SDM is creating the list of cataloged working space data sets that DFSMSdss will use for snapshot operations. The names of these data sets must meet the naming convention specified in z/OS DFSMSdss Storage Administration.
Snapshot operations that require use of working space data sets are delayed until message ANTM6001I is issued.
If any DFSMSdss jobs have received message ADR736E with return code 1805, resubmit the job after message ANTM6001I is issued.
