Purpose and Scope

This application note provides the information necessary to allow you to interface a Qualstar
SCSI tape drive to Hewlett Packard 9000 computers. This includes the Series 300/400, Series
600/800, and the Series 700 (Apollo).

2.

 

Overview

The HP9000 uses the HP-UX operating system. A working knowledge of the HP9000 and the
HP-UX operating system is assumed. If you need detailed information about these systems,
please refer to the appropriate Hewlett Packard manual. You may also wish to refer to one of
the following Qualstar User Guides for detailed information about configuring and using your
Qualstar tape drive:

 

Qualstar 1054 - Document 500100

 

Qualstar 1260S - Document 500250

 

Qualstar 34XXS - Document 500300

Installing a Qualstar tape drive on an HP9000 consists of the following steps:

1.

 

Connecting the tape drive to the HP9000.

2.

 

Configuring the tape drive to emulate an HP7980S tape device.

3.

 

Configuring the HP9000 using either the System Administration Manager (SAM) or the
HP-UX commands.

4.

 

Testing the installation.

3.

 

Connecting the Tape Drive to the HP9000

Qualstar SCSI nine-track, half-inch tape drives are configured as SCSI 

sequential access

devices

 and as such, are to be connected to the SCSI port of the HP 9000 System Processing

Unit (SPU).

The tape drive is shipped from the factory with internal terminators installed. This assumes
that you will connect the tape drive at one end of the SCSI cable rather than in the middle. If
you plan to connect the tape drive in the middle of the SCSI cable, you'll need to remove the
tape drive's internal SCSI terminators. Failure to do so may result in improper system
operation. If you choose to use external terminators on the tape drive instead of the supplied
internal termination, you must remove the internal SCSI terminators.
