Loading revised firmware via Seagate firmware cartridge
The STT8000A uses flash EEPROM. Flash EEPROM enables you to download new
firmware when revisions to firmware are released. Firmware revisions are released
on specially encoded cartridges that are automatically recognized by these drives.
These firmware revisions are available for qualified OEMs only from Seagate
Technology, Inc.
To load a firmware upgrade tape, follow these steps.
1. Power on the host system and the STT8000A drive. Allow the system boot up
process to reach the point where there is no ATAPI bus activity.
2. Place the firmware upgrade cartridge record switch to the non-record position.
Insert the firmware upgrade cartridge in the drive and observe the amber LED
light on the front of the drive.
3. After the upgrade cartridge is inserted, tape motion begins. The drive LED
flashes on and off. Approximately 15 seconds later, tape motion stops, and the
LED continues to flash.
4. The LED flashes on and off at a steady rate as the firmware upgrade continues.
Approximately 45 seconds later, the drive resets internally, and the tape moves
back and forth, then stops.
5. The LED light will go off and remain off. Double check that the LED remains off .
Make sure that there is not further tape motion. Remove the upgrade cartridge.
6. The firmware is now upgraded to the new revision. The drive is operational and
the new firmware is active. Turning power off at this time does not affect the
firmware revision level.
Note:
Once the firmware upgrade cartridge is inserted in the drive, it is important
that no power interruption occurs while the firmware is loading. DO NOT
POWER OFF THE DRIVE AT THIS TIME. If a power interruption occurs,
the firmware may not be loaded correctly, and the drive may not operate
properly.
If a problem occurs during the firmware loading process, the LED on the front panel
goes out. In that case, the firmware upgrade cartridge may be defective, or the drive
may not be operating correctly.
If after a repeat loading of the firmware cartridge, the same condition is observed,
contact your Seagate sales representative.
Firmware upgrade cartridges are available to qualified Seagate OEM customers.
Contact your Seagate sales representative for information.
