Dear Bob, I feel stupid. The number of I/E slots could be configured from the tape's interface. I reduced their number to just 6 (minimum). Now it's reported correctly: Data Transfer Element 1:Full (Storage Element 70 Loaded):VolumeTag = ACW965L4
Best Regards, Spiros Ioannou 3) Yes, all these slots are reported as I/E. I've seen other posts describing this problem.
