278 Troubleshooting the Tape Library
T079
T079 - Get Operation Failed, Motion OK
Description GUI Description: The robot failed to pick a tape cartridge.
Explanation: The library cannot successfully get a tape cartridge from a
drive, storage, or I/E location. The tape cartridge is still resting in the source
location. The robot is not obstructed in any way and can continue operations
(unlike the case for T003). If the operation was initiated by a host move media,
the move media command has failed with an ASC/ASCQ of 4h/15h/01h
(hardware mechanical positioning error)
Detection Scenarios The picker cannot get a tape cartridge from the source location. It can scan or
touch the tape cartridge to verify that it is present.
Root Causes • Picker has broken fingers.
• Picker has bad calibration, so it is not positioned correctly.
• Picker has bad Y-gears, so it is not at the height it thinks it is at.
• An obstruction that prevents the picker fingers from getting into the tape
cartridge grooves.
• A bad tape cartridge that is jammed and stuck in the slot.
• A damaged slot or drive that will not release the tape cartridge.
Service Resolution
Steps
1 Perform DR076 - Resolve Get Failure
on page 400.
2Use the Details option on the RAS ticket to gather more information
regarding a specific drive, magazine, or slot causing the problem. Inspect
the problem location for any obstruction or media. Remove it, clear the RAS
ticket, and retry another move operation.
3 If using 400G library firmware or later, run the IVT - Picker test using the
Library Tests option accessed through the operator panel.
Note: IVT is optimized for library firmware versions 520G and above and
libraries built after July 1, 2008 (serial numbers with last four digits 8602 and
above).
• If your library was built on or before July 1, 2008, and you are running
firmware version 520G or later, you will not be able to run the IVT test,
even though the selection is available.
• If your library was built on or before July 1, 2008, and you are running
firmware version 500G or earlier, you can run the test, but it is not
recommended because it may produce erroneous results.
Possible CRUs/FRUs Note: Read and perform all resolution steps before dispatching any parts.
Dispatch the first part listed below for replacement. If this does not solve the
problem, dispatch the second part, and so on, in order. Dispatch only one part
(or set of parts) at a time.
1 Picker Assembly (if Model 1 robot is installed) or
Robot Assembly (if Model 2 robot is installed)
2 Y-carriage Assembly (if Model 1 robot is installed)
