Using Device Files - HP J Class Owner's Manual

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 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 conven-
tions of your particular system. See "SCSI ID
and Device File Information for HP-UX 10.0 or
Later" 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 path-
name of your device file in the examples that follow. Refer to the Sys-
tem Administration Tasks manual for information on how to create a
device file.
