Error Description
7650h Unable to detach leader block during recover tape operation when reverse threaded.
7651h Unable to detach leader block during recover tape operation when forward threaded.
7652h Unable to identify cartridge type during recover-tape operation.
7653h The tape thickness reported by the Cartridge Memory is too large or too small.
7654h The tape thickness reported by the CM is invalid and cannot be used.
7655h The full pack radius reported by the CM appears to be invalid and will not be used.
7656h The tape length reported by the CM appears to be invalid and will not be used.
7657h The empty reel inertia reported by the CM appears to be invalid and will not be used.
7658h The empty reel radius reported by the CM appears to be invalid and will not be used.
The front reel is not rotating properly. It is possible that some tape was spilled out from the
7659h
back reel.
765Ah Recovery process was unable to determine the best direction in which to move the tape.
Front reel did not reverse direction after passing through the critical region for threading re-
765Bh
versal.
765Ch Back reel did not stop as expected during a tape recovery process.
765Dh Warning: Leader block demate process resorted to pushing the back reel clockwise.
765Eh Rethreading position time-out during the leader block demate retry process.
765Fh Leader block demate retry process was unsuccessful.
7660h It was necessary to tug the tape to detach the leader block.
7661h Timed out waiting for the required number of layers to overwrap the leader block.
7662h Timed out waiting for the tape to unwrap from the leader block during a reverse thread.
7663h Timed out waiting for a return to the original lock-in position during a reverse thread.
DSP tuning parameters were reloaded into the DSP before a VI-sensor calibration command.
7664h
This is a recovery algorithm.
7665h A special test mode has been enabled that will generate specific faults.
7666h The special test mode has now been disabled. Normal operation will resume.
The front reel is not running in the reverse direction after the tension ramp after passing
7667h
through the critical region during a thread.
The front reel did not reverse direction after passing through the critical region during an
7668h
unthread, step 1.
The front reel did not reverse direction after passing through the critical region during an
7669h
unthread, step 2.
766Ah Timed out waiting for speed to reduce while approaching the critical region during a thread.
