(This time with content.) In my experience, splitting and merging a sysplex are two very different activities. Merging is by far the more difficult because you likely have resolve name conflicts of all kinds, especially data set names. Are two like DSNs copies of the same data? If not, do you delete one? Integrate the content together? Rename (at least) one to keep them distinct forever?
Splitting hardly ever involves name conflicts because everything already lives together in the same environment. The biggest question in splitting PROD/DEV is whether you want everything to be accessible from both LPARs. If not, you have to build some barriers that presumable do not exist today. If you're aiming for two different sysplexes, sysplex boundary is a natural separator. If you're looking for two members of one sysplex, separating PROD and DEV will be more difficult. . .

Does anyone have a good checklist for this? The last time I did this was quite some time ago. I probably have most of the tasks identified, but can no longer find that old documentation I thought I had kept (too many laptop replacements). :( Looking for someone that may have kept theirs. In the meantime, reading "Setting Up a Sysplex" again for the nth time for memory clues :) Bob ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
