Two separate systems sharing a DS 8100. The z10 and z890 don't share an HCD. I cannot vary something online to the z890 that doesn't exist.

Re: Dynamically adding 3390's
No I'm sorry, I read but didn't comprehend that there were 2 separate Z systems. You can dynamically add everything from z/VM, however I've used HCD on z/OS so long now that I'm afraid I can't help with the proper CP commands to add the devices in z/VM.

How did you create the IOCP for the machine that has the VM partition in question? Go there and change the definition of those channels, control units and devices to include the VM partition.

Re: Dynamically adding 3390's
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.

Re: Dynamically adding 3390's
Over the years since dynamic IOCP changes became possible, I have had several occasions to use them. At first I ran into problems of not being able to activate the newly saved IOCDS (RC=88, I believe) because I had somehow or other gotten out of sync. So I created a special machine just for dynamic IOCP stuff, named, obviously, DYNIOCP. This machine presents a panel, which: - tells me if current status is DYN ON or DYN OFF - allows me to change the DYN status - records EVERY command entered, *AND* its resulting message(s) in a dated log file - allows me to scroll backward/forward through an unlimited number of previous commands - has a PF for FILELIST enabling me to look at log files, etc. So, I can be totally sure what changes I *did* do, and what I did *not*, and can create an IOCP source exactly matching the new hardware setup. I recently had to set up new dasd on the fly, after a long time with no new hardware, and using DYNIOCP made it a breeze! Seeing a successful result to SET IOCDS_ACTIVE is a real pleasure. Available on request, of course. (Pre-req: my XFS panel display program) Shimon
