   3 NAME
   4      disk-dmc - firmware update utility
   5 
   6 SYNOPSIS
   7      disk-dmc -h
   8      disk-dmc [-l] [-v]
   9      disk-dmc [-v] -d dsk -p path [-s 5|7] [-w delay]
  10      disk-dmc [-v] -m str -p path [-s 5|7] [-w delay]

  12 DESCRIPTION
  13      The disk-dmc utility performs firmware upgrade by issuing SCSI Write
  14      Buffer command (mode 5 or mode 7) on specified device(s).  disk-dmc uses
  15      the uscsi(7I) interface so the execution is limited to the root user.
  16 
  17 OPTIONS
  18      The following options are supported:
  19 
  20      -d dsk    Specify the drive that will be targeted for firmware upgrade.
  21                dsk is the drive path in the form of /dev/rdsk/c?t?d?p0
  22                Requires -p.  This option is mutually exclusive with the -m
  23                option.
  24 
  25      -s -7|5   Change default (5) write buffer command mode.  Supported values
  26                are 5 and 7.  If 5 is selected disk-dmc will attempt to
  27                download the full firmware file onto the specified drive(s) in
  28                one write buffer command.  If 7 is selected disk-dmc will break
  29                up the firmware file into 32K chunks and send as many write
  30                buffer commands as needed to complete the firmware transfer.
  31 
  32      -h        Display the command line usage message.
  33 
  34      -l        List the drives on a system available for firmware upgrade and
  35                display information specific to each device.  This is implied
  36                if disk-dmc is run without any arguments.
  37 
  38      -m str    Specify the model of drive(s) to download firmware to.  All
  39                discovered drives whose model exactly matches the str will be
  40                upgraded.  Requires -p.  This option is mutually exclusive with
  41                the -d option.
  42 
  43      -p path   Specify the path to the binary firmware image file you want to
  44                write to the device.
  45 
  46      -v        Verbose mode, turns on extra debug messages.
  47 
  48      -w delay  Number of seconds to delay check for drive readiness after
  49                downloading the firmware.  Also used for drive preparation
  50                timeouts.
