1 Introduction
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.
LTO Ultrium drives are supported on the following platforms:
•HP (HP-UX) servers and workstations (Chapter 2)
•HP (OpenVMS) servers and workstations (Chapter 3)
•HP (Tru64 5.1x) servers and workstations (Chapter 4)
•IBM (AIX) servers and workstations (Chapter 6)
•Linux (kernel 2.6.x) servers and workstations (Chapter 5)
•Sun (Solaris 8, 9, 10) servers and workstations (Chapter 7)
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 8 on page 37 for details of how to verify the installation.
LTO Ultrium drives in a library
Although LTO Ultrium drives may also be used in a library, instructions about installing device drivers for automatic robotics are not included in this manual.
SAS drives
SAS drives are only supported on Redhat and SLES Linux.
Backup applications
For optimum performance it is important to use a backup application that supports the drive’s features within your system’s configuration.
For details of which backup applications are supported with your tape drive and system, visit the HP Tape Compatibility website:
http://www.hp.com/products1/storage/compatibility/tapebackup/index.html
Follow the “Software compatibility” link then click a tick in the appropriate matrix to drill down into detailed application support information.
See the Getting Started Guide for more information about usage models.

8 Introduction
2 HP (HP-UX) servers and workstations
This chapter covers:
•HP servers and workstations: HP-UX 11i v1 (11.11), 11i v2 (11.23)
•HP servers: HP-UX 11i v3 (11.31)
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-UX11i v3 and agile addressing
HP-UX11i 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-UX11i v3 retains support for the legacy dsf format as used in HP-UX11i v1 and 11i v2.
For more information about HP-UX releases including HP-UX11i 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. In many cases the drive will be the only device on a SCSI bus1 in which case the default SCSI ID setting of 3 is suitable. See the tape drive User Guide for details of how to alter the SCSI ID setting physically (usually accessible at the rear panel of the drive).
Scan the system to list the existing devices attached. From a shell window (hpterm/xterm), execute ioscan as follows:
For HP-UX 11i v1, 11i v2 and 11i v3 (legacy format)
Enter the command:
% /sbin/ioscan -f
The output should look similar to the following (which shows SCSI drives):

NOTE: If you are installing a SCSI drive onto a Storage Area Network (SAN), the fibre channel/SCSI router will also appear in the list of attached devices.
For a particular SCSI device in the ioscan listing, the SCSI bus ID and the drive’s SCSI ID and LUN ID can be decoded from the H/W path (hardware path)/ For example:
Class |
I |
H/W Path |
Driver |
S/W State |

The H/W path for this tape drive is “2/0/1.5.0”.
•The SCSI bus ID is “2/0/1” (including all the numbers separated by “/”). From the remaining “.5.0” portion:
•Tape drive SCSI ID = 5
•Tape drive SCSI LUN = 0
Fibre Channel drives have a slightly different format in ioscan output, similar to the following segment:

The lunpath hardware path for the above tape drive is “0/4/1/0.0x50060b0000b7f3c8.0x0”.
•The FC bus ID is “0/4/1/0” (including all the numbers separated by “/”). From the remaining “0x50060b0000b7f3c8.0x0” portion:

If your tape drive or autoloader does not appear in ioscan listing or is listed with H/W Type “UNKNOWN” you may need to install the appropriate drivers.
Use the ‘sam’ utility. Sam runs as a mouse driven GUI (Figure 1) on a system with full graphics capability, or as a console text-based interface (Figure 2). If you use the text-based interface, use the Tab and arrow keys to navigate, and the Return key to select.
