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 Appendix C,
“Error codes and messages,” on page 63. 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 only for informational purposes. It is not
supported on the 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).
Before selecting this function, attach an LDI or RS-422 wrap plug to the drive LDI
or RS-422 connector (in place of the LDI or RS-422 cable).
1. Make sure that no cartridge is in the drive, and the correct wrap plug is
attached to the RS-422 connector.
2. Put the drive in Maintenance mode. For instructions, see “Entering
Maintenance mode” on page 27.
3. Press the Unload button once per second until appears in the SCD. If you
cycle past , continue to press the Unload button until it displays again.
4. To select the function, press and hold the Unload button for 3 seconds. After
you select the function, flashes and the drive automatically starts 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
diagnostic ends, temporarily appears 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 Appendix C,
“Error codes and messages,” on page 63. 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 8: Unmake FMR tape
Function code erases the field microcode replacement (FMR) data and rewrites
the cartridge memory on the tape. This converts the cartridge into a valid scratch
(blank) data cartridge.
To execute Function code 8: Unmake FMR tape, complete the following steps:
1. Put the drive in Maintenance mode. For instructions, see “Entering
Maintenance mode” on page 27.
2. Press the Unload button once per second until appears in the SCD. (If you
cycle past the desired code, press the Unload button once per second until the
code reappears.)
