Exactly how/why was the SAS cable "knocked out". Is this racked gear? Fix that problem before worrying about the array state, as you may find yourself here again in the future. Bringing the array back up with guess work vs starting a restore now, if you blow the array trying to fix it with mdadm hacks, you can always still run the restore later. Just make sure you do a lot of verification after you bring the arrays back up and they _seem_ fine. Don't trust surface appearances, esp when talking about 30TB of data.
