Victor, Radoslaw already mentioned some of the data that rmm records, and I know CA-1 does similar. However, rmm actually now has much more and very interesting data about what is written by the app and what has happened to it in the hardware. For the details you need to be using tapes that report to the host system the correct information...... So that includes IBM drives since 3590, and other manufacturer drives that correctly emulate 3590.
See this section in the rmm MURM http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dgt2r3a0/1.3.11?SHELF=all13be9&DT=20110602105512 This was new capability introduced via an APAR to rmm at the time of TS1140 support - so should be available on all supported releases.
