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. Table C-1 Block Size Used for Firmware Update Tape
