    General Information

    ****** PLEASE READ THIS ENTIRE NOTICE *********

    This package is being provided to allow the update of older IBM 7332-110 4mm tape drives to the current level of microcode that is currently shipping from IBM.

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


    Microcode Install Information:

    In order to complete the microcode download to a IBM 7332-110 you will need either the Atape Device Driver installed on the system or you will need the Genucode program along with the microcode and dsdata file in this package.

    This package, the 7332110 package, will get you to step where you will need to use the tapeutil program( part of Atape, if Atape is installed on the system) or GENUCODE to download the microcode into the tape drive.

    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.

    Atape

    The Atape program was shipped with the IBM 7332-110, but it is likely that it has been updated since the 7331-110 was shipped.
    The current Atape is available from the WEB at:
    ftp://ftp.software.ibm.com/storage/devdrvr/AIX

    Genucode

    You will need to get the Genucode package from eServer pSeries WEB site:
    http://techsupport.services.ibm.com/server/mdownload/download.html
    For genucode you will need the microcode and dsdata file in this package.

    This README will get you to step where you will need to use Genucode or Atape to download the microcode into the tape drive.


    Operating System levels supported:

    All levels of AIX that this product was announced on.


    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. If you used Genucode to install the microcode the new level of microcode will not show in the Vital Product Data. To have the Vital Product Data show the new level you must use the AIX rmdev and mkdev commands described in Genucode part of the install process.


    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 eServer 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.


    Microcode History

    The microcode update will bring the IBM 7332-110 4mm tape drive up to the current level of microcode which is:
    758B

    59H4166 59H4168 7580 Improve read capability of media created on older non IBM tape drives.

    59H4166 59H4168 758B Improper handling of the end of tape indication on DDS||||(DDS1) tapes If an application wrote a DDS1 tape to the end of the tape, AIX would report a TAPE_ERR5. All the data up to the TAPE_ERR5 was reported was saved to the tape, but AIX would not request a second tape to be mounted to continue writing additional data. This would only occur on DDS1 tapes.


    Display 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 7332-110 4mm tape drive do the following AIX command:

     lscfg -vl rmt0               <--- change the drive number to reflect
                                       the actual rmt address of the
                                       IBM 7332-110 4mm tape drive.
    

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

      rmt0              00-00-01-4,0      7332 4mm Auto Loader SCSI Tape

    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 microcode downloaded correctly to the system do the following AIX command:  
    sum IBM-S*
    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.
    14297 513 IBM-STL496000N.758B.00000101


    Determine which utility to use for download

    You now will need to determine if the Atape device driver is installed. 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.

    Note: If the Atape driver is down level the you may want to consider updating to the current Atape level.
    If the Atape device driver is installed skip to the step:
    "Install with Atape".

    If Atape is not installed you now need to use Genucode to complete the microcode install process.


    Install with Genucode

    If the Atape device driver is not installed you will use genucode to do the microcode install:

    You now need to use the instructions in the GENUCODE package to complete the microcode install process.


    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/7332110/IBM-STL496000N.758B.00000101

    Follow the remaining instructions to complete the install.
