I'm creating a number of flashcopy volumes on a V7000. These will be clones so will be detached once they are complete.
When the Flascopy Consistency Group is started are my target vdisk then available immediately for access by the host that will have the mappings to these target vdisks or do I need to wait until the cloning is completed it's entirety?
Section 5.3.2 Summary of FlashCopy indirection layer algorithm in the SVC and V7000 services red book kind of suggests I can use the target vdisks immediately. But if my is host writing to the target when the grain hasn't been copied from the source it says "Hold the write".
The source volumes currently have no other Flashcopy mappings. I will be creating these purely to create a single clone of each of the source vdisks.
