1. Put the drive in Maintenance mode. For instructions, see “Entering
Maintenance mode” on page 25.
2.
Press the Unload button once per second until
E
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 3 or more seconds, then release it to
select the function. The SCD changes to a flashing
C
requesting a cartridge.
4. Make sure that the write-protect switch on the cartridge is off, then insert the
cartridge (or the tape drive exits Maintenance mode). The SCD changes to
flashing
E
. The tape drive runs the tests.
v
If no error is detected, the diagnostic will loop and begin again. To stop the
loop, press the Unload button for 1 second and release. When the loop ends,
0
temporarily appears in the SCD.
v
If an error is detected, the status light flashes amber and the drive posts an
error code to the SCD. To determine the error, locate the code in Appendix C,
“Error codes and messages,” on page 59. To clear the error, either turn the
power off and then on again, or restart the drive by pressing and holding the
Unload button for 10 seconds.
Function code F: Write performance test
Approximate Run Time = 5 minutes per loop
Total Number of Loops = 10
Function code
F
performs tests to make sure that the drive can read from and
write to tape.
Press the Unload button to stop the diagnostic and exit Maintenance mode. Press
the Unload button once to abort the test at the end of the current test loop. Press
the Unload button twice to abort 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 can be overwritten. During the test, the drive overwrites the data on the
cartridge.
Note: If you inserted an invalid tape cartridge (for example, Gen 2 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, Gen 3 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.
To execute Function code F: Write performance test, complete the following steps:
1. Put the drive in Maintenance mode. For instructions, see “Entering
Maintenance mode” on page 25.
