About this task
Attention: When drive firmware is updated, do not turn the drive off until the update is complete or the firmware might be lost.
Function code loads drive firmware from a field microcode replacement (FMR) tape. The FMR tape must be created from an LTO Ultrium 8 tape drive with the same host
interface (SAS or Fibre Channel).
Procedure
1. Place the drive in Maintenance mode. For instructions, see Entering Maintenance mode.
2. Press Unload once per second until displays in the SCD. (If you cycle past the wanted code, press Unload once per second until the code reappears.)
3. Press and hold Unload for 3 or more seconds, then release it to select the function. The SCD changes to a flashing , requesting a cartridge.
4. Insert the FMR tape cartridge. The SCD changes to a flashing . The Fault light is ON solid during tape movement and flashing while code is being loaded. The
Ready light is OFF. The tape drive loads the updated firmware from the FMR tape into its erasable programmable read-only memory (EPROM) area.
If the update completes successfully, the tape drive rewinds and unloads the FMR tape, resets itself, and is ready to use the new firmware. The drive
automatically reboots.
If the update fails, the tape drive posts an error code to the SCD. To determine the error, locate the code in Table 1. The drive then unloads the FMR tape and
exits Maintenance mode after the cartridge is removed. Contact IBM technical support for problem determination or machine replacement.
Function code 3: Create FMR tape

About this task
Function code copies the drive's field microcode replacement (FMR) data to a scratch data cartridge. The resulting FMR tape is used only to update the firmware on
other LTO Ultrium 8 tape drives with the same host interface (SAS or Fibre Channel).
Attention: For this function, insert only a scratch (blank) data cartridge or a cartridge that might be overwritten. During the test, the drive overwrites the data on the
cartridge.
Note: If you inserted an invalid tape cartridge, error code or appears in the SCD. If you inserted a write-protected cartridge, or the media has read-only compatibility,
error code appears in the SCD. In either case, the tape drive unloads the cartridge and exits Maintenance mode after the cartridge is removed.
Procedure
1. Place the drive in Maintenance mode. For instructions, see Entering Maintenance mode.
2. Press Unload once per second until appears in the SCD. (If you cycle past the wanted code, press Unload once per second until the code reappears.).
3. Press and hold Unload for 3 or more seconds, then release it to select the function. The SCD changes to a flashing , requesting a cartridge.
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 . The tape drive
copies the FMR data to the scratch data cartridge.
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.
If the tape drive fails to create the FMR tape, it displays an error code. To determine the error, see Table 1. The tape drive then unloads the FMR tape, and
exits Maintenance mode after the cartridge is removed.
Function code 4: Force a drive dump
Edit online
About this task
Function code completes a memory dump of data that is collected by the drive (this process is also known as saving a microcode trace).
Procedure
1. Place the drive in Maintenance mode. For instructions, see Entering Maintenance mode.
2. Press Unload once per second until displays in the SCD. (If you cycle past the wanted code, press Unload once per second until the code reappears.)
3. Press and hold Unload for 3 or more seconds, then release it to select the function. The drive completes the memory dump. The SCD shows , then goes blank,
and the drive exits Maintenance mode. To access the contents of the memory 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. Press and hold Unload for 10 seconds. This action causes the drive to
reboot.
