Hi John, some last thoughts mmdelnode/mmaddnode is an easy way to move non-NSD servers, but doing so for NSD servers requires to run mmchnsd, and that again requires a downtime for the file system the NSDs are part of (in Scale 4 at least, what we are talking right here). That could only be circumvented by mmdeldisk/mmadddisk the NSDs of the NSD server to be moved (with all the restriping). If that's ok for you go ahead.
Else I think you might give the mmchnode way a second thought. I'd stop GPFS on the server to be moved (although that should also be hot-swappable) which should prevent any havoc for Scale and offers you plenty of opportunity to check your final new network set-up, before starting Scale on that renewed node. YMMV, and you might try different methods on your test system of course.
