Firmware Update (From Tape)
7-16 DLT2000/DLT2500/DLT2700 Cartridge Tape Subsystem
g. When the drive code update is complete, the drive resets, and
goes through Power-On Self-Test (POST). The process waits
until the tape is reloaded at beginning of tape (BOT).
h. If the firmware image is valid, the controller's flash EEPROM
memory is automatically updated with the new firmware
image.
i. Whether the firmware update is successful, the subsystem
resets itself. A full, extended scan of the loader takes place. The
scan goes quickly if the firmware update cartridge was the only
tape cartridge in the magazine. If six other cartridges are
present, the scan takes an extra minute or more.
7.4.3.1 Interpreting the Results (DLT2700 Code Update)
Two possible results can occur:
•
The firmware update cartridge is unloaded: this means a successful
update.
On the DLT2700, the cartridge is unloaded from the drive and into the
magazine slot from which it came. If another cartridge is in the
magazine, that next cartridge loads into the drive.
•
The firmware update cartridge is NOT unloaded: this means the update
was unsuccessful.
The subsystem should still be usable, but this depends on why the update
failed. Reasons for failure could be:
1. Power failure
2. Bad image on the tape
3. Broken flash EEPROMs
