       NAME
             diskcfg - update system files for PDI drivers

       SYNOPSIS
             /etc/scsi/diskcfg [-S] [-R ROOT] [filename]

       DESCRIPTION
             diskcfg generates System files for the Portable Device
             Interface (PDI) drivers from information provided.  It reads
             input from the provided file, or from stdin if a file is not
             provided, and generates a new PDI configuration based on the
             information.  The input provided describes the PDI drivers to
             be turned on and off, and must exactly match the required
             format or diskcfg will fail.  diskcfg is intended for use with
             the pdiconfig(1M) command or any command producing similar
             output.

          Options
             diskcfg takes the following options:

             -S    Turns on the Debug messages.

             -R ROOT   Uses this value instead of / for the root of a
                       kernel source tree.

             filename  Read input from filename instead of from standard
                       input.

          Input
             The format of the input for diskcfg is:

                   driver name
                   long driver name
                   driver type
                   configure flag
                   unit number
                   dma channel 1
                   dma channel 2
                   ipl level
                   interrupt vector
                   interrupt sharing flag
                   starting I/O address
                   ending I/O address
                   starting memory address
                   ending memory address
                   cpu binding

            Each field must have a value present, and the input must be
            tab separated.  Each input line represents one PDI device.

            Note that diskcfg does not use the shell variable ROOT from
            the user environment as its starting path.  You can specify a
            value for ROOT by using the -R option.  The -R option should
            not be used except for the special case of kernel development
            in a non-root source tree.

         Return Values
            On success, diskcfg exits with a return value of 0.  On
            failure, it returns a non-zero code.

      USAGE
            diskcfg is an administrative command and must be run in single
            user mode.  See init(1M) for information on switching the
            machine to single user mode.

            Any loadable target drivers, such as st01(7), sc01(7), or
            sw01(7), that deal with PDI devices, must be demand loaded
            before executing diskcfg.  See modadmin(1M) for information on
            loading loadable drivers.
