M204.0150
M204.0150 Read past beginning of RESTART stream
Model 204 has encountered an end-of-file (EOF) condition while reading the restart stream backwards during the second pass of the roll back. An EOF condition should not occur at this point since a valid stopping point was determined during the forward scan of the data set. This error condition is most often caused by a multi-volume restart stream. Model 204 does not support multi-volume checkpoint data sets, since it uses the BDAM access method to read the file backwards. BDAM assumes an EOF condition whenever it reaches a volume boundary.
System manager response: Copy the restart data set (or stream members) to a tape data set or to a single-volume disk data set and rerun the job with the remaining JCL intact.
Operator response: Notify your system manager that this error has occurred.
