During SureBackup, Instant Recovery, or Other-OS FLR operation, you receive the error:
"Error during the configuration of the host: NFS Error: Unable to Mount filesystem: Unable to connect to NFS server"
The NFS datastore cannot be mounted to the host, so vPower NFS based restores fail.
There are several possible causes for this:
In order to know which server to troubleshoot, one must know which server is acting as the vPower NFS server for the repository. To find this edit the repository for the backup files to be used in the restore. On the ‘vPower NFS’ tab there is a dropdown box designating which server is being used. The server listed is where the troubleshooting must be performed from.
*Note: An isolation step can be to try changing which server is chosen as the vPower NFS server in the Repository settings.
If the vPower NFS service is not running on the server designated within the repository settings, please review: http://www.veeam.com/kb1094

The following is a list of common troubleshooting steps
──────────────────────────────────────────────────────────
Test from vPower NFS server to VMkernel port:
1. Within a vSphere Client select the ESX(i) host that the NFS Datastore is being connected to.
2. Go to the Configuration Tab
3. Go to the Networking section
4. Look for a VMkernel port, and note its IP
5. Ping the VMkernel port from the vPower NFS server
Test from VMkernel port to vPower NFS server
1. Connect to the ESX(i) host that the NFS datstore is being connected to via SSH**
2. Using the vmkping command to test connectivity to the vPower NFS servers
Within a vSphere Client check the Configuration>Storage section of each host for datastores starting with “VeeamBackup_”, specifically ones that show up in italics with (Inactive). Unmount each of these and try the restore or mount procedure again.
1. Within a vSphere Client select the ESX(i) host that the NFS Datastore is being connected to.
2. Goto the Configuration Tab
3. Goto the Storage section
4. Click Add Storage…
5. Select the radio option for ‘Network File System’
6. For “Server”, enter either the IP or Hostname of the vPower NFS Server
7. For “Folder”, enter “/VeeamBackup_<servername>” servername is the NetBIOS name of the vPower NFS Server. If your vPower NFS server is added by IP, you need to specify VeeamBackup_XXX.XXX.XXX.XXX
8. Do not check the box for Mount NFS read only
9. Enter in to the Datastore name the same as folder without the starting forward slash. i.e. “VeeamBackup_<servername>”
10. Click next and complete the process.
