System Administration Commands devfsadm(8)
NAME
devfsadm, devfsadmd - administration command for /dev
SYNOPSIS
/usr/sbin/devfsadm [-C] [-c device_class] [-i driver_name]
[ -n] [-r root_dir] [-s] [-t table_file] [-u] [-v]
/usr/lib/devfsadm/devfsadmd
DESCRIPTION
devfsadm maintains the /dev namespace. It replaces the previous suite
of devfs administration tools including drvconfig(8), disks(8),
tapes(8), ports(8), audlinks(8), and devlinks(8).
The default operation is to attempt to load every driver in the system
and attach to all possible device instances. Next, devfsadm creates
logical links to device nodes in /dev and /devices and loads the device
policy.
devfsadmd(8) is the daemon version of devfsadm(8). The daemon is
started during system startup and is responsible for handling both
reconfiguration boot processing and updating /dev and /devices in
response to dynamic reconfiguration event notifications from the ker‐
nel.
For compatibility purposes, drvconfig(8), disks(8), tapes(8), ports(8),
audlinks(8), and devlinks(8) are implemented as links to devfsadm.
In addition to managing /dev, devfsadm also maintains the
path_to_inst(5) database.
OPTIONS
The following options are supported:
-C
Cleanup mode. Prompt devfsadm to cleanup dangling /dev links that
are not normally removed. If the -c option is also used, devfsadm
only cleans up for the listed devices' classes.
-c device_class
Restrict operations to devices of class device_class. Solaris
defines the following values for device_class: disk, tape, port,
audio, and pseudo. This option might be specified more than once to
specify multiple device classes.
-i driver_name
Configure only the devices for the named driver, driver_name.
-n
Do not attempt to load drivers or add new nodes to the kernel
device tree.
-s
Suppress any changes to /dev. This is useful with the -v option for
debugging.
-t table_file
Read an alternate devlink.tab file. devfsadm normally reads
/etc/devlink.tab.
-u
Activate and attach devices for drivers added with add_drv(8) -u.
Cannot be used together with -n or -r.
-r root_dir
Presume that the /dev directory trees are found under root_dir, not
directly under root (/). No other use or assumptions are made about
root_dir.
-v
Print changes to /dev in verbose mode.
EXIT STATUS
The following exit values are returned:
0
Successful completion.
1
An error occurred.

NOTES
This document does not constitute an API. The /devices directory might
not exist or might have different contents or interpretations in a
future release. The existence of this notice does not imply that any
other documentation that lacks this notice constitutes an API.
devfsadm no longer manages the /devices name space. See devfs(4FS).
As a daemon to support hot-plug and synchronous device naming, devfsadm
is managed by the service management facility, smf(7), under the ser‐
vice identifier:
svc:/system/devfsadm:default
The status of the service can be queried using the svcs(1) command.
