Migration cleanup of automatic secondary space management functions is requested on this processing unit while another migration cleanup of automatic secondary space management is running on another processing unit. If this happens, DFSMShsm will not process the migration cleanup on this processing unit since an unexpected result may occur while running two migration cleanups against the same MCDS at the same time.
The second migration cleanup is skipped. The first migration cleanup proceeds.
Do not start a second automatic secondary space management function on any processing unit if automatic secondary space management is currently running.
