Update Tape Drive Firmware from FMR Tape: Loads
updated firmware from a field microcode replacement
(FMR) tape.
“Function code 2: Update drive firmware
from FMR tape” on page 27
3
Create FMR Tape: Copies its field microcode
replacement (FMR) data to a customer-supplied scratch
(blank) data cartridge.
“Function code 3: Create FMR tape” on
page 28
8
Force a Drive Dump: Performs a dump of data (also
known as saving a microcode trace).
“Function code 4: Force a drive dump”
on page 28
5
Copy Drive Dump: Copies data from a drive dump
(captured by using Function code 4) to the beginning of
a customer-supplied scratch (blank) data cartridge,
copies a drive dump to flash memory, or erases a dump
from flash memory.

Insert Cartridge into Tape Drive: This function cannot
be selected by itself, but is a part of other maintenance
functions (such as Run Tape Drive Diagnostics and
Create FMR Tape) that require a tape cartridge to be
loaded.
