• Closed as program error.

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.
