Chapter 1 Using the SDMS Software

This chapter describes the LSI Logic Storage Device Management System (SDMS™) software, and includes these topics:

• Section 1.1, “Introduction,” page 1-1

• Section 1.2, “Overview,” page 1-2

• Section 1.3, “SDMS Device Drivers,” page 1-4

• Section 1.4, “Basic Guidelines,” page 1-4

1.1 Introduction

The LSI Logic PCI SDMS is a complete software packagethat solves the increasingly complex problem of managing system I/O. It seamlessly addresses hardware and software interfaces by supporting the LSI Logic family of SCSI processors and controllers, and a wide range of SCSI peripheral devices. At the same time, it offers interoperability across application programs, operating systems, and host platforms.

SDMS 4.0 software provides a standard method to interface SCSI I/O subsystems with devices, operating systems, and application software. It also enhances system capabilities already provided by SCSI controllers and processors by facilitating system-wide SCSI device access.

An LSI Logic SCSI controller or processor can control peripherals such as hard disk drives, CD-ROM drives, tape drives, scanners, and removable media. You can connect up to 15 wide (16-bit) SCSI peripheral devices or seven 8-bit SCSI peripheral devices (by using the SCSI bus) to a SCSI host adapter on which the SCSI controller or processor resides.

1.3 SDMS Device Drivers

The SDMS device drivers translate an operating system I/O request into a SCSI request. Each SDMS SCSI device driver is operating system speciﬁc and is designed to work on standard LSI Logic chip implementations.

Currently, LSI Logic provides PCI to SCSI device drivers for the following operating systems:

• MS-DOS 6.0/Windows 3.1X

• Windows 95, Windows 98, and Windows Me (Millennium Edition)

• Windows NT - 4.0

• Windows 2000

• OS/2 - 4.XX

• SCO OpenServer - Release 5.XX

• UnixWare - 7

• Solaris - 7 and 8

• Linux

• NetWare - 4.XX and 5.XX (NWPA)

This user’s guide provides device driver installation and conﬁguration instructions for each of these operating systems.

1.4 Basic Guidelines

Some basic rules for using SDMS software and installing a SCSI host adapter device follow. The SDMS software requires an IBM PC/AT or compatible computer with an 80486 or higher microprocessor. An understanding of basic operating system commands is assumed. In addition, users of this manual should have a general knowledge of the SCSI standard.

Before using the SDMS software, you should conﬁgure the SCSI controller into your system, taking into account the conﬁguration of other host adapters and system resources.

1-4 Using the SDMS Software

LSI Logic recommends that you back up all data before making any changes or installing any software, including LSI Logic SCSI controllers and software. Failure to adhere to this accepted computer practice may lead to loss of data. You must terminate both ends of the SCSI bus.

Refer to the hardware manuals for the devices and users’ guides for the host adapters to properly terminate the bus. Also you should locate where jumpers or dip switches are for setting SCSI ID numbers. Usually, the host adapter is ID 7. The devices are then set at IDs 0 through 6 (plus 8 through 15 for Wide SCSI). The bootable hard drive must have the lowest numerical SCSI ID, unless you are able to use the BIOS Boot Speciﬁcation (BBS). Refer to Chapter 2 for additional information regarding the BBS.

The red or blue line on a standard SCSI cable (or the black line on one end of a multicolored SCSI cable) designates pin 1 on the cable connector and must connect to pin 1 on the device and host adapter connector. Refer to the hardware manuals for the devices and the controller to locate pin 1 of the connector.

If the system already has an internal bootable hard drive (IDE, ESDI, or ST506), the drivers for the SCSI device(s) must reside on the internal bootable drive.

Chapter 2 SCSI BIOS and Conﬁguration Utility

This chapter describes the SDMS SCSI BIOS and Conﬁguration Utility. It includes these topics:

• Section 2.1, “Introduction,” page 2-1

• Section 2.2, “Boot Initialization with BBS,” page 2-3

• Section 2.3, “Using the SCSI BIOS Conﬁguration Utility,” page 2-3

• Section 2.4, “Starting the SCSI BIOS Conﬁguration Utility,” page 2-4

• Section 2.5, “Exiting the SCSI BIOS Conﬁguration Utility,” page 2-22

2.1 Introduction

The SDMS SCSI BIOS is the bootable ROM code that manages SCSI hardware resources. Itis speciﬁc to a family of LSI Logic SCSI controllers or processors. The SDMS SCSI BIOS integrates with a standard system BIOS, extending the standard disk service routine provided through INT13h.

During the boot time initialization, the SCSI BIOS determines if there are other hard disks, such as an IDE drive, already installed by the system BIOS. If there are, the SCSI BIOS maps any SCSI drives it ﬁnds behind the drive(s) already installed. Otherwise, the SCSI BIOS installs drives starting with the system boot drive. In this case, the system boots from a drive controlled by the SCSI BIOS. For version 4.05.00 and higher, LSI Logic supports the BIOS Boot Speciﬁcation (BBS).

The next section, “Boot Initialization with BBS,” discusses selecting boot and drive order.

2-2 SCSI BIOS and Conﬁguration Utility

2.2 Boot Initialization with BBS

The SDMS SCSI BIOS provides support for the BBS, which allows you to choose which device to boot from by selecting the priority.

To use this feature, the system BIOS must also be compatible with the BBS. If your system supports the BBS, then use the system BIOS setup menu to select the boot and drive order. In the system BIOS setup, the Boot Connection Devices menu appears with a list of available boot options. Use that menu to select the device and rearrange the order. Then exit saving changes to continue the boot process.

2.2.1 CD-ROM Boot Initialization

The SCSI BIOS supports boot initialization from a CD-ROM drive. The ﬁve types of emulation are:

• No emulation disk

• Floppy 1.2 Mbyte emulation disk

• Floppy 1.44 Mbyte emulation disk

• Floppy 2.88 Mbyte emulation disk

• Hard disk emulation

The type of emulation determines the drive letter assignment for the CD-ROM. For example, if you load a 1.44 Mbyte ﬂoppy emulation CD-ROM, then the CD-ROM drive would become the designated A: drive, and the existing ﬂoppy would become drive B:.

2.3 Using the SCSI BIOS Conﬁguration Utility

This section provides the menu formats and user inputs available to inform all users about this utility prior to running it. All SCSI BIOS Conﬁguration Utility screens that display various menus are partitioned into ﬁxed areas. This area provides static general help text information.

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 SCSI BIOS Conﬁguration Utility.

The following messages may appear during the boot process:

• Adapter removed from boot order, parameters will be updated

accordingly! appears when an adapteris removed from the system or relocated behind a PCI bridge.

• Configuration data invalid, saving default configuration!

appears if none of the information in NonVolatile Random Access Memory (NVRAM) is valid.

• Found SCSI Controller not in following Boot Order List, to

Add: Press Ctrl-C to start LSI Logic Configuration Utility... or Adapter configuration may have changed, reconfiguration is suggested! could appear when fewerthan four

adapters are in the boot order and adapters exist in the system which are not in the boot order.

The SDMS SCSI BIOS does not control all devices detected by this conﬁguration utility. Devices such as tape drives and scanners require that a device driver speciﬁc to that peripheral be loaded.

To make changes with this menu-driven utility, one or more LSI Logic SCSI host adapters must have NVRAM to store the changes. You can change four sets of conﬁgurations. You make changes on subordinate menus called from the Main menu, which is opened when you start the SCSI BIOS Conﬁguration Utility. The subordinate menus are:

Starting the SCSI BIOS Conﬁguration Utility 2-5

• Adapter Properties

• Device Properties

• Boot Adapter List

• Global Properties

All of these properties are controlled by menus you access through the SCSI BIOS Conﬁguration Utility’s Main menu. The Main menu also gives an overview of some properties of installed LSI Logic host adapter boards.

Important: The SCSI BIOS Conﬁguration Utility is a powerful tool.

While using it, if you somehow disable all of your controllers, press Ctrl-A (or Ctrl-E on version 4.04 or later) after memory initialization during reboot. This will allow you to re-enable and reconﬁgure your controllers. Also, if the system locks up due to NonVolatile Storage (NVS), press Ctrl-N to bypass the BIOS in order to reﬂash the card.

2.4.1 Accessing the Conﬁguration Utility Main Menu

After invoking the SCSI BIOS Conﬁguration Utility, the Main menu appears and displays a list of up to 256 PCI to SCSI host adapters in the system and information about each of them. To select an adapter, use only the arrow keys and enter key. The system scans the adapter’s SCSI bus after selecting an adapter.

Only adapters with LSI LogicControl enabled canbe accessed. Adapters without NonVolatile Memory (NVM) display default settings and cannot be changed. Figure 2.1 illustrates this menu.

Deﬁnes how the Cylinder HeadSector (CHS) values are mapped onto a disk without pre-existing partition information. SCSI Plug and Play Mapping automatically determines the most efﬁcient and compatible mapping. Alternate CHS Mapping utilizes an alternate, possibly less efﬁcient mapping that may be required if a device is moved between adapters from different vendors.

Caution: Neither of these options has any effect after a disk has been partitioned using the FDISK command. The FDISK utility is a tool that you can use to delete partition entries, one or all of them. If all partition entries are deleted, it is necessary to reboot to clear memory or the old partitioning data will be reused, thus nullifying the previous operation. Use care to ensure that the correct disk is the target of an FDISK command.

Indicates the delay in seconds between spinups of devices attached to an adapter. Staggered spinups balance the total electrical current load on the system during boot. The default value is 2 seconds.

Indicates whether an adapter has one or more devices attached that are shared with one or more other adapters. Therefore, the SDMS SCSI BIOS should avoid SCSI bus resets as much as possible.

This option allows you to enable an adapter to join a cluster of adapters without doing any SCSI bus resets. This is a requirement for the Microsoft Cluster Server. The default value is No with an alternate option of Yes.

2.4.3 Device Properties Menu

The Device Properties menu allows you to view and update individual device settings for an adapter. Changing a setting for the host device (for example, SCSI ID 7) changes the setting for all devices. The number of ﬁelds displayed requires the menu to scroll left/right in order to display the information. When accessing this menu online, use the Home/End keys to scroll to columns currently not displayed. The scroll indicator on the bottom of the menu shows where the cursor is relative to the ﬁrst and last columns. The example for the Device Properties menu is split (Figure 2.3 and Figure 2.4) due to the width of its multiple ﬁelds/columns.

3.1 Introduction

Windows 95, Windows 98, and Windows Millennium Edition (Me) are operating systems designed to run on Intel processors using current technology. This chapter refers to Windows 95, Windows 98, and Windows Me as Windows 95/98/Me in many instances.

Windows 95/98/Me provides a graphical user interface (GUI) environment incorporating many high-level features. Refer to the Microsoft Windows 95/98/Me documentation for more details. An I/O manager handles I/O requests by going through the appropriate drivers to address a SCSI peripheral.

Windows 95/98/Me provides class drivers for hard disk, ﬂoptical, CD-ROM, printer, and scanner peripherals. Other class drivers, provided by peripheral manufacturers, are added to support new devices. Microsoft provides the port driver and LSI Logic provides the miniport drivers, which are called SYMC8XX.MPD, SYM_HI.MPD, and SYM_U3.MPD.

3.1.1 Features

These drivers complete the path to an LSI Logic controller or processor with an optional SDMS SCSI BIOS.

LSI Logic uses the same ﬁlenames for their drivers for different Windows operating systems. The driver ﬁles are packaged either in separate subdirectories based on the Windows operating system or on different ﬂex disks. To determine the driver ﬁle for Windows 95/98/Me, note that the ﬁlename ends with .MPD. The following sections describe these drivers and their installation.

The SDMS device drivers for Windows 95/98/Me support these features:

• Ultra160 data transfers (for LSI53C1000 and LSI53C1010)

• Domain Validation (for the SYM_U3.MPD driver only)

• Parallel Protocol Request (PPR) (for the SYM_U3.MPD driver only)

3.1.3 Description

The SYMC8XX.MPD, SYM_HI.MPD , and SYM_U3.MPD drivers conform to the Microsoft speciﬁcation for miniport drivers. These drivers allow connection of SCSI devices including disk drives, CD-ROMs, and tape drives for PCI-based machines. To support a new SCSI device, Windows 95/98/Me architecture requires that a class driver for that type of device bepresent. These are usually supplied by Microsoft, or possibly by the peripheral manufacturer. No changes to SYMC8XX.MPD, SYM_HI.MPD ,orSYM_U3.MPD are required. These drivers are only supported under Windows 95/98/Me.

Introduction 3-3

ITI6200U3LP).

A Windows application passes SCSI commands directly to the SCSI devices by using the SCSI pass-through facility. Refer to Microsoft Windows 95/98/Me documentation for more details. This facility allows applications to directly control and access SCSI devices by ﬁlling in a data structure and calling into the port driver.

The SYMC8XX.MPD and SYM_HI.MPD drivers support Ultra SCSI protocol, providing twice the raw data transfer rate of Fast SCSI for disk drives and LSI Logic host adapters that support Ultra SCSI. These drivers also support Ultra2 SCSI protocol, providing quadruple the raw data transfer rate of Fast SCSI.

The SYM_U3.MPD driver supports Ultra160 SCSI protocol providing up to 160 Mbytes/s data transfer for double transition. Ultra160 also includes CRC, PPR, and Domain Validation. The standard Ultra160 SCSI protocol performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI.

Caution: Ultra SCSI requires more stringent SCSI bus cabling

setups than Fast SCSI. Ultra2 SCSI and Ultra160 SCSI require Low Voltage Differential (LVD) termination.

3.2 Using the SYMC8XX/SYM_HI/SYM_U3 Drivers

If you do not encounter any problems, the new driver is operating properly. Otherwise, consult Section 3.4, “Troubleshooting,” for additional information.

3.4 Troubleshooting

Some potential problems and their suggested solutions are:

During installation, no SCSI devices are found.

• Ensure that all devices are powered on and terminated correctly.

• Check that no devices have duplicate SCSI IDs.

• Make sure INTA is assigned for the PCI slot(s) where your SCSI host

adapter(s) are installed.

• Be sure that all devices appear properly in the display banner of the

SDMS SCSI BIOS at boot time.

Problems with Ultra SCSI devices using Ultra SCSI protocol.

the system is not performing optimally and methods to correct

the problem.

If the system is conﬁgured with an LSI Logic host adapter that supports Ultra SCSI, an Ultra SCSI device is on the SCSI bus, and Ultra SCSI support by the SYMC8XX.MPD, SYM_HI.MPD,orSYM_U3.MPD driver is enabled, intermittent problems and possible system crashes can occur. It may be that the SCSI bus cable and terminators do not conform to the Ultra SCSI speciﬁcation.

To resolve problems with Ultra SCSI devices, follow these steps: Step 1. Disable Ultra SCSI support using the procedure described in

Section 3.5.1, “Enabling/Disabling Ultra SCSI Support,”

page 3-15 if the system is bootable.

Hold down the F8 function key when Starting Windows

95/98/Me... appears if the system is not bootable to

Windows 95/98/Me. Step 2. Select Safe Mode.

Troubleshooting 3-13

Step 3. Disable Ultra SCSI support using the procedure described

Section 3.5.1, “Enabling/Disabling Ultra SCSI Support,” once

the system is booted.

If the system operates properly without Ultra SCSI enabled, it

is highly likely that the SCSI bus cable and terminators are not

conﬁgured correctly for Ultra SCSI. Refer to the LSI Logic host

adapter user’s guide for information on Ultra SCSI cabling

requirements. Step 4. Verify that the devices appear with the proper value for speed

in the SDMS SCSI BIOS banner at boot time. Refer to

Chapter 2, “SCSI BIOS and Conﬁguration Utility,” for additional

details.

Problems with scanners.

If a scanner is not operating properly (either the scanner is not found or a SCSI interface error occurs during scanning), it is possible that the third party scanner drivers do not support the auto request sense feature of LSI Logic host adapters. Disable the auto request sense feature as described in Section 3.5.2, “Disabling Auto Request Sense Support,” and try the scanner operation again.

The system hangs at boot, has a long boot time, or SCSI device not available.

Some older SCSI devices do not tolerate Domain Validation operations. At system boot time, Domain Validation is performed to test the data integrity of the SCSI bus between the host adapter and each target device. With some older SCSI devices, these operations can cause the device to stop responding to SCSI commands.

Refer to the Command Line Options Section 3.5.4, “Disabling Domain

Validation Support,” page 3-17. Disable this support as described either

for a speciﬁc problem SCSI target or all adapters controlled by the SYMC8XX.MPD, SYM_HI.MPD,orSYM_U3.MPD driver.

3.5 Using the Command Line Options

This section describes various command line options that allow changes to the host adapter.

3-14 Windows 95, Windows 98, Windows Me Device Driver Installation

3.5.1 Enabling/Disabling Ultra SCSI Support

Settings in the adapter NVRAM control Ultra SCSI support. These settings can be viewed or changed through the SCSI BIOS Conﬁguration Utility. During system boot, after the LSI Logic PCI SCSI BIOS banner, the message Press Ctrl-C to start Configuration Utility appears for a few seconds.

To enable/disable Ultra SCSI support, follow these steps: Step 1. Press Ctrl-C to start this utility.

Step 2. Select one of the adapters displayed, then select Device

Properties.

This shows the Sync Rate for each device and the selected

adapter. Step 3. Set the speed to 20 Mbytes/s for an Ultra device (for width of

8) or 40 Mbytes/s (for width of 16).

Set the speed to 10 Mbytes/s (for width of 8) or 20 Mbytes/s

(for width of 16) to disable Ultra. If the speed of the adapter

itself is changed, the speed for all devices will be set no higher

than the adapter speed.

3.5.2 Disabling Auto Request Sense Support

When the system installs the SYMC8XX.MPD, SYM_HI.MPD , and/or SYM_U3.MPD drivers, support for auto request sense is enabled. Auto

request sense is a feature of the adapter where certain device information is obtained automatically without system control, thereby increasing overall performance. However, some third party peripheral drivers do not support the use of auto request sense, resulting in perceived device failures.

To allow these devices to operate properly, the auto request sense feature can be disabled using the Device Manager on a per adapter basis. Follow this procedure to disable auto request sense support:

Step 1. Click on the Start button. Select Settings-->Control Panel. Step 2. Double click on the System icon.

Using the Command Line Options 3-15

Step 3. Click on the Device Manager tab. Step 4. Either double click on the SCSI controllers entry or click once

on the plus sign to the left of it.

One entry for each host adapter installed in the system

appears. Step 5. Select the desired adapter, and click on the Properties button. Step 6. Click on the Settings tab. Step 7. Type DisableAutoReqSense=1;. If there is already an entry

displayed, type the above at the end of the existing entry. Be

sure to include the semicolon. Step 8. Click OK to exit the Settings tab. Step 9. Click OK again.

If the entry was changed, the System Settings Change dialog

box appears. Step 10. Click Yes to restart the computer.

After the system reboots, auto request sense is disabled for the selected adapter. To re-enable auto request sense, delete the entry that was made above. If other entries exist, be sure to leave them intact.

3.5.3 Enabling SCAM Support

SCAM is a protocol that allows SCAM-compliant peripherals to assign their SCSI IDs dynamically at boot time, eliminating the need for you to check and set unique SCSI IDs. The SDMS PCI BIOS and the SYMC8XX.MPD , SYM_HI.MPD, and SYM_U3.MPD drivers have this feature disabled by default.

Some peripherals haveproblems with the SCAM protocol, resultingin the device either not being seen by the operating system, or not working correctly. Windows 98 and Windows Me do not support the use of SCAM.

If you desire usage of the SCAM protocol, follow these steps to enable SCAM

Step 1. Click on the Start button. Select Settings-->Control Panel. Step 2. Double click on the System icon.

appears. Step 5. Select the adapter desired, then click the Properties button. Step 6. Click on the Settings tab. Step 7. Type in the Adapter settings entry:

do_SCAM=1;

If an entry already appears there, type the above at the end of

the existing entry. Be sure to include the semicolon. Step 8. Click OK to exit the Settings tab. Step 9. Click OK again.

If you changed the entry, the System Settings Change dialog

box appears. Step 10. Click Yes to restart the computer.

After the system reboots, SCAM is enabled for the selected adapter. To disable SCAM, delete the entry that was made above. If other entries exist, be sure to leave them intact.

3.5.4 Disabling Domain Validation Support

When the SYMC8XX.MPD , SYM_HI.MPD ,orSYM_U3.MPD driver is installed, support for Domain Validation is enabled. Domain Validation is a feature of the adapter where the data transfer speed between the adapter and each target is tested at system boot. If the test fails, the data transfer speed is reduced and the test is repeated until a supported data transfer speed is found.

However, some older SCSI devices do not properly support the standard SCSI commands used during this testing, resulting in the system not booting or a device not available. To allow these devices to operate properly, you can disable the Domain Validation feature by using the Device Manager for all adapters controlled by the respective driver, or by using the SCSI BIOS Conﬁguration Utility on a per device basis.

Using the Command Line Options 3-17

To disable Domain Validation support for all adapters controlled by the SYMC8XX.MPD , SYM_HI.MPD,orSYM_U3.MPD driver, follow these steps:

Step 1. Click on the Start button. Select Settings-->Control Panel. Step 2. Double click on the System icon. Step 3. Click on the Device Manager tab. Step 4. Either double click on the SCSI controllers entry, or click once

on the plus sign to the left of it.

of the existing entry. Be sure to include the semicolon. Step 8. Click OK to exit from the Settings tab. Step 9. Click OK again.

If the entry was changed, the "System Settings Change" dialog

box appears. Step 10. Click Yes to restart the computer.

After the system reboots, Domain Validation is disabled for

adapters controlled by the selected driver. To re-enable Domain

Validation, delete the entry that was made above. If other

entries exist, be sure to leave them intact. To disable Domain Validation support for a selected device, using the

SCSI BIOS Conﬁguration Utility, follow these steps: Step 1. Press Ctrl-C to start this utility when prompted to do so

during system boot. Step 2. Select the desired adapter and press Enter. Step 3. Choose "Device Selections" and press Enter.

3-18 Windows 95, Windows 98, Windows Me Device Driver Installation

This shows the Sync Rate and Width for each device and the

selected adapter. Step 4. Set the Sync Rate to 0 and Width to 0 for the selected device.

This sets the device to asynchronous/narrow transfers and

Domain Validation functions are not issued to this device. Step 5. Exit the SCSI BIOS Conﬁguration Utility and save changes.

3.5.5 Multiple LSI Logic Host Adapters Considerations

If multiple LSI Logic PCI SCSI host adapters are installed in the system, special actions are sometimes required to install or change drivers. This is due to the fact that the bundled driver supports some LSI Logic host adapters, and also that one SDMS device driver can support multiple LSI Logic host adapters installed in the system.

With multiple LSI Logic adapters, it is possible to have a situation where one adapter is assigned to one driver, and another is assigned to a different version of the same driver. This can cause conﬂicts that may cause the system to switch to real-mode drivers, affecting performance and access to CD-ROM or tape drives.

When installing additional boards or updating drivers, only one version of the appropriate driver controls all the LSI Logic host adapters. To update your system to the correct driver, two methods are available.

3.5.5.1 Method 1

Follow these steps: Step 1. Change the driver for a particular host adapter to the desired

driver by using the Device Manager. Step 2. Click No when prompted to reboot the system for the new

settings to take effect. Step 3. Change drivers for all LSI Logic host adapters in the system

supported by that same driver to the new driver, and reply No

to rebooting until the ﬁnal adapter is changed.

If booting from a SCSI device, ensure that the adapter

controlling this device is the last one changed.

Using the Command Line Options 3-19

3.5.5.2 Method 2

Follow these steps: Step 1. Determine which driver ﬁle is active for all adapters through the

Properties tab in Device Manager. Go to the:

\WINDOWS\SYSTEM\IOSUBSYS

directory and rename the driver ﬁle to an extension other than

MPD. Step 2. Reboot the system.

While booting, the system may ask to load the bundled driver

ﬁle from the Windows 95/98 installation disk. Step 3. Click OK. Step 4. Click Skip File when the system says it cannot ﬁnd the ﬁle.

Repeat this step for all adapter messages while booting. Step 5. Use the Device Manager to change the driver for each adapter

to the desired driver after the system is booted. Step 6. Do not reply Yes to reboot the system until the ﬁnal adapter has

been changed.

3.6 Using SCSI Tools for Windows 95/98

SDMS SCSI Tools software for Windows 95/98 is a support utility that provides a mechanism for examining host adapters and SCSI devices within the Windows 95/98 environment. Under Windows 95/98, the ASPI support is bundled with the operating system.

3.6.1 Features

4.1 Introduction

Windows NT 4.0 is an operating system designed to run on processors using current technology. It provides a graphical user interface environment that incorporates many high-level features. Refer to the Microsoft Windows NT documentation for more information. An I/O manager handles I/O requests in Windows NT by going through the appropriate drivers to address a SCSI peripheral.

Windows NT provides class drivers for hard disk, ﬂoptical, CD-ROM, printer, and scanner peripherals. Other class drivers, provided by peripheral manufacturers, may be added to support new devices. Tape device support is built into the operating system itself and does not

PCI Storage Device Management System SDMS 4.0 User’s Guide 4-1

require a class driver. Microsoft provides the port driver and LSI Logic provides the miniport drivers, which are called SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS. These drivers complete the path to an LSI Logic controller or processor with an optional SDMS SCSI BIOS.

To determine the operating system version, go into Windows Explorer, display the driver ﬁle, right click on the ﬁlename, click on Properties, and click on the Version tab. Finally, click on the Internal Filename in the lower section. For Windows NT 4.0, the ﬁlename appears as ﬁlename (NT 4.0). For example, SYMC8XX.SYS (NT 4.0).

The sections below describe these drivers and their installations.

• LSI53C895A (LSI8953U)

• LSI53C896 (LSI22910, LSI21002, LSI22902)

The SYM_U3.SYS driver is named “Symbios Ultra3 PCI SCSI Driver” for driver installation. It supports the following devices and their associated LSI Logic host adapters:

• LSI53C1000 (LSI20160, LSI20160L)

• LSI53C1010 (LSI21040, LSI22915A, LSI22903, LSI21003,

4.1.3 Description

The SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS drivers meet the Microsoft speciﬁcation for miniport drivers. These drivers allow connection of SCSI devices including disk drives, CD-ROMs, and tape drives for PCI-based machines.

To support a new SCSI device, the Windows NT architecture requires that a class driver for that type device be present (usually supplied by Microsoft, or possibly by the peripheral manufacturer). No changes to SYMC8XX.SYS, SYM_HI.SYS,orSYM_U3.SYS are required. These drivers

Introduction 4-5

ITI6200U3LP).

are only supported under Windows NT 4.0 and later versions. They do not run under earlier versions of Windows NT.

A Windows application passes SCSI commands to the SCSI devices by using the SCSI pass-through facility. Refer to the Microsoft Windows NT 4.0 documentation for more information. This facility allows applications to directly control and access SCSI devices by ﬁlling in a data structure and calling into the port driver or class driver.

The SYMC8XX.SYS and SYM_HI.SYS drivers support Ultra SCSI protocol, providing twice the raw data transfer rate of Fast SCSI. These drivers also support Ultra2 SCSI protocol, providing quadruple the raw data transfer rate of Fast SCSI.

The SYM_U3.SYS driver supports the Ultra160 SCSI protocol providing up to 160 Mbytes/s data transfer rates using double transition clocking. Ultra160 also includes CRC, PPR, and Domain Validation. The Ultra160 SCSI protocol performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI.

Caution: Ultra SCSI requires more stringent SCSI bus cabling

setups than Fast SCSI. Ultra2 and Ultra160 require LVD termination.

The SDMS driver bundled in Windows NT 4.0 is named SYMC810.SYS. When Windows NT selects the bundled SDMS driver during setup, the driver information (that is, “Symbios C810 PCI SCSI Host Adapter”) appears. Although this implies that the driver only supports the LSI53C810, it actually supports the LSI53C810, LSI53C810A, LSI53C815, LSI53C825, LSI53C825A, LSI53C860, LSI53C875, and LSI53C876.

This bundled driver does not “see” or “support” the LSI53C885, LSI53C895, LSI53C896, LSI53C895A, LSI53C1000, and LSI53C1010 chipsets and any newer host adapters based on these chipsets that LSI Logic currently produces.

Note: Keep in mind that the Windows NT 4.0 setup only displays

the driver information, not every controller found by that driver.

4.2 Using the SDMS Windows NT Drivers

The SDMS Software Device Drivers and Utilities CD-ROM contains the

SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS drivers at this location:

{CD-ROM Drive Letter}:\ DRIVERS\WINNT

You must prepare an SDMS Driver Diskette before proceeding with the installation instructions.

4.2.1 Preparing an SDMS Driver Diskette

Various subdirectories contain the miniport drivers and their associated ﬁles. The subdirectory structure is:

{CD-ROM Drive Letter:} \DRIVERS\WINNT\XXXXX\I386

where XXXXX represents the speciﬁc Windows NT subdirectory. For example, the SYMC8XX.SYS driver is located in the 8XXNT subdirectory. Copy all the ﬁles starting from the I386 subdirectory through the MINIPORT subdirectory (I386/WINNT/MINIPORT) to the root directory of a clean diskette. You will use this SDMS driver diskette during installation.

You may also obtain the Windows NT 4.0 drivers from the LSI Logic web site at: http://www.lsilogic.com.

can be installed one after the other without rebooting for each one. Installation order is not important.

Step 15. Reboot your computer to load the new miniport driver(s).

4.4 Performance Tuning for Windows NT 4.0

Windows NT 4.0 has registry entries that can be used to increase the performance of SCSI I/O for certain conﬁgurations. The tunable parameters include large transfer block size support and a guaranteed number of concurrent I/Os for a particular SCSI bus.

4.4.1 Supporting Large Block Size

The SYMC8XX.SYS, SYM_HI.SYS, and SYM_U3.SYS drivers can support up to a 1 Mbyte transfer size in Windows NT 4.0. However, in Windows NT 4.0, the default transfer size is 64 Kbytes. To enable a larger transfer size, an entry must be added to the registry by using the SYM_256K.REG ﬁle. This ﬁle will set a 256 Kbytes maximum, but it can be edited to set other desired maximum transfer sizes.

Important: Be sure to read the information in the SYM_256K.REG data

ﬁle before editing it.

Choose one of two methods to add this registry setting:

1. Locate the SYM_256K.REG data ﬁle (supplied with the driver ﬁles)

using Windows Explorer and double click on the ﬁle. or

2. Type at the command prompt:

REGEDIT SYM_256K.REG

This inserts an entry into the registry to enable 256 Kbytes block size support.

Editing the SYM_256K.REG ﬁle can set any maximum block size between 64 Kbytes and 1 Mbyte (− 8 Kbytes). The formula to calculate the proper value for MaximumSGList is:

MaximumSGList = (Maximum Block Size)/4K +1

Performance Tuning for Windows NT 4.0 4-13

For 256 Kbytes: 256 Kbytes/4 Kbytes = 64, add 1 for 65 (decimal) or 0x41 (hexadecimal). The maximum value allowed for MaximumSGLIst is 255 or 0xFF. This denotes an absolute maximum transfer size of 1040384, which is 8 Kbytes less than 1 Mbyte (1040384/4K = 0xFE, add 1 for 0xFF or 255).

Reboot your system for the new registry setting to be effective. To reset the maximum block size to the default of 64 Kbytes, follow the instructions above, and use SYMDFBLK.REG as the data ﬁle.

4.4.2 Maximum Number of Concurrent I/Os (Guaranteed)

Windows NT 4.0 only guarantees a maximum of 32 concurrent I/Os active on a particular SCSI bus. However, due to the method of memory allocation, the actual limit of concurrent I/Os can vary greatly between various drivers or versions of drivers. This can have a huge impact on performance benchmarking between different driver versions or adapter vendors. In effect, one adapter may actually be able to have 70 or 80 I/Os outstanding, while another adapter could only have 32. This can affect systems with high performance storage subsystems, such as disk arrays.

Important: Be sure to read the information in the SYM100IO.REG data

ﬁle before editing it.

In order to have a guaranteed number of concurrent I/Os, an entry must be added to the registry, using the SYM100IO.REG. ﬁle for the SDMS miniport drivers.

Choose one of two methods to add this registry setting:

1. Locate the SYM100IO.REG data ﬁle (supplied with the driver ﬁles)

using Windows Explorer and double click on the ﬁle. or

2. Type at the command prompt:

REGEDIT SYM100IO.REG

This inserts an entry in the registry to guarantee a maximum of 100 concurrent I/Os per adapter.

If a maximum other than 100 is desired, the SYM100IO.REG ﬁle can be edited. The system administrator should be aware that increasing the

4-14 Windows NT 4.0 Device Driver Installation

number of concurrent I/Os from the default of 32 will use increasing amounts of nonpaged pool memory. High values for this setting can degrade system performance.

Reboot the system for the new registry setting to be effective. To reset the guaranteed number of concurrent I/Os to the default of 32, follow the instructions above, and use the SYMDEFIO.REG data ﬁle.

4.4.2.1 Auto Request Sense

Enabling and Disabling Auto Request Sense is found in Section 4.5,

“Troubleshooting.”

4.4.3 Disk Mirroring

This section applies only to Intel x86 platforms where the SDMS 4.XX SCSI BIOS is used.

The SDMS 4.XX SCSI BIOS loads only one image into system memory at boot time regardless of how many host adapters are used in the system. All of the disk drives on all host adapters are recognized through the INT13h function call. Due to this implementation, disk mirroring under Windows NT needs to be done if it is desired. Disk mirroring allows booting from the mirrored partition in case the primary partition fails.

Note: These instructions may be different from Microsoft

documentation. To create an NT Fault Tolerant (FT) diskette, follow these instructions: Step 1. Format a diskette in drive A: using NT (File Manager or

Windows Explorer) for use as a FT boot ﬂoppy.

Step 2. Copy NTLDR, NTDETECT.COM, and BOOT.INI from the root

directory of the primary partition to this diskette.

Step 3. Temporarily remove the read only attribute of the BOOT.INI ﬁle

so that it can be modiﬁed and saved.

Step 4. Edit BOOT.INI on the FT diskette and modify the following line

where you want to boot the mirrored partition.

MULTI(0)DISK(0)RDISK(X)PARTITION(Y)\<WINNT_DIRECTORY>

where:

Performance Tuning for Windows NT 4.0 4-15

multi(0) and disk(0) should always remain the same, and X = the drive number of the mirrored partition in the INT13h

chain minus 80h. The drive number of the mirrored partition can be found during

system bootup of the SDMS 4.XX SCSI BIOS when the primary partition does not exist. It should say either BOOT (= 80h), 81h, 82h, and higher. Therefore, the value of X would be 0 when BOOT, 1 when 81h, 2 when 82h, etc.

Y = the partition number on the drive (starts at 1 which equals single partition on the drive)

The next example provides a scenario to better illustrate the above information.

Example: Two LSI Logic 8XX host adapters are in the system. The ﬁrst host adapter, #0 which is the boot path, has two SCSI

hard drives on ID 0 and ID 5. The second host adapter, #1, has two SCSI hard drives on ID 2 and ID 4. Assuming that the SCSI bus scan starts from ID 0 and goes up, the drive number of INT13h will look like this:

Host Adapter #0, ID 0 = BOOT (which is 80h) Host Adapter #0, ID 5 = 81h Host Adapter #1, ID 2 = 82h Host Adapter #1, ID 4 = 83h Now Windows NT is installed on the boot drive, host adapter

#0 ID 0, and a mirrored partition is established on host adapter #1 ID 2. If the primary partition fails, for example due to power failure, then the drive number of INT13h will change:

Host Adapter #0, ID 5 = BOOT (which is 80h) Host Adapter #1, ID 2 = 81h Host Adapter #1, ID 4 = 82h Therefore, to boot from the mirrored partition, enter this line in

the BOOT.INI ﬁle on the NT FT boot ﬂoppy:

MULTI(0)DISK(0)RDISK(1)PARTITION(1)\<WINNT_DIRECTORY

where the host adapter is #1 with ID 2. Note that RDISK(1) was calculated from x = 81h − 80h.

4-16 Windows NT 4.0 Device Driver Installation

Step 5. Save the BOOT.INI ﬁle and restore the “read only” attribute.

4.5 Troubleshooting

Some potential problems and their suggested solutions are:

During installation, no SCSI devices are found.

• Ensure that the custom setup is chosen on the Setup Method

screen.

• Ensure that all devices are powered on and terminated correctly.

• Check that no devices have duplicate SCSI IDs.

• Make sure INTA is assigned for the PCI slot(s) where your SCSI host

adapter(s) are installed.

SDMS SCSI BIOS at boot time.

• For systems with some versions of the Award BIOS, ensure that the

PCI IRQ is set to edge triggered.

System crashes during installation with a message indicating inaccessible boot device.

• This error is usually associated with an IRQ, DMA channel, I/O (chip)

address, or BIOS address conﬂict. Set the SCSI host adapter to use a different interrupt through the system BIOS in CMOS.

• A virus sometimes causes this error that infects the Master Boot

Record of the boot device. Use a write-protected DOS bootable ﬂex containing virus scanning and cleaning software to check for any viruses on the boot device, and remove if any are found.

A disk drive is recognized as seven different devices when only one is physically connected to the SCSI bus.

Older SCSI devices that incorrectly indicate to Windows NT that they support multiple LUNs usually cause this error.

• Contact the device manufacturer for a ﬁrmware upgrade.

• Ensure that there are no devices with the same SCSI ID as the host

adapter board.

Troubleshooting 4-17

Problems with SCSI devices installation or operation.

If a SCSI device is not operating properly (either the device is not found or a SCSI interface error occurs during scanning), it is possible that the third party device drivers do not support the auto request sense feature of LSI Logic host adapters. Disable the auto request sense feature as described below and try the device operation again.

Step 1. To disable the auto request feature, use the SYMNO_AR.REG ﬁle

supplied with the SDMS driver ﬁles for Windows NT, either double click the ﬁle in Windows Explorer/File Manager.

or Type REGEDIT SYMNO_AR.REG at the command prompt. This inserts a registry entry that disables the auto request

sense feature. The system must be rebooted for this change to take effect.

Step 2. To re-enable the auto request sense feature, use the

SYM_AUTO.REG ﬁle and perform one of the update methods as described in the preceding paragraph.

Problems with certain SCSI devices when using an Ultra SCSI adapter.

Some SCSI devices do not function properly when the adapter attempts to negotiate Ultra SCSI transfer rates. If a device is not operating properly, check the transfer speed setting using the SDMS 4.XX SCSI BIOS Conﬁguration Utility (press Ctrl-C when the LSI Logic SDMS PCI BIOS banner appears during the system boot process). Devices that do not support Ultra SCSI should be set to a maximum of 10 Mbytes/s for 8-bits, or 20 Mbytes/s for 16-bits.

Problems with Ultra SCSI devices using Ultra SCSI protocol.

• If the system is conﬁgured with an LSI Logic host adapter that

supports Ultra SCSI and an Ultra SCSI device is on the SCSI bus, intermittent problems and possible system crashes can occur if the SCSI bus cable and terminators do not conform to the Ultra SCSI speciﬁcation.

• Disable Ultra SCSI support for all devices using the SDMS 4.XX

SCSI BIOS Conﬁguration Utility (press Ctrl-C when the LSI Logic PCI SCSI BIOS banner appears during the system boot process).

4-18 Windows NT 4.0 Device Driver Installation

• If the system operates properly without Ultra SCSI enabled, it is

highly likely that the SCSI bus cable and terminators are not conﬁgured correctly for Ultra SCSI. Refer to the appropriate LSI Logic Host Adapter User’s Guide as listed in the Related Publications section on page v.

At Ultra3 speed (160 Mbytes/s), the system hangs (waits forever), has a long boot time, or SCSI device is not available.

To resolve this problem, disable Domain Validation either for a speciﬁc SCSI target or all adapters controlled by the driver. To do so, follow these steps:

• To disable Domain Validation for a speciﬁc SCSI target, use the

SDMS 4.XX PCI SCSI BIOS Conﬁguration Utility to set the Sync Rate to 0 (async) and the Data Width to 8. This target will now run in async/narrow mode and no Domain Validation operations will be performed on it.

• To disable Domain Validation for all host adapters controlled by this

driver, use the SYMNO_DV.REG ﬁle (supplied with the SDMS Windows NT driver ﬁles).

Either double click on the ﬁle in Windows Explorer/File Manager or Type REGEDIT SYMNO_DV.REG at the command prompt. This inserts a registry entry that disables Domain Validation

operations. You must reboot your system for the new registry setting to take effect.

• To re-enable the Domain Validation feature, use the SYM_DOMV.REG

ﬁle and perform one of the update methods described in the preceding paragraph.

Troubleshooting 4-19

4.6 Using the NT Conﬁguration Utility

You may use the NT Conﬁguration Utility to change selected conﬁguration parameters of LSI Logic SCSI host adapters. You must have installed Windows NT 4.0 and the latest SDMS Windows NT driver(s) (SYMC8XX.SYS, SYM_HI.SYS,orSYM_U3.SYS) to match your hardware prior to using this utility. You may decide to alter conﬁguration values if a conﬂict exists between device settings or if you need to optimize system performance. You must reboot the system for the changes to take effect. During boot, the version number of Windows NT appears in a banner on the computer monitor.

Important: The NT Conﬁguration Utility may be used with Windows

2000 in conjunction with the following LSI Logic device

drivers:

SYMC8XX.SYS, version 4.16 or later,

SYM_895A.SYS, version 4.16 or later,

SYM_HI.SYS, version 4.16 or later

SYM_U3.SYS, version 5.08 or later

These drivers may be obtained from the LSI Logic Website

(www.lsilogic.com) or on the SDMS Software Device

Drivers and Utilities CD-ROM, release 4.8. Since Windows NT and the SDMS Windows NT drivers do not need the

adapter's BIOS to operate, only a limited number of the conﬁguration parameters that can be changed by this utility will have any impact on the system once rebooted. These parameters are:

• SCSI ID of the adapter

• Wide data bits setting

• Synchronous rate (Mbytes/s)

If you have Windows NT 4.0 and are using the SDMS SYM_U3.SYS driver, the NT Conﬁguration Utility allows you to perform Domain Validation testing on the installed LSI Logic LSI53C1000 or LSI53C1010 host adapter and connected devices. This testing veriﬁes that the installed LSI Logic hardware functions correctly with the conﬁguration information (synchronous speed and bus width) set through either the SCSI BIOS Conﬁguration Utility or by using the capabilities of this utility.

4-20 Windows NT 4.0 Device Driver Installation

Changes to the wide data bit setting and/or synchronous rate can be made during this testing to ensure functionality. These settings can also be saved in a similar way as when doing the conﬁguration settings. The difference when saving these new values during Domain Validation testing is that they are in effect immediately, and no system reboot is necessary.

Important: The companion product to the NT Conﬁguration Utility is

the Domain Validation Utility, which monitors the

SYM_U3.SYS miniport driver. Refer to Section 4.7, “Using

the Domain Validation Utility,” for more information.

4.6.1 Installing the NT Conﬁguration Utility (x86 Platforms)

You execute an InstallShield program to install the NT Configuration Utility. Use the SDMS Software Device Drivers and Utilities CD-ROM that contains the InstallShield program to perform the installation.

Run the SETUP.EXE program directly from:

{CD-ROM Drive Letter}: \UTILITY\WINDOWS\NTCONFIG\I386

A shortcut icon appears automatically on the desktop after installation.

4.6.2 Starting the NT Conﬁguration Utility

4.6.2.1 Main Menu

To start the NT Conﬁguration Utility, double click on the shortcut icon. After a brief pause, yourcomputer monitor displaysthe Main Menu of this utility.

To make changes with this menu-driven utility, one or more LSI Logic SCSI host adapters installed in the system must have NVRAM to store the changes. Also, due to Windows NT constraints, each of the adapters must have at least one hard drive attached to it so that NT Conﬁguration can properly identify the adapter.

Important: The NT Conﬁguration Utility is a powerful tool. The system

can be rendered inoperable if care is not taken when

reconﬁguring the parameters.

After starting the NT Conﬁguration Utility, the Main menu appears and displays a summary list of all LSI Logic PCI to SCSI host adapters in

Allows you to disable parity checking, since the LSI Logic PCI to SCSI host adapters always generate parity. Note that some older SCSI devices do not generate parity.

Note: When disabling parity checking, you must also 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.

Indicates the host adapter’s SCSI ID, which is a unique number used to identify the device on the SCSI bus.

Note: In general, LSI Logic suggests that you do not change the host adapter ID from the default value of 7, as this gives it the highest priority on the SCSI bus. Note that if you have 8-bit SCSI devices, these devices cannot see host IDs greater than 7.

Allows you to tell your device drivers to scan the SCSI bus from low-tohigh (0 .. 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.

Note: This scan order option may conﬂict with operating systems that automatically assign a drive order.

Tells the host adapter whether or not to allow a device to disconnect. SCSI devices have the ability to disconnect from the initiator during an I/O transfer. This disconnect frees the SCSI Bus to allow other I/O processes. Some devices run faster with disconnects enabled (mostly newer devices), while some run faster with disconnects disabled (mostly older devices).

Sets the amount of time the host adapter waits for a read, write, or seek command to complete before trying the I/O transfer again. Since this provides a safeguard that allows the system to recover if an I/O operation fails, LSI Logic recommends that you always set the time-out to a value greater than zero.

Set this option to No when you do not want a speciﬁc device available to the system. Also, on a bus with only a few devices attached, you can speed up boot time by changing this setting to No for all unused SCSI IDs.
