Function code J: Fast read/write test
Approximate Run Time = 7 minutes per loop
Total Number of Loops = 10
Function code
J
completes tests to ensure that the drive can read from and write to tape.
When 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 30. 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 stops the test
at the end of the current test loop. Pressing Unload twice stops 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, 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 23.
2. Press Unload once per second until
J
displays in the SCD. (If you cycle past the wanted code, press
Unload once per second until the code reappears.)
3. Press and hold Unload for three or more seconds, then release it to select the function. The SCD
changes to a flashing
C
, requesting a cartridge.
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 begin again. To stop the loop, press Unload for
1 second and release. When the loop ends,
0
temporarily displays 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 Table 17 on page 65. 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 = 30 seconds per loop
Total Number of Loops = 10
Function code
L
tests the drive 's ability to load and unload a tape cartridge.
