Hardware addressing in11.31

One of my server has 3 EVA LUNs allocated.Each LUN has 8 paths. Hardware path of 1st LUn is showing as ,
disk 34 64000/0xfa00/0x1 esdisk CLAIMED DEVICE online HP HSV210

Note the lun id part in lunpath hardware path.
For other two LUNs it is showing as ;
disk 20 64000/0xfa00/0x2 esdisk CLAIMED DEVICE online HP HSV210

And the addressing mode for 1st LUN is "Peripheral Addressing" and for 2nd and 3rd is "Flat Space Addressing".
scsimgr is showing LUN ID as 0, 2 and 4 respecively for 1st, 2nd and 3rd LUN.

What is the difference between these addressing methods?
How does it change for the LUNs from the same storage?
How the LUN # (from scsimgr output ) is being assigned?
