The structure allocated for this duplexing rebuild could not be made failure isolated with respect to the old structure. This is not an optimum use of duplexing since failure of a processor with both coupling facility LPARs in it would result in the loss of both structures.
The duplexing rebuild continues.
Notify the system programmer.
Review your coupling facility configuration. When possible, duplex failure isolation is recommended.
