Function Code 3: Create FMR Tape
Function Code
3
copies the drive’s field microcode replacement (FMR) data to a
scratch data cartridge.
Attention
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.
1. Place the drive in maintenance mode. For instructions, see “Entering
Maintenance Mode” on page 32.
2.
Press the Unload Button once per second until
3
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 Unload Button for three or more seconds, then release it to
select the function. The SCD changes to a flashing
C
.
4. Insert a scratch (blank) data cartridge that is not write protected (or the tape
drive exits maintenance mode). The SCD changes to a flashing
3
. The tape
drive copies the FMR data to the scratch data cartridge.
Note: If you inserted an invalid or write-protected tape cartridge, error code
7
appears in the SCD. The tape drive unloads the cartridge and exits
maintenance mode.
v
If the tape drive creates the FMR tape successfully, it rewinds and unloads
the new tape, exits maintenance mode, and the tape is ready to use .
v If the tape drive fails to create the FMR tape, it displays an error code. To
determine the error, see Table 15 on page 75. The tape drive then unloads the
FMR tape, exits maintenance mode.
Function Code 4: Force a Drive Dump
Function Code
8
performs a dump of data collected by the drive (this process is
also known as saving a microcode trace).
1.
Place the drive in maintenance mode. For instructions, see “Entering
Maintenance Mode” on page 32.
2.
Press the Unload Button once per second until
8
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 Unload 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. To access the contents of the dump, see “Function Code 5: Copy
Drive Dump” on page 36.
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.
