For Volume you have 5 passes available in render passes rollout:
Volume, Mask, Emission, ZFront, ZBack

I 'm aware of that. I looking for a way to bake normal of the volume ... may be i need a three rgb lights setup to get it or ask for a new feature volume normal pass ...

Looks like you need to ask for it. This is a core engine feature so it's better to ask somewhere here:
