If the floppy driver is not configured, ioscan returns the follow-
ing message:
ioscan: Device driver scsifloppy is not in the kernel
If you receive this message, go the the section, “Configuring the
Floppy Driver” later in this chapter for information on adding
the scsifloppy driver to the HP-UX kernel configuration.
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 chapter assume that the SCSI ID of your floppy
drive is set to the factory default of SCSI ID 0, using the device file
/dev/rfloppy/c201d0s0. (The underlined 0 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 or later, 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 or Later” in Chapter 1 of this book.
If you set the SCSI address of your floppy drive to a value other than
0, 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 Ad-
ministration Tasks manual for information on how to create a device
file.
