This means you can target only the models you can see. If a model is concealed by a fellow unit member or a rock doesn't matter when it comes to LOS.
I'll look carefully at the Eldar codex at home as for the requirements, but I do have the 5th GBB right here for general shootiness...
1) Models in the same unit do not block
LOS (page 16, "Own Unit").
2) Models can always shoot, and be shot at, through members of their own unit without conferring or receiving a cover save (page 22, "Own Unit").
3) Firing through "intervening" units or into area terrain confers a cover save, it does not block
LOS (page 22, "Firing through...").
Basically:
If you can draw a line of site to the target, but the line must pass through a member of his own unit or a member of your own unit, there is no cover save and no
LOS block.
If the line goes through models of an intervening unit or between 2 pieces of area terrain (see picture on p.22) OR if the target is sitting in area terrain (as per the
FAQ), 4+ cover save to each wound.
If the model is completely obscured by a terrain feature or vehicle, then
LOS is blocked.
