NMM 3.0 SP1 + Hyper-V 2012 R2 cluster backup

I have the same error, please help!

Networker Server: Windows Server 2012 R2, Networker 8.2

Hyper-V nodes: Windows Server 2012 R2, Networker client 8.2, NMM 8.2

Do you have a active-active cluster or a active passive cluster ?

Active-passive. The experimentally found the cause of the error: If the virtual machine is on a node that does not owner the quorum disk  - backup does not start. If the virtual machine and the owner of the quorum disk to the same node, the backup is started.

Active-Active.

So you have more than once virtual instance on your cluster ?

No, just one virtual instance (virtual cluster name).

Hi @Aleksander_Kucher

Have you checked the permissions and followed the steps in the documentation?

I can see OS permission denied error messages:

Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)))

Thank you,

Carlos

Hi Carlos Rojas  !

Our networker 8.2 archives Exchange 2013 cluster, administrator domain account are used in settings of service Replication Manager on the client. Security settings are no more.

For Hyper-V cluster in the documentation does not indicate anything. But even with the settings service RMAgentPS - the problem persists.
The solution was found in this forum: https://community.emc.com/message/803090. Checked at all works.

Can someone explain why this solution helped and how to be safe for archiving mood cluster Hyper-V?

Yes, the properties of the client-cluster in the Administration Console, I ordered the username and password with administrator privileges.

Please tell me where it is necessary to prescribe a list? Through command nsraddadmin server ...?

like this?
nsraddadmin -u *@hyper-v_node1

thanks

Hi Mandri,

What did you have set in the "Remote Access" field of the client configuration?

You should have at least the following information:

*@hyper-v_node1

*@hyper-v_node2

*@hyper-v_node3

*@hyper-v_node4

*@hyper-v_node5

*@hyper-v_virtual_node

Basically you need to add these lines into all Hyper-V nodes to allow each of them to access to each other.

Add as many physical and virtual Hyper-V nodes as present in your environment.

Thank you,

Carlos

Hi Carlos.

All permissions are correct, in the "Remote Access Field" all nodes and cluster name are set as you wrote:

*@hyper-v_node1

*@hyper-v_node2

*@hyper-v_node3

*@hyper-v_node4

*@hyper-v_node5

*@hyper-v_virtual_node

I'll try to set "Domain admin" account in the "Access" field and then i'll write a result.

Hello Carlos.

"Domain admin" account didn't resolve the issue. Maybe you know some other solutions?

I have seen many issues of that, most likely all result from inproper rights.

I described some common failures and the Solution to it here:

https://community.emc.com/blogs/bottk/2015/02/03/labbuildrnetworker-modules-for-microsoft-hyper-v-troubleshooting-with-l…

In my labbuildr toolkit i use this one to set rights for the Domain User on the local machines:

And this one to set the Networker Rights:

( note: all my Hyper-V Hosts start with HV, so i can filter an ad search guery to it.

If yiu can ot use the AD modules or run nsr on a non-windows box, you simply want to use nsraddadmin -u in 27 to 29 for each node
