Industry-standard N_Port ID Virtualization (NPIV) on the z9 is needed if you want to apply zoning and LUN masking (FC access controls) to virtual machines and/or LPARs just as they are for discrete systems. With NPIV, each FCP subchannel, rather than chpid, is assigned a unique WWPN. Matching support in the local FC switch is required. On a z890 and z990 you can use the Linux-based FCP LUN Access Control utility to control guest/LPAR access to WWPNs and LUNs. Even though the other systems and switches see just one WWPN per FC chpid (and no special switch support is needed), the utility instructs the FCP adapter to act as a gatekeeper. Read more about it on ResourceLink at https://www-1.ibm.com/servers/resourcelink/hom03010.nsf/pages/fcpaccumain?opendocument. (You get to this by navigating first to Tools and then selecting "Configuration Utility for FCP LUN Access Control" in the first column.) Alan Altmark z/VM Development IBM Endicott
