We just moved to a DS8100. More research: This *may* be covered by an APAR. Contact the Support Center. This can happen when the base volume has been varied offline. When a device is varied online, the operating system establishes a form of "ownership" via something called the path group id. The device controllers can see the path group id on each device and recognize that the same Entity is at the other end of the wire. A wise concept. When you VARY OFFLINE a device, CP "unregisters" his ownership ("I'm not listening to you!"). The controller requires the base and alias to have the same owner for certain I/O ops. If the base is offline, the path group ids won't match and the controller coughs up an e-hairball. Karl: Why are you using an alias? There shouldn't be a lot of I/O going to the volume that contains the directory, so I can't imagine needing PAV. Alan Altmark z/VM Development IBM Endicott
