Function Code L: Load/
Unload Test
Approximate Run Time = 30 seconds per loop
Total Number of Loops = 10
Function Code L tests the driv
e's ability to load and unload a tape
cartridge.
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: Even though no data is written during this test, it is
recommended that you use a blank (scratch) cartridge for
this test.
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.
1 Place the drive in Maintenance Mode. For instructions, see Entering
Maintenance Mode on page 48.
2 Press the Unload button on
ce per second until L appears in the
SCD. (If you cycle past the desired code, press the Unload button
once per second until the code reappears.)
3 Press and hold the Unload bu
tton for three or more seconds, then
release it to select the function. The SCD changes to a flashing C.
4 Insert a scratch (blank) data cartri
dge. The SCD changes to a
flashing L and the tape drive runs the tests.
• If no error is detected, the diagnostic will loo
p 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 Fau
lt 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
