The Purpose of this Manual

This manual provides basic information on configuring the drives with various operating systems.

Please see the top-level release notes that accompany the drive for expected functionality and features.

Ultrium drives are supported on the following platforms:

• HP UNIX systems (HP-UX) (Chapter 2)

• HP Alpha UNIX (Chapter 3)

• IBM (AIX) (Chapter 4)

• Linux (Chapter 5)

• Sun Systems, S o laris 8, 9, 10 ( Chapter 6)

For platforms not mentioned here, please contact HP because there may be new connectivity details available that arrived after the release notes were published.

See Chapter 7 for details of how to verify the installation.

Ultrium Drives in a Library

Ultrium drives may also be used in a library. However, instructions about installing device drivers for automatic robotics are not included in this manual.

Backup Applications

For optimum performance it is important to use a backup application that supports the drive’s features within your system’s configuration. Please see the “Getting Started Guide” for more information about usage models.
