1 Installation and Setup

The HP Ultra3 Single Channel SCSI Host Bus Adapter enables you to connect up to 15 SCSI devices—such as hard disk drives, scanners, and CD-ROM drives—to HP Netservers with 32-bit or 64-bit PCI expansion slots. You can connect newer Ultra3 and Ultra2 SCSI devices to the two 68-pin Low Voltage Differential/Single-Ended (LVD/SE) connectors. You can also connect legacy SCSI devices to the 68-pin and 50-pin internal Single-Ended (SE) connectors.

Figure 1-1. HP Ultra3 Single Channel SCSI Host Bus Adapter

Although the HP Ultra3 SCSI Host Bus Adapter is a 64-bit PCI host bus adapter, it also works in a 32-bit PCI slot. When installed in a 32-bit PCI slot, the host bus adapter automatically runs in the slower 32-bit mode. This installation guide explains how to:

•Install the HP Ultra3 SCSI host bus adapter

•Set up SCSI devices

•Connect SCSI devices

Bus Segments on the HP Ultra3 SCSI Host Adapter

The HP Ultra3 SCSI host bus adapter features technology that ensures you get the best performance from your Ultra3 and Ultra2 SCSI devices by electronically isolating the primary LVD/SE segment from the secondary SE segment on the SCSI bus. This allows the HP Ultra3 SCSI host bus adapter to support newer Ultra3 and Ultra2 SCSI devices at speeds up to 160 MBytes/sec on the primary LVD/SE segment while at the same time supporting Ultra (legacy) devices at speeds up to 40 MBytes/sec on the secondary SE segment. The following figure shows the two SCSI segments.

Primary LVD/SE Segment

Secondary LVD/SE Segment

AIC-3860

AIC-7892

Figure 1-2. Primary and Secondary Bus Segments

NOTE If you attach Wide Ultra or Ultra SCSI devices to the LVD/SE connector(s), the data transfer rate for all attached Ultra3 and Ultra2 SCSI devices will drop to Ultra SCSI performance levels. However, if you attach only Ultra3 and Ultra2 SCSI devices to the LVD/SE connector(s), data will be transferred at the maximum possible rate (80 MBytes/sec for Ultra2 devices and 160 MBytes/sec for Ultra3 devices).

Installing the HP Ultra3 SCSI Host Bus Adapter

1.Discharge any static electricity build-up before handling the SCSI host bus adapter by touching a grounded metal object (like the exposed metal parts on the back of your HP Netserver).

WARNING Turn OFF power to the HP Netserver and disconnect the power cord.

2.After you turn off your HP Netserver and unplug the power cord, remove the cover from the Netserver.

32-bit PCI Slot

64-bit PCI Slot

Figure 1-3. 32-bit and 64-bit Expansion Slots

3.Locate an unused 64-bit PCI expansion slot and remove the expansion slot cover. If the HP Netserver does not have a 64-bit slot, you can install the host adapter in a 32-bit PCI slot. (The expansion slot must be compliant with PCI Rev. 2.1 or higher and must support Bus Mastering.)

Figure 1-4. Host Bus Adapter Installed in 64-bit Slot

HP Netservers may have vertical or horizontal expansion slots. Refer to your HP Netserver manual to locate the PCI slots.

NOTE Be careful when inserting the HP Ultra3 SCSI host bus adapter in a PCI slot. Some 32-bit slots will not accommodate it, and the host adapter may break if you force it into the slot.

4.Insert the HP Ultra3 SCSI host bus adapter into the PCI expansion slot; press down firmly until the host adapter clicks into place, then replace the slot cover screw. When installed properly, the host adapter should appear level with the expansion slot, as shown above.

Setting Up SCSI Devices

There are several things you may need to do to your SCSI devices before you connect them to the HP Ultra3 SCSI host bus adapter:

•Check the SCSI IDs

•Set the termination

•Connect the power cables.

Since setup can vary from device to device, always refer to the device’s documentation for specific instructions.

Below are some guidelines for setting SCSI IDs and termination on your devices.

Check the SCSI IDs

The HP Ultra3 SCSI host bus adapter and each device you connect to it must have a unique SCSI ID number ranging from 0 to 15. No two devices can have the same ID number. The HP Ultra3 SCSI host bus adapter is preset to SCSI ID 7 and should not be changed. If your HP Netserver will boot from a SCSI hard disk, make sure the SCSI ID of that hard disk is set to 0. (Most SCSI hard disks are preset to SCSI ID 0 at the factory.) The SCSI IDs for internal devices are usually set with jumpers; SCSI IDs for external devices are usually set with a switch on the back of the device.

Terminate the Ends

To ensure reliable communication on the SCSI bus, the device at the end of each cable, or the end of the cable itself, must have a terminator installed (or enabled). Terminators must be removed, or termination must be disabled, on devices between the ends of each cable.

Choosing SCSI Cables

The Ultra3 SCSI Host Adapter kit does not include cables. Any Ultra3 drives attached to HP Ultra3 host bus adapters inside a HP Netserver require the use of a special Ultra3 twisted pair cable. The HP Ultra3 cable upgrade kit part number is P3469A. These cables can be purchased from an authorized Hewlett-Packard reseller, or on HP Order Assistant (available on the Internet at http://netserver.hp.com/netserver/)

See Table 1-1 that follows to determine the correct cable for your HP Netserver and SCSI configuration.

Connecting SCSI Devices

You can connect up to 15 SCSI devices to the HP Ultra3 SCSI host bus adapter. Before connecting devices, be sure to review Setting Up SCSI Devices on

page 5.

Connecting the SCSI Host Adapter to the Common Tray

Connect internal Ultra3 and Ultra2 SCSI devices to the internal LVD/SE connector on the HP Ultra3 SCSI host bus adapter. To do this, see Table 1-1 to determine the correct cable for your HP Netserver. Follow these steps to connect the devices:

NOTE We recommend that you keep your Ultra3 and Ultra2 SCSI devices separate from your Ultra SCSI devices. This allows the newer Ultra3 and Ultra2 SCSI devices to transfer data at their maximum speed. (See Bus Segments on the HP Ultra3 SCSI Host Adapter on page 2.)

1.Use a terminated twisted-pair SCSI cable.

2.Plug the non-terminated end of the twisted-pair cable to the internal LVD/SE connector.

LVD SCSI Twisted-Pair Cable

Figure 1-5. LVD SCSI Twisted-Pair Cable

3.Plug the internal Ultra2 or Ultra3 SCSI devices to the other cable connectors, starting with the connector at the terminated end of the cable.

Terminated LVD SCSI Twisted-Pair Cable

Terminator

Figure 1-6. Common Tray Cable Connection

NOTE Internal Ultra2 and Ultra3 SCSI devices come from the factory with termination disabled and cannot be changed. Proper SCSI bus termination is provided by the terminator at the end of the LVD SCSI cable.

4.Connect a power cable from your HP Netserver’s internal power supply to each internal SCSI device.

Connecting the SCSI Host Adapter to a Hot-Plug Cage

1.Use the point-to-point twisted-pair cable.

2.Plug one end of the twisted-pair cable to the internal LVD/SE connector.

3.Plug the other end of the twisted-pair cable to the 68-pin connector on the hot-plug cage.

Point-to-Point LVD Twisted-Pair SCSI Cable

Figure 1-7. Hot-Plug Cage Cable Connections

Connecting Ultra/Fast Wide SCSI Devices

Connect internal Ultra/Fast Wide SCSI devices to the 68-pin internal SE Wide SCSI connector. To do this, use a flat 68-pin Wide SCSI cable. Follow these steps to connect the devices:

1.Plug one end of the cable to the Ultra/Fast Wide SCSI connector on the HP Ultra3 SCSI host bus adapter.

68-pin flat SCSI cable

Figure 1-8. Connecting Ultra/Fast Wide SCSI Devices

2.Plug the other end of the cable to a terminated Ultra/Fast Wide SCSI device.

3.If you have other Ultra/Fast Wide SCSI devices, attach them to the connectors between the two ends of the cable. Be sure these other devices are unterminated.

4.Connect a power cable from your HP Netserver’s internal power supply to each internal device.

Connecting Internal Ultra/Fast Narrow Devices

Connect internal Ultra/Fast Narrow SCSI devices that have standard 50-pin connectors to the 50-pin internal SE Narrow SCSI connector. To do this, use a 50-pin internal SCSI cable. Follow these steps to connect the devices:

1.Plug one end of the cable to the 50-pin internal SE Narrow SCSI connector on the HP Ultra3 SCSI host bus adapter.

50-pin SE Narrow SCSI cable

Figure 1-9. Connecting Ultra/Fast Narrow Devices

2.Plug the other end of the cable to a terminated Ultra/Fast Narrow SCSI device.

3.If you have other Ultra/Fast Narrow SCSI devices, attach them to the connectors between the two ends of the cable. Be sure these other devices are unterminated.

4.Connect a power cable from your HP Netserver’s internal power supply to each internal device.

Connecting External SCSI Devices

Connect external Ultra2 and Ultra3 SCSI devices to the 68-pin external LVD/ SE SCSI connector. Each external device will require a high density 68-pin external LVD SCSI cable.

NOTE We recommend that you connect only Ultra3 and Ultra2 SCSI devices to the external SCSI connector. If you also attach older Ultra SCSI devices, the data transfer speed of the Ultra3 and Ultra2 SCSI devices will drop to the speed of the older devices. (See Bus Segments on the HP Ultra3 SCSI Host Adapter on page 2.)

Follow these steps to connect the external devices:

1.Connect one end of the external LVD SCSI cable to the external LVD/SE connector on the HP Ultra3 SCSI host bus adapter.

2.Connect the other end of the external SCSI cable to a SCSI connector on the back of an external SCSI device. If you are installing only one external device, terminate the device and skip to Step 4.

3.Connect other external devices by cabling each device to the previous one, as shown below.

Figure 1-11. Terminating the Last External SCSI Device

4.Terminate only the device at the end of the chain. (Use of an external multi-mode SCSI terminator is required.)

5.Connect power cables to all external devices and to the HP Netserver.

HP Ultra3 SCSI Host Adapter Driver Software

NOTE To use the HP Ultra3 SCSI host bus adapter, driver software must be installed for your operating system.

Preloaded Ultra3 Drivers

If the HP Ultra3 SCSI host bus adapter was included as part of a HP Netserver you purchased, then the appropriate HP driver has already been pre-installed by HP and you do not need to install it.

Embedded Ultra3 Drivers

Some operating systems have embedded driver support for the HP Ultra3 SCSI host bus adapter. To determine if the host adapter is supported by the operating system you are using, read the operating system manual or contact the operating system vendor for information.

Troubleshooting

If you have any problems while installing the HP Ultra3 SCSI host bus adapter, check the following items first:

•Are all SCSI devices powered on?

•Are all SCSI cables and power cables properly connected?

•Does each device on the SCSI bus have a unique SCSI ID?

•Does the total SCSI cable length exceed the maximum allowable length? (The maximum cable length for the Ultra3 SCSI host adapter cannot exceed 12 meters.)

•Is the SCSI bus properly terminated?

If you are still unable to resolve a problem, contact HP Technical Support for help.

2 Configuration with SCSISelect

SCSI Bus Interface Definitions

•Host Adapter SCSI ID—(Default: 7) Sets the SCSI ID for the SCSI host bus adapter. The Ultra3 SCSI Host Bus Adapter is set at 7, which

gives it the highest priority on the SCSI bus. We recommend that you do not change this setting.

•SCSI Parity Checking—(Default: Enabled) When set to Enabled, verifies the accuracy of data transfer on the SCSI bus. Leave this setting enabled unless any SCSI device connected to the Ultra3 SCSI Host Bus Adapter does not support SCSI parity.

•Host Adapter SCSI Termination—(Default: Automatic) Determines the termination setting for the SCSI host bus adapter. The default setting for both the LVD/SE and SE connectors is Automatic, which allows the SCSI host bus adapter to adjust the termination as needed depending on the configuration of the connected SCSI devices. We recommend that you do not change this setting.

Boot Device Options

•Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot device. We recommend that you do not change the default setting.

•Boot LUN Number—(Default: 0) Specifies which LUN (Logical Unit Number) to boot from on your boot device. This setting is not valid unless Multiple LUN Support is Enabled (see “Advanced Configuration Options” on page 19).

SCSI Device Configuration

SCSI Device Configuration options can be set individually for each connected SCSI device.

NOTE To configure settings for a SCSI device, you must know its SCSI ID (see “Using SCSI Disk Utilities” on page 22).

•Sync Transfer Rate—(Default: 160) Determines the maximum synchronous data transfer rate that the SCSI host adapter supports. Use the maximum value of 160 MBytes/sec. If a device is not Ultra160, select the transfer rate of the device (80, 53, 40, ...).

•Initiate Wide Negotiation—(Default: Yes) When set to Yes, the SCSI host bus adapter attempts 16-bit data transfer (wide negotiation). When

set to No, the SCSI host bus adapter uses 8-bit data transfer unless the SCSI device requests wide negotiation.

NOTE Set Initiate Wide Negotiation to No if you are using an 8-bit SCSI device that hangs or exhibits other performance problems with 16-bit data transfer rate enabled.

•Enable Disconnection—(Default: Yes) When set to Yes, allows the SCSI device to disconnect from the SCSI bus. Leave the setting at Yes if two or more SCSI devices are connected to the SCSI host bus adapter. If only one SCSI device is connected, changing the setting to No results in slightly better performance.

•Send Start Unit Command—(Default: Yes) When set to Yes, the Start Unit Command is sent to the SCSI device at bootup.

The following three options have no effect when the SCSI host bus adapter BIOS is disabled. (The SCSI host bus adapter BIOS is normally enabled by default.)

•Enable Write Back Cache—(Default: N/C) Can be used to enable or disable the write-back cache on SCSI disk drives connected to the host adapter. Leave this option at its default setting of N/C (no change), which usually allows for optimum drive performance.

•BIOS Multiple LUN Support—(Default: No) Leave this setting at No if the device does not have multiple Logical Unit Numbers (LUNs). When set to Yes, the SCSI host bus adapter BIOS provides boot support for a SCSI device with multiple LUNs (for example, a CD “juke box” device in which multiple CDs can be accessed simultaneously).

•Include in BIOS Scan—(Default: Yes) When set to Yes, the SCSI host bus adapter BIOS includes the device as part of its BIOS scan at bootup.

Advanced Configuration Options

NOTE Do not change the Advanced Configuration Options unless absolutely necessary.

•Reset SCSI Bus at IC Initialization—(Default: Enabled) When set to

Enabled, the SCSI host bus adapter generates a SCSI bus reset during its power-on initialization and after a hard reset.

•Display <Ctrl> <A> Messages during BIOS Initialization—(Default:

Enabled) When set to Enabled, the SCSI host bus adapter BIOS displays the Press <Ctrl> <A> for SCSISelect (TM) Utility! message on your screen during system bootup. If this setting is disabled, you can still invoke the SCSISelect Utility by pressing <Ctrl> <A> after the SCSI host bus adapter BIOS banner appears.

•Extended BIOS Translation for DOS Drives > 1 GByte—(Default:

Enabled) When set to Enabled, provides an extended translation scheme for SCSI hard disks with capacities greater than 1 GByte. This setting is necessary only for MS-DOS 5.0 or above; it is not required for other operating systems, such as NetWare or UNIX.

CAUTION Changing the translation scheme destroys all data on the drive. Be sure to back up the data before changing the translation scheme.

Use the MS-DOS Fdisk command to partition a disk larger than 1 GByte controlled by the SCSI host bus adapter BIOS, when using DOS, Windows 3.1.x, or Windows 95/98.

•Verbose/Silent Mode—(Default: Verbose) When set Verbose, the SCSI host bus adapter BIOS displays the host adapter model on the screen during system bootup. When set to Silent, the message will not be displayed during bootup.

•Host Adapter BIOS (Configuration Utility Reserves BIOS Space)—

(Default: Enabled) Enables or disables the SCSI host bus adapter BIOS.

Leave at Enabled to allow the SCSI host bus adapter BIOS to scan and initialize all SCSI devices.

Set to Disabled: Not scan if the devices on the SCSI bus (for

example, CD-ROM drives) are controlled by software drivers and do not need the BIOS, and you do not want the BIOS to scan the SCSI bus.

Set to Disabled: Scan Bus if you do not need the BIOS, but you want it to scan the SCSI devices on the bus.

The following four options have no effect when the SCSI host bus adapter BIOS is disabled. (The SCSI host bus adapter BIOS is normally enabled by default.)

•Domain Validation—(Default: Enabled) Determines the kinds of SCSI devices connected and reduces data transfer speed when legacy SCSI devices are detected. Displays the resulting data transfer rate.

•Support Removable Disks Under BIOS as Fixed Disks—(Default:

Disabled) Determines which removable-media drives are supported by the SCSI host bus adapter BIOS. Choices are as follows:

Disabled— No removable-media drives are treated as hard disk drives. Software drivers are required because the drives are not controlled by the BIOS.

CAUTION You may lose data if you remove a removable-media cartridge from a SCSI drive controlled by the SCSI host bus adapter BIOS while the drive is on. If you want to be able to remove the media while the drive is on, install the removable-media software driver and set Support Removable Disks Under BIOS as Fixed Disks to

Disabled.

Boot Only—Only the removable-media drive designated as the boot device is treated as a hard disk drive.

All Disks—All removable-media drives supported by the BIOS are treated as hard disk drives.

•BIOS Support for Bootable CD-ROMs—(Default: Enabled) When set to Enabled, the SCSI host bus adapter BIOS allows the computer to boot from a CD-ROM drive.

•BIOS Support for Int 13 Extensions—(Default: Enabled) When set to

Enabled, the SCSI host bus adapter BIOS supports Int 13h extensions as required by Plug-and-Play. The setting can be either enabled or disabled if your system is not Plug-and-Play.

Using SCSI Disk Utilities

To access the SCSI disk utilities, follow these steps:

1.Select the SCSI Disk Utilities option from the menu that appears after starting SCSISelect. SCSISelect scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the devices assigned to each ID.

2.Use the arrow keys to move the cursor to a specific ID and device, then press

Enter.

3.A small menu appears, displaying the options Format Disk and Verify Disk Media.

Format Disk—Allows you to perform a low-level format on a hard disk drive. Most SCSI disk devices are preformatted at the factory and do not need to be formatted again.

CAUTION A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. You cannot abort a low-level format once it has started.

Verify Disk Media—Allows you to scan the media of a hard disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select yes, those blocks are no longer used. Pressing Esc at any time aborts the utility.
