Well, by the time this happens, the planner has already run and generated the best schedule it can think of, which may be larger than the available tape. So it's too late for a warning that would allow you to fix something before the run. And if the dumps actually *don't* fit on tape, you'll get errors to that end. Adding a warning here would only be useful in the narrow margin when the planner has scheduled dumps whose estimates are more than tapelength*runtapes, but where those dumps actually *do* fit on tape at the end of the day. Depending on your actual tape size, that margin may be only a few megabytes wide - easy enough to miss. I wonder if the taper could add warnings to the trace log (such that they would show up in amreport) when it starts bumping DLEs to keep its total under tapelength*runtapes.
