    Failed to copy one or more disks. Canceling Storage vMotion.
    Cannot copy source (/vmfs/volumes/SourceVolume/VM/VM.vmdk) to destination disk (/vmfs/volumes/DestinationVolume/VM/VM.vmdk): Device or resource busy

Cause

This issue occurs if the ESX host is unable to move the virtual disk of the virtual machine from the source datastore to the destination datastore during the Storage vMotion operation.

This is most likely due to intermittent SAN or network issues, such as unreachable storage or high storage latencies on involving the datastores related to the Storage vMotion operation.

Resolution

To resolve this issue, ensure that there are no problems related to the storage or network in your environment.
