• 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

Function Code H: Test
Head
Approximate Run Time = 12 minutes per loop
Total Number of Loops = 10
Function Code H
performs tests to ensure that the tape drive's head
and tape-carriage mechanics work correctly.
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
Code F: Write Performance Test
on page 59. 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.
