Hello,

does the VM you are trying to migrate have any snapshots? Does your array support VAAI and is it active on your datastores?

Stop by my blog if you'd like 🙂 I dabble in vSphere troubleshooting, PowerCLI scripting and NetApp storage - and I share my journeys at http://vmxp.wordpress.com/

Do you have vmware flash read caching enabled? If so, try turning it off on the VM and see if it goes through with svmotion.

Regards,

Jocke

Okey, if you just do a vMotion, will it succeed?
