    SCSD (Self Configuring SCSI Device) Tape Drive Service Aid


    Utape

    Provides the ability to display and monitor tape drive information for tape drives that are supported on AIX by the Self Configuring SCSI device support. Supported functions include the ability to display time since drive was last cleaned, and other drive information.

    On AIX AIX 4.1.5, or later, systems with Self Configuring SCSI Drives(SCSD) utape will work with the following tape drives:

    While signed on as root utape can be run as a standalone program or under AIX Diagnostics on the newest AIX levels.
    Run AIX diagnostics, then select Service Aids, then select SCSD (Self Configuring SCSI Device) Tape Drive Service Aid.
    Or
    Run standalone mode by entering:
    cd /usr/lpp/diagnostics/bin
    For a list of the command structure:
    ./utape ?
    Usage: utape -h ? -c -e -t -l -d
    where:

     Samples of using "utape":
            ./utape -c -d rmt0
              or
            ./utape -ce -d rmt0
            Processing data...
            Usage time since the drive was last cleaned: 0.27 hours.
            Device rmt0 does NOT need cleaning at this time.
    
     Sample of parsing for time since last cleaned:
            ./utape -d rmt0 -ce » grep ":" » cut -d : -f 2
            returns:
            0.27 hours
    

    Utape requires the following PTFs to be installed to eliminate a reset before the data is gotten from the drive:

                       whenever the eject button is pressed and the eventual
                       result is to eject the tape. For example, this
                       message will appear even thought the tape drive is
                       continuing to flush the buffer during a READ or a
                       Write, because the eventual result is to rewind and
                       eject the tape. This will give instant acknowledgement
                       to the operator that the button press was received by
                       the drive. The ICON will change to < < (same as
                       Rewind) when the rewind phase is in process.
    
     EJECT PREVNT    * This message will be displayed if the system has
                       issued a "prevent media removal" command and the drive
                       unload button is pressed. The tape will rewind and
                       unload into the tape cartridge, but the cartridge
                       will not eject from the drive.
    
     READ + **       * The + sign appears whenever the drive is in
                       compression mode. The boxes show the amount of tape
                       used as a percent of the total tape length.  The
                       empty area is shown as equal sign so that the line is
                       complete. There are up to 6 solid squares to follow
                       the message as shown in the following 5 messages.
    
     WRITE + **      * The + sign appears whenever the drive is in
     PROTECTED         compression mode. If a write is attempted on a Write
     ILLEGAL WRT       Protected tape, the PROTECTED message is displayed.
                       The ILLEGAL WRT message is displayed if write is
                       attempted to a for which writing is not supported
                       on this tape drive. This message remains until another
                       tape is inserted that is the correct type or another
                       legal command is issued such as a READ, REWIND,
                       or the eject button is pushed.
    
    Note: ILLEGAL WRT -
                       Only tapes labeled AME(22m or 170m) can be written by
                       this drive. Tapes labeled 15m, 54m, 112m, or 160m are
                       Metal Particle(MP) and cannot be written(eg. read only).
                       After reading an MP tape, the drive MUST BE CLEANED
                       before being able to write to an AME tape, refer to
                       the MUST CLEAN message.
    
     SEARCH **       * Used for high speed searching to indicate the position
                       on the cartridge. The display bar will increase or
                       decrease for forward or backward searches.
    
     REWIND **       * Self explanatory. Display bar reduces in size as
                       rewind occurs.
    
     ERASE  **       * Self explanatory. This occurs very quickly for a short
                       erase.

                            ON        Remains ON after you unload the
                                      cleaning cartridge. If this condition
                                      occurs the likely cause is cleaning
                                      cartridge has expired(been used up) and
                                      the cleaning was not done.

                                      when you reload the data cartridge. When
                                      this condition occurs the likely cause
                                      is a worn out data cartridge. Clean the
                                      drive again and try another data
                                      cartridge. If the problem persists, do
                                      the problem determination procedures.

    Tape Drive Performance/Reliability Checklist

    The Tape Drive Performance/Reliability Checklist is an overview of how to evaluate and prevent tape drive problems.

     Media Selection
                         Use only the tape cartridges supported by your
                         tape drive.  These must be high quality data grade
                         media, such as the IBM data grade cartridge ori-
                         ginally supplied with your drive.
                         Don't attempt to write on previously written soft-
                         ware distribution tapes. Often these tapes will
                         not support being rewritten without modifications
                         to the cartridge. If the cartridges are modified
                         it is possible to cause tape jams or tape misa-
                         lignment.
    
                         The following is specifically addressing 8mm media:
                         - 8mm media of 15m, 54m, 112m, or 160m length is Metal
                           Particle(MP) media.
                         - 8mm media of 22m, or 170m length is Advanced Metal
                           Evaporated(AME) media.
                         - 8mm drives with 2.3GB or 5.0GB capacity Read/Write
                           15m, 54m, or 112m length "MP" media only.
                         - 8mm drives with 7.0GB capacity Read/Write
                           15m, 54m, 112m, or 160m length "MP" media only.
                         - 8mm drives with 20.0GB capacity are Read-ONLY on
                           15m, 54m, 112m, or 160m length "MP" media.
                         - 8mm drives with 20.0GB capacity can Read/Write ONLY on
                           22m, or 170m length "AME" media.
                         - 8mm media of 22m, 160m, and 170m should bear the
                           Recognition System Logo.
    
     The following chart shows the various 8mm tape drives and their supported media with
     cleaning cartridge, recommended minimum cleaning frequency, and corresponding IBM
     Media part numbers(P/N):

      N/A  - IBM does not have a P/N for this media.
      N/S  - The tape drive does Not Support Reading or Writing on this media.
    

     Media Replacement
    
                         Cartridges which are used regularly (e.g.
                         daily/weekly backup tapes) should be discarded
                         after about a hundred uses. Cartridges which are
                         in use when media-related errors are reported by
                         your backup application, or are physically
                         dropped, or are exposed to extremely harsh envi-
                         ronments should be discarded.
     Media Storage
    
                         Protect your cartridges from particulate contam-
                         ination when they're not in use. Put each car-
                         tridge in its protective case or place the
                         cartridge in a dust-tight container designed for
                         tape cartridge storage.  Keep your cartridges in
                         an area where the temperature and humidity are
                         comfortable for you and are relatively constant.
                         Orient cartridges in storage so that their cases
                         are on an edge (vs flat). If cartridges are moved
                         between areas whose temperature or humidity differ
                         greatly, let the cartridge adapt for several hours
                         prior to use.
    
     Cleaning Cartridge Selection/Usage
    
                         Use only the cleaning cartridges supported by your
                         tape drive.  These must be high quality car-
                         tridges, such as the IBM cleaning cartridge ori-
                         ginally supplied with your drive.
                         Refer to the "Media Selection" for proper cleaning
                         cartridge part numbers and their minimum recommended
                         usage.
                         Cleaning Cartridges used in the 2.3GB, 5.0GB, and
                         7.0GB drives are different from those used in the
                         20.0GB drives.
                         Clean your drive once a month or whenever the AMBER
                         LED is turned on solid(not applicable to the2.3GB
                         drives). Clean your drive after any media related
                         error is encountered.
                         Often software distribution tapes are MP media.
                         The 20GB drive MUST BE CLEANED after using MP media
                         (15m, 54m, 112m, or 160m length media) before any
                         subsequent write operation will be allowed.
                         Clean your 2.3GB drive after every 30 hours of
                         reading and writing activity.
                         Observe the remaining cleaning material through
                         the cartridge's window and discard the cartridge
                         when fully used.
    

     Environment
    
                         Locate your tape drive at table top level or higher
                         and away from sources of particulate contamination
                         such as outside doorways, high foot traffic areas,
                         printers, and copiers. Maintain comfortable tem-
                         perature and humidity (ideally 30-40% Relative
                         Humidity) when the tape drive is in use.  Note
                         that this may require a timing adjustment of
                         nighttime setbacks.  Minimize the amount of time
                         cartridges spend in the drive when not in actual
                         use.
    
     Troubleshooting
    
                         If a backup failure occurs, try cleaning the drive
                         and retrying the operation with a new cartridge.
                         Verify that this checklist's recommendations are
                         being followed by the system's operators. Look for
                         trends, process changes, and/or environmental
                         changes. Avoid mechanical loading problems by
                         placing labels only in the designated cartridge
                         spine and top locations and assuring that they are
                         not peeling off or more than two layers thick.
                         Contact your IBM CE if problems persist.

      Note: 8mm 2.3GB, 5GB, 7GB, & 20GB tape drives will log a TAPE_ERR3 when:
            Rewrite % is equal to or greater than 2% with at least 100mb
            of data written,
                or
            Reread  % is equal to or greater than 1% with at least  20mb
            of data read.
      Note: The 20GB drive MUST BE CLEANED after using 15m, 54m, 112m, or
            160m length media before any subsequent write operation will be
            allowed.
    
      Note: TAPE_ERR3 and TAPE_ERR6 are "soft errors" that are posted to
            the AIX error log. In other words, neither error terminated
            the tape operation. They are informational errors that may
            cause AIX to send an informational message to the user.
    
    
    
    
      Note: TAPE_ERR4 errors are often found to be caused by noise on the
            SCSI bus. Noise on the SCSI bus can be caused by one or more
            of the following:
            - Loose SCSI Cables (reseat and tighten all SCSI connections).
            - Bent pins in the SCSI connection (check all SCSI connections
              for bent pins).
            - Device is not supported on the SCSI adapter/system(insure
              device is supported by the SCSI adapter/system).
            - Improper, missing or multiple SCSI bus termination(check SCSI
              bus termination).
            - SCSI cables(insure the proper IBM SCSI cables are used).
            - SCSI cables exceed the supported length for the bus(check the
              IBM information on SCSI bus length).
            - Other SCSI devices on the bus(it may be necessary to remove
              the other SCSI devices one at a time to determine device
              causing the problem).
    

    Tape Drive Problem Determination

    Details the steps that should be taken to resolve user reported problems.

     Tape drives are very expensive and often are not the reason a customer
     cannot read or write a tape. Often the problem is caused by one or
     more of the following:
     - Bad blocksize, the customer attempts to read at one blocksize and
       the tape is written at another. Or the blocksize the customer is
       attempting to write at is preceded by a 0 (ZERO), 0512 is not the
       same as 512.  The zero is recognized by the system as Octal and
       some applications do not support Octal values.
     - Device buffering turned off causing the drive to write every block
       of data as it is received. Normal operation is to buffer the data
       allowing the drive to stream the data to the tape as a continuous
       operation.
     - Writing a tape with one command then attempting to read the tape with
       a non compatible command, such as: writing the tape with a "tar"
       command and attempting to read the tape with a "restore" command.
     - Poor Quality media, or worn out media being used. Clean the drive
       and retest the customer operation with a new IBM data cartridge
       recommended for the drive.
     - Misunderstanding of the meaning of the LED's on the tape drive.
     - Customers not cleaning the tape drive, using cleaning cartridges
       that are used up, or not following the recommended cleaning frequency
       or cleaning instructions.
     - Not cleaning the tape drive after an I/O error prior to retrying
       the failing operation.
     - Improper SCSI bus termination.
     - Conflict of tape drives SCSI address with another device on the bus.
     - Other device causing "noise" on the bus.
     - Environment not suitable for tape drive operation.
     - PTF's level of the system does not support the tape drive.
    

    If a customer is experiencing problems with IBM tape drives, 1/4", 4mm, 8mm, or DLT tape drives you should do the following before replacing any parts:

    Note: There may be times when you want to reset a tape drive to clear an error condition(including stuck tape) without powering off the tape drive. It is possible on most IBM 1/4", 4mm, 8mm, and DLT tape drives to reset the tape drive by pressing and holding the eject button depressed for 30-45 seconds(drive power must be ON).
    Another way to reset the tape drive is to sign on the system with root authorizaion and issue the AIX command: diag -c -d

    1) Clean the tape drive using the IBM Cleaning Cartridge:
       1/4" Tape Drives Cleaning Cartridge P/N 16G8572(Not for 7207-122/315)
            50 Cleanings

            12 Cleanings on 2.3GB Drive    22 Cleanings on 5GB & 7GB Drive
             (On the 5GB 8mm tape drive Microcode 6S0 or higher is required,
             the 2.3GB and 7GB 8mm drives support this cleaning cartridge
             with no microcode dependency.)
            20GB Tape Drives  Cleaning Cartridge P/N 59H2898
            (Only use this cleaning cartridge on the 20GB 8mm Drive)
            18+ Cleanings (18+ because drive varies cleaning tape used
                           based on cleaning from MP tape or AME tape, etc.)
    
       DLT  Cleaning Cartridge P/N 59H3092
            20 Cleanings
    
    2) Determine that there is no conflict of SCSI addresses between the
       tape drive and any other SCSI device.
       lsdev -Cs scsi
    
    3) Check all SCSI connections. Insure all connections are secure, screws
       or clips are tightly attached.
    
    4) Insure the proper terminator is in use. Check the P/N. Insure the
       terminators are securely attached.
    
    5) Run the tape drive diagnostics using the IBM test tape or diagnostic
       tape:

    6) Review the AIX Error Log for all errors around the time the customer
       is unable to process the tape. The AIX command to review the log is:
       errpt -a » pg
    
    7) Do a dd of the tape to determine if there is data on the tape and
       also determine the blocksize the tape was written at.
       - Determine the blocksize currently set for the tape drive on the
         system. Remember this blocksize:
         lsattr -El rmt0
       - Set the tape drives blocksize to 0 (if not already at 0):
         chdev -a block_size=0 -l rmt0
       - Determine the blocksize the tape was written at:
         dd if=/dev/rmt0 bs=128k count=1 » wc -c
       - Use the chdev command to set the blocksize for the tape.
       - Process the tape.
       - Set the tape drives blocksize to the previous setting(you remembered
    
    8) If another system is available attempt to read the customers tape
       on the other system.  If it can read the tape then check the
       blocksize set in the "good" system to insure it matches the
       system where the tape could not be read.
    

    9) Often customer media problems cause drive replacements. Media problems
       can be identified by having the customer clean the tape drive several
       times and write and read from new IBM media. This will often result in
       a customer replacing a single tape that solves the customer problem.
       Check what brand of media the customer is using and insure it is
       supported on the device.
       The following is the proper IBM media for each drive:

    10)The Tape Drives Microcode level is important in that there have
       been many fixes for customer problems incorporated in the new levels
       of microcode for the 4GB4mm and 5GB 8mm tape drives. The level of
       microcode in the customer drive is field upgradeable without changing
       the tape drive.
       The current microcode levels are:

       To determine the microcode level in the tape drive use the following
       AIX command:
       lscfg -vl rmt0   <- the Z1 or FW field will show the microcode level
    

    11) The IBM 7013 model 560 thru 59H model 7013 require the drive
        to be isolated from frame ground. These systems require internal
        tape drives to have isolators on the sides of the tape drives.
        When replacing a tape drive it is important to insure the 7013
        systems that require tape drive isolation have the isolator installed
        on the tape drive. Insure the isolators are installed on the customers
        7013 if required. Isolators are shipped with the FRU. The following
        are the isolators required:
    
                            Isolator P/N's

    12)Only after all this is done should the tape drive be exchanged.
    

    Help Desk Guidelines

    The following is an outline of how a customer help desk should operate with regard to tape drive operations:

    The key to resolving the problems is to determine what is different between success and failure at one site or between sites. To do this the following will help:

    - Establish and publish backup practices. This helps all understand
      the importance of the data being backed up, what is expected to be
      done, and who is responsible for doing each item.
    
    - Establish and publish help desk procedures. This is helpful to both
      the help desk and the customer sites. This helps both understand
      what is expected of each other plus identify what is to be done by
      each.
    
    - Media must be standardized, sites should get media, both data
      cartridges and cleaning cartridges from the same source.  Provide the
      sites a simple way to get the data cartridges and cleaning cartridges
      they need.  This reduces the risk of unsupported media from being used.
    
    - Label each data cartridge with the day of the week(on the data
      cartridge).
      Each site should always have a new sealed spare data cartridge.
    
    - Label each data cartridge and cleaning cartridge with the date the
      customer first put it in service.
    
    - Manuals shipped from IBM with the system or tape drive need to be
      kept with the system for Customer and CE use.
    
    - Each tape drive is shipped from IBM with a Diagnostic/Test cartridge.
      This cartridge needs to be kept with the drive for Customer and CE
      use.
    
    - Monitor cleaning to insure the tape drives are cleaned on a regular
      basis.
      Tpusage  - can be used for the  4GB 4mm tape drive.
      Cleanchk - can be used for the  5GB and 7GB 8mm tape drive.
      Utape    - can be used for the 13GB 1/4", 12GB 4mm, 20GB 8mm, and 35GB
                 DLT tape drives.
    
      Utape is part of the AIX diagnostic package.
      Tpusage and Cleanchk are available from your IBM CE or IBM marketing as
      "use as is programs".
    
    - Determine cleaning cartridge status and discard used up cartridges.
      Each site should always have a new sealed spare cleaning cartridge.
    

    - Monitor backups to determine the following:
      - Insure backup completed successfully
      - Determine the type of backup failure and track the following for
        that site:
        - Was the backup attempted?
          - Did the backup put an error in the AIX error log.
            - TAPE_ERR1 is likely a media failure.
              Did terminate the backup.
            - TAPE_ERR2 is normally a drive failure, but can be caused by
              a media failure.
              Did terminate the backup.
            - TAPE_ERR3 is likely media starting to fail.
              Did NOT terminate the backup.
            - TAPE_ERR4 Unknown cause requires further analysis.
              Did terminate the backup.
            - TAPE_ERR5 Unknown cause requires further analysis.
              Did terminate the backup.
            - TAPE_ERR6 5/7GB, and 20GB 8mm tape drives log this error when
              the drive exceeds the preset limit of tape motion hours since
              the drive was last cleaned.
              Did NOT terminate the backup.
        Note: The 20GB 8mm will also set the cleaning indicator and log the
              TAPE_ERR6 on most media errors.
            - Log the day of the week, and track this to determine if one
              tape is failing or are all failing. This will identify media or
              drive problems.
    
    - Over cleaning a tape drive will not normally damage most tape drives
      when the approved cleaning cartridge is used.  On every backup failure
      where backup was attempted and failed, the tape drive should be cleaned
      with the approved cleaning cartridge.
      Note: On some drives over cleaning may damage the drive, review the
            drive information on cleaning, on those drives follow the drive
            recommendation.
    
    - Prior to placing a service call attempt a simple backup to another
      tape cartridge to help determine the cause of the failure. Often
      replacing a single data cartridge will resolve the problem.
    
    - When a service call is required, allow time and access for the CE to
      do problem determination and problem correction. This includes allowing
      the CE time and access to run diagnostics prior to and after parts
      replacement.  It is desirable to allow the CE authorization to run
      concurrent diagnostics, a special id may be required for this as it
      requires root authorization.  This will allow the CE to do problem
      determination without having to take the system down for dedicated CE
      diagnostics.
    
    - Sites that are dusty should keep the system at least 24" off the floor
      to reduce the exposure to dirt and contamination.
    
    - Sites that show persistent media and drive failures that are following
      established cleaning and media procedures should be considered for
      filter enclosures.

    This drive is sensitive to the delivery of data to the tape drive. Some applications take the blocksize and block the data block into larger blocks for transfer to the tape drive. Some applications call this the blocksize, or the buffer size or blocking factor. Whatever it is called you need to understand that this tape drives performance(data rate)is greatly effected when the system sends small blocks of data. At this time the AIX maximum size is 256K. You will need to test your application to see at what blocking you get the best performance for your tape drive. The minimum recommended blocking for this drive is 32k. Some AIX commands already use 32k or larger blocks when writing, some do not.

    The following are a few of the AIX commands and blocking information:
    
     backup   <- will either use 32k or 51.2k as default depending if backup
                 by name or not.    No customer change required.
     tar      <- default is 10k (error in tar manual stating 512kb)
     tar  needs the customer to use at minimum    -N64
     mksysb   <- uses backup on AIX 4.1    No customer change required.
     dd   needs the customer to use at minimum  bs=32k
     cpio needs the customer to use at minimum    -C64
    

    Users should insure the blocksize they select is supported by the users application.

    Users should insure the blocksize they select is supported by the users application.

    As an example: Using a blocksize of 1024 and backing up 32GB of data will take approximately 22 hours. Same 32GB of data backed up at a block size of 32k will take approximately 2 hours. Small blocksizes have a significant impact on performance but only a minimal impact on capacity. However 2.6 format(density) and 6 format(density) are significantly impacted in capacity by using small blocksizes, they don't pack the data in the drives internal 8k block.

    Programs For Monitoring Tape Drive Cleaning


    Utape for SCSD tape drives

    On AIX 4.1.5, or later, systems with Self Configuring SCSI Drives(SCSD) utape will work with the following tape drives and their internal equivalent:

    The AIX Diagnostic program, "utape", allows a user to remotely monitor the time since a tape drive was last cleaned and the cleaning status LED. Users can use this program to determine if a tape drive needs cleaning or determine how many tape motion hours have elapsed since the drive was last cleaned.

     To run the program "utape":
            sign on with root authorization
            cd /usr/lpp/diagnostics/bin
    
     To display "utape's" option list:
            ./utape -?

    SCSI Address Setting

    SCSI address settings is important as the SCSI address:

    Most SCSI devices will need to be powered OFF then ON again for the device to recognize the new address if the device address was changed with the device powered ON.

    In general the SCSI adapter will be set at SCSI address of 7, but this is not always the case, so it is best to determine the SCSI address of the SCSI adapter.
    To determine the SCSI adapters in the system do the following AIX command: lsdev -C » grep scsi
    The output will be: scsi0 Available 00-04 SCSI I/O Controller

    To be sure of the SCSI adapter address do the following AIX command for the adapter you are going to attach to: lsattr -El scsi0 » grep id
    The output will be: id 7 Adapter card SCSI ID

    Note: High Availability(HA) systems often use 5 and 6 as the SCSI adapter address. Some systems restrict the SCSI address, refer to your system manuals to determine any system restrictions.
    To be sure of the addresses of other devices are already using on the SCSI bus do the AIX command: lsdev -Cs scsi

    Valid SCSI addresses for Narrow devices(8 bit) are 0 thru 7, with 7 usually reserved for the SCSI adapter.

    Valid SCSI addresses for Wide devices(16 bit) are 0 thru 15 with 7 usually reserved for the SCSI adapter. When a Wide device is attached to a narrow bus the available addresses are the same as if the device was a narrow device.

    Note: On systems that use the Common Hardware Reference Platform(CHRP), the SCSI address 15 may be used for CHRP address. The backplanes use this address on CHRP boxes to ID backplane FRU locations codes in CHRP Error logs. The ID 15 is hard wired into the I-35 backplane. Any devices tagged with a SCSI address of 15 and attached to the SCSI interface used by the backplanes are going to have a conflict of address, so if in doubt don't use the SCSI address of 15. Some systems use more than 1 CHRP and use more than 1 SCSI address on the same SCSI adapter.. Currently the F50, H50, S70, and SP2 equivalents use CHRP.
    The lsdev -Cs scsi command will show the following(adapter ID will vary):
    ses0 10-68-00-15,0 SCSI-Enclosure Services Device
    There may be multiple SCSI adapters in the system an each may have a SCSI-Enclosure Services Device at address 15.


    Tape Drive Performance

    The following information applies to most AIX tools(tar, cpio, backup, restore, dd, etc..) used to write or read data from tape, backup and restore are used as generic names only.

    Customers backing up the same size data or restoring data can find that the amount of time it takes to backup/restore data may vary from backup to backup or restore to restore. Most tape drives work best when the tape drive can keep the tape moving at a constant speed(streaming). The more the tape drive is able to keep the tape streaming the shorter the backup/restore time will be. The ability of the tape drive to keep the tape streaming is effected by many factors.

    These factors include:


    Device Driver/Robotics Driver

    Atape is the device and robotics driver for the 7332-005 and 7332-110. Atape is the robotics driver for the 7331-205, 7331-305, and 7336-205.

    Note: A minimum Atape level required for microcode download on the 7332-005 or 7332-110 is Atape 2.5.2.10.

    To check the level of the Atape driver on a system do the following AIX command:
    lslpp -l Atape.driver

    The current level of Atape device driver is available from Internet at:

    or

     The requested drivers can be obtained via anonymous ftp service.
     Access the ftp server as you would an anonymous service.
     The drivers are in directory /devdrvr.

         /devdrvr/AIX/Atape.x.x.x.x.bin       <- Where x is the Atape level
    

    You should remove the older Atape driver before installing a newer level. To remove an older level of the Atape driver do the Atape command:
    /usr/lpp/Atape/lpp.deinst

    You should remove the RMT's that of the devices supported by Atape before installing a newer level of the Atape driver. To do this use the AIX command:
    rmdev -dl rmtx <-- where x is the device you wish to remove

    Do this for each of the RMT's associated with the device.

    The AIX command to install the Atape driver is:
    Diskette:
    installp -acXd /dev/rfd0 Atape.driver

    Directory: installp -acXd /pathname/filename Atape.driver

    Note: If after rebooting your system you see a defined device at the same address as the 7332-005 you may need to do an AIX command of
    rmdev -dl rmtx <--- where the x is the defined device to remove
    I may then be necessary to then do the AIX bosboot command, refer to your AIX documentation for information on the bosboot command.


    SCSD Tape/Optical Ucode Download Application


    Generic SCSI microcode download utility for SCSD devices

    Note: Do not power the tape drive off immediately after the microcode says it is complete as the tape drive is still doing internal processing that will take a few minutes to complete.

    On the 7205-311, wait until all LEDs stop flashing and the Green Open Door LED is the only LED on.

    Microcode installation instructions:


    Or
    Command line:

    Note: Some systems PATH do not path through the current directory. If your system does not path through the current directory you will need to do the following AIX command to run from the command line:

      export PATH=$PATH:.
    

    You can execute the download utility "GENUCODE" from the command line if the files DSDATA and the binary file are tar'd to a diskette.
      tar -cvf /dev/fd0 dsdata IBM-7205.V52.A0B00E24
    
    Then enter:
    genucode {the user will be prompted for the input device}
    Or
    Standalone -
    Another option would be to copy GENUCODE, DSDATA and the binary file to '/tmp' and execute GENUCODE in standalone mode.

    Note: Some systems PATH do not path through the current directory. If your system does not path through the current directory you will need to do the following AIX command to run from the command line:
    export PATH=$PATH:.

      cd /tmp
      genucode -s rmt0    {rmt0 is Tape drive name}
    

    Note: Standalone mode won't prompt you before executing the download.

    It is not necessary to recycle the System to have the tape drive microcode active.

    Note: If you are going to recycle the tape drive MAKE SURE the microcode download IS COMPLETE.

    Note: If you try multiple microcode downloads to the drive without powering the drive OFF then ON, the microcode download may fail.
