We did some initial tests with XRC, which I think GDPS depends on?. The z/OS guys found lots and lots of error messages due to the fact that VM does not XRC timestamp it's I/O. (Linux does apparently). They felt it wasn't doable until VM started timestamping.

The zOS team here is actively looking at it (I¹m in the meeting w/ IBM right now), but by the sounds of it, zVM is totally screwed; If something causes zOS to hiperswap, (like a quarterly test of the procedure) zVM is either left standing on DASD running unmirrored, or just crashes because it can no longer access any DASD at all. Is anyone running in this environment? If so, what are the implications to zVM? I really don¹t have a ³comfortable feeling² about this at all. It doesn¹t seem like a well thought-out product, if it won¹t support all of IBM¹s environment... -- .~. Robert P.
