REASON FOR ERROR:
What seems to have occurred, is that CA-DISK encountered an end-of-volume condition on the tape being written, whereby the data set that is just being backed up is not the first data set on the volume. Since CA-DISK does not spill data sets to follow-up volumes if they are not the first data set on a volume, the operation was stopped with the message:
TASK TERMINATED BY UIM EXIT (06)
This is correct processing, and does not normally mean that data was lost.
- For LARGE data sets:
The following action are then to open a new volume, and backup the dataset.
In the continuation of the job, you will most likely find this message:
ADR454I (001)-DTDSC(01), THE FOLLOWING DATA SETS WERE SUCCESSFULLY PROCESSED
- For ADR020E message, review the Ca Disk report messages and if you see that one:
DSDM928 3825 DEVICE TYPE=(3490E,CART) CAPACITY=2,000MB ADJUSTED TO 8,000MB ES
T FOOTAGE=2,716 ADJUSTED TO 10,864
It means that CARTPRCT is not at its default value of 100 but more. Here it was at 400.
Once this is modified to match the tape size reality the job will no longer send the UIM EXIT (06) message and all will work fine.
The reason is that Ca Disk calculate now correctly space allocation on tape and not enter to multi-volume which makes DFDSS to fail on its ESTAE processing.
In summary, the backup run has not any data lost, and all the data sets were backed up successfully.
