How to Configure a Device Node to Use a Tape Device Effectively on Unix Systems

摘要

The present invention relates to an apparatus and method for efficiently using a tape device in a UNIX system in which a tape device can be used more efficiently by reconfiguring node names and minor numbers of various types of tape devices in a UNIX system to set the operation mode and recording density of the tape device And includes a major number indicating the type of the device, a location in each UNIX system of the device, and a minor number representing the property of the device, and is displayed to the user as the name of the device node Wherein the name of the device node is represented by a major number and a minor number in the UNIX system, wherein the name of the device node is a device directory in which each device node is located and exists separately for each device type; A recording density display unit of the apparatus; A variable block size mode setting display unit, and a device type display unit, wherein the minor number further comprises a field for setting the recording density field and variable block size mode, The recording density display field and the recording density field of the minor number differ according to the type of apparatus and the recording format.
