Unable to mount vPower NFS volume (<mountserver_ip>:/VeeamBackup_<mountserver>). Fault "AlreadyExistsFault",
Error The specified key, name, or identifier already exists.
Unable to create datastore VeeamBackup_<mountserver_ip> on host <esxi_host>, because it already exists
Before proceeding to more advanced troubleshooting steps, determine if a datastore matching the name specified in the error is visible via a vSphere Client. If so, unmount it.
If the unmount process fails, or there is no datastore matching the name visible, you should consider restarting the management agents on the ESXi host listed in the error.
If the issue persists after restarting Management Agents, review KB4167 for details on removing latent entries from the ESXi host's Datastore cache.
