• If no error is detected, the diagnostic will loop and begin again.
To stop the loop, press the Unload button for one second and
release. When the diagnostic ends, 0 temporarily appears in the
SCD, and the tape drive exits Maintenance Mode.
• If an error is detected, the Fault light flashes and the drive posts
an error code to the SCD. To determine the error, locate the
code in Appendix A, Error Codes and Messages . To clear the
error either turn the power off and then on again, or reboot the
drive by pressing and holding the Unload button for 10
seconds.
Function Code J: Fast
Read/Write Test
Approximate Run Time = 7 minutes per loop
Total Number of Loops = 10
Function Code J performs tests to ensure that the drive can read from
and write to tape.
Once you begin this test, the diagnostic begins the loop sequence. Time
the first loop by pressing the Unload button once to stop the diagnostic
after the completion of the first loop, then record the time it takes for
the test to complete. Compare the recorded time with the “Approximate
Run Time” above. If the test runs successfully but the execution time is
significantly longer than the “Approximate Run Time”, run Function
Code F: Write Performance Test on page 58. If the Write Performance
Test fails, replace the media and exit maintenance mode.
Press the
Unload button to stop the diagnostic and exit maintenance
mode. Pressing the Unload button once will abort the test at the end of
the current test loop. Pressing the Unload button twice will abort the
test immediately. Wait for the drive to rewind the tape and unload the
cartridge.
Caution: For this test, insert only a scratch (blank) data cartridge or a
cartridge that may be overwritten. During the test, the
drive overwrites the data on the cartridge.
