Logical switches use FID values to establish ISL link - both logical switches must have the same FID.
That preclude connection between two logical switches within single chassis, because they must have differen FIDs.
Q1: What about connection logical switch in chassis A and other switch B working in VF disabled mode, that means physical switch?
Does physical swich have any FID value?
Q2: Can I connect two logical switches from single chassis A to physical switch B ?

Q1: The physical switch should not require a FID address. From the physical switch's standpoint you are simply running an ISL. If you are going to be adding an EX_port ISL from the Logical switch to the physical switch, that changes the game a little.
When you create a FID for the EX port, you must create a different FID from the Logical Switch.
The physical switch (assuming it is in VF disabled mode) would not exist, and not need to.
Q2: Yes, you can. Switch B will think that two different switches are connected.
