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).
1. Place the drive in Maintenance Mode. For instructions, see “Entering
Maintenance Mode” on page 72.
2. Press the Unload Button once 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 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, and the drive exits Maintenance Mode. To access the contents of the
dump, see “Function Code 5: Copy Drive Dump.”
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.
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.
Note: If you inserted an invalid tape cartridge (Gen1 or WORM media, for
example), error code 7 appears in the SCD. If you inserted a write-protected
cartridge, or the media has read-only compatibility (Gen2 media, for
example), error code P appears in the SCD. In either case, the tape drive
unloads the cartridge and exits Maintenance Mode after the cartridge is
removed.
1. Place the drive in Maintenance Mode. (For instructions, see “Entering
Maintenance Mode” on page 72.) Index through the Maintenance Mode options
until 5 is displayed on the SCD. Press and hold the Unload Button for three
seconds to select Function Code 5. After selecting Function Code 5 the SCD will
display option 5 - 1. Press the Unload Button within 5 seconds to make a
different selection. If no other selection is made, the drive will perform option 5
- 1.
2. Press the Unload Button once per second to cycle through the following
functions:
v 5 - 1 : copy dump to tape; clears RAM dump
v 5 - 8 : copy dump to flash memory; clears RAM dump
v 5 - 3 : erase flash memory
v 5 -0 : no function
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 one of the above functions.
4. If you selected 5 - 0 the drive will exit Maintenance Mode. If you selected 5 - 8
or 5 - 3 the SCD will change to a flashing 5 while the procedure is being
