Once you begin this test, the diagnostic test begins the loop sequence. Time the
first loop by pressing
Unload once to stop the diagnostic test after the completion
of the first loop. Then record the time that it takes for the test to complete.
Compare the recorded time with the "Approximate Run Time". If the test runs
successfully but the execution time is longer than the "Approximate Run Time",
run “Function Code F: Write Performance Test” on page 3-17. If the Write
Performance Test fails, replace the media and exit Maintenance Mode.
Press Unload to stop the diagnostic test and exit Maintenance Mode. Pressing
Unload once aborts the test at the end of the current test loop. Pressing Unload
twice aborts the test immediately. Wait for the drive to rewind the tape and unload
the cartridge.
Attention:
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 (for example, Gen2 or WORM
media), error code
J
or
7
appears in the SCD. If you inserted a
write-protected cartridge, or the media has read-only compatibility (for
example, Gen3 media), 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 3-9.
2.
Press the Unload Button once per second until
J
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 Button 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 cartridge. The SCD changes to a flashing
J
and
the tape drive runs the tests.
v If no error is detected, the diagnostic test loops and begins again. To stop
the loop, press Unload for 1 second and release. When the diagnostic test
ends,
0
temporarily appears in the SCD, and the tape drive exits
Maintenance Mode.
v
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,” on page A-1. To clear the error either turn the
power off and then on again, or reboot the drive by pressing and holding
Unload for 10 seconds.
Function Code L: Load/Unload Test
Approximate Run Time = 25 seconds per loop
Total Number of Loops = 10
Function Code
L
tests the drive's ability to load and unload a tape cartridge.
