Robin, Do you have a tape management system? CA1 TLMS RMM? If not, then you would need to read the labels on the tape to get this information. Or you will need to add other processes to your environment to gather the information. Some of the information may be in SMF data records. Check out the DAF Utility on the CBTTAPE.ORG to look at different type of Assembler Coding for SMF records that might contain your information.
