Using Device Files

Device files are special files that tell your system which pathway to use
through the system hardware when communicating with a specific device,
and tell what kind of device it is.
The examples in this section assume that the SCSI ID of your CD-ROM
drive is set to the factory default of SCSI ID 2, using the device file
/dev/dsk/c201d2s0. (The underlined 2 indicates the SCSI ID number.)
NOTICE: The device file name used in these examples is appropriate only for
systems running HP-UX 9.05. If you are using HP-UX 10.0, the device file
names will depend on the naming conventions of your particular system.
See "SCSI ID and Device File Information for HP-UX 10.0" in Chapter 1
of this book.
If you set the SCSI address of your CD-ROM drive to a value other than 2,
you must create a device file for it, then substitute the pathname of your
device file in the examples that follow. Refer to the System Administration
Tasks manual for information on how to create a device file.
