Table 5-1. Diagnostic and Maintenance Function Codes and Descriptions (continued)
Function Code J - Fast Read/Write Test
Approximate Run Time = 5 minutes
Total Number of Loops = 10
Function Code
J
performs tests to ensure that the drive can read from and write to tape.
The diagnostic loops ten times. Press the eject button to stop the diagnostic and exit maintenance mode. Pressing
the eject button once will abort the test at the end of the current test loop. Pressing the eject button twice will abort
the test immediately.
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.
1. Ensure that there is no cartridge in the drive.
2. Press the eject button three times within an interval of 2 seconds. The fault LED becomes solid amber, which
means that the drive is in maintenance mode.
3. Press the eject button once per second until
J
appears in the single-character display. If you cycle past
J
,
continue to press the eject button until it reappears.
4. Press and hold the eject button for three or more seconds, then release it to select the function. The
single-character display changes to a flashing
C
.
5. Within 60 seconds, insert a scratch data cartridge that is not write-protected.
Note:
If you wait longer than 60 seconds to load a cartridge, the drive will automatically exit maintenance
mode. If you insert a write-protected cartridge, the tape drive will display a
P
and retain the cartridge until it
is manually ejected. Once the cartridge is ejected and removed, the tape drive will exit maintenance mode.
After you insert the cartridge, the single-character display changes to a flashing
J
, and the tape drive runs the
tests.
Note: If you inserted an invalid cartridge, error code
7
appears in the single-character display. The tape drive
retains the cartridge until it is manually ejected. Once ejected, the tape drive exits maintenance mode.
v If no error is detected, the test will loop and begin again. To stop the loop, press the eject button for one second
and release. When the loop ends, the drive rewinds, unloads the tape, and exits maintenance mode.
v If an error is detected, the fault LED flashes amber, then the tape drive posts an error code to the single-character
display. To determine the error, locate the code in “Descriptions and Corrective Actions” on page 5-10. Once the
cartridge is manually ejected and removed, the tape drive exits maintenance mode.
