<snip> According to my understanding, we need a CUADD for every controller on the FICON </snip>
I'm not sure what a "SL8500 ATL with STK 10000 drives" is but your comments seem to indicate that each CU is a tape drive? Is each STK 1000 drive a contol unit and do you have the same CHP going to all of the CUs? If in fact each tape drive is a separate CU and you have the same CHP going to the various CUs, then what you have should work. BUT your symptoms, ie only 600 comes online, seems to indicate that is not the case. Sounds like you have multiple drive off the same controller, not multiple controllers. I know with the IBM 3592, I had two controllers with six drive and had to CUADR the second controller. It would help if you could explain how many drive, CUs and CHPs are involved.
