One rod, possibly two. I typically install just one for such an application. Your inspectors may enforce two.

1/2" non-ferrous, or 5/8" steel/iron coated.

#6 is all that is required to a ground rod(s) alone.

for subpanel most common to use one ground rod but few area might requried 2 rods but keep in your mind that the netrual and ground wires are kept separted.

#6 is very common and you should have no trouble with this but i will check with your inspector for latest issuse with ground rods it might be little diffrent other wise it pretty uniform on this issuse

Merci , Marc
