Leo, please make sure you've followed the system requirements described in provider installation guide (p.11). Looks like configuration issue (provider cannot detect HBA card).

I have followed the installation guide, but I think the installation guide assumes that fibre channel is being used... We only use iSCSI, so there are no additional HBA's installed in our servers.

I changed something and now I have a different error message - feel like I am getting closer.
Created a new HyperV VM and on the first screen of the New VM Wizard under "store virtual machine in a different location" I pointed to a folder on the LUN that also holds my VHDs. So now my SAN volume also holds the XML, BIN and VSV files that constitute the VM configuration.

Now the error I get when trying to back up is
"Unable to create snapshot (Nimble Storage VSS Provider on This server) Details: Access is denied. RPC function call failed. Function name: [HvTestConnection]. Target machine: [10.10.10.10]. --tr:Failed to check whether HvIntegration service is available on '10.10.10.10:6163'."
Where 10.10.10.10 is the (obfuscated) IP address of my offhost proxy.

Note that I have made the LUN available to my offhost proxy server as well as the HyperV server - although in Disk Management on the offhost proxy, I have the disk Offline. And when I look at the backup proxy properties, under Connected Volumes, I do see the volume with the same drive letter as it appears to the HyperV server.

So now I think I need to troubleshoot the HvIntegrationService error message. My backup proxy server does have the HyperV role installed, but since it is a physical server and not a VM, I am unable to install the HyperV Integration Services on it.

Hi Guys
I have exact the same Issiue.

I have installed the rights Hardware Provider Dell Equalogic and my Eventlog is full with this:
Log Name: Application
Source: VSS
Date: 24.04.2012 14:08:40
Event ID: 8194
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: BFU103.bfu.ch
Description:
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.

Operation:
Gathering Writer Data


When I select Onhost Backup Veaam will make a clean Snapshot and the Backup works fine.

But Off Host will not working for me.

Hi Guys

I found for me the working Solution.

First you need a additional HyperV Proxy. So you have this Server and the new Proxy Server is on the first Position.

Then you need Manal Connectet Volumes. For me automatic not will working.

Then you need Diskpart Automount enabled.

At least Patch Nr. 3 must be installed.

We use a Dell Equalogic. So no Chap Account is defined.

For me it works now.

I hope it helps for some User.

Kind Regards

I got word from HP about my VSS problem. For VSS to work with an EVA P6300, you need it connected through Fibre Channel. As we are using iSCSI, the VSS hardware provider cannot find an HBA to mount the snapshot. Transitioning to FC won't be an option as it's not supported for a Hyper-V cluster.

I guess I have to let go the off-host proxy at least until we will be migrating to VMware early 2013...

Appreciate the update, Leo. You may want to check out what's coming in Windows Server 2012 in regards to Hyper-V enhancements though.

Hi,

I had also a problem that I forgot to install the Hardwrae Service provider on the Hyper-V Hosts. After installation of the right hardware provider the job still uses the same wrong driver.
In my case it was the MS Software provider.

Infrastructure - Managed Servers - MS Hyper-V - MS Hyper-V Cluster right mouse Rescan
solved the problem.

Andy,

My problem had nothing to do with using the wrong VSS driver. I could see the HP VSS provider is being used, however it expects my EVA P6300 being connected through FC and not through iSCSI, so it failed mounting the snapshot.

I am making on-host backups at the moment and that works fine for the moment. As soon as we will be migrating to VMware I will look at the off-host proxy again.

I am having the same issue. Compellent 4020 with Hyper-V 2012 R2. In manage volumes, I clearly see for each volume that I have the compellent hardware VSS provider as well as Microsoft's software VSS provider but when running the job, I keep getting this error:

5/12/2016 11:58:17 PM :: Unable to allocate processing resources. Error: There is no hardware provider for off-host backup detected. Snapshot failover is disabled.

I have notified VEEAM with support case ID: 01796653

Hi Rahid, if everything is configured according to the off-host backup requirements, then let's wait for what our engineers could say after reviewing the logs.

I am also having the issue with the error "Unable to allocate processing resources. Error: There is no hardware provider for off-host backup detected. Snapshot failover is disabled." when trying to setup an off-host proxy. I have an open ticket - 01865017.

from the link you just posted line 3 caught my attention:
"The source Hyper-V host and the off-host backup proxy must be connected (through a SAN configuration) to the shared storage".

It's either too late and I am just over thinking this, but what is considered the hyper-v host? The server that runs Veeam or the hyper-v host that makes up part of my cluster?

also can you help confirm the following
hyper-v server 2012r2 on a cluster
off-host running windows server 2012r2 (not hyper-v server).
^is this proper config for off-host or should my off-host also be running the hyper-v server version?

thanks!

It is your host, that runs VMs to be backed up. To explain it simple, off-host should have read access to the storage, where VM resides, to read it's snapshot, thus backing it up.
hyper-v server 2012r2 on a cluster
off-host running windows server 2012r2 (not hyper-v server).
^is this proper config for off-host or should my off-host also be running the hyper-v server version?

Off-host need to be
a) same windows version, as your production one (2012R2 and 2012R2, your setup is OK)
b) have hyper-v role enabled in any way. off-host need to "understand" what is VM, VM config, disk, etc, to read it correctly. looks like this can be the cause of your problem
also, there is
c) have same hardware provider, as your hosts in cluster, to successfully read data directly from shared storage.

Thanks for clarifying the host question, I thought it was the host running the vm's but wanted to double check.

Off-host need to be
a) same windows version, as your production one (2012R2 and 2012R2, your setup is OK)
b) have hyper-v role enabled in any way. off-host need to "understand" what is VM, VM config, disk, etc, to read it correctly. looks like this can be the cause of your problem
also, there isa
c) have same hardware provider, as your hosts in cluster, to successfully read data directly from shared storage.


a
nodes= hyper-v server 2012r2
off-host= window server 2012r2
my veeam server - running on a physical server with Windows Server 2012 (non-R2) <-does this matter?

b
off-host does have the hyper-v role enabled.

c
hardware provider? as in the storage? the vm's reside in a powervault and the backups are going to a qnap. both hosts and off-host have the powervault mpio drivers. I dont have any qnap drivers. is the qnap the issue? I doubt it since the snapshot needs to be done at the powervault not the qnap, correct? this is how my setup works without the off-host in the picture; the snapshots are done on the PV and the backups saved to the qnap which does no snapshots.

thanks!
