Hi listers, is there any significant functional difference on an ESS between the emulation of an LCU as 3990 Model 6 or 3990 Model 3. The reason of my question is the following.
My customer runs currently a multiprise 2003 with Ramac dasds andVM/ESA 2.2. We will upgrade his systemto zvm 5 and z890 with an ESS. Because there isn't left enough room in computer center to install the 2 additional boxes. We have firstly to install ESS and replace the old RAMACs with the old VM 2.2 and multiprise. Secondly we can install the z890 with zvm 5. I wonder if I can avoid installing the ESS ptfs for VM/ESA 2.2 (which I could still download fortunately) because it will only run a short period of time on ESS, when I define the LCU as 3990 Model 3. There is enough dasd space on ESS to copy the data under zvm 5 to 390 model 6 lcu afterwards and then redefine the 3990-3 lcus as model 6. Any advice would be welcome. Mit freundlichen Grüßen / best regards Franz Josef Pohlen
