This chapter describes the LSI21002 PCI to Dual Channel SCSI Host

Adapter interfaces to PCI computer systems and includes these topics:

•

Section 1.1, “General Description,” page 1-1

Section 1.2, “Features,” page 1-2

Section 1.3, “Interface Descriptions,” page 1-4

1.1 General Description

The LSI21002 provides internal and external SCSI interfaces to PCI

computer systems that require BIOS support on the add-in SCSI adapter.

It will be referred to as the LSI21002 throughout this manual. Installing

the LSI21002 in your PCI system allows connection of SCSI devices over

a SCSI bus.

The dual channel LSI21002 provides 16-bit Low Voltage Differential

(LVD) and Single-Ended (SE) SCSI solutions for your computer, using

only one PCI slot. This board supports legacy Fast SCSI devices, Ultra

SCSI devices, and the newest Ultra2 SCSI devices.

Channel A supports only the SE mode. Channel B supports SE and LVD

modes of operation.

The Storage Device Management System (SDMS™) software operates

the board. The design of the board does not prevent other software from

being used with it.

This guide, along with the PCI Storage Device Management System

SDMS 4.0 User’s Guide, contains product information and installation

instructions to help you gain the full benefits of the LSI21002.

1.3 Interface Descriptions

This section provides a more detailed explanation about the PCI

Interface, the SCSI Interface, the SCSI Activity LED Interface, and Wide

Ultra2 SCSI.

1.3.1 The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O

components to a PC processor and memory subsystem. The PCI

functionality for the LSI21002 is contained within the LSI53C896 PCI

Dual Channel SCSI Multifunction Controller. The LSI53C896 connects

directly to the PCI bus and generates timing protocol in compliance with

the PCI specification.

The PCI interface operates as a 32-bit DMA bus master. The connection

is made through edge connector J1 (see Figure 2.1). The signal

definitions and pin numbers conform to the PCI Local Bus Specification

Revision 2.1 standard. The LSI21002 conforms to the PCI universal

signaling environment for a 5 V or 3.3 V PCI bus.

1.3.2 The SCSI Interface

The SCSI functionality for the LSI21002 is contained within the

LSI53C896 chip. The LSI53C896 connects directly to the two SCSI

buses for SE or LVD SCSI applications and generates timing and

protocol in compliance with the SCSI standard. One SCSI interface

operates at a burst transfer rate of up to 40 Mbytes/s for wide Ultra SCSI

transfers, and the other up to 80 Mbytes/s for wide Ultra2 SCSI transfers.

Channel A is SE only with active autosensing termination. The

Channel A interface is made through connectors J2, J3, and J4.

Connector J2 is a 68-pin high density latching right angle receptacle for

internal SCSI connections. Connector J3 is a 50-pin high density right

angle receptacle that protrudes throughout the ISA/EISA bracket.

Connector J4 is a 50-pin narrow (ribbon) internal connector.

Channel B may be either SE or LVD with active termination always

enabled. The Channel B interface is made through connector J5. J5 is a

68-pin high density latching right angle connector for internal SCSI

connections.

1-4

Using the LSI21002

See Figure 2.1 for the location of these connectors.

The LSI21002 supplies SCSI bus TERMPWR through a blocking diode

and self-resetting 1.5 A short circuit protection device. An on-board LED

lights up when TERMPWR is shorted and has turned off.

A 40 MHz oscillator is installed on the LSI21002 to provide the clock

frequency to the LSI53C896 that is necessary to support SCSI transfers.

1.3.3 SCSI Activity LED Interface

The LSI21002 LED interface is a four-wire arrangement that allows

connection of an LED harness to the board. The connector on the

LSI21002 is J6 for both channels. See Table A.7 in Appendix A for the

signal name and pin numbers for this LED interface.

1.3.4 Wide Ultra2 SCSI

The LSI21002 has full support for Wide Ultra2 SCSI. This interface is an

extension of the SCSI-3 family of standards that expands the bandwidth

of the SCSI bus to allow faster synchronous data transfers, up to

80 Mbytes/s. Wide Ultra2 SCSI provides a doubling of the data rate over

the Ultra SCSI interface, while it allows increased cable length and more

devices than Ultra SCSI interfaces.

Special SCSI cables are specified for operation with Wide Ultra and

Ultra2 SCSI devices, and you must consider the total number of devices

and the length of your SCSI bus when setting up your system. The

section on connecting your SCSI peripherals in Chapter 2, "Installing the

LSI21002," provides a more detailed explanation of SCSI bus

connections. See Table 1.1for maximum bus lengths in meters.

When you purchased the LSI21002 kit, the cable provided in the kit is

matched for a Fast/Ultra/Ultra2 SE or LVD operation. This cable also has

built-in LVD termination since most Ultra2 hard disk drives are not made

with on-board LVD termination.

1. This parameter may be exceeded in point-to-point and engineered

applications.

2. LVD was not defined in the original SCSI standards for this speed. If all

devices on the bus support LVD, then 12-meter operation is possible at this

speed. However, if any device on the bus is SE only, then the entire bus

switches to SE mode, and the distances in the SE column apply.

3. SE and high power differential are not defined at Ultra2 speeds.

Using the LSI21002

Chapter 2

Installing the LSI21002

This chapter describes installing the LSI21002 into PCI computer

systems and includes these topics:

•

Section 2.1, “Quick Installation Procedure,” page 2-1

Section 2.2, “Detailed Installation Procedure,” page 2-3

Section 2.3, “Setting Interrupts (Exceptional Cases),” page 2-24

Section 2.4, “Completing the Installation,” page 2-25

2.1 Quick Installation Procedure

This section provides quick setup instructions for the experienced

computer user with prior host adapter installation and SCSI bus setup

experience. If you prefer more detailed guidance for installing the

LSI21002, please follow the instructions in Section 2.2, “Detailed

Installation Procedure.”

For safe and proper installation, check the user’s manual that was

supplied with your computer and perform the following steps.

Step 1. Before proceeding, ground yourself so that a static discharge

does not damage the board. Remove the LSI21002 from the

packing and check that it is not damaged. An example of this

host adapter board is shown in Figure 2.1.

Step 2. Switch off and unplug the system.

Step 3. Remove the cabinet cover on your computer to access the PCI

slots.

Caution.

Ground yourself by touching a metal surface before

handling boards. Static charges on your body can damage

electronic components. Handle plug-in boards by the edge;

LSI21002 PCI to Dual Channel SCSI Host Adapter

2-1

do not touch board components or gold connector contacts.

The use of a static ground strap is recommended.

Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit

slot should be used. The LSI21002 will work in a 64-bit slot, but

only 32 bits are used. The LSI21002 requires a PCI slot that

allows bus master operation. See Figure 2.2.

Step 5. Remove the blank panel on the back of the computer aligned

with the PCI slot that you intend to use. Save the bracket screw.

Step 6. Carefully insert edge connector J1 of the host adapter into the

PCI slot. Make sure the edge connector is properly engaged

before pressing the board into place. See the example shown

in Figure 2.2.

Note.

You may notice that the components on the PCI host

adapter face the opposite way from those on other non-PCI

plug-in boards you have in your system. This is correct, and

the board is keyed to go in only one way.

Step 7. The bracket around connector J3 should fit where the blank

panel was removed. Secure it with the bracket screw before

making the internal and external SCSI bus connections (see

Figure 2.2).

Step 8. If you are connecting any internal SCSI devices, plug a 68-pin

connector on the end of the internal SCSI ribbon cable into

connector J2 or J5, or plug a 50-pin connector into J4 for an

8-bit SCSI (see Figure 2.1). Make certain to match pin 1 on all

connectors.

Note.

It is possible to use both internal connectors if no external

devices are attached to the host adapter. You may use only

two of the three connectors at once.

Step 9. Connect your computer’s LED cable if desired. This LED cable

drives the front panel LED found on most PC cabinets to

indicate activity on the SCSI bus. See Table A.7 in Appendix A

for the signal name and pin numbers for this LED interface.

Step 10. Replace the cabinet cover as described in the user’s manual for

your computer.

Step 11. Make all external SCSI bus connections.

2-2

Installing the LSI21002

Remember: The SCSI bus requires proper termination and no duplicate

SCSI IDs.

Step 12. Refer to the PCI Storage Device Management System SDMS

4.0 User’s Guide (or the guide for the software that you will use)

to load the driver software for your particular operating system.

2.2 Detailed Installation Procedure

This section provides step-by-step instructions for installing your

LSI21002 and connecting it to your SCSI peripherals. If you are

experienced in these tasks, you may prefer to use Section 2.1, “Quick

Installation Procedure.” If you are not confident that you can perform the

tasks as described here, LSI Logic suggests getting assistance.

Detailed Installation Procedure

2-3

2.2.2 Inserting the Host Adapter

For safe and proper installation, check the user’s manual supplied with

your computer and perform the following steps:

Step 1. Before proceeding, ground yourself so that a static discharge

does not damage the board. Remove the LSI21002 from the

packing and check that it is not damaged. An example of this

host adapter board is shown in Figure 2.1.

Step 2. Switch off and unplug power cords for all components in your

system.

Step 3. Remove the cabinet cover on your computer to access the PCI

slots.

Caution:

Ground yourself by touching a metal surface before

removing the cabinet cover. Static charges on your body

can damage electronic components. Handle plug-in boards

by the edge; do not touch board components or gold

connector contacts. The use of a static ground strap is

recommended.

Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit

slot should be used. The LSI21002 will work in a 64-bit slot, but

only 32 bits are used. The LSI21002 requires a PCI slot that

allows bus master operation. See Figure 2.2.

Step 5. Remove the blank panel on the back of the computer aligned

with the PCI slot that you intend to use. Save the bracket screw.

Step 6. Carefully insert edge connector J1 (see Figure 2.1) of the host

adapter into the PCI slot. Make sure the edge connector is

properly engaged before pressing the board into place as

shown in Figure 2.2.

Step 7. You may notice that the components on the PCI host adapter

face the opposite way from those on other non-PCI adapter

boards you have in your system. This is correct, and the board

is keyed to go in only one way.

2-4

Installing the LSI21002

Step 8. The bracket around connector J3 (see Figure 2.1) should fit

where you removed the blank panel. Secure it with the bracket

screw (see Figure 2.2) before making the internal and external

SCSI bus connections.

2.2.3 Connecting the SCSI Peripherals

All internal SCSI bus connections to the LSI21002 are made with an

unshielded, 68- or 50-conductor ribbon cable (see Figure 2.3). One side

of this cable is marked with a color to indicate the pin-1 side. The

connectors on this cable are keyed to ensure a proper pin-1 connection.

Use Ultra/Ultra2 rated cables for these bus speeds. (See Table 1.1 in

Chapter 1.)

2-6

Installing the LSI21002

For convenience, Channel A also has a 50-pin narrow (ribbon) connector.

Some internal cables come with an SE/LVD terminator on one end. This

end should be furthest from the host adapter.

All external SCSI bus connections to the LSI21002 are made with a

shielded, 50-pin high density cable (see Figure 2.3). The connectors on

this cable are always keyed to ensure a proper pin-1 connection.

2.2.3.1 Making Internal SCSI Bus Connections

This section provides step-by-step instructions about making internal

SCSI bus connections:

Step 1. To connect an internal SCSI device, plug the 68-pin connector

end of a wide internal SCSI ribbon cable into connector J2 or

J5. See the example in Figure 2.4.

Step 2. Plug the 68-pin connector on the other end of the wide internal

SCSI ribbon cable into the SCSI connector on the internal SCSI

device. Pin 1 must match on all connections. An example of this

connection appears in Figure 2.5.

Figure 2.5 Internal SCSI Ribbon Cable to Internal SCSI Device

Step 3. To plug in additional internal SCSI devices, use an internal

SCSI ribbon cable with the required number of connectors

attached along its length. See the example in Figure 2.6.

Figure 2.6 Connecting Additional Internal SCSI Devices

2-10

Installing the LSI21002

An example of multiple internal SCSI devices chained together is

shown in Figure 2.7. Make sure to match pin 1 on all connections.

Figure 2.7 Multiple Internal SCSI Devices Chained Together

Detailed Installation Procedure

2-11

Step 4. Most PC cabinets are designed with a front panel LED, which

may already be connected to an existing IDE controller. You

may connect this LED cable to your SCSI host adapter, as

shown in Figure 2.8. This connection causes the front panel

LED to indicate activity on the SCSI bus.

The Busy LED connector J6, shown in Figure 2.1, is not keyed.

The J6 connector is a 4-pin one row right angle header for both

Channel A and Channel B.

Some LED cables have only two wires. In this case, place the

connector on one end of J6. If the LED does not light during

SCSI bus activity from this host adapter, you may have to rotate

the LED connector 180° on J6.

See Table A.7 in Appendix A for connector pinout information.

Figure 2.8 SCSI LED Connector

2-12

Installing the LSI21002

2.2.3.2 Making External SCSI Bus Connections

This section provides step-by-step instructions about making external

SCSI bus connections:

Step 1. To connect external SCSI devices to the LSI21002, plug the

50-pin high density connector on one end of a shielded external

high density cable (see Figure 2.3) into the host adapter

connector J3 (see Figure 2.1 and Figure 2.9).

This connector is now bracketed onto the back panel of your

computer. Figure 2.9 shows this connection.

Figure 2.9 External Cable to Host Adapter

Detailed Installation Procedure

2-13

Step 2. Plug the 50-pin high density connector on the other end of the

shielded external SCSI cable into the SCSI connector on the

external SCSI device. An example of this connection is shown

Installing the LSI21002

Step 3. To connect more than one external SCSI device to the host

adapter, chain them together with shielded external SCSI

cables. See the example in Figure 2.11.

Figure 2.11 Multiple External SCSI Devices Chained Together

2.2.4 SCSI Bus Termination

The devices that make up the SCSI bus are connected serially (chained

together) with SCSI cables. The first and last physical SCSI devices

connected on the ends of the SCSI bus must be terminated. All other

SCSI devices on the bus must have their terminators removed or

disabled.

Detailed Installation Procedure

2-15

Remember: The LSI21002 is also on the SCSI bus, and its termination

is automatically enabled when it is connected to the end of

the bus.

LVD peripheral devices are normally terminated with

external terminators, but are sometimes set with jumpers or

with a switch on the peripheral. Refer to the peripheral

manufacturer’s instructions and to your computer user’s

manual for information on how to identify the terminator

setting of each device and how to change it.

Caution:

The autoenable/disable sensing feature of Channel A on

the LSI21002 may enable termination erroneously if it is

directly cabled to another SCSI device or host adapter

using the same sensing method. The LSI21002 senses

SCSI devices by detecting the ground signal on

conductor 50 of a 68-conductor SCSI cable or conductor 22

of a 50-conductor SCSI cable. Only the SE/LVD terminators

on Channel B will always remain on.

When connecting another host adapter to a connector, termination must

be disabled on the board that is not at the end of the bus through

software control.

The LSI21002 automatically controls SCSI bus termination for four

different bus configurations, depending on the use of connectors (see

Figure 2.1). The four bus configurations are:

•

Only for internal SCSI connections,

Only for an external SCSI connection, and

Connections to both internal and external SCSI connectors

Connections to both internal connectors.

Termination on the LSI21002 for these four different bus configurations

are discussed below. Please note that only SE termination control is

allowed on Channel A.

2.2.4.1 Internal SCSI Connections

If only internal SCSI device connections on the host adapter have been

made, then terminate the last internal device on the SCSI bus. You must

disable the termination on all other devices. Termination on the LSI21002

2-16

Installing the LSI21002

is automatically enabled for Channel A. The termination for Channel B is

enabled all the time.

Figure 2.12 shows an example of how termination is determined for this

SCSI bus configuration.

2.2.4.2 External SCSI Connections

If only external SCSI device connections to the host adapter have been

made, then terminate the last external device on the SCSI bus. You must

disable the termination on all other devices. Termination on the host

adapter is automatically enabled for Channel A.

Figure 2.13 shows an example of how termination is determined for this

SCSI bus configuration on the host adapter external Channel A.

2.2.4.3 Internal and External SCSI Connections

If internal and external SCSI devices are connected to the host adapter,

then terminate the last internal and external devices on the SCSI bus.

You must disable the termination on all other devices. Termination on

Channel A of the host adapter is automatically disabled in this case.

Figure 2.14 shows an example of how termination is determined for this

SCSI bus configuration on the host adapter internal Channel A and

2.2.4.4 Internal SCSI Connections for both Internal Connectors

If internal SCSI device connections to both internal connectors (J2 and

J4) on your host adapter have been made, then terminate the internal

devices on each end of the SCSI bus. You must disable the termination

on all other devices. Termination on Channel A of your host adapter is

automatically disabled in this case. Remember, you must not use the

external connector J3 if you use both internal connectors.

2.2.4.5 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI

ID, 0–15 for a 16-bit SCSI. SCSI ID 7 is the preset host adapter setting,

giving it the highest priority on the SCSI bus. If you plan to boot your

computer from a hard disk drive on the SCSI bus, that drive should have

SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, "Configuring the

Host Adapter," explains how to set the host adapter ID using the

LSI Logic SCSI BIOS Configuration Utility.

The peripheral device SCSI IDs are usually set with jumpers or with a

switch on the peripheral. Refer to the peripheral manufacturer’s

instructions and to the user’s manual for your computer to determine the

ID of each device and how to change it. You must have no duplication of

SCSI IDs on a SCSI bus.

Note:

SCAM support is turned off by default for the BIOS version

4.11.00 and above. You may choose to turn this on to assist

in assigning SCSI IDs.

Determine the SCSI ID of each device on the SCSI bus. Note any

duplications.

2-22

Installing the LSI21002

Make any necessary changes to the SCSI IDs and record the IDs for

future reference. Table 2.1 is provided as a place to keep this record.

2.3 Setting Interrupts (Exceptional Cases)

Normally, you do not change the default interrupt routing for the

LSI21002, since performance is usually increased by having two

separate interrupts.

However, if your system does not support two separate interrupts,

INTA/INTB/ (see Figure A.1) is provided to change the interrupt routing.

This capability requires enabling the INTA/INTB/ to act as a jumper for

special configuration purposes. This feature is not packaged with the

standard LSI21002, as the default interrupt routing is sufficient for most

systems.

In the exceptional case, where a user would require jumper settings,

Table 2.2 explains these settings:

topics:

•

Section 3.1, “When to Configure the LSI21002,” page 3-1

Section 3.2, “Starting the SCSI BIOS Configuration Utility,” page 3-2

Section 3.3, “Exiting the SCSI BIOS Configuration Utility,” page 3-14

3.1 When to Configure the LSI21002

In most cases you should not need to change the default configuration

of your host adapter. You may decide to alter these default values if there

is a conflict between device settings, or if you need to optimize system

performance.

Table 3.1 and Table 3.2 list the configuration settings you can change.

The global settings effect your host adapter and all SCSI devices that are

connected to it. The device settings affect only individual SCSI devices.

3.2 Starting the SCSI BIOS Configuration Utility

If you have SCSI BIOS Version 4.XX, and it includes the LSI Logic SCSI

BIOS Configuration Utility, you can change the default configuration of

your SCSI host adapters. You may decide to alter these default values if

there is a conflict between device settings or if you need to optimize

system performance.

You can see the version number of your SCSI BIOS in a banner

displayed on your computer monitor during boot. If the utility is available,

the following message also appears on your monitor:

Press Ctrl-C to start LSI Logic Configuration Utility...

This message remains on your screen for about five seconds, giving you

time to start the utility. If you decide to press “Ctrl-C,” the message

changes to:

Please wait, invoking LSI Logic Configuration Utility...

After a brief pause, your computer monitor displays the Main Menu of the

LSI Logic SCSI BIOS Configuration utility.

NonVolatile Random Access Memory (NVRAM) is provided on the

LSI53C896 SCSI device.

3-2

Configuring the Host Adapter

Important: This utility is a powerful tool. If, while using it, you somehow

disable all of your controllers, pressing Ctrl-A (or Ctrl-E on

version 4.04 or later) after memory initialization during

reboot allows you to re-enable and reconfigure.

Not all devices detected by the Configuration Utility can be

controlled by the BIOS. Devices such as tape drives and

scanners require that a device driver specific to that

peripheral be loaded. This device driver is provided by the

device manufacturer.

3.2.1 Configuration Utility Main Menu

When you start the LSI Logic SCSI BIOS Configuration Utility, the Main

Menu appears. This menu displays a list of up to four LSI Logic PCI to

SCSI host adapters and information about each of them. The LSI21002

appears on the menu as two LSI53C896 entries; one for each channel.

To select an adapter, use only the arrow keys and enter key. Then, you

can view and/or change the current settings for that adapter and the

SCSI devices attached to it.

You can select an adapter only if Current Status is “On”. Changes are

possible since NVRAM is present on this host adapter.

The settings in this menu are global settings that affect the selected host

adapter and all SCSI devices attached to it.

SCAM Support – The LSI Logic BIOS Version 4.XX and above

supports the SCSI Plug and Play protocol called SCAM. SCAM support

by default is turned off in versions 4.11.00 and later for the LSI53C896

device. You may choose to turn it on. Note that if this BIOS is flashed

onto a board with existing settings, then these settings will not be

changed to reflect the new BIOS defaults. Go into the Configuration

Utility to change settings.

3-8

Configuring the Host Adapter

Parity – The LSI Logic PCI to SCSI host adapters always generate

parity, but some older SCSI devices do not. Therefore, you are offered

the option of disabling parity checking.

Note:

When disabling parity checking, it is also necessary to

disable disconnects for all devices, as parity checking for

the reselection phase is not disabled. If a device does not

generate parity, and it disconnects, the I/O never completes

because the reselection never completes.

Host SCSI ID – In general, it is suggested that you do not change your

host adapter ID from the default value of 7, as this gives it the highest

priority on the SCSI bus.

Scan Order – This option allows the user to tell the SCSI BIOS and

device drivers to scan the SCSI bus from low to high (0 to max) SCSI

ID, or from high to low (max to 0) SCSI ID. If you have more than one

device on the SCSI bus, changing the scan order changes the order in

which drive letters are assigned by the system. Drive order may be

reassigned differently in systems supporting the BIOS Boot Specification

(BBS). See the PCI Storage Device Management System SDMS 4.0

User’s Guide, Chapter 2 “SCSI BIOS” for additional information regarding

BBS.

Note:

The scan order option may conflict with operating systems

that automatically assign a drive order.

Removable Media Support – This option defines the removable media

support for a specific drive. When this option is selected, a window

appears with three choices:

•

None

Indicates there is no removable media support whether the drive is

selected in BBS as being first, or first in scan order in non-BBS.

Boot Drive Only

Provides removable media support for a removable hard drive if it is

first in the scan order.

With Media Installed

Provides removable media support wherever the drive(s) actually

resides.

Starting the SCSI BIOS Configuration Utility

3-9

One of these choices can be selected by highlighting it and pressing

Enter.

CHS Mapping – This option defines the cylinder head sector (CHS)

values that will be mapped onto a disk without pre-existing partitioning

information. SCSI Plug and Play Mapping is the default value.

To support interchange with noncompatible systems, there is another

option that can be selected by choosing CHS Mapping and then

cursoring to Alternate CHS Mapping.

Note:

Neither of these options will have any affect after the disk

has been partitioned with the FDISK command.

To remove partitioning, two options are available:

•

Reformat the disk using the Format Device option. See Section

3.2.2.2, “Device Selections Menu.”

Use the FDISK/MBR command at the C:\ prompt, where MBR

represents master boot record.

Important: Reformatting the disk or using FDISK/MBR erases all

partitioning and data that exists. Be careful that you target

the correct disk when using either the Format utility or the

FDISK/MBR command.

After clearing the partitions and data, it is necessary to

reboot and clear the memory or the old partitioning data will

be reused.

Spinup Delay (seconds) – This option allows the user to stagger spin

ups between devices for a longer period of time to balance the total

current load. The default value is 2 seconds with choices between 1 and

10 seconds.

This is a power management feature designed to accommodate disk

devices that may have heavy current load during power up. If multiple

drives are being powered up simultaneously and drawing heavy current

loads, then this option staggers the spin ups to limit start-up current.

Secondary Cluster Server – This option allows the user to enable an

adapter to join a cluster of adapters without doing any SCSI bus resets.

3-10

Configuring the Host Adapter

This is a requirement for Microsoft Cluster Server. The default value is

No with an alternate option of Yes.

Termination – This option allows the user to have termination control

providing an adapter has controllable termination. The default value is

Auto termination. The alternate value is Off.

3.2.2.2 Device Selections Menu
