Warning: Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to operate the
equipment.

This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

• Consult the dealer or an experienced radio TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference,
and (2) this device must accept any interference received, including interference
that may cause undesired operation.

NOTE: If the SX4055F Fibre Channel Expansion Module is used, the DPT
controller will not meet Class B limits. A DPT controller with an SX4055F module
does comply with the limits for a Class A digital device.

VCCI Statement

This is a Class B product based on the standard of the Voluntary Control

Preventing Electrostatic Discharge

CAUTION

Electrostatic discharge (ESD) can damage electronic
components and equipment. ESD occurs when electronic
components are improperly handled and can result in
complete or intermittent failures. Always follow ESD­prevention procedures when removing and replacing
components.

Use the following guidelines to prevent ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes skin

contact.

• Connect the equipment end of the strap to an unpainted metal chassis

surface.

• If no wrist strap is available, ground yourself by touching the metal

chassis.

• When installing a component, use any available ejector levers or

captive installation screws to properly seat the bus connectors in the
backplane or card slot. These devices prevent accidental removal,
provide proper grounding for the system, and help to ensure that bus
connectors are properly seated.

• When removing a component, use any available ejector levers or

captive installation screws to release the bus connectors from the
backplane or card slot.

• Handle adapter cards by available handles or edges only. Avoid

touching the printed circuit boards or connectors.

• Place a removed component board-side-up on an antistatic surface or

in an approved antistatic container.

• If you plan to return the component to DPT, immediately place it in a

static shielding container.

• Avoid contact between printed circuit boards and clothing. The wrist

strap only protects components from ESD voltages on the body; ESD
voltages on clothing can still cause damage.

About Your New SmartRAID V Controller

You can use an SX405x Bus Expansion Module to expand a Millennium
controller with one or two additional SCSI channels or with one Fibre
Channel Arbitrated Loop (FC-AL) port. Millennium Fibre Channel
controllers can be expanded with one additional FC-AL port. By using an
SX4055F Bus Expansion Module, Fibre Channel and SCSI buses can
coexist on the same SCSI controller (PM375xU2 models only). SX405x Bus
Expansion Modules are daughter cards that attach to the SmartRAID V
controller and do not require an additional card slot in the host system.

The PM3755U2B controller can be upgraded to include a battery-backed
cache by adding a BB4050 battery module.

• For controlling DPT RAIDstation storage cabinets or other
manufacturers’ cabinets, Millennium SCSI controllers provide a
Very High Density Cable Interconnect (VHDCI) 0.8 mm external
connector.

• To simultaneously control SCSI devices mounted in the host system,
Millennium SCSI controllers provide an internal, high-density 68-pin
connector.

• The Millennium Fibre Channel controller provides a single High
Speed Serial Data Connector (HSSDC) for external connections. Dual
loop redundancy is available by adding an SX4055F Expansion Module.

The memory sockets on a Millennium controller accept up to 256MB of
cache for maximum performance. For maximum data protection, use the
DPT ECC SIMMs or DIMMs listed below:

Model Description

SM4050-16 16 MB ECC SIMM

SM4050-64 64 MB ECC SIMM
DM4050-16 16 MB ECC DIMM
DM4050-64 64 MB ECC DIMM
DM4060-16 16 MB ECC DIMM
DM4060-64 64 MB ECC DIMM

NOTE The PM3755U2B controller only accepts DM4050 or DM4060

modules. Do not use non-DPT DIMMs for this controller.

The PM3754U2 controller can use either standard 32- or 36-bit1 single­sided, low-profile 60ns (or faster) EDO SIMMs. However, standard EDO
SIMMs do not provide ECC data protection. The PM3754U2 data cache is
protected by ECC only when DPT SM4050 memory modules are installed.
The green ECC Enabled LED is lit when DPT memory is installed. Refer
to Appendix A, “Assembly Drawings” for the location of this LED.

RA4050 RAID Accelerator Features

The RA4050 RAID Accelerator module adds up to 64 MB of cache
hardware RAID 5 and 0+5 to a Century controller or additional cache and
hardware XOR to a Decade controller. The RA4050 connects to the end of
the controller and does not require an additional slot in the host system.

The RA4050 hardware cache can provide a substantial performance
improvement in systems with heavy disk I/O load, such as CAD
workstations, and in network servers running operating systems such as
Windows NT, Novell NetWare or UNIX.

The RA4050 supports up to 64 MB of cache using four SIMM sockets. Each
socket accepts either a 16MB or 64MB standard 32- or 36-bit2 single-sided,
low-profile 60ns (or faster) EDO SIMM, or one of the DPT ECC SIMMs
listed below:

Model Description

SM4050-16 16 MB ECC SIMM
SM4050-64 64 MB ECC SIMM

DPT SM4050 SIMMs are recommended for systems where data integrity
is critical. Although, standard EDO memory modules can be used to
provide RAM for the cache, SM4050 SIMMs protect the cache with ECC
capability. The green ECC Enabled LED is lit when DPT memory is

About Your New SmartRAID V Controller

SmartRAID V Controller LEDs

SmartRAID V controllers provide nine LEDs that let you visually monitor
controller activity. Several different controller states are indicated by the
LED as outlined in the following sections. Two additional LEDs indicate
the status of the cache memory on the controller. See Appendix A,
“Assembly Drawings” for the location of the LEDs on your controller.

LED Display During Power-Up

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.

Fast Idle The controller enters a fast idle pattern while

waiting for the I2O initialization commands after
the address translation unit (ATU) and PCI bridge
have been enabled.

NOTE The ATU, PCI bridge and cache module (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.

LED Display During Controller Idle

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.

2-12

About Your New SmartRAID V Controller

LED Display During Controller Active

When the power-up sequence is complete, viewing the LEDs can help you
determine the operating status of the controller. These LED patterns are
also useful for troubleshooting. Refer to Appendix B, “Troubleshooting” for
more information on interpreting LED patterns.

LED Function

1 Heartbeat. Indicates that controller interrupts are enabled and

that the controller is alive. During controller activity, this LED
flashes four times a second.

2 Indicates the occurrence of a non-maskable interrupt (NMI) to the

I/O processor on the controller.

3 Indicates the controller’s internal operating system is in its idle

loop.

4 Indicates that the controller’s internal operating system is

processing an interrupt.
5 Reserved for future use.
6 Indicates that the cache controller is using DMA to perform a data

transfer.
7 Indicates the controller is generating parity information for a RAID

5 array (hardware XOR).
8 Indicates that there is a command on the SCSI or Fibre bus.
IRQ Lit only when the controller activates an interrupt on the host PCI

bus.

Cache Status LEDs

Two LEDs on the SmartRAID V controller indicate the status of the
onboard cache RAM. Refer to Appendix A, “Assembly Drawings” for the
location of the LEDs on your controller.

• The green ECC Enabled LED is lit when all installed SIMMs or DIMMs

are DPT ECC memory modules. This indicates that the controller data
cache is ECC protected.

• The red ECC Error LED, is lit when a correctable or non-correctable

error has been detected in one of the ECC SIMMs or DIMMs. The
LED will stay lit, even after the error has been corrected, until the
controller is powered-down. Cache failure information is recorded in
the controller error log and can be viewed using the Event Log
window in Storage Manager.

plug the appropriate modules onto the controller.

NOTE SmartRAID V Millennium controllers or Century and Decade

controllers with an RA4050 module must have cache installed.
DPT recommends that SmartRAID V controllers have at least

16MB of cache installed.

4. Install the controller and storage devices in the appropriate
enclosures. Attach all cables between the controller and the storage
devices.

5. Run Storage Manager on ROM (SMOR) by pressing Ctrl+D during
system boot to configure the controller’s SCSI termination and
verify proper hardware configuration. You can also use SMOR to
configure your storage subsystem and disk arrays. (Refer to
Chapter 4, “Storage Manager on ROM”.)

6. If you are setting up the computer system for the first time, install
the operating system on one of the controller’s disk drives or
arrays. During this process, you should also install any driver
updates for your DPT controller. Refer to Chapter 5, “Software
Installation” for specific instructions.

7. Install any required operating system drivers and Storage
Manager. Refer to Chapter 5, “Software Installation” for additional
information.

Storage Manager for Microsoft Windows is on the DPT Windows
NT, Windows 95/98 diskette. Storage Manager for SCO UNIX (Motif
version) is on the SCO UNIX diskette.

Adapter Configuration and Installation

Configuration

DPT Fibre Channel controllers and attached Fibre Channel devices are
plug-and-play and will configure themselves automatically during boot.

SCSI devices in the system must be configured prior to use. This
configuration includes enabling SCSI termination for the devices and
setting the SCSI IDs for each device.

Narrow and Wide SCSI

The SCSI devices you will be installing can be either Narrow (8-bit) or
Wide (16-bit) SCSI devices. Wide SCSI disk drives allow data to be
transferred at twice the rate of older 8-bit devices. However, some SCSI
devices such as tape and CD-ROM drives still use an 8-bit interface. This
is not a problem because the Wide SCSI bus is backward compatible with
Narrow SCSI devices, allowing both types of SCSI devices to be used on
the same controller.

NOTE You can mix Narrow and Wide devices on a single 16-bit SCSI

cable. However, any Narrow devices must be attached to the
bus ahead of any Wide devices. This ensures that the 16-bit
signals are correctly terminated.

Configuring Cables

SmartRAID V SCSI controllers contain a single Wide SCSI bus with one
internal and one external SCSI connector. Each SmartRAID V SCSI
controller kit contains a Wide, 68-conductor SCSI cable. This cable is for
connections internal to the computer cabinet only.

SmartRAID V Fibre Channel controllers contain one Fibre Channel port
with a single Fibre Channel connector. The SmartRAID V Fibre Channel
controller requires a High Speed Serial Data Connector (HSSDC) cable. If
you do not have an HSSDC cable, this cable is available from DPT or a
cable supplier of your choice.

NOTE Internal and external, Narrow and Wide SCSI cables, Fibre

Channel cables, connector adapters and terminators can be
purchased directly from DPT (you can use our online web
store at www.dpt.com) or from a supplier of your choice.

3-4

Adapter Configuration and Installation

Configuring SCSI Termination

The devices on each physical end of a SCSI cable 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.

NOTE The SCSI cable supplied with your DPT controller has a

factory-installed active terminator on the end of the cable.
If you are using multiple SCSI busses on a single controller,

each separate bus must be terminated.

SCSI termination for SmartRAID V controllers is configured through the
SMOR utility or from the Configure Host Bus Adapter window in Storage
Manager. The controller has four possible termination settings:

Auto

The default setting. This can be used for all
cabling conditions except where a Narrow (8-bit)
cable is attached to the controller. 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 Wide and
Narrow cables to be simultaneously attached to
the controller.

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.

Adapter Configuration and Installation

Configuring Device IDs

The SCSI specification allows up to 7 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 a controller). Up to 126 devices can be attached to a single
Fibre Channel loop.

SCSI

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. For more information on SCSI
IDs, see Chapter 7, “Theory of Operation.”

Set the SCSI ID of each SCSI device attached to the controller to a unique
ID number between 0 and 6. The SmartRAID V controller is set to ID 7 by
default (most SCSI controllers use ID 7.) Wide SCSI devices can also use
SCSI IDs 8 through 15. 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 SmartRAID controller ID can be changed to any ID 0 – 7
by using SMOR or from the Configure Host Bus Adapter window in
Storage Manager.

NOTE Changing the controller ID is not recommended. You should

leave the SmartRAID V controller at SCSI ID 7.

Fibre Channel

DPT Fibre Channel controllers and their attached Fibre Channel devices
are configured automatically during boot. Device IDs are assigned within
the range 0 – 126 and cannot be changed manually.

3-7

Adapter Configuration and Installation

Installation

NOTE SmartRAID V Millennium controllers and Century or Decade

controllers with an RA4050 module should have at least 16MB
of cache installed.

Several optional modules are available to upgrade the performance of
your SmartRAID V controller:

• RA4050 RAID Accelerator – adds RAID 5, hardware XOR and cache

memory capacity to the Decade and Century controllers.

• SX4054U2 Bus Expansion Module – adds SCSI channels to a

SmartRAID V Decade or Century controller.

• SX4055U2 Bus Expansion Module – adds SCSI channels to a 64-bit

SmartRAID V controller.

• SX4055F Bus Expansion Module – adds one Fibre Channel port to a

SmartRAID V controller.

• SM4050-16 (-64) ECC SIMM – adds 16 or 64 MB of cache memory to

SmartRAID V Millennium non-battery backup controllers or to
SmartRAID V controllers using the RA4050 RAID Accelerator.

• DM4050-16 (-64) or DM4060-16 (-64) ECC DIMM – adds 16 or 64 MB

of cache memory to SmartRAID V PM3755U2B controllers.

• BB4050 – adds battery-backed cache capability to a PM3755U2B

controller. The battery-backed cache must be DPT DM4050 or DM4060
memory modules. Non-DPT DIMMs are not compatible with the
BB4050.

3-8

Adapter Configuration and Installation

Installing the RA4050 RAID Accelerator

SmartRAID V Century controllers can be upgraded to support RAID 5,
0+5 and data caching by installing the RA4050 RAID Accelerator module.

A Decade (PM1554U2) controller has built-in RAID 5 and 0+5 support
without an RA4050 module. Adding an RA4050 module to a Decade
controller provides up to 64MB of cache and hardware XOR performance
for RAID 5 operation.

NOTE Century or Decade controllers with an RA4050 module must

have at least one memory module installed on the RA4050.

To install the RA4050 module:

1. Install the SIMMs in the SIMM sockets of the module. Refer to the
section, “Installing SIMMs” in this chapter.

2. Attach the RA4050 module to the controller as shown in the
diagram below. The plastic docking guides should lock into place.
To remove the module, squeeze the plastic docking guides together
and separate the module from the controller.

3. To confirm that the RA4050 and SIMMs have been properly
installed, start SMOR and select the controller. The Information
window should indicate the RA4050 is attached and display the
amount of cache memory.

Up to 15 devices may be attached to each SCSI bus. Up to 125 devices can
be attached to the SX4055F Fibre Channel Bus Expansion Module.

Additional information about Ultra2 SCSI and Fibre Channel can be found
in Chapter 7, “Theory of Operations.”

NOTE If the SX4054/SX4055 has been properly installed, it will be

listed by SMOR when the controller is selected. See Chapter 4,
“Storage Manger on ROM” for additional information.

3-10

Adapter Configuration and Installation

To install an SX4054/SX4055 module:

1. Remove the module mounting bracket from the end of the module.
Keep the bracket screws.

2. Attach the module to the controller, connecting P5 on the SX405x to
J7 on the controller. Refer to Appendix A, “Assembly Drawings” for

NOTE SX4055 modules have two connectors (J7 and J8) that must

align correctly when installing the expansion module on a
Millennium 64-bit controller.

3. Install the new module mounting bracket (with additional holes for
the added external connectors) and secure with the screws from
Step 1 above.

4. Install the card in an available PCI slot and attach the mounting
bracket to the slot opening in the host system.

3-11

Adapter Configuration and Installation

Installing SIMMs

SmartRAID V PM3754U2 and PM3755F Millennium controllers support up
to 256MB of cache using four onboard SIMM sockets. One to four memory
modules of the same type and capacity can be installed.

SmartRAID V Decade and Century controllers can use up to 64MB of
cache provided by the SIMM sockets on an RA4050 module. One to four
SIMMs of the same type and capacity can be installed.

IMPORTANT

All installed SIMMs must be the same type and capacity.

Do not mix SM4050 ECC SIMMs and non-DPT SIMMs.
Do not use DPT SmartCorrect SM4000 SIMMs.

NOTE PM1554U2 controllers have 4MB of onboard cache.

RA4050 maximum cache memory can be a single 64MB SIMM,
or four 16MB SIMMs. You can use less than 64MB of memory;
however, you must install at least one 16MB SIMM.

ECC protected cache requires DPT SM4050 SIMMs. The ECC
Enabled LED on the controller is lit when DPT SIMMs are
installed.

3-12

Adapter Configuration and Installation

To install SIMM modules:

1. Install the SIMMs in the sockets as shown starting with socket 1.
Refer to Appendix A, “Assembly Drawings” for socket locations. Be
sure the SIMM is fully seated and locked in the socket.

Although standard 32- or 36-bit 16MB or 64MB low-profile single­sided 60ns EDO SIMMs can be used, DPT recommends that you
use DPT SM4050-16 or -64 ECC SIMMs for maximum data integrity.

2. To confirm that the SIMMs have been properly installed, use SMOR
to view the amount of cache memory reported when the
SmartRAID V controller is selected.

3-13

Adapter Configuration and Installation

Installing DIMMs

IMPORTANT

All installed DIMMs must be the same type and capacity.

At least one DIMM must be installed.
Use only DPT DM4050 or DM4060 DIMMs.
Do not use DPT SmartCorrect DM4000 DIMMs.

The SmartRAID V Millennium model PM3755U2B has four onboard
DIMM sockets for cache memory. The green ECC Enabled LED on the
controller is lit when ECC-capable DIMMs are installed.

To install DIMM modules:

1. Install the DIMMs in the sockets as shown starting with socket 1.

Refer to Appendix A, “Assembly Drawings” for socket locations.

2. To confirm that the DIMMs are properly installed, start SMOR and

Adapter Configuration and Installation

Installing the BB4050 Battery Backup Module

The BB4050 Battery Backup Module is used only on a PM3755U2B
Millennium controller.

To install the BB4050 Module:

1. Before installing the BB4050 module, be sure the battery pack
electrical connector is plugged in the socket on the BB4050 board.

2. Align the Battery Backup Module and the Millennium controller as
shown in the illustration.

3. Install the three fasteners through the appropriate holes in the
Millennium controller and into the matching posts in the Battery
Module. Tighten the fasteners.

IMPORTANT

Do not overtighten the fasteners; it can damage the circuit board.

3-15

Adapter Configuration and Installation

Installing the Controller

1. Connect the computer’s disk activity LED cable to connector P6 on

the controller. See Appendix A, “Assembly Drawings” for the
location of this connector.

Pins 1 and 3 of P6 are connected to +5V 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.

2. If you are using the internal SCSI cable, connect this cable to the

controller.

3. Install 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 controller that has the
lowest BIOS ROM address (typically, the lowest numbered PCI slot)
will become the booting controller. Refer to the “Determining the
Booting Controller” section for more information.

4. Connect any external cables to the controller.

NOTE If you have disk drives attached to a SCSI controller with a

Symbios chipset, use SMOR to set the Bootable Devices option
to Disable.

3-16

Adapter Configuration and Installation

Determining the Booting Controller

The controller whose BIOS has the lowest address will take control over
the boot process and that controller will become the booting controller.
Therefore, in a system with multiple controllers, you must ensure that the
DPT I2O BIOS occupies the lowest address if you want the DPT controller
to be the booting controller.

• In systems with multiple DPT SmartRAID V controllers, the DPT

controller in the lowest PCI slot number will be assigned the lowest
BIOS address, and will be the booting controller.

• In systems with both SmartRAID IV and SmartRAID V controllers

BIOS addresses are assigned in a system dependent manner. In this
case, the booting controller can be determined by observing the
system messages during the boot process.

If your system contains multiple DPT controllers, you can confirm which
controller has been chosen as the booting controller by running SMOR.
This utility will display a list of all DPT controllers, starting with the
booting controller.

Controller IRQ and Address

During the host system boot process, the host system BIOS should
automatically configure the DPT I2O BIOS interrupt level (IRQ) and
memory location for all DPT PCI controllers in the system. If problems
occur, refer to Appendix B, “Troubleshooting” for additional help.

3-17

Adapter Configuration and Installation

NVRAM Reset

SmartRAID V controllers retain their setup parameters even when
powered off. These parameters are stored on the controller in an area of
nonvolatile memory (NVRAM). There is a possibility that, through
improper configuration, the controller can be put into a state where it
hangs the system during boot. If this happens, the parameters stored in
the NVRAM can be restored to their default settings by the following
procedure:

1. Turn off power to the system.

2. Place a shorting jumper across pins 1 and 2 of P4 on the controller.

Refer to Appendix A, “Assembly Drawings for the location of P4 on
your controller.

3. Power on the system and wait until LEDs 3, 5, 7 and 8 on the

controller begin flashing.

4. Turn off power to the system and remove the jumper.

5. Restart the host system. If the system restarts normally, the

controller can now be configured using SMOR or Storage Manager.

If the system fails to boot, refer to Appendix B, “Troubleshooting” for
additional information.

3-18

Adapter Configuration and Installation

Using Microsoft Cluster Server

The information presented in this section is intended to help you configure
SmartRAID V controllers and a storage subsystem for host systems that
use Microsoft Cluster Server (MSCS) to provide fault-tolerant network
server resources. For specific information about installing and configuring
MSCS support on your Windows NT server, refer to the Microsoft Cluster
Server Administrator’s Guide.

MSCS lets you create a server cluster, that is two servers sharing a
common storage subsystem. Both servers can provide resources to
clients. However, they cannot both provide the same resources. If one
server should fail, the other server can take over the resources of the
failed server. This is called failover. The MSCS software on both servers
manages the switchover if one server should experience a system failure.
The storage subsystem controller in each server must also be able to
respond to the switchover and transfer the responsibility for I/O requests
from the failed server to the remaining server.

Clients do not see the individual servers in a cluster. They are presented
with a virtual server that contains the specific resources they require.

MSCS provides the following advantages for network servers:

• Availability
MSCS automatically detects the failure of an application or server and

restarts its resources on the other server. Users will experience only a
brief interruption in service.

In some cases it might be necessary for users to log on again when the
standby server assumes control. Refer to the Microsoft Cluster Server
Administrator’s Guide for additional information.

• Manageability
MSCS lets administrators view the status of cluster resources and

move the server workload onto different servers within the cluster as
necessary. This allows an administrator to perform manual load
balancing or rolling updates on the servers without taking data
storage or applications offline.

3-19

Adapter Configuration and Installation

System Requirements

DPT SmartRAID V controllers include support for MSCS host
configurations. To use Microsoft Cluster Server with a SmartRAID V
controller you need to do the following:

• Use host systems that conform to the Microsoft Hardware
Compatibility List for MSCS.

• Install Windows NT Advanced Server Enterprise Edition 4.0 (with
Service Pack 5 or later) or Windows 2000 Advanced Server on both
server systems.

Windows NT Workstation 4.0 does not support MSCS.

• Install and configure Microsoft Cluster Server software on both host
systems.

• Connect the servers using a TCP/IP network. This connection is used
by MSCS software to monitor the server operation and detect failures.

A static IP address is required for each server in the cluster. You
cannot use DHCP address assignment with MSCS unless you use the
DHCP server to assign the static IP addresses for MSCS resources.
You can use WINS or DNS to provide computer name to IP address
conversion. Refer to the Microsoft Cluster Server Administrator’s
Guide for additional information.

• Create a server cluster with two host systems that have SmartRAID V
controllers that are connected to a common storage subsystem. The
shared storage must use the NTFS file system.

NOTE Only one server can control the storage subsystem under

MSCS. Any changes to the storage subsystem must be made
from the console for the server that currently owns the
subsystem.

Do not install the server operating system on the storage that
uses the shared SCSI bus.

• Enable Microsoft Cluster Server support on both SmartRAID V
controllers. See Chapter 4, “Storage Manager on ROM” for
information about activating SmartRAID V support for MSCS.

NOTE Because the storage subsystem and controllers are on a

common SCSI bus, both controllers must have a unique SCSI
ID. To ensure they receive the highest priority for SCSI bus
access, use SCSI ID 7 (the default) for one controller and SCSI
ID 6 for the other controller. You can use SMOR to change the
SCSI ID assigned to a controller.

3-20

Adapter Configuration and Installation

How SmartRAID V Works with MSCS

When MSCS is operating on a server cluster, the servers continuously
send a heartbeat to each other across the private network connection.
When a server does not receive this signal for a preset interval, it
automatically begins the failover process of providing the resources of the
failed server and takes control of the storage subsystem.

When the transfer is complete, the failed server remains offline until the
problem that caused the failure is corrected. When the failed server is
restored, MSCS can initiate a failback operation so that the second server
releases its control of the other server’s resources and the previously
failed server begins servicing client requests for its assigned resources.

A logical array that is deleted can continue to appear as available in a
Storage Manager remote session from the other server in the cluster or
from a remote client. The cluster servers must be restarted to ensure that
the deleted array does not continue to be reported as available.

NOTE Both SmartRAID V controllers must be connected to the shared

storage subsystem using special cables that include pass­through termination. These cables can be purchased from DPT.

Storage Manager on ROM

Storage Manager on ROM (SMOR) is a
BIOS-based setup utility that lets you
configure your DPT SmartRAID V controller
without starting an operating system and
using Storage Manager. You can also use
SMOR to perform basic array configuration.
SMOR makes the initial setup of your
SmartRAID V controller and RAID storage
easier and faster.

Run SMOR

Run SMOR by pressing Ctrl+D
during system boot.

Configure your Controller

Use SMOR to set the hardware
options on your controller. You can
view the configuration of the
storage subsystems, low-level
format disk drives, and configure
the DPT I2O BIOS on your
SmartRAID V controller.

Create Disk Arrays

Use SMOR to create disk arrays;
install your operating system and
your SmartRAID V system is ready
to use.

4-2

SMOR

Overview

To configure your hardware and create disk arrays when Storage
Manager is not available, run Storage Manager on ROM (SMOR) during
the system boot. This is especially useful for a new system where you need
to create disk arrays before you install the operating system.

After your storage subsystem is configured, install your operating system
according to the appropriate procedure in Chapter 5, “Software
Installation”. For access to all of the advanced features of your controller,
install the version of Storage Manager specific to your operating system.

Follow these steps to run SMOR and configure a new system:

1. Press Ctrl+D when the DPT BIOS message appears during boot to
start SMOR.

2. Inspect the hardware configuration as shown by SMOR.

a. Verify that all peripheral devices and controllers are shown. If any

devices are missing from the display, exit SMOR and check your
hardware connections.

b. View the Information window for each controller to verify that all

installed expansion and memory modules are shown. Note the
IRQ and Address displayed in the Configuration window. The IRQ
and Address values may be required during installation of your
operating system.

3. Create disk arrays (see Array Operations in this chapter). Array
Groups can be created or modified at any time after system
installation. However, if the boot device will be an array, that array
must be created before the operating system is installed.

4. Exit SMOR when you are finished with the configuration tasks.
Arrays that were created or modified start building at this time. For

large arrays, this process may take several hours. You can perform
other activities on the system while the build operation continues.

The array groups being built can be accessed while the build is in
progress. However, access time will be slower until the build is complete.

If you have exited SMOR and you want to monitor the progress of the build
operation, you can view the Array Group Information window for the array
in Storage Manger. See Chapter 6, “Storage Manager” for additional
information.

SMOR

Information/Configuration Windows

When you highlight an item within the Tree View, the corresponding
Information View is displayed.

DPT I2O BIOS Settings

The example above is the default Information View when SMOR starts.
The settings in this view affect the DPT I2O BIOS and all the DPT
controllers in your system. To view or change these settings, highlight
DPT Configuration in the tree.

Controller Parameter Default Optional Settings

Bootable Devices Normal Disable

Enable Bootable CD-ROMs Disabled Enabled

DOS/Windows 3.1 Cache Setting Write Through Write Back

Scan Delay 1 second 1, 10, 20, 30

seconds

Smart ROM Options:

EBDA Relocation Disabled Enabled

Enable Extended Int13 Enabled Disabled

4-10

SMOR

Bootable Devices

These settings let you modify the system boot process for host systems
with multiple peripheral controllers in cases where the DPT I2O BIOS
does not provide effective or appropriate default operation.

The default setting causes the system to follow the order described in the
Determining the Booting Controller section of Chapter 3. If you select
Disabled, DPT controllers are not used as boot devices.

If you select Enable Bootable CD-ROMs, the DPT controller attempts to
detect a bootable CD-ROM that uses the El-Torito format.

NOTE This option is disabled by default, because some bootable

CD-ROMs contain device-specific boot code that will not work
with DPT controllers.

DOS/Windows 3.1 Cache Setting

This parameter determines how the controller responds to Int13 write
commands under DOS, Windows 3.1 and certain operating system
installation programs. The default is Write Through to avoid problems that
can occur during operating system installation if Write Back caching is
enabled. After the operating system is installed, you can change to Write
Back caching for improved performance.

Change this setting back to Write Through during future operating system
installs or upgrades to avoid problems.

NOTE The cache setting has no effect on controller cache operation

under Windows NT, UNIX or NetWare.

Scan Delay

Some SCSI devices require a time interval between power on and SCSI
bus reset and scan or they do not respond correctly. If devices are not
displayed in the Tree View after power on, set the delay to a longer
interval.

EBDA Relocation

This setting determines the way that SmartRAID V controllers handle
Extended BIOS Data Area (EBDA) relocation. You can enable this feature
to help avoid conflicts with other adapter cards if the controller is installed
in a host system with other adapters that follow standard EBDA relocation
rules.

Enable Extended Int13

This setting enables extended logical block addressing (LBA) for disk
devices. Logical block addressing enables operating system access to
disks larger than 8.6GB. You should not change this setting.

* Fibre Channel IDs are display only. They cannot be changed.

Bus

Each peripheral bus on a controller is assigned a number starting at 0.

4-14

SMOR

SCSI ID

SmartRAID V controllers are configured by default at SCSI ID 7. This
value should not be changed unless required for special configurations.

NOTE Fibre Channel IDs can be 0 – 126. However, these IDs are

configured dynamically and cannot be changed using SMOR
or Storage Manager.

TERMPWR

By default SmartRAID V controllers supply termination power for other
SCSI devices through the TERMPWR line on the SCSI cable. If you want
to change this setting, refer to the TERMPWR section in Chapter 7,
“Theory of Operation” for more information.

Termination

This setting controls the SCSI termination for the controller and bus. The
default value (Auto) should not be changed, unless both internal and
external cables are attached to the controller or you are using an 8-bit
(Narrow) cable. Refer to the Configuring SCSI Termination section in
Chapter 3, “Configuration and Installation” for information on setting this
parameter.

NOTE Termination is not used for Fibre Channel controllers.

SCSI Xfer Rate

DPT controllers automatically negotiate with each SCSI device at power­up or reset to set the maximum SCSI transfer rate. This parameter limits
the SCSI transfer rate to the value selected. This setting should not be
changed except when you are troubleshooting SCSI bus errors.

NOTE If setting this parameter to 5MHz eliminates SCSI bus data

errors, this is usually an indication that the SCSI bus is too
long or that the bus is not terminated correctly.

PCI Xfer Rate
Mem Address
IRQ

These are display only fields for information purposes. The values in the
Mem Address and IRQ fields may be needed when you configure your
operating system.

Cluster Server Enable

This option enables or disables support for Microsoft Cluster Server
configurations using the selected controller. Do not enable this option
unless you are creating a cluster server configuration.

SMOR

Array and Array Group Information

SmartRAID V controllers implement RAID 0, 1 or 5 disk arrays in
hardware. RAID 0 arrays are composed of any combination of individual
drives. RAID 1 arrays are always composed of two drives. RAID 5 arrays
contain three or more drives.

After the arrays have been created, one or more arrays of the same RAID
level can be combined into a Parity Group (see the Creating a Parity
Group section). Arrays are striped into Parity Groups by the controller
firmware. All the drives in an array or Parity Group must be attached to
the same controller, and appear to the host as a single Logical Storage
Unit (LSU).

The Information window for any array may be viewed by highlighting that
array.

NOTE Arrays do not start building until a Set System Configuration

action has been performed.

The Array Information window displays general array information and
hardware configuration. It is divided into three parts: identification, SCSI
Capabilities and Status.

4-18

SMOR

Identification

The identification section displays a general description of the highlighted
array:

Description

The RAID level used for the array.

Revision

The firmware revision of the controller to which the
array is attached.

Address

The address of the array, in the form HBA n, Channel

n, ID n, LUN n. Arrays are always assigned the

lowest logical address of any device in the array. This

field displays as much information as is necessary to

unambiguously define the address of the array.

Capacity

The usable capacity of the array in megabytes. The
available capacity of an array depends on the RAID
level of that array.

Removable

As reported by the devices in the array.

Block Size

Displays the sector (block) size for the selected device
in bytes. For disk drives, this value should be 512. If
the value is not 512, use SMOR to perform a low-level

format and create 512 byte sectors.

Stripe Size

Displays the stripe size used to create the array.

SCSI Capabilities

This section displays the SCSI capabilities of the array, as reported to the
operating system. The capabilities reported depend on the devices that
were used to create the array.

Status

This field displays the current status of the array. A progress indicator (a
numeric percentage of completion) can also appear if the array is Building
or Rebuilding. See the following table for array status definitions.

4-19

SMOR

Building

The array is being built.

Created

The array or device is defined but not
initialized.

Dead

A write-back cache to the array command
failed. This is an unrecoverable failure.

Degraded

A single drive in the array has failed; array
performance is affected.

Impacted

A verification is being performed on the array;

I/O performance is affected.

Missing

A drive is physically missing or will not

respond to commands on the device bus.

Optimal

The array is fully functional.

Pending

The array has been created and the build is
queued on the controller, but is not yet
started.

Rebuilding

Data is being rebuilt onto a drive in the array.

Warning

This status indicates that a drive in a fault
tolerant array has failed and the next drive

failure will cause loss of the array.

Setting the Configuration

There are two configuration options on the File menu:
Read System Config Causes SMOR to rescan to detect any changes in

hardware configuration or status. Any changes
that have been made and not saved are lost. This
operation is run automatically when SMOR is
started.

Set System Config Causes SMOR to save changes that have been

made to the storage subsystem configuration in
the controller memory. If any array groups or
parity groups have been created or modified, this
operation causes the controller to initiate a build
operation on the new groups.

4-20

SMOR

Array Operations

You can use SMOR to create or manage disk arrays. The following
sections describe how to use SMOR to create arrays and parity groups,
delete arrays, assign hot spare drives, and rebuild an array.

Refer to the Chapter 7, “Theory of Operation” for a complete discussion of
RAID levels and disk arrays.

Creating an Array

To create an array:

1. Select RAID–Create.

2. When the RAID Type dialog appears, select the RAID level you
want to use. The Stripe size is selected automatically; however you
can select a different stripe size value by highlighting the field and
using the up and down arrow keys to change the stripe size.

NOTE Although you can change the stripe size, DPT recommends

using the default value. This value has been selected for
optimum performance based on the type of disk array you
want to create.

When you are ready to proceed, select OK.
The Eligible Devices list will appear. Devices on this screen can be

either individual disk drives or previously created array groups.
Array groups appear in the list when you select RAID 0 and eligible
array groups exist.

3. Select the devices you want to include in the array:

a. To add devices to the array, highlight the device and press the

Spacebar. A checkmark appears next to the device to indicate that
it has been selected.

You might need to scroll the display down to view all eligible
devices.

4-21

SMOR

b. To remove a previously selected device from the array, highlight

the device and press the Spacebar.

4. When you are finished selecting drives for the new array, select

Done.

5. If you are creating a RAID 1 array, the RAID-1 Build Option dialog

appears.

RAID 1 arrays are built by copying the existing data from one
device to the other. Select the direction for the copy, then select OK.

6. Select File–Set System Config to start the build process. The array

you have created will begin building at this time. If you have created
multiple arrays, they are built serially in the order they were
defined.

Alternatively, you can exit SMOR. You will be prompted to save the
configuration changes. If you choose to save the configuration and
have defined arrays, the build process will begin.

For large redundant arrays, the build process can take several hours to
complete. You can exit SMOR and perform other activities on the system
while the build continues. An array being built can be accessed during the
build process.

If you exit SMOR and you want to monitor the progress of the build
operation, you can use the Array Group Information window for the array
in Storage Manger. See Chapter 6, “Storage Manager” for additional
information.

4-22

SMOR

Creating a Parity Group

Creating a parity group (RAID 0+1 or 0+5) is similar to creating a normal
RAID 1 or RAID 5 array group. Do the following to create a RAID 0+1 or
RAID 0+5 parity group:

1. Create and build your array groups as described in the preceding
section (Creating an Array).

Do not initiate the build process on any arrays that you intend to
use in a parity group.

2. After your initial array groups are created, select RAID–Create
again.

3. Select RAID 0 for the RAID type and click on OK.

4. Select two or more arrays of the same type from the Eligible Devices
list and click on Done.

NOTE You cannot combine arrays that use different RAID levels.

5. Select File–Set System Config to begin the build process for the
parity group.

The Tree View will display the parity group LSU as:

(x,x,x,x) FW RAID-0

with the array groups that were striped together listed where disk drives
would normally be listed. Selecting an array group component will branch
to the disk drives for that array group. The LSU address will be the lowest
address of the array logical addresses that make up the parity group.

4-23

SMOR

Deleting an Array

To delete an array, follow the steps below:

1. In the left pane, highlight the array that you want to remove, then

select RAID–Delete.

2. You will be warned that all data will be lost. Choose Ye s or No.

The array configuration for the devices is not deleted until you
select File–Set System Configuration or exit SMOR and choose to
save your changes.

Hot Spares

Any disk drive not assigned to an array or in use by the operating system
can be designated as a Hot Spare. Hot Spares automatically replace failed
drives in RAID 1 or RAID 5 arrays and are not accessible by the operating
system for other use. A Hot Spare can protect drives of equal or lesser
capacity attached to any peripheral bus on the same controller.

To assign a drive as a Hot Spare:

1. Highlight the drive you want to use in the left pane.

2. Select Action–Make Hotspare.

Selecting Action–Remove Hotspare will cause the selected Hot Spare drive
to be reassigned as a normal disk drive which is accessible by the
operating system.

Refer to Hot Spares in Chapter 6, “Storage Manager” for additional
information.

4-24

SMOR

Rebuilding a Failed Array

If a drive in a RAID 1 or RAID 5 array fails and the drive is not protected
by a Hot Spare, use the following procedure to replace the failed drive.

1. Remove and replace the failed drive according the procedures in
your hardware documentation.

2. When the failed drive has been replaced, choose RAID–Rebuild
Array to start the rebuild process.

The status of the array will change to Rebuilding (view the Information
window for that array). When the rebuild is complete, the array status will
change to Optimal.

NOTE A DPT RAIDstation enclosure will automatically detect the

replacement of a failed drive and initiate a rebuild operation
as soon as the new drive is online.

Formatting a Drive

Formatting SCSI hard drives is not normally required. However, if you
have a drive that was previously formatted with a sector size other than
512 bytes you must change the format to 512-byte sectors before you can
use the drive with a SmartRAID V controller. You can use SMOR to start a
low-level format operation and create a 512 byte/sector format.

IMPORTANT

Do not remove power from the drive until the format operation is completed.
Doing so can cause some drives to be left in an indeterminate state that will
require return to the manufacturer for repair or replacement.

Low-level formatting large capacity drives can take considerable time. Do
the following to start a low-level format for a disk drive:

1. Highlight the drive to be formatted.

2. Select Action–Format Drive.

3. Select OK and confirm.
To determine if the format has completed, view the Information

window for that drive.

4-25

SMOR

Managing Controller Firmware

SMOR includes several features that let you upgrade, save and restore the
firmware on your SmartRAID V controller. These options are listed on the
Action menu when a controller is selected in the Tree View.

The Flash HBA feature lets you install the latest DPT controller firmware,
I2O BIOS and SMOR utility software. The Save Firmware feature lets you
save the current controller firmware, I2O BIOS and SMOR software along
with the NVRAM settings to a floppy disk. This disk can be used to restore
the controller or copy the firmware, I2O BIOS, SMOR and NVRAM to
another controller.

Upgrading Firmware

The SmartRAID V controller firmware, DPT I2O BIOS and SMOR utility
are contained in flash ROM and can be upgraded by using SMOR. Each
component must be upgraded as a separate operation.

• Firmware image upgrades are contained in a xxxxxxxx.FWI file,
where the 8-character file name consists of the 4-digit controller model
and a 4-digit release number.

• DPT I2O BIOS images are contained in a file named I2OBIOS.xxx
(where, xxx is the version number).

• SMOR updates are contained in a file named SMORyyyy.xxx. Where,
yyyy is the build number and the file extension (xxx) is the version
number.

• The default NVRAM settings are contained in the file DPTV1_0.NVR.

DPT periodically releases updated firmware, I2O BIOS and SMOR
software. You can obtain the latest files by contacting DPT Technical
Support or from our FTP site at ftp.dpt.com.

NOTE It is much easier to perform the following procedure if the

image files are placed in the root directory of a diskette.

4-26

SMOR

Do the following to upgrade controller NVRAM, firmware, I2O BIOS, or
SMOR utility:

1. Place the diskette containing the image files in the diskette drive of
the system where the controller is installed.

2. In the Tree View, select the controller that you want to update.

3. Select Action–Flash HBA. The source file browser will appear.

4. Select the diskette drive in the source file browser window and
press Enter to expand the drive listing.

5. Highlight the image file you want to use and select OK to update the
controller flash ROM.

After the controller reads the image, it will display the version
number of the component you selected.

Select Yes to confirm.

6. A progress indicator will appear showing the progress of the
different stages of the flash operation.

If the operation does not complete successfully, refer to the procedures for
recovering from an incomplete or failed flash ROM upgrade in Appendix
B, “Troubleshooting”.

4-27

SMOR

Saving Controller Firmware to a Disk Image

This feature provides you with a way to save the current ROM software
and NVRAM settings for your controller to a bootable diskette. The
resulting diskette is a bootable disk and contains a copy of the three
controller software components: firmware, I2O BIOS and SMOR. The
utility also saves the current and default NVRAM settings.

The diskette will contain the following files:

SMORbbbb.vvv

Where bbbb is the build number and vvv is the version.

I2OBIOS.vvv

Where vvv is the version.

ffffvvbb.FWI

Where ffff is the adapter firmware type (ffff can be "3754" or "2554"). vv
is the version and bb is the build.

CURRENT.NVR

The current NVRAM settings for this controller.

DEFAULT.NVR

or

vvvvvvvv.NVR

Default NVRAM settings. vvvvvvvv is the specific version of the default
NVRAM settings if previously named.

SMORSbbb.vvv

This file is used to guarantee that the diskette will boot if there is no
current SMOR image available on the controller. (Where bbb is the
build number and vvv is the version of the in-memory copy of SMOR.)
The build and version may or may not be identical to the SMOR image
copied from the flash memory of the controller.

4-28

SMOR

Creating a Firmware Disk Image

To create the firmware backup diskette:

1. Press Ctrl+D when the DPT I2O BIOS banner appears during
system startup to start SMOR.

2. Move the highlight to the controller that you want to backup.

3. Insert a blank, formatted diskette into the host diskette drive.

data is erased.

4. Press Alt+A to select the Action drop-down menu.

5. Select Save Firmware. Press Tab to highlight Ye s when prompted.
Press Enter to begin the flash update.

The operation starts immediately. SMOR displays a progress bar and
numerical percentage of completion. When the operation is complete you
can exit SMOR and start the system normally.

Restoring Firmware from a Disk Image

To use the firmware backup:

1. Insert the diskette with the backup images into your diskette drive.

2. Power on or restart your system. The system will boot from the
diskette and start SMOR automatically.

3. Highlight the controller that you want to update.

4. Press Alt+A to open the Action menu and select Flash HBA.

5. Highlight the diskette drive and press Enter. SMOR will display a
list of valid files on the diskette.

6. Highlight the software image you want to use and press Tab to

diskettes or is not available from the
DPT web site, contact the
manufacturer of your operating system
to obtain an I2O OSM for your system.

5-2

Software Installation

Windows NT 4.0

The DPT SmartRAID V driver for Windows NT 4.0 provides support for
both disk drives and other SCSI devices, such as CD-ROMs and scanners.

NOTES

• Windows NT must be updated with Service Pack 4 or later.

• If you choose the Microsoft I

2

O OSM in place of the DPT class or

miniport driver, you will not be able to use Storage Manager.

• The Windows NT 4.0 OSM is not compatible with Windows 2000. If

you have a SmartRAID V controller installed under Windows 2000,
use the DPT miniport driver instead of an OSM.

• If you are installing Windows NT from an IDE CD-ROM, press F6

as soon as the NT Detect screen appears during the installation
process. This will cause the installation program to prompt for
installation of a mass storage driver earlier in the install process
and ensure that the disk drives attached to the controller are
available when required.

• The DPT class driver is installed and enabled automatically. The

class driver provides enhanced performance and reduced CPU
utilization during disk accesses. This driver will load before the
Windows NT disk class driver and acquire all disks attached to
DPT controllers. If you want to use the DPT miniport driver, do the
following after you complete the initial installation:

Open the Control Panel.
Double click the Devices icon.
Disable the entry for DPT DISK.
Restart the system.

5-3

Software Installation

There are three driver installation scenarios for Windows NT 4.0:

• Installing the SmartRAID V controller into a new system, then

installing Windows NT 4.0

• Upgrading an existing Windows NT 4.0 system

• Adding a SmartRAID V controller into an existing Windows NT 4.0

system, to be used in addition to a currently installed SmartRAID IV
or SmartCache IV controller

Each of these cases requires a slightly different procedure. Be sure you
select the correct procedure and follow the procedure carefully. If you
need additional assistance, contact DPT Technical Support.

Installing a New System

This procedure describes how to install a SmartRAID V controller and
Windows NT 4.0 on a new system. If Windows NT is to coexist with another
operating system, that operating system must be installed before you
install Windows NT. During the Windows NT installation, you will need one
blank high-density diskette to create an Emergency Repair Diskette.

To install a SmartRAID V controller and Windows NT 4.0 into a new
computer system, follow the steps below:

1. Install the SmartRAID V controllers and storage devices according

to the instructions in Chapter 3, “Configuration and Installation”.

2. Boot your system and run SMOR to verify your configuration.

Create your disk arrays now. Each array will appear to the
operating system as a single logical drive.

3. Ensure that the Windows NT CD-ROM is in the CD-ROM drive.

Boot the system from the Windows NT setup diskette 1.

4. Insert the additional setup diskettes when prompted.

5. Press S to skip Setup’s mass storage detection. Press S to Specify

Additional Devices. Select Other, then insert the DPT diskette for
Windows NT.

6. Select DPT I2O SCSI Adapter Driver for NT 4.0 and greater.

7. Press Enter and continue with the installation as described in the

Windows NT documentation.

5-4

Software Installation

NOTE If a SmartRAID IV or SmartCache IV controller is installed,

Windows NT mass storage detection routines will load an
older DPT driver for that device from the Windows NT diskette
or CD-ROM. After Windows NT installation completes, update
the driver using the version contained on the DPT diskette
that was supplied with your SmartRAID IV or SmartCache IV
controller.

Windows 95/98

The DPT SmartRAID V driver for Windows 95/98 provides support for both
disk drives and other devices, such as CD-ROMs and scanners.

There are several driver installation scenarios under Windows 95/98:

• Installing the SmartRAID V controller into a new system, then

installing Windows 98

• Installing a SmartRAID V controller into a new system, then installing

Windows 95

• Upgrading an existing Windows 95 system to Windows 98

• Adding a SmartRAID V controller to an existing Windows 95/98 system

• Upgrading Windows 3.1 to Windows 95 and installing a

SmartRAID V controller

Each of these cases requires a slightly different procedure.

Installing Windows 98 (Full Install Version)

This section describes the steps to install Windows 98 (Full Installation
Version) on one disk drive or array group using a SmartRAID V host
controller. Ensure that your hard drives, arrays, CD-ROM drive, and any

SCO UNIX

A diskette for SCO UNIX 3.2V4.2 and SCO UNIX OpenServer 5 (3.2V5.x) is
included with your SmartRAID V controller. The DPT diskette for SCO
contains the drivers for both versions of SCO. A second diskette contains a
Motif version of DPT Storage Manager for each version of SCO UNIX.

NOTE When assigning numbers to controllers, SCO starts with zero.

Storage Manager numbers controllers starting with one.

Installing SCO UNIX 3.2V4.2 or OpenServer 5

This section describes the steps to install SCO UNIX 3.2V4.2 and up
(including ODT 3.x) and SCO UNIX 3.2V5.0.x (OpenServer 5) on a single
drive or array group. These SCO operating systems are configured to
support one SCSI hard drive or array group at ID 0, one tape drive at ID 2,
and one CD-ROM at ID 5. If these devices are to be installed at this time,
make sure that their IDs have been set accordingly.

To install SCO, follow the steps below:

1. If installing SCO UNIX 3.2V4.2 or ODT 3.0, boot the system with the
N1 diskette. Enter the following string at the boot prompt :

defbootstr link=dpti4

If installing SCO UNIX 3.2V5.0.x, boot the system with the Boot
Disk. Enter the following string at the boot prompt:

defbootstr ahslink=dpti5

For SCO UNIX 3.2V5.04 or later the command is:

defbootstr link=dpti5

2. When prompted for the SCO BTLD diskette (DPT volume), insert
the DPT BTLD diskette into the floppy drive.

3. Insert the N1 or Boot disk again when prompted.

4. If installing SCO 3.2V4.2 or ODT3.0, insert the N2 diskette when
prompted. During the Hardware Roster, the following line should
appear:

% adapter type=dpti ha=0 id=7 channel=0, PCI

If you are installing SCO UNIX 3.2V5.0.x., during the Hardware
Roster, the following line should appear:

% adapter type=dpti ha=0 id=7, PCI

5-15

Software Installation

5. Continue the installation according to the SCO documentation.

NOTE If you are installing from tape or CD-ROM, SCO UNIX 3.2V4.2

expects to find the tape at Controller 0, SCSI ID 2, LUN 0 and
the CD-ROM at Controller 0, SCSI ID 5, LUN 0.

SCO OpenServer 5 will locate the tape or CD-ROM at any
valid SCSI address.

Adding to an Existing SCO UNIX 3.2V4.2 or
OpenServer 5 System

When adding a DPT controller to an existing SCO UNIX configuration,
perform the following steps.

1. Install the DPT controller.

2. Boot SCO UNIX.

3. After SCO UNIX has booted, place the DPT SCO driver diskette in

the floppy drive.

4. Run the installpkg utility.

SCO UNIX will read the diskette and prompt you to enter the
package name to be installed. Enter dpti4 for SCO UNIX 3.2V4.2 or
ODT 3.0, and dpti5 for SCO OpenServer 5.

5. Rebuild the kernel after the package is installed. Shutdown and

reboot the system to install the new kernel and add devices on the
controller.

SCO UnixWare 7

1. Install the SmartRAID V controller as in Chapter 3, “Controller

Configuration and Installation”.

2. Obtain the latest I2O supplement for UnixWare 7 from SCO (it

should be PTF7067E or higher).

3. Copy or download the ptf file to the /tmp directory. Use the pkgadd

utility to install the I2O supplement by entering the command:

pkgadd –d /tmp/ptf7067e.s

4. Follow the on-screen prompts to install the SCO UnixWare I2O

supplement.

5. Shutdown and reboot the system.

5-16

Software Installation

NOTE When you reboot several WARNING messages may appear and

scroll off the screen quickly. These will not occur after
“diskadd” is run and can be ignored.

6. Use the diskadd utility to add drives or arrays that are attached to a
SmartRAID V controller.

Run the sdiconfig –l utility in a terminal window or non-GUI screen.
This will list all controllers recognized by the operating system and
any attached devices. Use this listing to determine the proper ID to
use for the diskadd utility.

The diskadd command to add devices on a secondary controller is:

diskadd cCbBtTd

D

Where:

C specifies the ID for the controller in the system.
B is the controller bus number (from 0 – 7) to which the disks are

attached.

T is the target controller number (ID). The value of T can be

0 – 31.

D is the Logical Unit Number (LUN) of the disk device, from

0 – 31.

See the diskadd(1M) man page for more information.
For example, if a new drive or array is on the DPT controller, on channel 0,

with an ID of 0, the command would be:

diskadd c1b0t0d0
