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 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.
Note:
If you inserted an invalid tape cartridge, error code
J
or
7
appears in the SCD. If you inserted a write-protected cartridge,
or the media has read-only compatibility, error code
P
appears
in the SCD. In either case, the tape drive unloads the cartridge
and exits Maintenance Mode after the cartridge is removed.

Place the drive in Maintenance Mode. For instructions, see

Press and hold the
Unload
button for three or more seconds, then
release it to select the function. The SCD changes to a flashing
C
.

Insert a scratch (blank) data cartridge. The SCD changes to a
flashing H. The tape drive runs the tests.
