DUMPCONDITIONING is a relatively new parameter compared with some, but it has been around for at least a decade. We've been using it for point-in-time DFDSS backups with FlashCopy since at least 2001. It enables you to keep the target volser unchanged so it can stay online. for the DUMP, yet if you do a RESTORE it will restore the volume with the original source volume volser. Causes some weirdness with the target copy volume, like you may not be able to OPEN individual SMS datasets or VSAM datasets on the copy volume because access methods seem to get upset if you attempt to point to one of these on a volume that conflicts with the cataloged volser - but DFDSS full volume dump has no problem.
Without the DUMPCONDITIONING we probably would have had to go with something like FDR. In retrospect, I'm glad we didn't, because the whole concept of having a utility able to process data from an "offline" volume seems like a bad idea. In many cases the whole point of having a volume offline is to guarantee a system is not using it so you can do things that would potentially cause data loss or unpredictable behavior if the volume were in use.
