This chapter discusses 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.
Basic tasks for Tape Drives are shown in the following table. Other topics discussed in this chapter are:
