How much of the IODF-related storage is SQA versus ESQA? Did the OP really mean SQA ie was it actually ESQA that was short?

The stated suspicion was that you systems weren't equal, with most suspicion falling on the IODF. You told us that there were 500 devices in the virtual machine and 516 in the LPAR. You then admitted that the IODF in the virtual machine was far larger than in the LPAR. MVS is going to create a UCB for every device in the IODF, not just for devices that are in the I/O configuration, and SQA isn't big enough to hold it all. Either allocate more SQA or reduce the IODF to match the client configuration.
