saurabh khandelwal, The sources of information include the 3494 Library Manager, DFHSM and your tape management system. Each will have its own view about what data is in the library. 3494 LM will know what data is valid, but some of this may be on tapes already expired. You can ask 3494 for details of what it knows - tools include the user interface and the BVIR utility. See IBM White paper for 3494 BVIR. DFHSM will know what volumes are in the 3494 and can tell you how much valid data is on each - it tracks a percentage valid data to aid with recycling. Your tape management system should support reporting on non-scratch (and scratch too if you wish) volumes and be able to tell you data set size and maybe even compression ratios depending on your release and product. For example, with rmm you can use the report generator to create a custom report from one of the samples quite easily that shows how much data is on volumes in the library. See Rexx based report REPORT05 which includes data set size, and a similar report from report generator EDGGR05. You could make an assumption about compression ratios if necessary. I recently did such a report for a client and the ICETOOL very readily gave a total size of all application data at the bottom of the report.
