Rebuild Connectivity Requirements

The system by default allows a structure to be rebuilt only when it can ensure the following connectivity levels at the time the rebuild is initiated:

If the rebuild was initiated because of a loss of connectivity, the rebuilt structure will have better connectivity than the connectivity of the set of connectors to the old structure that did not lose connectivity to that structure.
If the rebuild was initiated for any other reason, the rebuilt structure will have equivalent or better connectivity than the connectivity of the set of connectors to the old structure that did not lose connectivity to that structure.

When the reason for the rebuild is other than loss of connectivity, the application or the operator can override this system default by including a keyword, LESSCONNACTION=CONTINUE, on the macro invocation or command. If the new structure cannot be allocated with equivalent or better connectivity than the old structure, and the application or the operator did not specify LESSCONNACTION=CONTINUE, the system does not initiate the rebuild process. For a duplexing rebuild, LESCONNACTION=TERMINATE is assumed.
