Table 5. Diagnostic and maintenance functions (continued)
Function Code 3 - Create FMR Tape
Causes the tape drive to copy its field microcode replacement (FMR) data to a scratch data cartridge.
Attention: If you select this function, the tape drive will overwrite existing data on the 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 3 appears in the single-character display. If you cycle past 3,
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 a scratch data cartridge that is not
write protected (or the tape drive exits maintenance mode). After you insert the cartridge, 3 flashes and the tape
drive copies the FMR data to the scratch data cartridge:
v If the tape drive creates the FMR tape successfully, it displays 0, rewinds and unloads the new FMR tape, and
exits maintenance mode.
v If the tape drive fails to create the FMR tape, it displays 7, unloads the FMR tape, and exits maintenance
mode.
Function Code 4 - Force a Drive Dump
Causes the tape drive to perform a collection (or dump) of data. (A drive dump is also known as a save of the
firmware trace.) The dump (firmware trace) can only be analyzed by IBM.
Note: When an error code displays, a red dot also displays to remind you that a dump already exists. If you
perform Function Code 4, it will overwrite the dump and cause the error information to be lost.
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 4 appears in the single-character display. If you cycle past 4,
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, 4 displays,
followed by 0. The single-character display then goes blank, and the tape drive exits maintenance mode.
An illuminated red dot on the single-character display indicates that a drive dump has been created. To retrieve the
dump from the drive, see Function Code 5 on page 39.
You can also perform this operation when the tape drive is in normal operating mode. Simply press and hold the
unload button for 10 seconds.
