Phases for User-Managed Processes

The rebuild and duplexing rebuild processes involve a series of established phases, during which all active connectors to the structure coordinate their activities through MVS™. The responsibility for managing the structure and its contents during these phases is that of the connector to the structure. The phases are:
  • Rebuild Quiesce Phase
  • Rebuild Connect Phase
  • Rebuild Duplex Established Phase
  • Rebuild Cleanup Phase

Connectors enter and leave each of these phases based on event notification through their event exits. The events indicate to the connected user the start or completion of a specific phase of the rebuild process. Connected users must respond to some, but not all, of these events.

A brief description of each of the rebuild phases follows:
