1Introduction
Purpose of this manual
This manual provides basic information on configuring the drives with various operating systems.
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, Solaris 8, 9, 10 (Chapter 6)
For platforms not mentioned here, 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
Although Ultrium drives may also be used in a library, 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. See the Getting Started Guide for more information
about usage models.
The following applications are suitable for use within an Enterprise environment and have been
tested with Ultrium drives. They use the operating system’s standard, built-in device drivers, as
described in this manual. For further information about optimizing performance and making full use
of the drive’s functions, contact the software manufacturer or HP.

HP servers and workstations—HP-UX 11.x
NOTE: HP-UX 10.x is only supported by Generation 1 Ultrium drives.
Introduction
Before you install your tape drive log on to the HP web site, www.hp.com, and download the latest
hardware enablement patch bundle for your operating system. This ensures that you will have the
correct device driver for your tape drive.
Determining attached devices
After you have installed the new tape drive, you can check it has been attached successfully. From a
shell window (hpterm/xterm), execute ioscan to display the list of attached devices.
# /sbin/ioscan -C tape -fn
The output should look similar to the following:

NOTE: If you are installing the drive onto a Storage Area Network (SAN), the fibre channel/SCSI
bridge will also appear in the list of attached devices.
Adding stape and schgr (autoloader driver) to the kernel using sam
Run the `sam` utility from the command line. Sam runs as a mouse driven GUI (fig. 1) on a system
with full graphics capability, or as a console text-based interface (fig. 2). If using the text-based
interface, use the tab and arrow keys to navigate, and the return key to select.
