MKNOD(8) BSD System Manager's Manual MKNOD(8)NAME
mknod -- make device special file
SYNOPSIS
mknod [-F format] name [c | b] major minor
mknod [-F format] name [c | b] major unit subunit
mknod name [c | b] number
mknod name w
DESCRIPTION
The mknod command creates device special files.
To make nodes manually, the required arguments are:
name Device name, for example ``sd'' for a SCSI disk on an HP300 or a ``pty'' for pseudo-devices.
b | c | w
Type of device. If the device is a block type device such as a tape or disk drive which needs both cooked and raw special files, the
type is b. Whiteout nodes are type w. All other devices are character type devices, such as terminal and pseudo devices, and are
type c.
major The major device number is an integer number which tells the kernel which device driver entry point to use.
minor The minor device number tells the kernel which one of several similar devices the node corresponds to; for example, it may be a spe-
cific serial port or pty.
unit and subunit
The unit and subunit numbers select a subset of a device; for example, the unit may specify a particular SCSI disk, and the subunit a
partition on that disk. (Currently this form of specification is only supported by the bsdos format, for compatibility with the
BSD/OS mknod(8).)
Device numbers for different operating systems may be packed in a different format. To create device nodes that may be used by such an oper-
ating system (e.g. in an exported file system used for netbooting), the -F option is used. The following formats are recognized: native,
386bsd, 4bsd, bsdos, freebsd, hpux, isc, linux, netbsd, osf1, sco, solaris, sunos, svr3, svr4 and ultrix.
Alternatively, a single opaque device number may be specified.

A mknod command appeared in Version 6 AT&T UNIX. The -F option appeared in NetBSD 1.4.
NetBSD 1.4 September 11, 1998 NetBSD 1.4

mknod.h - header file of macros for handling device numbers
SYNOPSIS DESCRIPTION
The header file defines macros to create and interpret device identification numbers for use with the system call (see mknod(2)).
The use of these macros is architecture-dependent. See the System Administration Manual for your system for information on how to select
major and minor device numbers.
contains the macro
which packs the major and minor components into a device identification number suitable for the dev argument of and the two macros:
which extract the major and minor number components, respectively, from a device identification number, dev.
The macro is a specification (see printf(3S)) that prints the minor number in the format best suited to the particular implementation; it
is used by the long format of the command (see ls(1)) to show the minor numbers for device files.
The base of the number is indicated in the same way as in the C programming language: no leading zero for decimal, leading zero for octal,
and leading for hexadecimal.

Good evening ...
does anyone of you know how to change major/minor numbers of disk devices ?
