Updating Firmware From a Tape Cartridge

4. Press and hold the Display Mode button for about five seconds until the SCSI ID SEL
message displays.
5. Press and hold the Load/Unload button until the SCSI ID SEL message starts to flash.
Immediately release the button, and then press it again. The CODE UPDATE
MODE message now displays.
6. Press the Open button twice to open the magazine door. Load the magazine into the
stacker and close the door. Wait until the elevator stops scanning the magazine.
7. Press the Load/Unload button to load the code update tape into the tape drive.
If the firmware is already at the same level as the code on the tape, the DLT2500XT
stacker does not go through the update process. If the firmware is not at the same
level as the code on the tape, the drive code goes through a five-minute update.
Caution: Never turn off power to the DLT2500XT tape drive while the firmware is
being updated. Doing so interrupts the update process, and can damage the unit.
During the update, the drive automatically reads the tape and examines the data.
Calibration and directory processing cause the tape to move for a few minutes
before data is actually read. The drive verifies that the data is a valid DLT2500XT
code image.
When the drive code update completes, the controller’s FOASH EEPROM memory
is updated with the new code image. The drive resets, goes through the POST, and
the code update cartridge is returned to the magazine. The LDR RDY message
displays.
If the code update succeeds, the stacker resets itself. A magazine scan takes place.
8. Press the Open button and remove the magazine. Remove the firmware update tape.
If the firmware cartridge does not unload from the drive and load into the magazine, the
update failed. The drive may reset and the ERR UNK message may display. The stacker
should still be usable, but might require service (depending on why the unit failed).
The three most probable reasons for a DLT2500XT stacker’s failing to complete step 7 are
• power cutoff to the DLT2500XT stacker during the update process
Obtain a new update tape or repeat the upgrade process.
• FLASH EEPROM malfunction
Contact your service provider.
• bad or corrupted data on the update tape cartridge
