Function Code
6
performs a check of the host interface circuitry and host
connector on the drive.
1. Make sure that the host interface wrap plug is connected to the host interface
connector at the rear of the drive.
2. Place the drive in Maintenance Mode. For instructions, see “Entering
Maintenance Mode” on page 3-9.
3. For SAS drives,
a. press the Unload Button once per second until
6
appears in the SCD.
Index through the Maintenance Mode options until [6] is displayed on the
SCD. Press and hold the Unload Button for three seconds to select Function
Code 6. After selecting Function Code 6 the SCD will display option [6]-[1].
Press the Unload Button within 5 seconds to make a different selection. If
no other selection is made, the drive will perform option [6]-[1].
b. Continue to press the Unload Button once per second to cycle through the
following functions:
v
6
-
1
: test the primary SAS port
v
6
-
8
: test the secondary SAS port
v
6
-
3
: test both primary and secondary SAS ports at the same time
(requires a wrap plug in both ports)
v
6
-
0
: exit
c. Press and hold the Unload Button for three or more seconds, then release it
to select one of the above functions. The drive automatically starts the test.
If you cycle past the desired code, press the Unload Button once per second
until the code reappears.
4. The SCD will display a flashing
6
during the test.
v 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 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 A,
“Error Codes and Messages,” on page A-1. 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 7: Run RS-422 Wrap Test
Approximate Run Time = 10 seconds per loop
Number of Loops = This test runs until stopped by pressing the Unload Button.
Note: This function is described here for information only. It is not supported on the
TS2240 Tape Drive.
This test causes the drive to perform a check of the circuitry and connector for the
RS-422 interface. This connector supports the Library Drive Interface (LDI) and the
Automation Drive Interface (ADI).
