GE LightSpeed VCT (VCT64): SystemState backup cannot be saved
What happened
In this case the engineers could not save the SystemState backup on a GE LightSpeed VCT host: no external SCSI tower was available, the host DVD drive did not work for SystemState, and the USB SystemState tab was missing from the GUI.
What was checked
- Attempted a SystemState save through the standard GUI
- Tried the host DVD drive as the backup target
Cause
No root cause was confirmed in the case; on this host the standard backup paths (SCSI tower, DVD) were unavailable and the GUI did not expose the USB option.
What was done
The SystemState was saved to a USB flash drive with the manufacturer's system-state service utility; this step was a procedure from the manufacturer's service documentation, done by authorised personnel. Discs could still be read with an ordinary reader. For a software reinstall, the engineers reported two workable options: enter the configuration parameters manually or fit a working read-only drive (it reads discs but does not write).
Safety
Power down and isolate the host computer and take anti-static precautions before opening it or swapping drives, and confirm the scanner passes its normal checks before it is returned to use.
Lesson: Know in advance which SystemState backup paths each configuration you service actually offers, before you urgently need one.
