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, /dev/rSA, /dev/term, /dev/rmt, /dev/printer directories are deleted. 

2.  The /dev/dsk, /dev/rdsk, /dev/rmt, and /dev/port directories are scanned for the controller-specific device names present (for example, m328_∗).  For each unique device found, its Extended EDT information is examined to determine if it is a hard disk, floppy, CDROM, archive-compatible tape, nine-track tape, serial port, or printer port. 

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, /dev/rSA, /dev/term, /dev/rmt, and /dev/printer directories. 

5.  The /etc/device.tab file is examined and modified if any entries refer to devices which no longer exist or if new devices must be added. 

makedev is called each time the system is automatically reconfigured, 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 resliced. 

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

/dev/rmt/∗ entries for the generic tape names

/dev/term/∗ entries for the generic port names

/dev/printer/∗ entries for the generic printern ames

/etc/device_map
forces a particular ordering when naming generic devices
