During IPL processing, MVS tells the machine to do a store status as part of the next LOAD (IPL) operation under the assumption that the next LOAD *might* be an IPL of SA dump. If it isn't, no harm is done. This function was introduced in MVS/370 SP1.3 as part of the RAS enhancements package for the 3033 processor, to deal with the problem of operators forgetting to do a store status. Unfortunately, VM never implemented this function (unless it was done recently and I didn't hear about it), so you still need to do it manually when running MVS on VM. >>archive end One update: That support was added to z/VM 5.1, which became generally available in September, 2004.
