A backup command has been issued for a data set and DFSMSdss is the data set data mover. The DFSMSdss DUMP command has been issued to move the data set. When this message is issued, the corresponding DFSMSdss messages should be consulted. The DFSMSdss messages with prefix ADR are listed in the backup activity log for this failure. The data set name is contained in the preceding ARC1001I or associated ARC0734I message. The value of the last DFSMSdss message number issued for the highest severity error encountered during DFSMSdss processing is also in the ARC1001I or ARC0734I message. In some cases the return code is other than the DFSMSdss message number. These cases are as follows:

1. If the value of this return code is 9999, DFSMSdss has abnormally ended (abended) and DFSMShsm could not determine the final DUMP return code. The DFSMSdss messages must be used to determine the cause of the failure.
2. If the value of this return code is 9990, then it is a result of an abend in DFSMSdss.
