1.3 Interface Descriptions

This section provides a more detailed explanation about the PCI Interface, the SCSI Interface, Ultra2 SCSI Technology, and LVDlink Technology.

1.3.1 The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O components to the processor and memory subsystems in equipment ranging from PCs to servers. The PCI functionality for the LSIU80ALVD is contained within the LSI53C895A. The LSI53C895A connects directly to the PCI bus and generates signal timing and bus protocol in compliance with the PCI Speciﬁcation Revision 2.1.

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 LSIU80ALVD conforms to the PCI universal signaling environment for a 5 V or 3.3 V PCI bus.

Interface Descriptions 1-3

1.3.2 The SCSI Interface

The SCSI functionality for the LSIU80ALVD is contained within the LSI53C895A. The LSI53C895A connects directly to the SCSI bus and generates signal timing and bus protocol in compliance with the SCSI standard.

The SCSI interface on the LSIU80ALVD operates as an 8-bit or 16-bit interface. It supports 8-bit or 16-bit, synchronous and asynchronous, LVD or SE, Fast, Ultra and Ultra2 SCSI protocols in various combinations. The interface is made through connectors J2 and J3 (see Figure 2.1). Internal connector J2 is a 68-pin HD right angle latching connector. External connector J3 is a shielded 68-pin HD right angle connector that protrudes through the back panel bracket.

An on-board LED (labeled Activity) indicates SCSI bus activity. LVD/SE dual mode, active termination is provided on the LSIU80ALVD.

Termination is automatically disabled when both SCSI connectors are used.

The LSIU80ALVD supplies SCSI bus TERMPWR through a blocking diode and a self-resetting 1.5 A short circuit protection device.

A 40 MHz oscillator is installed on the LSIU80ALVD to provide the clock frequency to the LSI53C895A that is necessary to support Ultra2 SCSI transfers of up to 80 Mbytes/s.

1-4 Using the LSIU80ALVD

1.3.3 Ultra2 SCSI Technology

The LSIU80ALVD fully supports Ultra2 SCSI. Ultra2 SCSI is an extension of the SCSI Parallel Interface 2 and 3 (SPI-2 and SPI-3) family of standards that expands the bandwidth of the SCSI bus, allowing faster synchronous data transfers.

For the internal bus, special impedance SCSI ribbon cables are speciﬁed for operation with Ultra and Ultra2 SCSI devices. You must consider the total length of the bus cables and the number of devices on the SCSI bus when setting up your system.

Use SCSI cables that have been rated for standard SCSI (Fast, Ultra, and Ultra2) environments.

See Chapter 2, “Installing the LSIU80ALVD,” for a detailed explanation of SCSI bus connections.

1.3.4 LVDlink Technology

To support greater device connectivity and a longer SCSI cable, the LSIU80ALVD features LVDlink technology, the LSI Logic implementation of Universal LVD SCSI. LVDlink transceivers provide the inherent reliability of differential SCSI, and a long-term migration path to faster SCSI transfer rates.

The LVDlink transceivers reduce the power needed to drive the SCSI bus, so that the I/O drivers can be integrated directly into the chip. LVDlink technology lowers the amplitude of noise reﬂections and allows higher transmission frequencies.

The LVDlink transceivers operate in LVD and SE modes. They also allow the chip to detect a High Voltage Differential (HVD) signal when the chip is mistakenly connected to external HVD transceivers. The LSI53C895A automatically detects which type of signal is connected, based on the voltage detected, and automatically switches as needed to the SE or LVD mode. All bus devices must be LVD or SE. If a HVD device is detected, the board puts the SCSI bus in the high impedance state and shuts down.

Interface Descriptions 1-5

1.3.4.1 Beneﬁts of LVDlink

The LSI53C895A supports LVD for SCSI, which is a signaling technology that increases the reliability of SCSI data transfers over longer distances than supported by SE SCSI. The low current output of LVD allows the I/O transceivers to be integrated directly into the chip. LVD provides the reliability of HVD SCSI without the added cost of external differential transceivers. Ultra2 SCSI with LVD allows a longer SCSI cable and more devices on the bus, using the same cables deﬁned in the SCSI-3 parallel Interface (SPI-2) standard for Ultra SCSI.

Important: To utilize Ultra2 SCSI performance, the user must only

Chapter 2 Installing the LSIU80ALVD

This chapter provides instructions on how to install the LSIU80ALVD 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, “Completing the Installation,” page 2-24

2.1 Quick Installation Procedure

This section is provided for the experienced computer user with prior host adapter installation and SCSI bus setup experience. If you prefer a more detailed guidance for installing the LSIU80ALVD, follow the instructions in the Section 2.2, “Detailed Installation Procedure.”

For safe and proper installation, check the user’s manual supplied with your computer and perform the following steps.

Step 1. Ground yourself before removing this host adapter board.

Remove the LSIU80ALVD 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; do not touch board components or gold connector contacts. The use of a static ground strap is recommended.

LSIU80ALVD PCI to Ultra2 SCSI Host Adapter 2-1

Step 4. Locate the slots for installing a PCI plug-in board. The

LSIU80ALVD requires a PCI slot that allows bus master

operation. See Table 2.2. Step 5. Remove the blank bracket panel on the back of the computer

aligned with the PCI slot you intend to use. Save the bracket

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

the PCI slot. Make sure the edge connector is properly aligned

before pressing the board into place. See Figure 2.2.

Note: You may notice that the components on a PCI host adapter

face the opposite way from non-PCI adapter 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 (see Figure 2.1) should ﬁt

where the blank bracket panel was removed. Secure the

bracket with the bracket screw before making the internal and

external SCSI bus connections. 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 (see Figure 2.1). Make certain to match pin 1 on

both connectors. Step 9. Connect the LED cable if desired. This is designed to drive an

off-board system LED and indicates activity on the SCSI bus.

The off-board LED will operate at the same time as the

on-board SCSI Activity LED. Step 10. Replace the cabinet cover as described in the user’s manual for

your computer. Step 11. Make all external SCSI bus connections. Finally, refer to the

PCI Storage Device Management System SDMS 4.0 User’s

Guide (or the guide for the software you will use) to load the

driver software for your particular operating system. Remember: The SCSI bus requires proper termination, and no duplicate

SCSI IDs.

Figure 2.7 Multiple Internal SCSI Devices Chained Together

Detailed Installation Procedure 2-13

Most PC cabinets are designed with a front panel LED. You may connect the LED cable to connector J4 on the host adapter, as shown in

Figure 2.8. This causes the front panel LED to light when there is activity

on the SCSI bus. Connector J4 is not keyed. The orientation of the LED cable does not

matter as long as all four pins are connected.

Figure 2.8 SCSI LED Connector

LED Connector J4

Some LED cables have only two wires. In this case, place the connector on one end or the other of J4. If the LED does not light during SCSI bus activity from this host adapter, you may have to rotate the LED cable connector 180° on J4.

Detailed Installation Procedure 2-17

2.2.6 SCSI Bus Termination

The devices making 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 have their terminators active. All other SCSI devices on the bus must have their terminators removed or disabled. Remember that the LSIU80ALVD is also on the SCSI bus—its termination is automatically enabled when it is connected to the end of the bus.

Important: To utilize Ultra2 SCSI performance, theuser must only have

LVD devices on the bus. Do not mix any SE devices with LVD devices as the entire bus will drop to SE with maximum Ultra SCSI performance.

The peripheral device terminators are usually set with jumpers, resistor modules, or with a switch on the peripheral. Refer to the peripheral manufacturer’s instructions and to the user’s manual for your computer for information on how to identify the terminator setting of each device and how to change it.

Caution: The autoenable/disable sensing feature on the

LSIU80ALVD may enable termination erroneously if it is directly cabled to another SCSI device or host adapter using the same sensing method. The LSIU80ALVD senses the presence of SCSI devices by detecting the ground signal on conductor 50 of the SCSI cable.

The LSIU80ALVD automatically controls SCSI bus termination for three different bus conﬁgurations, depending on the use of connectors (see

Figure 2.1). The three bus conﬁgurations are:

• Only for internal SCSI connections,

• Only for an external SCSI connection, and

• Connections to both internal and external SCSI connectors.

Termination on the LSIU80ALVD for these three different bus conﬁgurations is discussed below.

2-18 Installing the LSIU80ALVD

2.2.7 Internal Bus Connections

If you have only internal SCSI device connections to your host adapter, you must terminate the last internal device on the SCSI bus. You must disable the terminators on all other devices. Termination on your host adapter is automatically enabled in this case.

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

SCSI bus conﬁguration.

2.2.8 External Bus Connections

If you have only external SCSI device connections to your host adapter, you must terminate the last external device on the SCSI bus. You must disable the terminators on all other devices. Termination on the host adapter is automatically enabled in this case.

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

Detailed Installation Procedure 2-21

2.2.10 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI ID 0 through 15. 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 SCSI hard disk drive on the SCSI bus, that drive should have the lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for system performance optimization, an ID other than 0 (zero) can be used.

Chapter 3, “Conﬁguring the LSIU80ALVD,” 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.

Step 1. Determine the SCSI ID of each device on the SCSI bus. Note

Step 2. Make any necessary changes to the SCSI IDs to eliminate

any duplications.

Chapter 3 Conﬁguring the LSIU80ALVD

This chapter describes conﬁguring the LSIU80ALVD and includes these topics:

• Section 3.1, “When to Conﬁgure the LSIU80ALVD,” 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 LSIU80ALVD

In most cases you should not need to change the default conﬁguration of the 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 affect the 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 LSI Logic SCSI BIOS Version 4.XX, and it includes the LSI Logic SCSI BIOS Conﬁguration Utility, you can change the default conﬁguration of the 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 LSI Logic 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.

3-2 Conﬁguring the LSIU80ALVD

NonVolatile Random Access Memory (NVRAM) is available on the LSIU80ALVD. Changes can be made and stored using this menu driven utility.

Important: This utility is a powerfultool. 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.

Note: 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. 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 4.0 and above supports the SCSI Plug and Play protocol called SCAM. SCAM support by default is off in versions 4.09.00 and later for the LSI53C895A device. You may choose to turn this 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.

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.

3-8 Conﬁguring the LSIU80ALVD

Host SCSI ID – This option refers to the host adapter’s SCSI ID, which is a unique number used to identify the device on the SCSI bus.

Note: 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

• Boot Drive Only

• With Media Installed

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.

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

Starting the SCSI BIOS Conﬁguration Utility 3-9

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 non-compatible systems, there is another option that can be selected by choosing CHS Mapping and then moving the cursor 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

3.2.3, “Device Selections Menu,” below.

• 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 when using either the Format utility or the FDISK/MBR command that you target the correct disk.

After clearing the partitions and data, it is necessary to reboot and clear memory or the old partitioning data will be reused.

Spinup Delay (seconds) – This option allows the user to stagger spinups 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 spinups to limit startup 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. 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 Autotermination. The alternate value is Off.

Sync Rate (Mbytes/s) – This option deﬁnes the maximum data transfer rate the host adapter will attempt to negotiate. The host adapter and a SCSI device must agree to a rate they can both handle.

Width (bits) – This option deﬁnes the maximum SCSI data width the host adapter will attempt to negotiate. The host adapter and a SCSI device must agree to a width they can both handle. Only host adapters that can do 16-bit data transfers have this option enabled.

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

3-12 Conﬁguring the LSIU80ALVD

Read/Write I/O Time-Out (seconds) – This option 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 allowing the system to recover if an I/O operation fails, it is recommended that you always set the time-out to a value greater than zero.

Note: If the time-out is set to zero, then the I/O will never time-out.

Scan for Device at Boot Time – Set this option to No when there is a device you do not want to be 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.

Scan for SCSI Logical Units (LUNs) – Set this option to No if you have problems with a device that responds to all LUNs whether they are occupied or not. For example, if there is a SCSI device with multiple LUNs but you do not want all of those LUNs to be available to the system, then set this option to No. This will limit the scan to LUN 0 only.

Queue Tags – This option allows the user to enable or disable the issuing of queue tags during I/O requests when your device driver can do this.

Initial Boot – This option allows any device attached to the ﬁrst adapter to become the boot device. It provides the users of non-BBS personal computers some of the ﬂexibility of a BBS machine.

Format – If enabled, this option allows you to low-level format a magnetic disk drive. Low-level formatting will completely and irreversibly erase all data on the drive. Note that this utility will only format 512 byte sectors. For other sector sizes, do not use this utility.

Verify – This option allows you to read all the sectors on a disk looking for errors. When selected, this option displays the following message:

Verify all sectors on the device Press ESC to abort Else press any key to continue

Help – This option displays a help screen with information about the current menu.

Restore Default Setup – This option resets all device selections back to their optimal settings. Select this option to restore all manufacturing defaults for the speciﬁed adapter. Note that all user customized options will be lost upon saving after restoring default setup.

Exit this menu – This option allows the user to leave the current menu screen and return to the previous screen.

3.3 Exiting the SCSI BIOS Conﬁguration Utility

Since some changes only take effect after the system reboots, it is important that you exit from this Conﬁguration Utility properly. Return to the Main Menu and exit by using the Quit option.

Important: Rebooting the system without properly exiting from this

utility may cause some changes to not take effect.
