The tape drive must be empty of tape medium to allow downloading of an image.
This is a safeguard against accidentally starting a firmware update. If a tape
cartridge is loaded when all or part of a firmware image has been downloaded,
another WRITE BUFFER with Download Microcode mode will be rejected. The
firmware image must be downloaded in integral multiples of 8K bytes.
Any error on a WRITE BUFFER command causes any downloaded image data to
be discarded and the download must be restarted from the beginning.

During the actual reprogramming of the FLASH EEPROM, if any type of
powerfail occurs, or if the reprogramming fails before completion, the tape
drive subsystem becomes unusable and the tape drive must be replaced.

This mode is used to download and save the entire image at once, or to download
the image and save it, or to cause a save operation after the image data has been
downloaded using the Download Microcode mode (without the Save). This mode
of the WRITE BUFFER command causes the image data to be verified and the
Flash EEPROM firmware area to be updated. During the reprogramming of the
Flash EEPROM, the WRITE PROTECT and Drive Activity leds on the drive’s
front panel blinks. Also, when it is updating the EEPROM, it disconnects from the
SCSI bus and will not respond until the update is complete.
When the Save operation is successfully completed, the firmware restarts itself,
causing the Power On Self Test (POST) to be run, and two UNIT ATTENTION
conditions are generated: POWER UP RESET and OPERATING CODE HAS
CHANGED.
