I have gone through one of the doc here and able to grasp the above points
Hope we need to shed some more light to get ur things done

Volume groups other than rootvg normally use virtual SAN disks called vpaths.
The system-side SAN attachment is done through 2 Fibre Channel PCI adapters, connected to 2 independent SAN fabrics. The logical disks on the SAN are attached to each fabric via 2 storage paths, totaling to 4 paths from the host to each LUN.
Each path to a LUN is seen by AIX as a fiber channel disk device
The Subsystem Device Driver (SDD) groups all paths to the same LUN into a multipath virtual device (vpath) which is accessible for IO operations [MPIO] as long as at least one of the component paths is available.
