I have been searching the VMware knowledge base and I found this VMware KB: Consolidating snapshots in ESX/ESXi 3.x and 4.x that refers to this youtube video How to consolidate a snapshot in VMware ESX when there are virtual machine errors - YouTube
I have been told this command only clones and does not consolidate?
PS: The parentCID of the delta 0001 matches the CID of the original vmdk.
Cheers
