Table 5. Diagnostic and maintenance functions (continued)
Function Code 8 - Convert FMR Tape to Scratch Tape
Causes the tape drive to erase the field microcode replacement (FMR) data on a scratch data cartridge and rewrite
the cartridge memory on the tape. This turns the cartridge into a valid scratch data cartridge.
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the unload button three times. The status light becomes solid amber, which
means that the drive is in maintenance mode.
3. Press the unload button once per 1.5 seconds until 8 appears in the single-character display. If you cycle past 8,
continue to press the unload button until it redisplays.
4. To select the function, press and hold the unload button for 3 seconds. After you select the function, C flashes.
When C flashes, the drive is waiting for a cartridge. Within 60 seconds, insert the FMR cartridge (or the tape
drive exits maintenance mode). After you insert the cartridge, 8 flashes, the tape drive erases the firmware on
the tape, then rewrites the header in the cartridge memory to change the cartridge to a valid scratch data
cartridge:
v If the operation is successful, the tape drive displays 0, rewinds and ejects the newly converted scratch data
cartridge, and exits maintenance mode.
v If the operation is not successful, an error code displays. To resolve the error, locate the code in Table 8 on
page 49.
Function Code 9 - Display Error Code Log
Causes the tape drive to display the last 10 error codes, one at a time (the codes are ordered; the most recent is
presented first and the oldest (tenth) is presented last).
1. Make sure that no cartridge is in the drive.
2. Within a 1.5-second interval, press the unload button three times. The status light becomes solid amber, which
means that the drive is in maintenance mode.
3. Press the unload button once per 1.5 seconds until 9 appears in the single-character display. If you cycle past 9,
continue to press the unload button until it redisplays.
4. To select the function, press and hold the unload button for 3 seconds. After you select the function, press the
unload button to view the most recent error code. Press the unload button again to view successive error codes.
If you press the unload button for 3 seconds after the tenth error code displays, 0 displays (if there are no errors
in the log) and the drive exits maintenance mode.
