During merge processing, the DSNINDEX is updated to reflect the new volume of residence as each data set is successfully copied to its new volume. If the merge step terminates abnormally, the ARCHVOLS file record for the current output will have incomplete statistical fields. These are normally updated during archive CLOSE processing. The absence of this information will not prevent the restoration of a data set from the output, nor will it cause any problems during processing of the output in a subsequent merge.
If desired, you can correct the incomplete statistical information in the ARCHVOLS record by scratching it from the files data set (RESET command), then using the REBUILD command to reconstruct the ARCHVOLS record from the archive data set, whether on tape or disk.
Merge processing can be restarted by submitting the same JCL as used in the failing job. If the same selection tests are specified, processing will continue with the data set being processed when the failure took place.
As noted previous, CA Disk considers any tape it has written to be a good tape, even though an abend can have occurred during processing. If you are using a tape management system in your installation, care should be taken to see that it does not treat such tapes as scratch tapes. (Note that this is not an issue if you use the EDM option of your tape management system.) Some tape management systems can default to giving abend tapes a one-day retention period. If this is the case, you should either change your tape management system to not do this for CA Disk tapes, or take clerical means to properly save the CA Disk tapes after an abend.
