The requested operation is not implemented by the server

[jpesick]

When ever I start a replication job I receive the following error twice right in a row in Vcenter.

"Create virtual disk: The requested operation is not implemented by the server."

My replication job is configured to use Direct SAN Access.
I don't get any errors in Veeam and the job seems to complete ok.
I don't get this error when I run a backup job.

Is this something I need to worry about?

No, this is fine. Veeam Backup will simply use another mode. This happens because vCenter Server does not currently implement certain VMware API commands that ESX(i) host has. If your replication target was ESX(i) host (added as standalone host to Veeam Backup), this API call would work fine.
