device_maps(4)

NAME

device_maps– maps allocatable devices to device special files

SYNOPSIS

/etc/security/device_maps

DESCRIPTION

The device_maps file maps each allocatable device to the set of device special files that are associated with the device.

This file is normally created using the mkdevdb(1M) command, run by the init.d(4) scripts during a system's initial bootload or when the system is booted with the -r (reconfigure) option. The mkdevdb command creates a set of entries for the system's audio and removable media devices.

The preferred method of modifying the device_maps file is to use the Device Administration dialog box of the Device Allocation Manager.

Each device is represented by a one-line entry of the form:

device-name : device-type : device-list

where

device-name: is the allocation name of the physical device. This must match the name given in the device's device_allocate(4) entry.
device-type: is the generic device type. This must match the type given for the device in the device_allocate(4) file.
device-list: is a list of device special files under /dev that are associated with the physical drive. This field contains device special file pathnames separated by white spaces, or a list generator enclosed in backquotes (“).

Lines in device_maps can end with a \ to continue an entry on the next line. Leading and trailing blanks are allowed in any of the fields.
