MVS Dynamic Reconfiguration Management

Richard Cwiakala; Jeffrey Douglas Haggar; Harry M. Yudenfriend

This paper presents an overview of the Dynamic Reconfiguration Management (DRM) function of MVS/ESA™ and its support of the IBM Enterprise System/9000™ family of machines. Dynamic Reconfiguration Management is the ability to select a new I/O configuration definition without needing to perform a power-on reset (POR) of the hardware or an initial program load (IPL) of the MVS operating system. Dynamic Reconfiguration Management allows the installation to add, delete, or modify definitions for channel paths, control units, and I/O devices, in both the software and hardware I/O configurations.
