dn_setup(8)
NAME
  dn_setup - Creates and maintains device name databases. (The -sanity_check
  option is provided for system administration.)

SYNOPSIS
  /sbin/dn_setup [option]

OPTIONS
  -sanity_check
      Verifies the consistency and currency of the device special files and
      the directory hierarchy. The message Passed is displayed if the check
      is successful.

      The -sanity_check option is the only option that a system administrator
      should use. Use the following options only under guidance of your
      technical support representative.

  -boot
      Runs at boot time to create all the default device special databases,
      files, and directories.

  -default
      Creates the required device special directories only.

  -default_config
      Creates the class and category databases only.

  The following options are for internal use only and are used for debugging.
  Using these options can cause unrecoverable errors and prevent your system
  from booting:

  -clean
      Deletes everything in the device special directory tree and re-creates
      the entire tree (including device special files).

  -init
      Removes all the default device special databases, files, and
      directories. The -init prompts you to run the following command, which
      recreates all the device special files.

      # /sbin/dsfmgr -K

DESCRIPTION
  The /sbin/dn_setup script runs automatically at system startup to create
  device special file names and is not normally used by administrators.
  However, you might see device-related error messages at the system console
  during system startup, indicating that the system is unable to assign
  device special file names. Following such errors, use the -sanity_check
  option to verify the device name database.

  If the -sanity_check option displays messages other than Passed, use the
  dsfmgr command to further diagnose and correct the problem.

  The /sbin/bcheckrc utility also verifies device special files during system
  startup. If /sbin/bcheckrc discovers any problems, it displays the
  following message at the console:

       bcheckrc: Device Naming failed initial check.
	   Run dsfmgr -v, and if no errors are
	   reported, exit or type CTRL-D to continue
	   booting normally.

RESTRICTIONS
  Other than the -sanity_check option, use the dn_setup command only under
  the guidance of your technical support representative. Otherwise, you might
  alter critical system databases and prevent the system from booting. Such
  database problems might not be recoverable, requiring a full restoration of
  the operating system from your backup.

EXAMPLES
  Typical use of the command is as follows:

       # /sbin/dn_setup -sanity_check
       Passed.
