Another reason to use NPIV now on your z9 is looking ahead to a future move to a z10: On z9 if you don't use EDEV or NPIV to control access to LUNs you'd use IBM's LUN Access Control utility, but when you get to a z10 you'll find z10 doesn't support LUN Access Control utility so you'd do without LUN Access Control or have to migrate the guests to NPIV or EDEV.
