    Drive Microcode Version: 07wR

    Robotics Microcode Version: 2.2


    General information

    ******* Please read this entire notice *********

    This package is being provided to allow the update of older IBM 7334-410 8mm Tape Library to the latest level of microcode that is currently shipping from IBM.

    The Robotics microcode is the same level shipped with all 7334-410 Libraries. Since the latest Robotics microcode is the same as shipped with the library, the Robotics microcode is not included with this package.
    Information to determine the Robotics microcode level and update the Robotics microcode level are included in this package as a reference only.

    Customers are encouraged to install the latest microcode level themselves. The microcode and instructions are available the IBM external web site:
    http://techsupport.services.ibm.com/server/mdownload/download.html


    Operating System levels supported:

    All levels of AIX that this product was announced on.


    Installation Time:

    The typical time to install this microcode is .5 hrs.
    The microcode becomes active when installed and does not require a system reboot to become active.


    Can microcode be installed Concurrently?

    Yes, but the tape drive must be available with no tape in the drive, and no other processing running to the tape drive.


    Is system reboot needed to activate the microcode

    A reboot is not needed as the microcode is active in the drive when the drive completes microcode download. But to have the Vital Product Data show the new level you must use the AIX rmdev and mkdev commands.


    Drive Microcode Download information:

    In order to complete the microcode download to the tape drive you will need to use the AIX 5.1 diagnostics and higher, or the Genucode program. If the system does not have the AIX 5.1, or later, diagnostics you will need to get the Genucode package from the WEB at:
    http://techsupport.services.ibm.com/server/mdownload/download.html

    For either the AIX diagnostics or for Genucode you will need the microcode and dsdata files in this package.
    This tape drive package will get you to step where you will need to use the AIX 5.1 and higher Diagnostics or Genucode to download the microcode into the tape drive.


    Library Microcode Download information:

    In order to complete the microcode download to a IBM 7334-410 Library Controller you will need the Atape Device Driver installed on the system. Use the Tapeutil part of Atape to download microcode to the 7334-410 Robotics.


    Atape

    The Atape program was shipped with the IBM 7334-410. It is also available from:
    ftp://ftp.software.ibm.com/storage/devdrvr/AIX


    Additional Cautions

    Do not power off the tape drive during microcode download as this may damage the tape drive microcode requiring the tape drive to be replaced.

    Remove any tape cartridge from the drive prior to attempting the microcode download.


    Machines Affected:

    All pSeries and RS/6000 machines this product was announce on. In general if the tape drive configures and is available with the VPD showing the Machine Type and microcode level as described in this README the machine is one affected.

    Display Tape Drive Microcode Level

    Note: In some cases you may already have the most current level of microcode already installed. The following instructions show you how to check the tape drive microcode level.

    To display the level of microcode in the IBM 7334-410 8mm tape drive do the following AIX command:

     lscfg -vl rmt0               <--- change the drive number to reflect
                                       the actual rmt address of the
                                       IBM 7334-410 8mm tape drive.
    

    The output of the lscfg command will look like one of the following with the "Device Specific.(Z1)" showing the microcode level:

    Change in Machine Type Model Information

    Starting with microcode level 03cR the Machine Type and Model change

    From:
    Machine Type and Model......IBM-60GB
    To:
    Machine Type and Model......Mammoth2


    Multiple Microcode Downloads Required

    If the Machine Type and Model do not show Mammoth2 it will be necessary to do two(2) microcode downloads to the tape drive. This is necessary because AIX Diagnostics and Genucode check the Machine Type and Model as part of the verification for microcode download to the tape drive.

    If the Machine Type and Model has IBM-60GB then it is necessary to install both:

    If the Machine Type and Model has Mammoth2 then it is only necessary to install only:


    Display Robotics Microcode Level

    To display the level of microcode in the IBM 7334-410 Robotics do the following AIX command:

     lscfg -vl smc0               <--- change the drive number to reflect
                                       the actual smc address of the
                                       IBM 7334-410 Robotics controller
    

    The output of the lscfg command will look like the following with the "Device Specific.(FW)" showing the microcode level:

      DEVICE            LOCATION          DESCRIPTION

            Device Specific.(FW)........2.2
    


    Putting the microcode on the system

    There are 2 ways a user can get the microcode files. Each of these will put the microcode on the user's system but the user may have to move the files to appropriate directory for system use.

    From the IBM WEB site via the user downloading the files.

    When the user downloads the microcode files from the IBM web site the packaged microcode files will be put into the /tmp directory.

    From a CD-ROM.

    Note: AIX commands and file names are case sensitive.
    If the users AIX permission does not allow the copy to the above stated directory or file then the user will be prompted for a new location.


    Packaged Microcode Files

    AIX bin file


    Check Microcode Checksum

    To insure the file downloaded correctly to your AIX system you should use the AIX command sum to verify the checksum of the downloaded file.
    cd /tmp/60GB8mmL_web
    sum IBM-60GB.03cR.A1700296
    The output of the command will be the checksum and it must match the following, if it does not match then redo the download and file extraction.
    18242 1 IBM-60GB.03cR.A1700296
    OR
    sum Mammoth2.07wR.A1700296
    The output will be:
    16750 1192 Mammoth2.07wR.A1700296


    Installing Drive Microcode

    Installing Microcode with AIX Diagnostics

    If the system has AIX 5.1 or higher installed you can update the microcode in the tape drive with the AIX diagnostics. To update the microcode using the AIX diagnostics it is necessary to copy the files from the /tmp/60GB8mmL_web directory to the /etc/microcode directory with new names as AIX diagnostics only looks for microcode in the /etc/microcode directory. Additionally AIX diagnostics require the microcode and dsdata file to have a different naming convention then genucode uses.

    For instructions on using the AIX Diagnostics microcode download capability refer to the section of this document titled "How to Use AIX 5.1 Diagnostics Microcode Download".

    Installing Both Microcode Files with AIX Diagnostics

    Use the following AIX commands to copy the files to the /etc/microcode directory:
    cd /tmp/60GB8mmL_web
    cp dsdata /etc/microcode/IBM-60GB.A1700296.dsdata
    cp IBM-60GB.03cR.A1700296 /etc/microcode/IBM-60GB.A1700296.03cR
    cp Mammoth2.dsdata /etc/microcode/Mammoth2.A1700296.dsdata
    cp Mammoth2.07wR.A1700296 /etc/microcode/Mammoth2.A1700296.07wR
    Run AIX 5.1 Diagnostics(or higher) selecting the 03cR microcode to download.
    Run AIX 5.1 Diagnostics(or higher) selecting the 07wR microcode to download.

    Installing the Mammoth2 Microcode File only with AIX Diagnostics

    Use the following AIX commands to copy the files to the /etc/microcode directory:
    cd /tmp/60GB8mmL_web
    cp Mammoth2.dsdata /etc/microcode/Mammoth2.A1700296.dsdata
    cp Mammoth2.07wR.A1700296 /etc/microcode/Mammoth2.A1700296.07wR
    Run AIX 5.1 Diagnostics(or higher) selecting the 07wR microcode to download.

    Installing Both Microcode Files with Genucode

    Note: The dsdata file for the IBM-60GB and Mammoth2 microcode files are unique to each microcode file, so it is necessary to copy the particular microcode file and its associated dsdata file just prior to running genucode for that microcode file.

    The /. (slash dot) in the following commands uses the input name for the output name of the file.

    Use the following AIX commands to copy the files to the /etc/microcode directory:
    cd /tmp/60GB8mmL_web
    cp dsdata /tmp/.
    cp IBM-60GB.03cR.A1700296 /tmp/.
    Run genucode

    Note: It is not necessary to recycle power to the drive or do the AIX commands rmdev and mkdev after the first microcode download. The microcode is active in the drive when the download completes.
    cp dsdata /tmp/.
    cp Mammoth2.07wR.A1700296 /tmp/.
    Run genucode

    Follow the instructions in the Genucode package to do the microcode download. After completing the Genucode instructions be sure to do the AIX commands:
    rmdev -l rmt0
    mkdev -l rmt0

    This will update the Vital Product Data in AIX so the new microcode level plus any other data that was changed will be shown.

    Installing the Mammoth2 Microcode File only with Genucode

    If the tape drive Machine Type and Model already is Mammoth2 then it is only necessary to install the new Mammoth 2 microcode files.

    The /. (slash dot) in the following commands uses the input name for the output name of the file.

    Use the following AIX commands to copy the files to the /etc/microcode directory:
    cd /tmp/60GB8mmL_web
    cp dsdata /tmp/.
    cp Mammoth2.07wR.A1700296 /tmp/.
    Run genucode

    Follow the instructions in the Genucode package to do the microcode download. After completing the Genucode instructions be sure to do the AIX commands:
    rmdev -l rmt0
    mkdev -l rmt0

    This will update the Vital Product Data in AIX so the new microcode level plus any other data that was changed will be shown.


    Installing Robotics Microcode

    The Atape device driver is required to install microcode into the 7334-410 Robotics.
    To determine if the Atape device driver is installed do the following AIX command:
    lslpp -l Atape.driver

    This will show the level of the Atape driver if it is installed. If the Atape device driver is installed skip to the step "Install with Atape".

    If the Atape device driver is not installed you now need to install Atape. A copy of Atape was shipped with 7334-410 and is also available from the IBM web site listed previously in these instructions.


    Install with Atape

    You now need to issue the Atape tapeutil command:
    tapeutil
    Then select Tape Drive Service Aids
    Then select Microcode load
    Then select the tape drive you are going to download microcode to.
    Then enter the file name of the microcode file you are going to use for the download:
    /tmp/IBM-60GB.Robotics.xxx

    Follow the remaining instructions to complete the install.


    How to Use AIX 5.1 Diagnostics Microcode Download

    There are 2 ways to do the microcode download using the AIX diagnostics.

    Using the AIX Diagnostics menu

    To use the AIX 5.1 diagnostics menu for microcode download do the following:  
    diag (enter)  
    Task Selection (enter)  
    Download Microcode (enter)

    Select the drive you wish to download microcode to and follow the system instructions.

    Note: When the system asks where the microcode file is to be found select /etc/microcode, not diskette.

    Using the AIX Diagnostics via command line input.

    The command line to download microcode will use the highest level of microcode in the /etc/microcode directory for the device selected. To use the AIX 5.1 diagnostics command line input for microcode download do the following:

    Note: If the previous level of microcode is not in the /etc/microcode directory you will need to use the -f option(force) as the diagnostics expect the previous level to be present in the /etc/microcode directory.  
    diag -c -d rmt0 -T "download" (enter)

    or

    diag -c -d rmt0 -T "download -f" (enter)
