HP LTO Ultrium 4 drives technical reference manual, volume 5: UNIX, Linux and OpenVMS configuration guide 9
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

.
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 bus
1
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):
