Wait a minute....whoooo there... I was under the impression that the difference between a Ficon card and a FCP card was the microcode. AND a single card can not be used for both FICON and FCP connections.
However, the following from the FCP LUN Access Control utility seems to say the opposite: "A zSeries 990 or 890 system with licensed internal code driver 55 and any required patches, and at least one FICON® Express card with an associated port configured as an FCP Channel in the IOCDS " OK, I'm reading this as one port of the 4 ports on my FICON adapter can be configured as a FCP Channel. Is that correct? We currently have a single FICON card to our DS6800. We are going to acquire a second FICON card for reduncey and connect it to the DS6800. I was going to take a port from each card and connect it to a proposed VTS. Then I needed two FCP cards, for reduncy, for connection to the FC SAN thingie. I can easily afford to take a port from each of my FICON cards for the FCP function, therefore eliminating the cost of the dual FCP cards. So, is that something I can do?

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.
