T142: Robotics Y-Axis Hardware Failure
Description GUI Description: The robotic Y-axis gear failed to perform proper motion.
Explanation: Movement of the robot assembly along the Y-axis is
accomplished using the Y-carriage assembly, which contains the Y-motor. The
Y-motor has a gear that is attached directly to the motor shaft. Failure or
degradation of this Y-motor gear is the failure mode for this ticket.
Detection Scenarios Robotics firmware reports a specific hardware error identifying the Y-carriage
assembly or Y-Motor hardware as the source.
Root Cause Failure or degradation of the Y-motor gear that drives the robot assembly
along the y-axis.
Possible FRU Replacement Y-carriage Assembly (if Model 1 robot is installed) or Robot Assembly (if
Model 2 robot is installed)
Resolution Perform “M2 Robot Assembly” on page 8-67 for M2 robot assembly or
“Removing the Y-axis/Picker Assembly” on page 8-55 and “Replacing the
Y-axis/Picker Assembly” on page 8-57 for the Model 1.
T143: Unlabeled Cartridge Detected
Description GUI Description: An unlabeled tape cartridge or unreadable tape cartridge
barcode label has been detected.
Explanation: During library initialization, or after a main door closure event,
the library performs an inventory of the entire library. An inventory of
respective magazines is also performed each time an I/O station closes.
These inventory operations use scanner reported barcode label information to
determine element full and empty status. If the library is configured to
perform an "EMPTY SLOT" detection, actually using the teach sensor to
determine if any empty element may hold a cartridge that may not have a
scanner readable barcode label attached, and such an unlabeled cartridge is
found, this RAS ticket is generated to alert of such condition and allow the
user to correct the issue. The system will be able to report full status and
also allow the cartridge to be moved but any cartridge label reference with
be listing "NO_LABEL" on the user interface screens and a SCSI READ
ELEMENT STATUS response will not list label/volser information at all. A
RAS ticket will be generated upon the first occurrence of such unlabeled
cartridge detection; a separate ticket will not be generated for each tape
found.
Detection Scenarios
During "touch" inventory, the teach sensor indicates cartridge presence but
the scanner was unable to read the cartridge barcode label.
Root Cause A tape cartridge does not have a barcode label attached, or the barcode label
is damaged and unreadable.
Possible FRU Replacement None
Resolution Remove and replace the unlabeled tape cartridge.
