Introduction
Drivers and Backup Software
Drivers
Check your operating system documentation to see whether a driver for DDS
drives is provided. If no operating system driver is available, you can use
various software applications to connect DDS drives.
Even operating systems which do support DDS drives directly only provide a
very basic level of support, so it is still a good idea to use software
applications to provide friendly user interfaces and to make full use of DDS
features.
UNIX Applications
You can write scripts to control DDS drives in UNIX using standard backup
utilities such as cpio and tar. To achieve more sophisticated control of the
drives, and to exploit the full range of DDS features, it is worth considering
software applications specifically designed for the task.
Application Software Availability
Most backup software companies provide applications for HP DDS products.
Contact your software supplier for details. Alternatively, contact your HP
supplier, who can provide you with details of a wide range of compatible
software.
For details of software for autoloaders, please contact your support center.

8Introduction
Configuring a Drive
When the drive is powered on, it reads a set of configuration switches on the
underside of the drive (see Chapter 9, “Introduction to Configuration
Switches”).
To change the configuration:
1 Switch the drive off.
2 Select the correct configuration for your system. See “Configuration
Switches” on page 41 for details of which setting to use for your system.
3 Switch the drive on again.
4 Ensure that the appropriate drivers and application software are installed
on the host computer.
Introduction 9
Introduction
Configuring an Autoloader
Note Autoloaders only exist in DDS-3 and DDS-4 versions, not
DAT 72.
Figure 1 Internal autoloaders: option switches
To configure an autoloader:
Note See “Autoloader Option Switch Settings” on page 51 for details
of the settings you need for different systems.
1 Switch the autoloader off.
2 Set the drive configuration on the switches on the underside.
10 Introduction
3 Set the autoloader configuration as follows:
Internal built-in autoloaders: set the switches on the rear of the autoloader
mechanism (see Figure 1).
External standalone autoloaders: the value of the option switch settings is
the number on the right when looking at the rear of the autoloader. To
change the number, click on the little buttons marked ‘−’ and ‘+’ above
and below the number with a ball-point pen or similar.
4 Switch the autoloader on again.
5 Ensure that the appropriate drivers and application software are installed
on the host computer.
