makedev(1M)                                                     makedev(1M)


   NAME
         makedev - adds /dev entries for generic devices table

   SYNOPSIS
         /sbin/auto-device/makedev

   DESCRIPTION
         makedev performs the following steps:

         1.  Any generic device names in the /dev/SA and /dev/rSA directories
             are deleted.  For the reference port only, the AT&T-compatible
             device names in the /dev/dsk and /dev/rdsk directories are also
             deleted.

         2.  The /dev/dsk, /dev/rdsk, /dev/rmt directories are scanned for the
             controller-specific device names present (for example, m323* or
             m350*).  For each unique disk and tape found, its Extended EDT
             information is examined to determine if it is a hard disk,
             floppy, archive-compatable tape, or nine-track tape.

         3.  Generic device names for each device type [for example, hard disk
             (disk), archive (ctape), nine track (ninetrack)] will be assigned
             numbers (starting with 1) in the order that the devices were
             scanned if the file /etc/device-map is not found.  If this file
             is present, device numbers are assigned in the order that the
             controller-specific names are listed in the file.  Any devices
             found that are not specified in the file have their device
             numbers assigned in scanned order.

         4.  The generic names are created in the /dev/SA and /dev/rSA
             directories.  For the reference port only, AT&T-compatible disk
             names are created in /dev/dsk and /dev/rdsk by linking them to
             the controller-specific names.

         makedev is called each time the system is booted, but after all other
         device naming programs have been run.  It must also be called after
         sysadm rmdisk to restore the /dev entries so a disk can be
         repartitioned.

   FILES
         /dev/SA/* entries for the hard disks for use by system administration
         /dev/rSA/*
                   entries for the hard disks and tapes for use by system
                   administration
