NFC storage connection is unavailable.

Post by c0t0d0s0 » Oct 05, 2015 1:58 pm

We are demoing hardware from Nutanix and have run into a goofy problem. When we have a VM running on the Nutanix cluster we cannot back it up with Veeam. If we move it to a traditional server with traditional storage we can backup just fine. Same vCenter, same Veeam.

Error is:
10/4/2015 4:11:08 PM :: Processing mc1-txsw-ci Error: NFC storage connection is unavailable. Storage: [stg:datastore-590,nfchost:host-587,conn:mc1-vcenter60.<domain>]. Storage display name: [nutanix].
Failed to create NFC download stream. NFC path: [nfc://conn:mc1-vcenter60.<domain>,nfchost:host-587,stg:datastore-590@mc1-txsw-ci/mc1-txsw-ci.vmx].

Any thoughts?

Are you using vSphere 6 Update 1? If yes, see the sticky topic :D

I found the solution here (reactivate SSLv3 on port 902 on my ESXi hosts)

I followed the instruction posted here:

I have the same issue on vSphere 6 U1. This version disable SSLv3 which is used for SSL handshake during backup. VMware released update U1a, which enables SSLv3 and resovle this isuse.

[MERGED] Veeam Free

Post by alexia_net » Feb 24, 2016 9:34 am

Hi,
I am trying to take backup of a VM running on a vSphere 6 host. For backup i use Veeam Free. It's for testing purposes. I get an error
2/24/2016 9:54:42 AM :: Processing '<VM>' Error: Client error: NFC storage connection is unavailable. Storage: [stg:datastore-144,nfchost:host-143,conn:<IP>]. Storage display name: [datastore1 (1)].
Failed to create NFC download stream. NFC path: [nfc://conn:<IP>,nfchost:host-143,stg:datastore-144@<VM>/<VM>.vmx].
The storage is local.
The Veeam server, the VmWare host and the server I try to backup are on the same network segment.

Should the VSS feature be installed along with VmWare tools?

Any tips much appreciated.
Thank you!

Hi,
Thank you. It was one of those two:
- I had to upgrade the Veeam version
- the clock was not in sync between the Veeam server and VmWare host.

Thanks!
