The
disk-dmc utility performs firmware
upgrade by issuing SCSI
Write Buffer command
(mode 5 or mode 7) on specified device(s).
disk-dmc uses the
uscsi(7I) interface so the execution is limited
to the root user.
The following options are supported:
-
-
-d
dsk- Specify the drive that will be targeted for firmware upgrade.
dsk is the drive path in the form of
/dev/rdsk/c?t?d?p0 Requires
-p. This option is mutually exclusive
with the -m option.
-
-
-s
-7|5- Change default (5) write buffer command mode. Supported values are 5 and
7. If 5 is selected
disk-dmc will
attempt to download the full firmware file onto the specified drive(s) in
one write buffer command. If 7 is selected
disk-dmc will break up the firmware
file into 32K chunks and send as many write buffer commands as needed to
complete the firmware transfer.
-
-
-h- Display the command line usage message.
-
-
-l- List the drives on a system available for firmware upgrade and display
information specific to each device. This is implied if
disk-dmc is run without any
arguments.
-
-
-m
str- Specify the model of drive(s) to download firmware to. All discovered
drives whose model exactly matches the
str will be upgraded. Requires
-p. This option is mutually exclusive
with the -d option.
-
-
-p
path- Specify the path to the binary firmware image file you want to write to
the device.
-
-
-v- Verbose mode, turns on extra debug messages.
-
-
-w
delay- Number of seconds to delay check for drive readiness after downloading the
firmware. Also used for drive preparation timeouts.
