Function Code 1: Run drive diagnostics
About this task
Approximate Run Time = 20 minutes per loop
Total Number of Loops = 10
Function Code
1
runs tests that determine whether the drive can properly load
and unload cartridges and read and write data.
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.
Record the time 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
significantly longer than the approximate run time, run “Function Code F: Write
performance test” on page 30. If the Write Performance Test fails, replace the
media.
