 lssf(1M)                                                           lssf(1M)

 NAME    [Toc]    [Back]
      lssf - list a special file

 SYNOPSIS    [Toc]    [Back]
      /sbin/lssf special_file ...

 DESCRIPTION    [Toc]    [Back]
      lssf lists information about a special file.  For each special_file
      name, lssf determines the major number of the special file and whether
      it is block or character (using stat(2)).  It then scans the system
      for the device that is associated with the special file.  When the
      device is found, the minor number of the special file is decoded.  A
      mnemonic description of the minor number is printed on standard output
      along with the hardware path (i.e., address) of the device.  Mnemonics
      used to describe the fields are closely related to the options used
      with mksf (see mksf(1M)).

 DIAGNOSTICS    [Toc]    [Back]
      Most diagnostic messages from lssf are self explanatory.  Listed below
      are some messages deserving further clarification.  Warnings allow
      lssf to continue.

    Warnings    [Toc]    [Back]
      No such device in the system
                There is no information about the device in the kernel.  The
                special file is not usable.  Use rmsf to remove the special
                file (see rmsf(1M)).

      Character major <major> is not in the kernel
      Block major <major> is not in the kernel
                The major number associated with the special file is not in
                the kernel.  Use kcmodule to add the appropriate driver to
                the kernel (see kcmodule(1M)).

      Device driver <name> is not in the kernel
      Device class <name> is not in the kernel
                The indicated device driver or device class is not present
                in the kernel.  An open() of a special file pointing to an
                unusable device fails.  To make the device usable, the
                appropriate device driver and/or device class must be added
                to the kernel using kcmodule(1M)).  If the device is no
                longer needed, rmsf should be used to remove the special
                files and update /etc/ioconfig.

      <special_file> is not a special file
                The file is not associated with an I/O device.

 EXAMPLES    [Toc]    [Back]
      Suppose a special file is created with the command mksf -d tape2 -H
      8.6.1 -b 1600 -a rmt/c2t6d0m.  The command lssf rmt/c2t6d0m then

           tape2 instance 2 bpi 1600 att address 8.6.1 rmt/c2t6d0m
