Error description

  • When attempting to access a tape drive, the Tivoli Storage
    Manager server will first attempt to open the tape device and,
    if successful, will then attempt to verify the appropriate
    device has been opened by comparing the serial number returned
    from the device with the corresponding serial number stored in
    the drive descriptor on the Tivoli Storage Manager server.  In
    the event that the tape device cannot be opened, an ANR8779E
    error is generated and the corresponding errno returned from the
    failed open() request is displayed.  If the tape device is
    successfully opened, but there is a discrepancy between the
    serial number returned from the device and the serial number in
    the drive descriptor, an ANR8779E error will be generated, but
    the message will display the file handle of the opened device.
    In situations where the tape device is successfully opened, but
    validation of the drive serial number fails, the ANR8779E error
    is misleading as this error indicates a problem opening the tape
    drive.
    
    An additional message (ANR9010W) was introduced in the 6.2.5 and
    6.3.4 versions of the Tivoli Storage Manager server code that
    will now indicate when a device cannot be successfully accessed
    due to drive validation having failed.  There are, however,
    certain conditions under which drive validation can fail and the
    ANR8779E error will be generated with no corresponding ANR9010W
    message.  This APAR is being opened to address the need for the
    Tivoli Storage Manager server to consistently generate the
    ANR9010W message when drive validation fails.

Local fix

  • Enable SANDISCOVERY on the Tivoli Storage Manager Server to
    allow for the path definitions to be dynamically updated when
    serial number discrepancies are identified.
