This phase applies to rebuild and duplexing rebuild processes. When the Rebuild Quiesce phase ends, each connector receives a Rebuild Connect event to indicate that the connector should issue a connect request for the new or duplexed structure. The system allocates the new structure upon receipt of the first connect request; subsequent connect requests allow the issuer access to the newly-allocated structure. Connectors to the structure are notified of other connected users through their event exit. When a connected user has issued its connect request to the new structure, the user can begin reconstructing or propagating its data to the new structure. As each connector completes its processing to transfer data to the new structure, the connector issues a rebuild complete request (IXLREBLD REQUEST=COMPLETE) to indicate the completion to the system.
