Each system (LPAR) has its own unique worldwide port name (WWPN) associated with its own virtual FC adapter. Having the ability to share a single fibre channel adapter among multiple LPARs could save you the cost of purchasing more adapters than you really need.

This means you can connect each LPAR to physical storage on a SAN natively. Another reason to use NPIV is the reduction in VIOS administration overhead.

Therefore, I will not step through the process of creating virtual Fibre Channel (FC) adapters or preparing your environment so that it is NPIV and virtual FC ready.

There are several publications that already discuss the steps on how to configure NPIV using a VIOS, and I have provided links to some of these in the Related topics section.
