I would be very interested in who, and with what background, suggested the multiple MDISK approach, as it flies in the face of everything we've been taught by Mom over the years, all the way back to VM/370. (Maybe back to CP-67.)

In the past I have used a userid as a disk holder with MDISKs using DEVNO and MWV. The guests would then LINK to the MDISKs using MW. It has been suggested that I eliminate the disk holder userid and use MDISK statements only. Each guest would then have an MDISK for the same address. For example, MDISK D000 3390 DEVNO D000 MWV Does anyone know if there is any advantage or disadvantage to one way over the other?
