Generic SCSI Device Special Files

Generic SCSI Device Special Files

The creation and use of device special files is discussed under "Device Special Files". A device special file represents a device, and is the mechanism for associating a device with a kernel-level device driver.

The device special files in the /dev/scsi directory are all associated with the dsreq driver. A basic set of these names is created automatically by the /dev/MAKEDEV script (see "The Script MAKEDEV"). You have to create additional device special files if you need to control logical units other than logical unit 0.
