In which case we can't use FILECOPY?
Filecopy has an issue with a few applications. The function of Filecopy is to take single or multiple file tapes and merge them together. Some applications do not use standard OS file labels when data is added to the tape. They keep track of the volser, the starting block number of your data, and how many blocks of data you have. DFHSM is one example that operators in this type of file structure. DFHSM volumes are tracked as an EDM within tape management and second information is not stored.
Applications that should not be used with Filecopy are as follows:
- Foreign volumes to CA TLMS / CA1.
- DFHSM backups.
- IBM/Tivoli ADSM (TSM) tapes.
- IBM DB2 tapes (if DB2 doesn't catalog them).
- SAS tapes that are multi-volume.
- CA-Dispatch (can be used with TAPECOPY).
- Any datasets identified in the EDM member of PPOPTION.
