The tape volumes needed for the DFSMShsm function cannot be allocated. This message may be proceeded by message ARC1001I or ARC1020I containing the data set name.
All DFSMShsm processing outside of this task continues. If a data set function is processing it fails. If a volume function is processing it continues with the next eligible volume.
Contact your operator to determine the availability of tape volumes needed. Operations should check the ARC0790E message issued to the console for a list of volumes needed for this data set.
