System Management Guide: Operating System and Devices

Chapter 21. Tape Drives

This chapter covers system management functions related to tape drives. Many of these functions change or get information from the device configuration database, which contains information about the devices on your system. The device configuration database consists of the predefined configuration database, which contains information about all possible types of devices supported on the system, and the customized configuration database, which contains information about the particular devices currently on the system. For the operating system to make use of a tape drive, or any other device, the device must be defined in the customized configuration database and must have a device type defined in the predefined configuration database.

See the AIX Version 4.3 System Management Concepts: Operating System and Devices for the following related topics:
