I have found a cmd to consolidate the snapshots. I have checked the CID and parentCID of the base vmdk and the 0001-delta.vmdk and they are a match.
My question is, do I really need to poweroff the VM in order to do this command?
vmkfstools -i "Windows SBS 2008-000001.vmdk" /vmfs/volumes/4d395e37-36b73cfa-17f4-00199997b746/sbsTeste/WindowsSBS2008_new.vmdk
Cheers
