error:client error: NFC Storage connection is unavailable. Failed To Create NFC Downstream
After installing Veeam at a clients site and setting it up to replicate a 2 host cluster and san to a single host with storage it tested OK in the test environment. The servers where then IP`d and put into the correct sub net with the relevant gateways etc.
Then the replication job was made live and left to run over night. Next morning I checked only to find this error below.
Now I knew that IP`s had been changed so I tested the following.
From the Veeam server.
Pinged its gateway – OK.
Pinged its DNS servers – OK.
Pinged the source VM hosts – FAIL
Pinged the storage – OK.
The the Veeam side failed on pinging the source hosts, I checked all my local settings which were ok. I went onto my hosts and checked the Local IP settings. It turns out that there was incorrect setting for the hosts gateway. I changed accordingly and the pings were fine.The hosts could not talk back to the Veeam server correctley. Then I set the replication away and it completed successfully.
The point of this post is the error:client error: NFC Storage connection is unavailable. Failed To Create NFC Downstream is generally an IP misconfiguration error or a communications error. So look there first and test the simple tings like pings.
That’s funny you posted this yesterday and I’m reading it now. Unfortunately I followed the steps and still cannot fix the issue. What’s more confusing is the backup was working 8 days ago and now IDK. I have added your tests to my info! TY
My issue was the DNS server used by VCenter Appliance, VM Host, Guest VMs, and everything else was not responding. Restarted service and error message went away
Thanks. This post helped me with the error. Seems I could ping everything except one of the hosts. Fixed that and it started backing up.
