options

Purpose

     Defines the valid choices for each ddi option.

Description

     The /etc/ddi/options  file contains a sorted  list of the
     valid choices  for each keyword  used in ddi  files.  The
     devices  command  uses this  file  to  display the  valid
     choices  for the  keywords  during the  add, change,  and
     showdev subcommands.

     Each line must follow the following format:

        optionchoices

     where:

     option    This field  is exactly  20 characters  long, is
               padded on  the right with spaces,  and contains
               no  tab characters.   An option  is one  of the
               following:

               keyword          The  keyword   for  which  the
                                valid choices are to be speci-
                                fied

               keywordadapter   The  keyword  followed by  the
                                adapter name

               keywordclass     The  keyword  followed by  the
                                device class

               keywordtype      The  keyword  followed by  the
                                device type

               keywordstanza    The  keyword  followed by  the
                                name of  the device  stanza in
                                the system file.

               The devices command looks for one of these com-
               binations  based on  the  setting  of the  opts
               keyword in  the kaf  file for the  device.  See
               "kaf" for details about the opts keyword.

     choices   This field  is exactly  29 characters  long, is
               padded on  the right with spaces,  and contains
               no tab characters.

     Note:  The /etc/ddi/options file must be sorted alphabet-
     ically by  the option field.   If it is not  sorted, then
     the devices command  displays incorrect information about
     the options available for a given keyword.

     The use  of extended  characters in  the /etc/ddi/options
     file is not supported.
