UPDATING THE FIRMWARE
This chapter explains how to update the tape drive’s PCBA-resident firmware.
C.1 OVERVIEW
Using the tape drive’s front panel and a tape with the updated firmware image,
you can update the tape drive’s PCBA-resident firmware.
CAUTION
If a powerfail occurs during the firmware update process (when the
new image is actually being programmed into the FLASH EEPROMs),
the tape drive’s PCBA will be rendered unusable. When performing
a firmware update, take all possible precautions to prevent power
failure to the tape drive.
C.2 CREATING A FIRMWARE UPDATE TAPE
To update the tape drive’s PCBA firmware, you need a tape cartridge with a copy
of the new firmware image. The firmware image must be byte-written without
compression onto the tape using the appropriate block size as defined in Table C-
1. The image must be “copied” onto the tape instead of using the backup utility.
