In CA 1 rel 14.0 + fixes RO93819 and SO01019 you have an EARL program called TMETPUSE. This will calculate the amount of data on all of the active tapes in the TMC.
You can use the CTAPJCL member called TMSEARL to run this program. You will need to make slight modifications to the JCL to point it to the TMETPUSE member for the SYSIN, and your TMC name for the TAPEDB DD.
In this member the Bytes Used indicates the number of bytes that were actually written to the tape device based on the BytePrc field (BytesUsed = DS Block Count * Blksz * BytePrc).
The Bytes Stored indicates the number of bytes that were actually written to the tape media after compression has been applied in the tape drive or control unit. The CompRatio field is used to develop this count. For example, for a data set with these attributes in the TMC
