Function code 8: Unmake FMR tape

Edit online

About this task

Function code 8 erases the field microcode replacement (FMR) data and rewrites the cartridge memory on the tape. This action converts the cartridge into a valid scratch (blank) data cartridge.

Procedure

  1. Place the drive in Maintenance mode. For instructions, see Entering Maintenance mode.
  2. Press Unload once per second until 8 appears in the SCD. (If you cycle past the wanted code, press Unload once per second until the code reappears.)
  3. Press and hold Unload for 3 or more seconds, then release it to select function 8. The SCD changes to a flashing C, requesting a cartridge.
  4. Insert the FMR 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 Table 1. The tape drive then unloads the FMR tape, and exits Maintenance mode after the cartridge is removed.
