Fill a 7-gallon stockpot halfway with water (or use 2 large pots and divide the ingredients between them). Add the seasoning and bring to a rolling boil. Add the whole potatoes to the pot. Allow the water to return to a boil and cook 5 minutes. Add the onions and sausage. Bring the water back to a boil and cook 15 minutes. Add the corn, bring the water back to a boil and cook 10 minutes, or until the potatoes are done.
Add the shrimp, bring the water back to a boil and cook until the shrimp turn pink, about 3 minutes. Drain through a colander; discard the liquid. Serve on newspaper or a platter.
