This chapter describes the IBM AIX Enhanced Tape and Medium Changer Device
Driver (Atape) for IBM tape devices.
For tape diagnostic and utility functions refer to Chapter 10, “IBM Tape Diagnostic
Tool (ITDT),” on page 259 or “AIX System - Tape Utility Program (tapeutil)” on
page 362.
Purpose
The IBM AIX Enhanced Tape and Medium Changer Device Driver is designed
specifically to take advantage of the features provided by the IBM tape drives and
medium changer devices. The goal is to give applications access to the functions
required for basic tape operations (such as backup and restore) and medium
changer operations (such as mount and demount the cartridges), as well as to the
advanced functions needed by full tape management systems. Whenever possible,
the driver is designed to take advantage of the device features transparent to the
application. Please note that some independent software vendor (ISV) applications
have certain device driver requirements. Before installing the device drivers, please
refer to the ISV web site or their support to find out what device drivers should be
used for the ISV.
