Question:

Sometimes when doing a backup you can get the following messages:

ADSDF102 4106 ADR356E (001)-SB207(01), TASK TERMINATED BY UIM EXIT (06) 
ADSDF102 4106 ADR415W (001)-DTDSC(04), NO DATA SETS WERE COPIED, DUMPED, OR    
RESTORED FROM ANY VOLUME    
ADSDF102 4106 ADR324E (001)-DTDSC(01), THE VOLUME/DATA SET SPECIFIED BY    
DDNAME SYS00032 HAS BECOME UNUSABLE    
ADSDF102 4106 ADR339W (001)-DTDSC(01), I/O ERRORS WERE ENCOUNTERED ON THE FOLLOWING DATA SETS DURING PROCESSING FROM NQM610    
     SYS1.LARGE.DATASET (this is a fantasy name; can be any dataset name) 

or this message in place of SYS1.LARGE.DATASET

ADSDF102 4106 ADR020E (001)-DEVSU(01), DDNAME SYS00050 NOT FOUND
Answer:

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.

  1. 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
         SYS1.LARGE.DATASET
  2. 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.
