This is an informational message that is issued by SMS during the allocation of a data set that is intended to be the target of a fast replication operation. The caller indicated that selection of fast replication eligible volumes was ‘preferred’. Since ANTRQST QFRVOLS detected an error, SMS will continue the allocation request while ignoring the fast replication preference. Refer to the ANTRQST section in z/OS DFSMS Advanced Copy Services for information on the QFRVOLS return code, reason code and RETINFO.
