2012R2 Hyper-V Cluster

We have a 2012R2 Hyper-V cluster with 7 nodes. I created 7 clients (hv-c8n2.domain, etc) for each node and 1 client for virtual cluster name(cl08.domain.com). Each node has NW and NMM. When i start group with virtual cluster name it backs up only VMs  hosted on current cluster owner node and ends successfully. The VMs on the other nodes do not backup at all or even attempt to backup.When I move core cluster resources to a different node it will backup only VMs which hosted on that node. I tried many suggestions I found here and still backs up only VMs on the cluster owner.

I am not sure if the problem is this but.....

I get one of these for each node except the cluster owner.....The error in the nmm.raw is :

NSR info NMM disabling the Automount feature failed with Error HV-C8N2.domain : Access is denied.

I have tried adding a domain_name\domain_admin info to the Access: Remote User field on the client for virtual cluster name. I get:

*cl08.domain.com:savefs Cannot run savefs: The requested operation requires elevation. (Win32 error 0x2e4)

* cl08.domain.com:APPLICATIONS:\Microsoft Hyper-V Cannot run savefs: The requested operation requires elevation. (Win32 error 0x2e4)

Any help with this matter is greatly appreciated. Thank you

This is a Windows UAC Problem.

You need to exactly follow the Guide for NMM Hyper-V VSS

Under Access in the Client Properties, have  a remote user  that is admin on the Local Nodes and Cluster Admin !

Make sure tha UAC is disabled ! ( requires Reboot)

Thanks so much for the help.

I was using a domain admin account and figured that would get me past the UAC but indeed it does not.

I disabled UAC on all nodes (and rebooted) and tried again with the same domain admin account and all is working well now.


Thank you

Hi,

we also have this error and we have disabling the UAC, but the error still the same:

Cannot run savefs: The requested operation requires elevation. (Win32 error 0x2e4)


Networker version 8.1.2.5, Windows 20012 R2

Hyper-V cluster with 4 Nodes (NMM and Networker installed everywhere), windows 2012 R2

Any Idea about this?

Thanks a lot

I disable UAC on each node and you reboot each node after change. May want to drain roles and move disks.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\

"EnableLUA"=dword:00000000


Then make sure you place the domain_name\admin and its password in the remote user on the HVCLUSTER client properties.

Hope this helps

Hi,

by settings this 2 parameter in the local security policy mmc of the node:

-    User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode: Elevate without      prompting.

-    User Account Control. Run all administrators in Admin Approval Mode: Disabled

It's has solve the issue.

Thanks for the help

Cheers
