Using the Adaptec CD
The Adaptec SCSI RAID CD is a bootable media. You can use this CD
to configure disk arrays in a host system that does not yet have an
operating system installed. The CD-ROM drive must be attached to a
controller and host system that recognizes bootable CDs. Some systems
might require you to change the system BIOS configuration so that the
CD-ROM drive is used as a boot device.
When the CD is used as a boot source, an operating system is loaded
and then the Adaptec SCSI RAID installation utility starts. You will be
able to read the product documentation, install I2O drivers, run Storage
Manager, and create disks to use for driver installation when the
operating system being installed cannot use the CD-ROM as a source
for the files.

4
When the Adaptec SCSI RAID Family install utility appears, you have
the following choices:
■Create driver disks
This selection will display a dialog that lists the operating
systems for which disks can be created. This lets you create
disks for operating system driver installation procedures that
cannot read directly from the CD-ROM.
■Launch RAID configuration utility
This selection starts the Storage Manager application so that
you can configure your RAID subsystem and build disk
arrays.
■View documentation
This selection displays a list of the available product manuals
and the read.me file with the latest release notes. Select a
document name and click on OK to view the information.
■Start a command shell
This selection starts a Linux command shell. This lets you
mount additional device or enter other system commands
that might be required during the installation.

5
■Reboot
This selection will restart the computer system. As soon as the
system begins to restart, remove the CD from the CD-ROM
drive if you do not want to use it for the boot device.
If you are using a Microsoft Windows operating system, put the CD
into your CD-ROM drive. If you have Autorun turned on, the Adaptec
setup utility will automatically start and display the Adaptec
installation menu with four options:
■Install Adaptec Storage Manager Pro

Installing and Configuring Hardware
Installation Overview
The process of installing an Adaptec controller consists of the following
steps:
1If you are using a RAIDstation enclosure, configure it as described
in the Adaptec RAIDstation User’s Manual.
2Configure device IDs, cables and termination for SCSI devices in
the host system.
3If you are expanding your cache memory, plug the appropriate
modules into the controller.

10
Note: Adaptec SCSI RAID controllers must have at least one
32MB memory module installed.
4Install the controller and storage devices in the appropriate
enclosures. Attach all cables between the controller and the storage
devices.
5Run Storage Manager on ROM (SMOR) by pressing Ctrl+A during
system boot. SMOR lets you configure the controller and verify
proper hardware configuration. You can also use SMOR to
configure your storage subsystem and disk arrays before installing
the operating system.
6Install the I2O driver for your operating system. You can also install
Storage Manager Pro or Storage Manager on operating systems that
support these applications.
Storage Manager Pro and Storage Manager are included on the
Adaptec CD. If you are using a Microsoft Windows operating system,
they can be installed automatically by the Adaptec Autorun install
utility. A version of Storage Manager Pro for NetWare and versions of
Storage Manager for SCO UNIX and Linux are also included on the
installation CD-ROM. Refer to Installing Adaptec Storage Management
Software on page 32 for specific information.

11
Configuring SCSI Termination
The physical ends of each SCSI bus must be terminated. Depending
upon how you configure your system, you will either terminate two
SCSI devices, or the SCSI controller and one peripheral SCSI device or
the last connector on the cable. Ultra2 and Ultra160 devices typically do
not provide built-in termination.
Note: If you are using multiple SCSI busses on a single
controller, each separate bus must be terminated.
SCSI termination for SCSI RAID controllers is configured through the
SMOR utility or from the Configure Host Bus Adapter dialog in
Storage Manager. The controller has four possible termination settings.
These are listed in the following table.
Auto The default setting. This setting can be used for all cabling
conditions, except where two Narrow (8-bit) cables are
attached or both a Narrow and Wide cable are used. For this
case, use High Only.
Disabled Turns off controller termination unconditionally.
Enabled Turns on controller termination unconditionally.
High Only Terminates only the additional signals that are used on Wide
SCSI devices. This allows a Narrow cable or a Wide and
Narrow cable to be simultaneously attached to the controller.

12
High Only termination is available only for devices on Bus 0. Devices
on the second bus (Bus 1) must use 16-bit termination. By using a
68-pin to 50-pin SCSI cable adapter, an 8-bit SCSI device can be
attached to a Wide SCSI cable along with Wide SCSI devices. However,
the device at the end of the cable must be a Wide SCSI device so that all
SCSI signals are terminated. For internal and external cables where one
cable is an 8-bit (Narrow) SCSI cable, set the controller termination to
High Only.
The following illustration shows various SCSI cabling examples.
Terminate your SCSI devices as shown in the following examples,
ensuring that only the devices at the ends of the cables are terminated.

Configuring Device IDs
The SCSI specification allows up to seven SCSI devices (and a
controller) to be connected to a single 8-bit SCSI bus. A Wide SCSI bus
can support up to 15 devices and the controller.
All SCSI devices, including the controller, must be assigned a unique
SCSI ID. SCSI IDs, which are typically set using jumpers or switches on
peripheral devices, can be assigned any number from 0 to 7 for 8-bit
SCSI devices or 0 to 15 for Wide SCSI devices.
Set the SCSI ID of each SCSI device attached to the controller to a
unique ID number between 0 and 15 (0 – 6 for 8-bit devices).
SCSI RAID controllers are set to ID 7 by default. SCSI IDs can be
duplicated on the same controller if the devices using the same ID are
not attached to the same bus.
If necessary, the SCSI RAID controller ID can be changed to any ID: 0-7.
You can use SMOR or the Configure Host Bus Adapter dialog in
Storage Manager to change the controller SCSI ID.
Note: Changing the controller ID is not recommended. You
should leave the Adaptec controller at SCSI ID 7 unless your
configuration requires unique controller IDs.

15
Ultra2 and Ultra160 SCSI
SCSI RAID Ultra2 or Ultra160 SCSI buses support both LVD and
single-ended devices, which can be mixed on the SCSI bus. However,
connecting a single-ended device to an Ultra2 or Ultra160 bus forces
the entire bus to run in single-ended mode with a maximum speed of
20 MHz.
Do not connect older High Voltage Differential SCSI devices to a Low
Voltage Differential SCSI bus. They can damage the LVD hardware.
Installing the Controller
1Connect the computer’s disk activity LED cable to connector P6 on
the controller. See the appropriate SCSI RAID Installation Guide for
the location of this connector.
2Pins 1 and 3 of P6 are connected to +5 V and Pins 2 and 4 are
connected to GND. Ensure that the positive lead of the LED cable
(usually a red wire or marked with a red stripe) is attached to Pin 1
or 3 and the negative lead (usually a black wire) is attached to Pin 2
or 4.
3If you are using an internal SCSI cable, connect this cable to the
controller.
4Install the controller in an available 32- or 64-bit PCI bus slot and
secure the controller bracket to the host system cabinet with the
screw provided. In a system with multiple controllers, the

16
controller that has the lowest BIOS ROM address (typically, the
lowest numbered PCI slot) will become the booting controller.
5Connect any external cables to the controller.
Determining the Booting Controller
Adaptec SCSI RAID controllers are shipped with an Adaptec I2O BIOS
ROM enabled for PCI assignment. This ROM BIOS intercepts and
processes INT13 BIOS calls with an embedded DOS driver.
The Adaptec I2O BIOS ROM can be disabled or the address changed
automatically by the system’s Plug-and-Play BIOS. In systems with
multiple Adaptec controllers, the first Adaptec I2O controller found
during boot loads its BIOS and installs all of the Adaptec hardware on
the system. Any additional Adaptec I2O controllers that are found
automatically detect the presence of the first controller and disable
their BIOS code. The disk controller that has the lowest BIOS ROM
address (typically, the lowest PCI slot number) will become the booting
controller.
Ensure that the Adaptec ROM occupies the lowest address if you want
the Adaptec controller to be the booting controller in a system with
controllers from multiple manufacturers.
Some system BIOS manufacturers select the smallest add-in BIOS as
the first candidate, therefore slot selection has no effect on which
adapter BIOS loads first. In this case, you need to disable the BIOS on

17
selected adapters to control which adapter is the boot controller. This
procedure can also be helpful in situations where it is physically
difficult to manage the slot order.
If your system contains multiple Adaptec controllers, you can confirm
which controller has been chosen as the booting controller by running
SMOR. This utility will display a list of all Adaptec controllers, starting
with the booting controller.
Installing Memory Modules
Caution: Adaptec controllers with expandable cache
must have at least one memory module installed. If
more than one is installed, they must be the same type
and capacity.
Adaptec SCSI RAID controllers support up to 128 MB of cache using a
onboard DIMM sockets. Adaptec recommends that all SCSI RAID
controllers have at least 32 MB of cache installed. To confirm that the
memory modules are properly installed, start SMOR and select the
SCSI RAID controller to display the amount of cache memory reported.
Adaptec controllers will report 16 MB less cache than is actually
installed because the first 16 MB of memory is used for the onboard
processor. The total installed memory is reported correctly.
!

18
Note: ECC-protected cache is available only when using ECC
memory modules. The ECC-enabled LED on the controller is
lit when ECC memory is installed.
LED Indicators
All Adaptec controllers provide nine LEDs that let you visually
monitor controller activity. Two additional LEDs (ECC EN and ECC
ERR) indicate the status of the cache memory on the controller. For
additional information about LEDs on SCSI RAID controllers, see the
Installation Guide for your controller.
Power Up LED Status
During its power-up sequence, the controller passes through the
following states in sequence, as indicated by the LEDs:
■Memory Mapped I/O LEDs 6 and 7 and LEDs 5 and 8 flash
alternately while the controller waits for the host computer to
initialize the Address Translation Unit (ATU) on the PCI bus.
■Bridge LEDs 5 and 7 and LEDs 6 and 8 flash alternately while
the controller waits for the host computer to initialize its
PCI-to-PCI bridge.

19
■Fast Idle The controller enters a fast idle pattern while waiting
for the I2O initialization commands after the ATU and PCI
bridge have been enabled.
Note: The ATU, PCI bridge and cache modules (if installed)
must be configured and enabled before the I2O initialization
can be completed. If any one of these components are not
configured or become disabled during the Fast Idle phase, the
pattern will return to the respective wait pattern for the
affected component.
Controller Idle Indication
When no commands are in progress and all bus activity has ceased, the
controller enters the Idle state. This is indicated by a rotating pattern in
LEDs 1 through 8.
Bus Status LEDs
Adaptec 3000S series SCSI RAID controllers include status LEDs to
indicate the following SCSI bus operating conditions. Channel A
normally is referred to as Bus 0 and Channel B is normally referred to
as Bus 1.
