Troubleshooting the Tape Library
T001
T001 - Tape Cartridge Stuck in Picker, Motion OK
Description
GUI Description:
A tape is stranded in the Picker Assembly and must be
removed to continue operations.
Explanation:
The robot is not logically expecting to see a tape cartridge in the
picker, but the tape cartridge presence sensor indicates otherwise. The tape
cartridge cannot legitimately be returned to a home slot, nor can it be placed
in a destination slot. The volser may be unknown, the library may be full, or
changing the host inventory is disruptive.
Detection Scenarios
1 The robot becomes enabled after a door open or the library system boots up
and discovers that the tape cartridge present sensor detects a tape
cartridge.
2 The system has tried to recover from a put failure and wants to return the
tape cartridge to a home slot; however, the home slot recovery logic
completes without recovery (home slot is a tape drive or the I/E station is
open or the I/E station is full).
3 The tape cartridge present sensor and sensing circuit is falsely representing
the presence of a tape cartridge.
Root Causes
• Operator did not recover tape cartridge.
• Operator put a tape cartridge in the picker.
• Power loss during move with media, and library logic cannot legitimately
return it to the proper cell.
• Physical contamination such as dust and debris on the sensor gives a “false
full” state.
• Various electrical failures.
Service Resolution
Steps
1 Perform
DR001 - Resolve Picker Cartridge Presence
on page 366.
2 Media may be stuck in the picker. Open the door on the unit and inspect the
picker to see if any media is present. If media is found, remove it, clear the
RAS ticket and retry the original operation.
Possible CRUs/FRUs
Note:
Read and perform all resolution steps before dispatching any parts.

problem, dispatch the second part, and so on, in order. Dispatch only one part
(or set of parts) at a time.
