1 Place the drive in maintenance mode. For instructions, see Entering
Maintenance Mode on page 47.
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
and Messages. The tape drive then unloads the FUP tape, and
exits Maintenance Mode after the cartridge is removed.
Function Code 9:
Display Error Code Log
Function Code 9 displays the last ten error codes, one at a time (the
codes are ordered; the most recent is presented first and the oldest is
presented last). If there are no errors in the log, function code 0 displays
in the Single-character Display (SCD) and exits Maintenance Mode.
1 Place the drive in Maintenance Mode. For instructions, see Entering
Maintenance Mode on page 47.
2 Press the Unload button once per second until 9 appears in the
SCD. (If you cycle past the desired code, press the Unload button
once per second until the code reappears.)
