I reran?it on a different machine, and the MIGRATE jobs went through just?fine. I had some trouble getting the newly built 190 pack IPLd the first time around, and it's entirely possible that things were left with the 280 tape in the wrong position.
I'm going through the rest of it now. I don't expect any trouble, but we'll see.
Looking at uploaded listing of the failure, it would appear to be a tape positioning issue, although I do not understand why it occurred. It will take a bit of time for a longer response.??
