On UN*X systems, use the FTP utility to transfer the binary firmware image. Be

sure to specify “type image” before using the “get” or “put” commands, otherwise

extra characters may be added to the file, causing the image file to be invalid.

The image file should be exactly 1286 * 512 bytes in size.

When making the update tape, copy the image file to the tape media using a

block size as defined in Table C-1, that is dd, ltf, and so on. The tape must be

uncompressed.

C.3 FIRMWARE UPDATE PROCEDURE

This section describes the procedure to update the firmware of the tape drive’s

PCBA. The update requires a cartridge that holds the update firmware image.

Firmware updates from a host are also supported (see the section on the SCSI

command WRITE BUFFER in Chapter 5).

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.
