[. . . ] Appendix C 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 C1. [. . . ] When performing a firmware update, take all possible precautions to prevent power failure to the tape drive. Make sure you have a DLTtape that bears the firmware image of the required revision level copied to it. Put the tape drive into the firmware update mode. To do this: a) Remove any cartridge in the target tape drive and close the handle (down position). b) Press the UNLOAD button on the drive front panel and hold the button until the WRITE PROTECT indicator begins blinking (approximately six seconds). This indicates that the tape drive has recognized your request for firmware update mode and is waiting for the sequence to complete. C-2 Quantum DLT 7000 Tape System Appendix C: Updating the Firmware NOTE If the WRITE PROTECT indicator does not blink, check that: 1. The drive handle is in its down position. c) Release the UNLOAD button, then press the UNLOAD button again within four (4) seconds. The second press should take less than one (1) second. d) The TAPE IN USE and the WRITE PROTECT indicators will blink. This indicates that the tape drive recognizes that the firmware update mode has been selected. If you are unsuccessful in selecting the firmware update mode (if, for example, pressing the UNLOAD button the second time requires longer than one [1] second), the WRITE PROTECT indicator will stop blinking within several seconds. If the drive and controller PCBA are not communicating properly, you cannot select the firmware update function. Once the firmware update mode has been successfully selected, insert the cartridge with updated firmware image into the drive. The drive then: · · · Automatically reads the cartridge. The tape will move for a few minutes performing calibration and directory processing before any data is read. [. . . ] The firmware update cartridge is NOT unloaded. The tape drive subsystem may still be usable. Failure may be a result of: · · · · Power failure Bad firmware image on the tape Non-functioning FLASH EEPROMS.
