DUMMYDS Invalid Dataset Name Parameter

The conversion program saves to a dataset details of all data found in the DFSMSrmm database that is invalid, for example because of invalid dataset or volume information.

The default name for this dataset is DUMMY.RMM.CONVERT.DATASET, but you can use the DUMMYDS parameter to set any name you want.

The conversion program regards a volume as invalid in the following cases:

• The volume is part of a broken chain. This occurs where the volume is recorded in DFSMSrmm as the second volume of a dataset, but there is no corresponding first volume.
• The volume is marked as active, that is, it has either USER or MASTER status in DFSMSrmm, but there is no corresponding dataset for the volume.
