T019: Drive Calibration Failure, Motion OK
Description GUI Description: The library is unable to calibrate the position of a drive.

calibration search pattern completes successfully.
Detection Scenarios Calibration motion completes but edge finding of one or more edges does
not occur.
Root Causes
1. Damaged drive sled calibration fiducial.
2. Dust on picker assembly calibration sensor.
3. Calibration sensor not functioning properly.
4. Drive or Picker position is so far off nominal that search pattern cannot
locate target.

Resolution
1. Perform “DR082: Resolve Library Calibration Failure” on page 6-84.
2. Use the 'Details' option in the RAS ticket to identify which tape drive is
having trouble being calibrated. Reseat the drive sled in another sled bay.
3. Reseat the picker and Y-climber to ensure they are level.
4. Clear the RAS ticket and retry the original operation.
T020: Storage Calibration Failure, Motion OK
Description GUI Description: The library is unable to calibrate the position of a tape
cartridge magazine.
Explanation: System cannot successfully calibrate the position of a storage
magazine but the calibration search pattern completes successfully.
Detection Scenarios Calibration motion completes but edge finding of one or more edges does
not occur.
Root Causes
1. Dust on picker assembly calibration sensor.
2. Calibration sensor not functioning properly.
3. Calibration target not functioning properly.
4. Fiducial target or robot position is so far off nominal that search pattern
cannot locate target (i.e., unlevel picker). This can also generate a T083:
Picker Assembly not level.
