For tape diagnostic and utility functions refer to Chapter 10, "IBM Tape Diagnostic Tool (ITDT)," on page 259 or "Linux System - Tape Utility Program (IBMtapeutil)" on page 385. Purpose The lin_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. Data Flow The software described in this chapter covers the Linux Device Driver (lin_tape device driver) and the interface between the application and the tape device. © Copyright IBM Corp. 2007, 2009 93
