NPIV Overview
►N_Port ID Virtualization (NPIV) is a fibre channel industry standard
method for virtualizing a physical fibre channel port.
►NPIV allows one F_Port to be associated with multiple N_Port IDs,
so a physical fibre channel HBA can be shared across multiple guest
operating systems in a virtual environment.
►On POWER, NPIV allows logical partitions (LPARs) to have
dedicated N_Port IDs, giving the OS a unique identity to the SAN,
just as if it had a dedicated physical HBA(s).
VIOS v1 : All SAN disks are viewed as SCSI Devices.
VIOS v2 : All SAN disks are viewed thru WWPN.
