Never mind. I solved it.
1. Renamed folders with img & swdsk files.
2. Created new lun´s in appliance with the same name as on the old one.
3, Delete the lun-folder and content that got created.
4. Rename the Lun folders back.
5. Restart appliance.

Hi. I did initially set up starwind VSAN on Trial license to test it out. When i then was satisfied and wanted to apply the free license i didn´t allow me to. Telling me i need to setup a new one.. So, i set up a new appliance and applied the free license. All good. I had the storage controller pass...
