• Closed as program error.

Error description

• The label libvolume command may return ADSM_DD_LOG2 errors in
  the AIX errpt when using an IBM 3996 or Plasmon G series optical
  library with UDO drives. The volumes are labeled and can be used
  without error.

  Device driver tracing showed the TUR failure:

  **ADSM_OPIOC_TEST_UNIT_READY**  END  rc 46, status 46, compcode
  306
  .
  The completion code of 306 is DD_DRIVE_OR_MEDIA_FAILURE.  Since
  this completion code means there could be something wrong with
  hardware or media the TSM device driver will log this failure to
  the OS error log.
  .
  *NOTE*
  1) The corrections are specific to UDO1/UDO2 drives.
  2)  The drive  behavior can be different on different platforms
  depending on the HBA and native driver.  This means on AIX TUR
  will fail but on Windows or other Unix TUR might not fail, hence
  the error might not be logged in the system error logs.
  .
  Platforms affected:
  TSM 5.4 and 5.5 on AIX
  .
  Initial Impact: Low
