Damned, I never thought to send such a msg "as is" !!! Outlook failed asking me to send a nice dump to microsoft.
I applied my (too often tested) Windows DRP to give you some feedback about this. First : I don't have any problem. We had years ago but no more now. Our procedure has been updated with this case. The fact is I just learnt the reason why a 3380 could have 3339 cyls. I was supposed to get this info from the support not through the forum :) Steve, you tell something very important here where DS8300 only accepts 3380TCM. Imagine we buy a DS8300. The day we will ipl our MVS in LPAR, I suppose the prod would be a bit surprized looking the vtoc and see what they thought to be a 3380-k. The impact could be dramatic, I suppose.
