1 Installation and Setup
The HP Ultra3 Single Channel SCSI Host Bus Adapter enables you to connect up to
15 SCSI devices—such as hard disk drives, scanners, and CD-ROM drives—to HP
Servers with 32-bit or 64-bit PCI expansion slots. You can connect newer Ultra3 and
Ultra2 SCSI devices to the two 68-pin Low Voltage Differential/Single-Ended
(LVD/SE) connectors. You can also connect legacy SCSI devices to the 68-pin and
50-pin internal Single-Ended (SE) connectors.
NOTE The HP Server tc2110 uses only Ultra3 SCSI devices

Chapter 1 Installation and Setup
Although the HP Ultra3 SCSI Host Bus Adapter is a 64-bit PCI host bus adapter, it
also works in a 32-bit PCI slot. When installed in a 32-bit PCI slot, the host bus
adapter automatically runs in the slower 32-bit mode. This installation guide
explains how to:
· Install the HP Ultra3 SCSI host bus adapter
· Set up SCSI devices
· Connect SCSI devices
Where to Obtain Installation Instructions
Complete installation and removal instructions can be found in both of the following
sources:
· The HP Server Operations and Maintenance Guide, on the HP Server Online
Documentation CD-ROM shipped with your HP Server, has a complete chapter
on installing and configuring the HP Server.
· The HP Server Operations and Maintenance Guide for your HP Server can be
viewed and printed from the official HP Server web site:
http://www.hp.com
Bus Segments on the HP Ultra3 SCSI Host
Adapter
The HP Ultra3 SCSI host bus adapter features technology that ensures you get the
best performance from your Ultra3 and Ultra2 SCSI devices by electronically
isolating the primary LVD/SE segment from the secondary SE segment on the SCSI
bus. This allows the HP Ultra3 SCSI host bus adapter to support newer Ultra3 and
Ultra2 SCSI devices at speeds up to 160 MBytes/sec on the primary LVD/SE
segment while at the same time supporting Ultra (legacy) devices at speeds up to 40
MBytes/sec on the secondary SE segment. The following figure shows the two SCSI
segments.

Chapter 1 Installation and Setup
Primary LVD/SE Segment
Figure 1-2. Primary and Secondary Bus Segments
Secondary LVD/SE Segment
NOTE If you attach Wide Ultra or Ultra SCSI devices to the LVD/SE
connector(s), the data transfer rate for all attached Ultra3 and
Ultra2 SCSI devices will drop to Ultra SCSI performance
levels. However, if you attach only Ultra3 and Ultra2 SCSI
devices to the LVD/SE connector(s), data will be transferred at
the maximum possible rate (80 MBytes/sec for Ultra2 devices
and 160 MBytes/sec for Ultra3 devices).
Installing the HP Ultra3 SCSI Host Bus Adapter
1. Discharge any static electricity build-up before handling the SCSI host bus
adapter by touching a grounded metal object (like the exposed metal parts on the
back of your HP Server).
WARNING Turn OFF power to the HP Server and disconnect the power
2. After you turn off your HP Server and unplug the power cord, remove the cover
from the Server.

3. Locate an unused 64-bit PCI expansion slot and remove the expansion slot
cover. If the HP Server does not have a 64-bit slot, you can install the host
adapter in a 32-bit PCI slot. (The expansion slot must be compliant with PCI
Rev. 2.1 or higher and must support bus mastering.)

Chapter 1 Installation and Setup
Figure 1-4. Host Bus Adapter Installed in 64-bit Slot
HP Servers may have vertical or horizontal expansion slots. Refer to your HP Server
manual to locate the PCI slots.
NOTE Be careful when inserting the HP Ultra3 SCSI host bus
adapter in a PCI slot. Some 32-bit slots will not accommodate
it, and the host adapter may break if you force it into the slot.
4. Insert the HP Ultra3 SCSI host bus adapter into the PCI expansion slot; press
down firmly until the host adapter clicks into place, then replace the slot cover
screw. When installed properly, the host adapter should appear level with the
expansion slot, as shown above.

Chapter 1 Installation and Setup
Setting Up SCSI Devices
There are several things you may need to do to your SCSI devices before you
connect them to the HP Ultra3 SCSI host bus adapter:
· Check the SCSI IDs
· Set the termination
· Connect the power cables
Since setup can vary from device to device, always refer to the device’s
documentation for specific instructions.
Below are some guidelines for setting SCSI IDs and termination on your devices.
Check the SCSI IDs
The HP Ultra3 SCSI host bus adapter and each device you connect to it must have a
unique SCSI ID number ranging from 0 to 15. No two devices can have the same ID
number. The HP Ultra3 SCSI host bus adapter is preset to SCSI ID 7 and should not
be changed. If your HP Server will boot from a SCSI hard disk, make sure the SCSI
ID of that hard disk is set to 0. (Most SCSI hard disks are preset to SCSI ID 0 at the
factory.) The SCSI IDs for internal devices are usually set with jumpers; SCSI IDs
for external devices are usually set with a switch on the back of the device.
Terminate the Ends
To ensure reliable communication on the SCSI bus, the device at the end of each
cable, or the end of the cable itself, must have a terminator installed (or enabled).
Terminators must be removed, or termination must be disabled, on devices between
the ends of each cable.
Connecting SCSI Devices
You can connect up to 15 SCSI devices to the HP Ultra3 SCSI host bus adapter.
Before connecting devices, be sure to review “Setting Up SCSI Devices” on page 6.
Connecting the SCSI Host Adapter to the Common Tray
Connect internal Ultra3 SCSI devices to the internal LVD/SE connector on the HP
Ultra3 SCSI host bus adapter. Follow these steps to connect the devices:
1. Use a terminated twisted-pair SCSI cable.
2. Plug the non-terminated end of the twisted-pair cable to the internal LVD/SE
connector (Figure 1-5).

Chapter 1 Installation and Setup
Connecting External SCSI Devices
Connect external Ultra3 SCSI devices to the 68-pin external LVD/SE SCSI
connector. Each external device will require a high density 68-pin external LVD
SCSI cable.
Follow these steps to connect the external devices:
1. Connect one end of the external LVD SCSI cable to the external LVD/SE
connector on the HP Ultra3 SCSI host bus adapter.
Figure 1-7. Connecting External SCSI Devices
2. Connect the other end of the external SCSI cable to a SCSI connector on the
back of an external SCSI device. If you are installing only one external device,
terminate the device and skip to Step 4.
3. Connect other external devices by cabling each device to the previous one, as
shown below.
8
Chapter 1 Installation and Setup
Figure 1-8. Terminating the Last External SCSI Device
4. Terminate only the device at the end of the chain. (Use of an external
multi-mode SCSI terminator is required.)
5. Connect power cables to all external devices and to the HP Server.
HP Ultra3 SCSI Host Adapter Driver Software
NOTE To use the HP Ultra3 SCSI host bus adapter, driver software
must be installed for your operating system.
Preloaded Ultra3 Drivers
If the HP Ultra3 SCSI host bus adapter was included as part of an HP Server you
purchased, then the appropriate HP driver has already been pre-installed by HP and
you do not need to install it.
Embedded Ultra3 Drivers
Some operating systems have embedded driver support for the HP Ultra3 SCSI host
bus adapter. To determine if the host adapter is supported by the operating system
you are using, read the operating system manual or contact the operating system
vendor for information.

Chapter 1 Installation and Setup
Troubleshooting
If you have any problems while installing the HP Ultra3 SCSI host bus adapter,
check the following items first:
· Are all SCSI devices powered on?
· Are all SCSI cables and power cables properly connected?
· Does each device on the SCSI bus have a unique SCSI ID?
· Does the total SCSI cable length exceed the maximum allowable length? (The
maximum cable length for the Ultra3 SCSI host adapter cannot exceed 12
meters.)
· Is the SCSI bus properly terminated?
If you are still unable to resolve a problem, contact HP Technical Support for help.

Chapter 2 Configuration with SCSISelect
SCSI Bus Interface Definitions
· Host Adapter SCSI ID—(Default: 7) Sets the SCSI ID for the SCSI host bus
adapter. The Ultra3 SCSI Host Bus Adapter is set at 7, which gives it the highest
priority on the SCSI bus. We recommend that you do not change this setting.
· SCSI Parity Checking—(Default: Enabled) When set to Enabled, verifies the
accuracy of data transfer on the SCSI bus. Leave this setting enabled unless any
SCSI device connected to the Ultra3 SCSI Host Bus Adapter does not support
SCSI parity.
· Host Adapter SCSI Termination—(Default: Automatic) Determines the
termination setting for the SCSI host bus adapter. The default setting for both
the LVD/SE and SE connectors is Automatic, which allows the SCSI host bus
adapter to adjust the termination as needed depending on the configuration of the
connected SCSI devices. We recommend that you do not change this setting.
Boot Device Options
· Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot device. We
recommend that you do not change the default setting.
· Boot LUN Number—(Default: 0) Specifies which LUN (Logical Unit
Number) to boot from on your boot device. This setting is not valid unless
Multiple LUN Support is Enabled (see “Advanced Configuration Options” on
page 16).
SCSI Device Configuration
SCSI Device Configuration options can be set individually for each connected SCSI
device.
NOTE To configure settings for a SCSI device, you must know its
SCSI ID (see “Using SCSI Disk Utilities” on page 18).
· Sync Transfer Rate—(Default: 160) Determines the maximum synchronous
data transfer rate that the SCSI host adapter supports. Use the maximum value
of 160 MBytes/sec. If a device is not Ultra160, select the transfer rate of the
device (80, 53, 40, ...).
14
Chapter 2 Configuration with SCSISelect
· Initiate Wide Negotiation—(Default: Yes) When set to Yes, the SCSI host bus
adapter attempts 16-bit data transfer (wide negotiation). When set to No, the
SCSI host bus adapter uses 8-bit data transfer unless the SCSI device requests
wide negotiation.
NOTE Set Initiate Wide Negotiation to No if you are using an 8-bit
SCSI device that hangs or exhibits other performance
problems with 16-bit data transfer rate enabled.
· Enable Disconnection—(Default: Yes) When set to Yes, allows the SCSI
device to disconnect from the SCSI bus. Leave the setting at Yes if two or more
SCSI devices are connected to the SCSI host bus adapter. If only one SCSI
device is connected, changing the setting to No results in slightly better
performance.
· Send Start Unit Command—(Default: Yes) When set to Yes, the Start Unit
Command is sent to the SCSI device at bootup.
The following three options have no effect when the SCSI host bus adapter BIOS is
disabled. (The SCSI host bus adapter BIOS is normally enabled by default.)
· Enable Write Back Cache—(Default: N/C) Can be used to enable or disable
the write-back cache on SCSI disk drives connected to the host adapter. Leave
this option at its default setting of N/C (no change), which usually allows for
optimum drive performance.
· BIOS Multiple LUN Support—(Default: No) Leave this setting at No if the
device does not have multiple Logical Unit Numbers (LUNs). When set to Yes,
the SCSI host bus adapter BIOS provides boot support for a SCSI device with
multiple LUNs (for example, a CD “juke box” device in which multiple CDs can
be accessed simultaneously).
· Include in BIOS Scan—(Default: Yes) When set to Yes, the SCSI host bus
adapter BIOS includes the device as part of its BIOS scan at bootup.
15
Chapter 2 Configuration with SCSISelect
Advanced Configuration Options
NOTE Do not change the Advanced Configuration Options unless
absolutely necessary.
· Reset SCSI Bus at IC Initialization—(Default: Enabled) When set to Enabled,
the SCSI host bus adapter generates a SCSI bus reset during its power-on
initialization and after a hard reset.
· Display <Ctrl> <A> Messages during BIOS Initialization—(Default:
Enabled) When set to Enabled, the SCSI host bus adapter BIOS displays the

message on your screen during system bootup. If this setting is disabled, you can
still invoke the SCSISelect Utility by pressing <Ctrl> <A> after the SCSI host
bus adapter BIOS banner appears.
· Extended BIOS Translation for DOS Drives > 1 GByte—(Default: Enabled)
When set to Enabled, provides an extended translation scheme for SCSI hard
disks with capacities greater than 1 GByte. This setting is necessary only for
MS-DOS 5.0 or above; it is not required for other operating systems, such as
NetWare or UNIX.
16
CAUTION Changing the translation scheme destroys all data on the drive.
Be sure to back up the data before changing the translation
scheme.
Use the MS-DOS Fdisk command to partition a disk larger than 1 GByte controlled
by the SCSI host bus adapter BIOS, when using DOS, Windows 3.1.x, or Windows
95/98.
· Verbose/Silent Mode—(Default: Verbose) When set Verbose, the SCSI host
bus adapter BIOS displays the host adapter model on the screen during system
bootup. When set to Silent, the message will not be displayed during bootup.
· Host Adapter BIOS (Configuration Utility Reserves BIOS Space)—
(Default: Enabled) Enables or disables the SCSI host bus adapter BIOS.
o Leave at Enabled to allow the SCSI host bus adapter BIOS to scan and
initialize all SCSI devices.
Chapter 2 Configuration with SCSISelect
oSet to Disabled: Not scan if the devices on the SCSI bus (for
example, CD-ROM drives) are controlled by software drivers and do not
need the BIOS, and you do not want the BIOS to scan the SCSI bus.
o Set to Disabled: Scan Bus if you do not need the BIOS, but you want it to
scan the SCSI devices on the bus.
The following four options have no effect when the SCSI host bus adapter BIOS is
disabled. (The SCSI host bus adapter BIOS is normally enabled by default.)
· Domain Validation—(Default: Enabled) Determines the kinds of SCSI devices
connected and reduces data transfer speed when legacy SCSI devices are
detected. Displays the resulting data transfer rate.
· Support Removable Disks Under BIOS as Fixed Disks—(Default: Disabled)
Determines which removable-media drives are supported by the SCSI host bus
adapter BIOS. Choices are as follows:
o Disabled— No removable-media drives are treated as hard disk drives.
Software drivers are required because the drives are not controlled by the
BIOS.
CAUTION You may lose data if you remove a removable-media cartridge
from a SCSI drive controlled by the SCSI host bus adapter
BIOS while the drive is on. If you want to be able to remove
the media while the drive is on, install the removable-media
software driver and set Support Removable Disks Under
BIOS as Fixed Disks to Disabled.
o Boot Only—Only the removable-media drive designated as the boot device
is treated as a hard disk drive.
o All Disks—All removable-media drives supported by the BIOS are treated
as hard disk drives.
· BIOS Support for Bootable CD-ROMs—(Default: Enabled) When set to
Enabled, the SCSI host bus adapter BIOS allows the computer to boot from a
CD-ROM drive.
· BIOS Support for Int 13 Extensions—(Default: Enabled) When set to
Enabled, the SCSI host bus adapter BIOS supports Int 13h extensions as
required by Plug-and-Play. The setting can be either enabled or disabled if your
system is not Plug-and-Play.

Chapter 2 Configuration with SCSISelect
Using SCSI Disk Utilities
To access the SCSI disk utilities, follow these steps:
1. Select the SCSI Disk Utilities option from the menu that appears after starting
SCSISelect. SCSISelect scans the SCSI bus (to determine the devices installed)
and displays a list of all SCSI IDs and the devices assigned to each ID.
2. Use the arrow keys to move the cursor to a specific ID and device, then press
Enter.
3. A small menu appears, displaying the options Format Disk and Verify Disk
Media.
o Format Disk—Allows you to perform a low-level format on a hard disk
drive. Most SCSI disk devices are preformatted at the factory and do not need
to be formatted again.
CAUTION A low-level format destroys all data on the drive. Be sure to
back up your data before performing this operation. You
cannot abort a low-level format once it has started.
o Verify Disk Media—Allows you to scan the media of a hard disk drive for
defects. If the utility finds bad blocks on the media, it prompts you to reassign
them; if you select yes, those blocks are no longer used. Pressing Esc at any
time aborts the utility.

3 Microsoft Windows NT Installation
This chapter explains how to install the HP Ultra3 Family Manager Set driver <File
Name>adpu160m.sys for Windows NT.
If you are performing a first time Windows NT installation, see “Installing the
Driver When Windows NT is Already Installed” in the next section. If Windows NT
is already installed in your system, see “Installing the Driver When Windows NT is
Already Installed” on page 20.
Installing the Driver When Installing
Windows NT
The <File Name>adpu160m.sys driver is not embedded on the Windows NT 4.0
installation disks (or CD-ROM) and must be added during Windows NT installation.
Completing a Fresh Windows NT 4.0 Installation From Floppy
Disk
1. Start your system with the Windows NT Boot Disk in the floppy disk drive.
2. When prompted, insert disk #2 in your floppy disk drive. After a few moments
you will see a blue screen. To set up Windows NT now, press Enter.
3. Press S to skip auto-detection of your SCSI host adapter.
4. Press S again to specify an additional device.
5. Press Enter to select Others; insert the HP Ultra3 Family Manager Set disk for
Windows NT into your floppy disk drive.
6. Using the arrow keys, select the following driver and press Enter:
Adaptec Ultra3 PCI SCSI Controller (NT4.0)
7. To add other host adapters, press S and repeat from Step 5 for each additional
