> You normally don't see this, but this still does not mean it cannot occur. Were the devices really "offline"?
I do not believe they were "offline" in the system (another thing to check during the test!), but they were offline in the real world. > The UCB Online, Alloc, Busy etc. indicators are independent bits, that do not have a fixed relationship, however z/OS ensures that things happen in a certain order and so there are combinations of bits that you will probably never see. However, you are in an abnormal situation, so you might see rare combinations now. > OLTEP e.g. was one application that allocated an offline device and so the UCB status was really and correctly offline/allocated. GDPS Hyperswap does it, too. > Did you try a V xxx,ONLINE as indicated by IOS002A? This should simulate the I/O interrupt the system is waiting for. I don't believe anyone has done it. Another thing to check. Thank you for your input.
