• 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 F: Write
Performance Test
Approximate Run Time = 7 minutes per loop
Total Number of Loops = 10
Function Code F performs tests to ensure that th
e drive can read from
and write to tape.
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.
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 F appears in the
SCD. (If you cycle past the desired code, press the Unload button
once per second until the code reappears.)
