I would think that if this DS8100 was already being used by this box, then the CHPID and PATHs are already defined. If this is a new controller for you, then you need to do the DEFINE for the controller using the existing paths.
In all cases, you would have to do the DEFINE device(s) for the new volumes. Then, you can vary on the devices and be off and running. When done, be sure to update your IOCP and put it in the next slot. Otherwise a Power On Reset, will loose any dynamically defined IOCP stuff. Tom Duerbusch THD Consulting >>> "Frank M.

Our Z/OS z10 system has them defined and is working with them quite nicely. Our z890 z/VM system doesn't have them in its IOCP. I've checked the z/VM system using CP Q DYN STAT and discovered it does allow dynamic io reconfiguration. So, my question is how do I get the new dasd online to z/VM? It will use existing paths to the DS8100. There are 8 devices on this new path. I've never done this sort of thing to a running system and have a certain respect for keeping it up and working. Experimenting is not an option for me. Thanks in advance for hints, tips, and an education. ____________________ James R.
