NAME
      devfsadm, devfsadmd - administration command  for  /dev  and
      /devices
 


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 and /devices namespaces.  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.
      devfsadm then creates device special files in  /devices  and
      logical links in /dev.
 
      devfsadmd(1M) is the daemon  version  of  devfsadm(1M).  The
      daemon  is  started  by  the  /etc/rc* scripts 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(1M),   disks(1M),
      tapes(1M),  ports(1M),  audlinks(1M),  and  devlinks(1M) are
      implemented as links to devfsadm.
 
      In addition to managing /dev  and  /devices,  devfsadm  also
      maintains the path_to_inst(4) database.
 


OPTIONS
      The following options are supported:
 
      -C    Cleanup mode. Prompts devfsadm to invoke cleanup  rou-
            tines that are not normally invoked to remove dangling
            logical links. If  -c  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  may
            be specified more than once to specify multiple device
            classes.
 
      -i driver_name

 Maintenance Commands                                 devfsadm(1M)
 
 
 
            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 or /devices. This is use-
            ful 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 and /devices 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 and /devices in verbose mode.
 
 EXIT STATUS
      The following exit values are returned:
 
      0     Successful completion.
 
      1     An error occurred.
