Before providing a response to the Rebuild Switch event, connectors must quiesce their use of the old structure. See Completing Outstanding Structure Requests for information about quiescing the use of a structure. New connectors who connect while the switch is in progress are notified through the Connect answer area and are expected to participate by connecting to the new structure. See Handling New Connections During a User-Managed Rebuild Process. As connectors respond to the Rebuild Switch event with the IXLREBLD REQUEST=DUPLEXCOMPLETE request, the system invalidates both their old and new tokens used to access the structure. When all connectors have responded to the Rebuild Switch event, the system enters the Rebuild Cleanup phase to complete the rebuild process.
