The following operands are supported: major The major device number. minor The minor device number; can be either decimal or octal. The assignment of major device numbers is specific to each system. You must be the super-user to use this form of the command. name A special file to be created. USAGE

ftp(1), in.ftpd(1M), mknod(2), symlink(2), attributes(5), largefile(5) NOTES
If mknod(2) is used to create a device, the major and minor device numbers are always interpreted by the kernel running on that machine. With the advent of physical device naming, it would be preferable to create a symbolic link to the physical name of the device (in the /devices subtree) rather than using mknod.
