devfsadm(1M)                                              System Administration Commands                                              devfsadm(1M)

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] [-v]

       /usr/lib/devfsadm/devfsadmd

DESCRIPTION

       devfsadm(1M) maintains the /dev namespace. It replaces the previous suite of devfs administration tools including drvconfig(1M), disks(1M),
       tapes(1M), ports(1M), audlinks(1M), and devlinks(1M).

       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(1M)  is  the  daemon  version  of  devfsadm(1M). 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 kernel.

       For compatibility purposes, drvconfig(1M), disks(1M), tapes(1M), ports(1M), audlinks(1M), and devlinks(1M)  are  implemented  as  links  to
       devfsadm.

       In addition to managing /dev, devfsadm also maintains the path_to_inst(4) 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.

       -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(7FS).

       The device configuration service is managed by the service management facility, smf(5), under the service identifier:

       svc:/system/device/local:default

       Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed  using  svcadm(1M).  The  ser-
       vice's status can be queried using the svcs(1) command.
