Thanks Joe, this was exactly what I was looking for, however, I don't think this document is correct. This says Space optimized instant snapshots work with a standard licence and I think this is incorrect as the vxsnap manual says
If a valid FlashSnap(TM) license for FastResync is not present on the system, the prepare operation turns on dirty region logging (DRL) but not FastResync for a volume.
If FastResync is turned off, the addmir, dis (for leaf nodes only), make (for break-off snapshots only), print, reattach, rmmir, and split operations are permitted. The reattach operation requires a full resynchronization.
The refresh and restore operations, and the creation using make of full-sized or space-optimized instant snapshots are not permitted if FastResync is turned off.
Add this eeems to be the case, as I tested in 5.1 and when I prepared a volume, fastsync was not turned on and when I tried a vxsnap make a space optimized instant snapshots, I got an error saying "Volume does not have Fastresync enabled"
