HP (HP-UX) servers and workstations

This chapter covers:
• HP servers and workstations: HP-UX 1 1i v1 (1 1.1 1), 1 1i v2 (1 1.23)
• HP servers: HP-UX 1 1i v3 (1 1.31)
NOTE: Only SCSI tape drives and autoloaders are supported on HP-UX.

Introduction

Before you install your tape drive log on to the HP web site, www.hp.com, and download the latest
hardware enablement (HWE) patch bundle for your operating system. This ensures that you will
have the correct device driver for your tape drive.
System Administration Management (SAM) tools have evolved with ongoing HP-UX version releases.
As a result, the procedures for setting up with different HP-UX versions differ. They are described
separately in this chapter.
HP-UX1 1i v3 and agile addressing
HP-UX1 1i v3 introduces agile addressing of devices. Agile addressing uses a different format of the
device special file (dsf) to represent the tape drive—known as a persistent dsf. However HP-UX1 1i v3
retains support for the legacy dsf format as used in HP-UX1 1i v1 and 1 1i v2.
For more information about HP-UX releases including HP-UX1 1i v3 please refer to
www.docs.hp.com.

Determining a suitable SCSI ID

The tape drive SCSI ID setting must be unique for the SCSI bus to which the drive is attached. Often
the drive will be the only device on the bus
the drive's User Guide for details of how to physically alter the SCSI ID setting (usually accessible at
the rear panel of the drive).
Scan the system to list the existing devices attached. From a shell window (
as shown below:
ioscan
For HP-UX 1 1i v1, 1 1i v2 and 1 1i v3 (legacy format)
%
/sbin/ioscan –f
The output should look similar to the following:
