administrative password,
you could destroy the partition where the operating system is installed.
Re-install Windows NT and take ownership of all the files on the data
partition.
This will give you access to the files but you will lose any security settings of
your system in the process. Depending on the way your system was
configured, you could lose all your data, so the method described should be
used as a last resort.
3.7 Plug and Play
Windows NT Server 4.0 does not use the plug and play BIOS features that the
IBM servers support. Plug and play support is planned for the next version of
NT.
The problem that you could encounter while the plug and play BIOS features of
your server is enabled occurs during the POST (power-on self-test). The plug
and play BIOS feature changes settings on the adapters to avoid any conflicts.
66 PC Server and Windows NT Integration Guide
This soft copy for use by IBM employees only.
NT 4.0 is not aware of any of these changes and the device drivers that address
these adapters will fail.
We recommend that, if possible, you should disable these BIOS features of your
server and on any adapters in the server.
Note: Some of the IBM PC Servers, such as the PC Server 320 have the ability
to disable the BIOS. This is usually in the advanced section of the BIOS utility.
Other servers, such as the PC Server 330 do not have the ability to disable plug
and play, however this should not present any problems.
3.7.1.1 Using Windows 95 to Install Plug and Play Devices
If you have a combination of devices that you find great difficulty in setting up
due to classes in interrupts, DMA settings or I/O addresses, you could try the
following (although they are tedious and time consuming).
Enable all the plug and play features of your devices as well as of the server.
Install Windows 95 and reboot the server several times. During this process,
Windows 95 will address the plug and play features and try to find the optimal
settings. This procedure works best if all the devices are plug and play enabled.
After you have established the correct hardware settings, disable the plug
features and proceed with the installation process as described in Chapter 5,
“Installing Windows NT Server 4.0” on page 81.
3.8 Upgrading from Windows 95
There is currently no provision made within NT 4.0 to upgrade from Windows 95.
This should be addressed in the upcoming release of Microsoft Windows NT 5.0.
It is unfortunate since most of the 32-Bit applications that run under Windows 95
will run under NT 4.0.
Note: You will have to check the documentation of the individual applications to
determine which of the Windows 95 applications will run under NT 4.0.
3.9 Upgrading from Windows NT 3.51
We recommend that you install NT 4.0 in a new directory instead of upgrading
your present version. There are some basic precautions that you have to
adhere to in order to make your upgrade successful:
1. We recommend that you start by making an ERD (emergency repair disk).
This can be done by running
directory. This will keep a safe copy of your user security database as well
as all the setting information of your server.
RDISK.EXE from the \WINNT\SYSTEM32\
Note: Remember to keep a note of the administrator password when you
make the ERD, as you might need it when you restore information from it.
Only the administrator password you choose at the time of making the ERD
will apply, even if you subsequently change the password.
2. Make a full backup of your server and remember to include the registry
information.
3. Make a note of all the installed devices and their hardware settings.
Chapter 3. Pre-installation Considerations 67
4. Find any device driver diskettes that pertain to adapters installed in your
server . If possible, try to establish by checking the time and date stamp of
the files if they are newer than any supplied with NT 4.0.
5. Refer to both the Microsoft and IBM hardware compatibility lists. These can
be found on the Web. R efer to Appendix A, “Sources of Drivers and
Information” on page 147 for the URLs.
6. Make a note of any IP addresses, server name, share names or any other
relevant information in case you have to rebuild the server.
7. Start the installation process as described in Chapter 5, “Installing Windows
NT Server 4.0” on page 81.
8. Proceed to the point in the installation process where you are asked whether
you want to install a fresh copy or you want to upgrade to the newer version.
Choose to upgrade.
9. Complete the installation.
3.10 Installation Over the Network
The preferred method of installing Windows NT is by using the installation
diskettes and CD-ROM provided by Microsoft. If you are unable to use this
method as described in Chapter 5, “Installing Windows NT Server 4.0” on
page 81, you could consider the method described below. This method is
intended to demonstrate how to install NT from an existing Microsoft NT network
server, workstation or Windows 95 device. It should deliver the same results as
the method described in Chapter 5, “Installing Windows NT Server 4.0” on
page 81, although it is slower.
This soft copy for use by IBM employees only.
1. Insert the NT 4.0 CD-ROM disk in a CD-ROM drive that you can connect to
from the new server. Alternatively, copy the contents of at least the I386
directory to a server.
2. Share the CD-ROM or data directory where you copied the NT code to to
allow the new server to access it.
3. Partition the new server by using the DOS
Note: Be careful to make sure that you specify the first partition as active;
otherwise, you will not be able to boot from it.
4. Format the first partition with the FAT file system using DOS or the Windows
FORMAT /S command.
95
5. Install the DOS network client on your server. You can find the DOS client
software on the NT Installation CD, in the \CLIENTS\ directory.
6. Reboot the new server and log on to the network.
7. Connect to the CD-ROM drive or directory in the existing server using the
NET USE command, for example:
FDISK.EXE utility.
NET USE * \\BIGMOTHER\I386
This will connect the first available drive letter to the I386 share located on
the specified server.
8. From the shared drive, enter the command

4.1 ServerGuide 3.0 and NT 4.0
For the purposes of this document, this chapter concentrates on the aspects of
ServerGuide 3.0 as it pertains to the installation of Windows NT Server 4.0.
For the installation of NT 4.0, ServerGuide provides assistance building driver
diskettes for the various IBM products and the installation diskettes for Windows
NT. However, you will have to make sure that the drivers that you create from
the ServerGuide CD-ROM are newer than those provided with the product. You
can do this by checking their time and date stamps.
Essentially the Windows NT installation diskettes created by ServerGuide are the
same as the disks supplied in the NT 4.0 CD-ROM retail packaging. If you have
all the necessary driver diskettes available for the hardware that you are
installing, you can proceed directly to Chapter 5, “Installing Windows NT Server
4.0” on page 81, which covers the installation process.
Note
The NT 4.0 code is not included in CD-ROM disks that are included in the
ServerGuide 3.0 package. You will have to supply a commercial version to
install NT 4.0.
This soft copy for use by IBM employees only.
4.2 Starting ServerGuide
Make sure that the write protect tab of the ServerGuide boot diskette is set to
write enable. ServerGuide needs to write to the diskette from time to time to
store information about your configuration and choices across reboots.
Write Protect Tab
If the write protect tab on the ServerGuide startup diskette is set to the write
protect position, the server will continuously reboot and ServerGuide will not
start. Ensure the diskette is write enabled.
To start ServerGuide, perform the following steps:
1. Insert the ServerGuide boot diskette.
2. Place the CD-ROM marked Main in the CD-ROM drive.
3. Power up or reboot the server.
Server Reboots
During this initial phase of ServerGuide, your server may reboot once or
twice. This is normal. These reboots are necessary as ServerGuide
adds a partition to your drive to accommodate the code it temporarily
installs to control the process.
4. Choose a language.
The first panel to be displayed after the booting process completes is the
one to select your keyboard and language, as shown in Figure 47 on
page 73.

5.2 Pre-installation Checklist
You should ensure you have done the following before you start:
•
Prepared your RAID array and initialized all logical drives created using the
RAID administration utility provided with the server.
•
Partitioned your logical drives. We recommend certain configuration

5.3 Installing NT 4.0
The installation process is divided into two components:
1. Hardware setup
2. Software/network setup
The first component is text-based and asks you to make selections, such as
hardware, disk controller, Hardware Abstraction Layer (HAL), and any
Copyright IBM Corp. 1997 81
partitioning that you may require. The second component, following a reboot,
sets up the software options and builds the networking environment for this
machine.
5.3.1 Starting the Process
Insert the NT 4.0 installation diskette 1 in drive A: and the NT 4.0 CD-ROM in
your server′s CD-ROM drive, and boot the server. When prompted, remove
diskette 1 and insert diskette 2. At the bottom of your panel, a message is
displayed indicating the progress of files loading and the files currently being
loaded.
Note
If your system error traps (a blue panel is displayed with error codes) after
loading the FAT file system, it is highly probable that your server is infected
with a boot sector virus. Use a commercial anti-virus application to disinfect
your server before continuing.
The Windows NT kernel starts and the initial setup panel appears (see
Figure 54).

Tip
Check the location (path) of the device drivers on the diskettes supplied by
the manufacturers before you start the installation process, as you will not
have the opportunity during the next section of the installation process.
NT 4.0 setup displays the following panel (Figure 55):
Windows NT Server Setup
=======================
Setup automatically detects floppy disk controllers and standard
ESDI/IDE hard disks without user intervention. However on some
computers detection of certain other mass storage devices, such as
SCSI adapters and CD-ROM drives, can cause the computer to become
unresponsive or to malfunction temporarily.
For this reason you can bypass Setup′ s mass storage device detection
and manually select SCSI adapters, CD-ROM drives, and special disk
controllers (such as drive arrays) for installation.
* To continue, press ENTER.
Setup will attempt to detect mass storage devices in your
computer.
* To skip mass storage device detection, press S.
Setup will allow you to manually select SCSI adapters,
CD-ROM drives, and special disk controllers for installation.
F3=Exit ENTER=Continue S=Skip Detection

Streaming RAID Adapter
In the Server 720 and Server 500, the Micro Channel SCSI-2 Streaming RAID
Adapter/A may not be correctly recognized by Windows NT. The symptoms
are that the operating system cannot find the CD-ROM drive.
The solution is to press S to skip detection of disk controllers and when
prompted insert the Driver/Configuration diskette in the drive to select “IBM
RAID Controller” instead.
See Appendix A, “Sources of Drivers and Information” on page 147 for
information on where to get the latest driver diskettes.
Press Enter to continue. Setup asks you to insert setup diskette 3 to continue
the device detection and installation process. At the bottom of the setup panel,
the device drivers currently being loaded is shown. Each detected adapter or
device is shown. For the PC Servers 325, 330 and 704, the panel shown is
similar to Figure 56 on page 84.
If the disk controllers that Windows NT detects are all the ones you have in your
server, press Enter to continue and proceed to 5.3.5, “System Analysis” on

Servers 325, 330 and 704; other servers are similar.
5.3.3 Specifying Additional Adapters
If the listed disk controllers do not include all the disk controllers in use in your
server, continue on here; otherwise skip to 5.3.5, “System Analysis” on page 88.
There are two major reasons why your disk controller may not have been
automatically detected:
1. You have more than one controller (for example, an integrated controller and
an adapter in a slot) and the controller detected was not the one you have
your disks attached to.
2. You have an adapter for which the driver required was not included on the
NT 4.0 CD-ROM (for example, the ServeRAID adapter).
In either instance, you will need to press S when the panel shown in Figure 56 is
displayed.

5.3.4 Potential Errors Detecting Disk Controllers
There are typically two possible reasons why unexpected messages occur at this
point:
1. No controllers or the wrong disk controllers listed.
If you have additional or other mass storage device adapters installed in
your server, you should supply any driver diskette supplied by the
manufacturers; otherwise, the installation process could fail. In addition, it is
a good idea before starting the installation process to check the location
(path) of the device drivers on the diskette.
Some manufacturers provide the drivers and the OEMSETUP.INF file on the
diskette′s root directory, others in a subdirectory usually called NT for the
Windows NT device drivers.
2. Incorrect installation diskettes used.
There are two possible sets of three installation diskettes that can be built by
running a program from the CD-ROM:
a. “Install from CD-ROM” diskettes, using the command
b. “Install from Network” diskettes, using the command WINNT /X
In this section, we are installing from the NT 4.0 CD-ROM, so the command
WINNT /OX (or WINNT32 /OX if running it from an existing Windows NT system)
should be used. If you use the
86 PC Server and Windows NT Integration Guide
WINNT /OX
/X switch when you wish to install from the
This soft copy for use by IBM employees only.
CD-ROM, the following two error panels are likely to occur at this point (see
Figure 60 on page 87 and Figure 61 on page 87).
Windows NT Server Setup
=======================
Setup has determined that your computers startup disk is new or has
been erased, or that an operating system is installed on your computer
with which Windows NT cannot coexist.
If such an operating system is installed on your computer, continuing
Setup may damage or destroy it.
If the hard disk is new or has been erased, or you want to discard its
current contents, you can choose to continue Setup.
. To continue Setup, press C. WARNING: Any data currently on your
computer′ s startup hard disk will be permanently lost.
. To exit Setup, press F3
C=Continue Setup F3=Exit
Figure 60. Detecting Freshly Configured Arrays
After pressing C, the following panel will appear (see Figure 61):
Windows NT Setup
================
Setup is unable to locate the hard drive partition prepared by the
MS-DOS portion of Setup.
When you run the MS-DOS Windows NT Setup program, you must specify a
temporary drive that is supported by Windows NT. See your System Guide
for more information.
Setup cannot continue. Press F3 to exit.
F3=Exit
Figure 61. Setup is Unable to Locate MS-DOS Partition
These panels appear because the incorrect command line parameters were
used when the installation disks were created for the CD-ROM installation.
You have boot-up diskettes that have been created using the
line parameters. These startup diskettes fail at this point because they are
expecting the installation process to have been started from a network drive
or directly from the CD-ROM after booting from DOS. If started in this
fashion, Windows NT creates two temporary directories on the temporary
partition and expects to be able to access the hard drives where the
temporary installation files have been transferred to. At this point, Windows
NT has not loaded the device drivers needed to access the RAID controller.
/X or command
Chapter 5. Installing Windows NT Server 4.0 87
To overcome the problem, recreate the installation disks. The correct syntax
is
This will correct the problem in most cases when the installation process is
restarted with the freshly created installation disks.
On the Windows NT Server Setup panel, press Enter if this information is correct,
or S to specify additional devices or adapters that you have in your server. You
will need to provide the driver diskette when prompted. If you pressed S,
continue reading. If you pressed Enter, go to 5.3.5, “System Analysis.”
5.3.5 System Analysis
At this point, all of the disk controllers should have been specified, either
automatically detected by Windows NT, or manually selected by you. The setup
program will now continue the installation process.
Windows NT will then load the required device drivers and the file system (NTFS)
drivers.
You may see the panel shown in Figure 62. This will appear if you have any
disks (or logical disks as defined in the RAID configuration) that are larger than
1024 cylinders (approximately 528 MB). Press Enter to continue. In most cases
you can ignore this message and Windows NT will work correctly with the IBM
disk controllers that it supports.
This soft copy for use by IBM employees only.
WINNT /OX from a DOS prompt or WINNT32 /OX while running NT 3.5 or later.
Windows NT Server Setup
=======================
Setup has determined that one or more of your hard disks has more than
1024 cylinders.
Because MS-DOS is normally limited to 1024 cylinders per hard disk,
some hard disk controllers offer special configuration options to
allow access to large disks in their entirety. These options are known
as sector translation modes. If a disk has only slightly more than 1024
cylinders, or such a mode is not enabled, a small portion of the disk
remains inaccessible to MS-DOS. Consult your computer or hard disk
controller documentation for more information about sector translation
and large hard disks.
If disk sizes appear too small when Setup later displays information
about hard disks it has located, you should exit Setup and check your
CMOS drive type settings. Consult your computer or hard disk controller
documentation for more information about CMOS drive type settings.
Note that this message does not necessarily indicate an error
condition. It is intended to alert you to the fact that one or more of
your hard disks may actually be larger than the size for which it is
currently configured.
Press ENTER to continue.
Enter=Continue

RAID Arrays and Logical Drives
Remember, when using drives attached to an IBM RAID controller, the
physical drives are combined into a RAID array. Within this array, you can
specify how much of the total available (drive array) disk space will be
assigned to a certain RAID level (RAID-0, -1 or -5). T his particular disk space
is called a logical drive. However, this logical drive is presented by the RAID
controller as a single disk drive to Windows NT. This (logical) drive needs to
be partitioned and formatted in the same fashion as any other disk drive.
