release. When the diagnostic ends, 0 temporarily appears in the
SCD, and the tape drive exits Maintenance Mode.
• 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 A, Error Codes and Messages
. 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 FUP Tape
Function Code 8 erases the firmware update (FUP) data and rewrites
the cartridge memory on the tape. This converts the cartridge into a
valid scratch (blank) data cartridge.
1 Place the drive in maintenance mode. For instructions, see Entering
Maintenance Mode on page 48.
2 Press the Unload button once per second until 8 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 three or more seconds, then
release it to select function 8 . The SCD changes to a flashing C ,
requesting a cartridge.
4 Insert the FUP data cartridge (or the tape drive exits maintenance
mode). The SCD changes to a flashing
8 . The tape drive erases the
firmware on the tape and rewrites the header in the cartridge
memory to change the cartridge to a valid scratch (blank) data
cartridge. The drive then ejects the cartridge and exits Maintenance
Mode.
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.
• If the tape drive creates the scratch tape successfully, it rewinds
and unloads the new tape, exits Maintenance Mode, and the
tape is ready to use.
• If the tape drive fails to create the scratch tape, it displays an
error code. To determine the error, see Appendix A, Error Codes
