An incompatibility can exist between DFSMShsm and the TSO DELETE command or the access method services DELETE SCRATCH command if the data set being renamed has migrated.

If you do not provide a FILE DD statement for the data set being deleted or you provide a FILE DD statement and do not specify the data set name, DFSMShsm successfully recalls and deletes the data set. If you provide a FILE DD statement to allocate the volume and supply the data set name on this DD statement, a message is issued specifying that dynamic allocation has detected a discrepancy between the volume specified with the FILE DD statement and the volume recorded in the computing system catalog, which in this case is MIGRAT. If the volume specified on the FILE DD statement is the same one from which the data set last migrated, the data set is scratched. If the volume is not the same, the data set is not scratched. In either case, the data set remains cataloged.
