T004 - Put Operation Failed, Tape Back In Source Location, Motion OK
Description GUI Description: The robot failed to place a tape cartridge to a destination
slot but recovered the cartridge to an alternate location.
Explanation: The library cannot successfully put a tape cartridge into the
intended target tape drive, storage slot, or I/E station location. The library has
successfully returned the tape cartridge to the source location. Fundamental
servo control appears to be OK.
Detection Scenarios Put is not successful and put recovery is not successful at the destination
element. Recovery logic has allowed the tape cartridge to be returned to the
initial source location. If the operation was initiated by a host move media, the
move media command has failed with a SK/ASC/ASCQ 4h/15h/01h.
Root Causes • Magazine is damaged, wrong type, cell is blocked, cartridge is not clipped in
and seated correctly.
• Calibration problem.
• Picker offset problem.
• Destination cell full with labeled tape cartridge (invalid inventory).
• Destination cell is full with tape cartridge that has damaged label or is
unlabeled or has an intermittently readable label.
• A variety of picker problems such as slipping gears, encoder issues, etc.
