Your tape management system should be able to tell you that, I'm pretty sure that at least RMM has that information. Otherwise look at the TAPEMAP program from CBTTAPE.ORG file 171. I seem to recall that you need special security access to use TAPEMAP because it reads the physical files of the tape.
Another possibility is to run a IEBGENER with output to a disk dataset, without specifying the output DCB. The lrecl and blksize will be copied, so you can check the DCB of the copied dataset.
