Thank you, Rick. I did not CMS format the new 3390. I simply did a Flashcopy of the old volume cyls 1-10016 to the new 3390 1-10016. I have a system that I really need to upgrade, but there is not enough space on the old volume to do the upgrade. The last thing I want to have to do is install a new system and try to migrate the old system into it.
I will give this a try. On Thu, Aug 29, 2024 at 4:21 PM Rick Troth <[email protected]> wrote: > This is one reason why I keep saying we should do more with FBA and less > with CKD.
