• If the tape drive creates the FUP 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 FUP 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 4: Force
a Drive Dump
Function Code 4 performs a dump of data collected by the drive (this
process is also known as saving a microcode trace).

Entering
Maintenance Mode on page 48.
2 Press the Unload button on
ce per second until 4 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 Unlo
ad button for three or more seconds, then
release it to select the function. The drive performs the dump. The
SCD shows 0, then goes blank, and the drive exits Maintenance
Mode. To access the contents of the dump, see
Function Code 5:
Copy Drive Dump on page 52
Note: You can also force a drive dump when the tape drive is in
normal operating mode. Simply press and hold the Unload
button for ten seconds. This causes the drive to reboot.
Function Code 5: Copy
Drive Dump
Function Code 5 copies data from a drive dump (captured in Function
Code 4) to the beginning of a scratch (blank) data cartridge.
Caution: For this function, insert only a scratch (blank) data
cartridge or a cartridge that may be overwritten. During
the test, the drive overwrites the data on the cartridge.
