AIT Drive Reference Guide xi

The Compaq AIT tape drive is a high-capacity data storage device that uses AIT (Advanced Intel ligent Tape) technology. The tape drive provides low-cost, reliable data protection for entry-level servers, workstations, and desktop computers. With a backup software application it can provide up to a 2:1 data storage compression ratio. The AIT tape drive is shipped from the factory with data compression enabled; see Appendix D for more information on changing this setting.

Requirements

Compaq recommends equip pin g the compu ter wit h a 3 2-bit Fa st SCSI- 2 Control ler o r higher . An y of these contro llers fu lly support s the AIT tape dri ve . Install the control ler before beginning the drive installation, using the documentation included with the controller.

IMPORTANT:

or in an external storage device, but not both. The exception is a CD-ROM drive, which may be internal when other devices are external or vice versa.

NOTE:

All SCSI devices on the same bus must either be internal (within the computer)

This requirement does not apply to the AIT 35 ID E tape dri ve.

Device Drivers

Drivers for SCSI controllers are located on the Support Software Diskettes and on the Compaq SmartStart for Servers CD. Tape device driver location depends on the operating system and third-party software that is being used. The Compaq Native Drivers CD contains generic drivers for Microsoft-related server products. You can also download SCSI and tape drivers from the Compaq website at The drivers on downloaded Support Software Diskettes may be newer versions with new functionality and upgraded utilities.

Installing the Software Drivers

Installing the Software Drivers

Driv ers for the SCSI cont roller s are located on the Com paq SmartStar t for Serv ers CD and Support Software Diskettes. Smart Start ships with each computer. Support Software can be downloaded from the Compaq website. The software tape device driver is located either with your tape backup software or with the operating system. Compaq does not provide a .CDM tape driver for native NetWare support.

• Refer to your backup application installation guide for more information

regarding additional software that might be needed.

•Run the readme.com file on any of the Novell Software Support Diskettes (NSSD)

for driver installat ion instructions.

• Be sure to load the drivers in accordance with the Compaq co ntroller being used. There are additional driver issues if you wish to use applications requiring the

Advanced SCSI Programming Interface (ASPI) support. For more information, see the following section.

Installing the Software Drivers

NetWare ASPI Support

The Readme.com on the Novell Software Support Diskette (NSSD) outlines the specific drivers you need to support ASPI tape backup applications.

NWASPI is used by some third pa rty softw are v endors such as Veritas Backup Exec in versions prior to BackupExec for Netware Version 9.0. After 9.0 NWASPI will be replaced by the Veritas driver BECDM.CDM. This driver is loaded automatically when you start the backup a ppl ication. If you are using NWASPI you can load it from the C:\nwserver\drivers directory. It is recommended that you download and use the latest NWASPI driver from the Novell websit e.

Refer your third party vendor documentation for specific details regarding how tape drivers are loaded.

Compaq Tru64 UNIX

The Compaq Tru64 UNIX operating system uses Dynamic Device Recognition (DDR), which allows the operating system to recognize the AIT drive without a software tape device driver.

If the following message is seen on any version of Compaq Tru64 UNIX, you should update the DDR database to include the new device parameters.

ctape_ioctl: unmapped scsi density code (0x30)-DDR entry needed

The SCSI tape dri v e f or True64 UNIX provides a sta ndard t ape dr i ve interface. This is the tape driver for any Compaq SCSI tape device connected to a True64 UNIX operating system. Facilities are provided to allow the addition of SCSI tape drives to the system.

OpenVMS

The OpenVMS operating system uses Dynamic Device Recognition (DDR), which allows the operating system to recognize the AI T drive without a soft ware tape device driver.

SCO OpenServer

The drivers required to support the AIT tape drive under SCO OpenServer are:

• The SCO SCSI tape (stp) driver, which is built into SCO OpenServer; see the

SCO System A dministrator's Guide for information on configuring the driver.

Installing the Software Drivers

• An appropriate SCSI controller driver. Drivers for the SCSI controllers and tape drive hardware are located on the Support

Software Diskettes and on the Compaq SmartStart for Servers CD. The Support Software ships with each computer or can be downloaded from the Compaq website. The software tape device driver is located either with your tape backup software or with the operating system. Refer to your backup application installation guide for more information regarding additional software that might be needed.

Refer to the appropriate readme file on the Support Software Diskettes. The required driver is CHA.

In addition, the appropriate version of the Compaq Extended Feature Supplement (EFS) for SCO OpenServer is required:

NOTE:

EFS for SCO OpenServer is available on the Compaq SmartStart for Servers CD and is installed and configured automatically during a SmartStart installation.

AIT Drive Reference Guide 2–5

For SCO OpenServer 5, use Compaq EFS version 5.26 or higher.
