SCSI MO Drive Firmware Update Tool (xstm Online Help)
The Firmware Update Tool allows you to update the firmware on a
SCSI MO drive.
MO (Magneto Optical) drives contain "firmware" which is special
software for devices that controls the operation of the hardware
contained in the drive. The firmware controls such critical things as
the communication to the host, the process of reading and writing
data, and many other things.
Over the lifetime of a drive, this firmware gets updated to fix
problems that have been found after the drives were shipped and/or
add new features that have been developed. If an newer version of a
firmware becomes available, it is distributed as a file that contains
all the program code and data. This file needs to be installed into
the drive with special commands that are sent over the SCSI bus. This
tool manages this process and makes the installation of a new
firmware revision in a MO Drive easy.
Not only does this tool install new firmware into the drive, but
it also verifies that the firmware file matches the drive you are
downloading to, that the firmware revisions are correct, and many
other conditions. This prevents the user from making mistakes that
can make a drive unusable by updating it with the wrong firmware
code.
Before you start using this tool, please make sure that you have
already obtained the firmware file that you will need to install the
firmware into the drive.
Read the Step-By-Step Instructions for Unlicensed
Tool section for a detailed description of the process of
installing the new firmware before you continue.
If you experience problems during the process of updating your
drive firmware, consult the What do you if it
doesn't work help topic for recommended actions.
This section provides a detailed description of all the steps
required to update the firmware on an MO drive.
- Load the correct firmware files on your unit under test (UUT)
system. Refer to Obtaining the MO Drive
Firmware File for more information on loading and installing
firmware files.
- Make sure that tool is searching the correct directory path for
firmware files. Refer to Changing Firmware
File Directory Path for more information on changing the
directory path.
- Click "Utility" then then click "Start Menu..." on the pop-up
menu.
- The program will search your current directory path for
firmware files. If it cannot find any files or if the files are not
compatible with the MO Drive (Product IDs don't match or the
revision is older), it will pop up an error message box and return
you back to the main menu.
- If the program found a file for the MO Drive, it will pop up a
dialog box titled "Firmware Update Tool" asking you if you want to
update firmware on this drive. By default, the box is clicked on.
If you don't want to update firmware on the drive, click the box to
disable it (it can be enabled by clicking it again). Click "Start
Update" to continue or "Cancel" to return to the main menu.
- Just before updating the firmware, the program will pop up a
message box warning the user not to interrupt or power cycle the MO
Drive while the program is updating firmware. Click "Continue" to
proceed with the firmware update or "Cancel" to return to the main
menu.
- If the user clicked "Continue", the tool will now update
firmware on the MO Drive. Once the firmware is transferred to the
drive, the drive will reset and restart with the new firmware. Once
the process is complete, the tool will display the results on the
screen and return to the main menu.
This section provides a detailed description of all the steps
required to update the firmware on an MO Drive using the Licensed (or
"Advanced") menu.
- Load the correct firmware files on your unit under test (UUT)
system. Refer to Obtaining the MO Drive
Firmware File for more information on loading and installing
firmware files.
- Make sure that tool is searching the correct directory path for
firmware files. Refer to Changing Firmware
File Directory Path for more information on changing the
directory path.
- Click "Utility" then then click "Advanced Menu..." on the
pop-up menu. If the "Advanced Menu..." button is disabled (grayed
out), you will have to exit out of the firmware update tool and
install the license from the main STM window.
- The program will pop up a dialog box with 2 options that are
disabled by default. The first option allows the program to search
for firmware files whose Product IDs don't match that of the MO
Drive. The second option allows the program to search for older
firmware revisions. CAUTION: You should not change
these options unless you have been asked by a HP Support
Representative to do so, or unless you clearly understand the need
and the impact of changing these options.
- The program will search your current directory path for
firmware files. If it cannot find any files or if the files are not
compatible with the MO Drive (depending on which boxes were checked
in the previous menu), it will pop up an error message box and
return you back to the main menu.
- If the program found one or more files for the MO Drive, it
will pop up a dialog box titled "Advanced Firmware Update Tool
Menu." From this dialog, the user can select which firmware file to
use from a list of files, check whether or not to overwrite the
Product ID of the Drive, check whether or not to update the
configuration of the drive from the firmware files, and finally
select the device to update firmware on. Click "Start Update" to
continue or "Cancel" to return to the main menu.
- Depending on what selections were made in the advanced menu,
any one of up to 3 warning message boxes will pop up. There is a
warning message box for selecting a firmware file with a different
Product ID, one for selecting an older firmware revision, and one
if any of the options in step 2 of the menu were selected.
- Just before updating the firmware, the program will pop up a
message box warning the user not to interrupt or power cycle the MO
Drive while the program is updating firmware. Click "Continue" to
proceed with the firmware update or "Cancel" to return to the main
menu.
- If the user clicked "Continue", the tool will now update
firmware on the MO Drive. Once the firmware is transferred to the
drive, the drive will reset and restart with the new firmware. Once
the process is complete, the tool will display the results on the
screen and return to the main menu.
Before you can start the process of updating the firmware on your
drive, you first need to make sure that the file that contains the
new firmware is present on your system.
CAUTION: If you are using the user interface on a
system other than the unit under test (UUT), or if you use remote
access the firmware files must be present on the UUT system, not the
system that the user interface is running on.
Firmware files for this tool are generally located in the
directory /var/tmp, but they can be stored under any directory.
Firmware files for STM firmware update modules end in the extension
".frm".
If you do not have the firmware file for the MO Drive, you can
download it from the extern website at:
http://www.hp.com/support/optical
This website provides firmware for multiple products and in
multiple file formats for each product. Make sure you are following
the instructions on the website on how to obtain the file for MO
drives and in the STM format.
Firmware files for this tool are generally located in the
directory /var/tmp, but they can be stored under any directory. The
directory path used by both the licensed and unlicensed tools is
displayed on the first line of the dialog menus. These menus simply
display the path; they cannot change the directory path. To change
the directory path, follow these directions:
- Click "File" then then click "Change FW Directory..." on the
pop-up menu.
- A dialog box will pop up that allows the user to enter another
directory path. Type in the new directory path and click "OK" when
finished. Clicking "Default" writes /var/tmp/ in the dialog box;
clicking "Cancel" returns the user to the main menu with the
directory path unchanged.
If the tool is experiencing problems it should explain the
problems in messages that are displayed in dialog boxes and in the
window of the tool. Extensive messages are also logged into the
Test Activity Log. Please make sure that you read
these messages carefully - they are normally the best source of
information about the problem and what to do about it.
Following are some general checkpoints when the download doesn't
work:
- Make sure the drive is powered on.
- Make sure that all the SCSI cabling is correct (termination, no
ID conflicts, correct bus adapter)
- Some autochangers have a switch that allows the selection of
either the single-ended and the differential connector. Make sure
the selector switch is in the correct position.
- Re-generate the map in the STM main window to reflect any
changes in the I/O configuration: Select 'System/Remap System' from
the menu in the STM main window.
- If you are using the STM user interface on a machine different
than the UUT, make sure the STM user interface is connected to the
correct UUT.
- Make sure you have the latest version of the MO tools
installed.
- Make sure you have the right firmware files downloaded. When
you download via ftp, make sure you have used the binary data
transfer mode.
- Make sure you have chosen the right option settings for your
system.
