Physical adapters go missing after being applied to Logical Switch

August 13, 2014, 10:28 am

I have an existing VMM 2012 environment that has been working without trouble for quite some time. We're doing a domain migration, so I created a cluster on the new domain and added it to my old VMM environment to make the transfer of guests easier.

I an having trouble with creating Virtual Switches on the two new hosts in the new cluster. Essentially, I create a new logical switch using the configuration set up for the other existing servers and add two physical adapters to it. It's configured identically to my other two clusters. After I apply the changes, the switch is created and the NICs are teamed (verified in nic teaming console) but the physical adapters disappear both from the just-configured switch but also the hardware tab. Trying to connect a VM to this results in "not specified" being displayed in the connectivity field (browsing yields nothing).

I'm hoping I simply missed something since it's been ages since I had to build a new cluster but a side by side comparison seems to indicate the old/new clusters are configured similarly.

Thanks.

Remove one of cluster host from VMM console, but not remove cluster member

Hi Team,

I had an issue. I have 4 Hyper-V Cluster. and I have VMM 2012 to manage it.

suddenly my one of cluster node become bluescreen and I have to fresh install that server ( HV01 ). before it, I evict cluster node from Failover Cluster Manager console not from VMM. after the OS finish, I join the node with the same name and IP into my cluster via failover Cluster manager console.

When I Check SCVMM console, I see the HV01, become failed and show "need attention". In my Opinion, VMM cluster canot update the status of cluster. I try to install host agent from VMM into HV01, with "windows Server trusted domain" menu but error show like this.

after that I try to add host from menu "untrusted active directory domain". but it show all cluster member when I put FQDN of HV01.

Is there any issue at my cluster when I perform this step? because I have very important VM at my cluster :). If this step still get the same error, is there any other way?

please Help Team :)

Regards

Dear All,

            I have built a two-2 node SCVMM HA Failover Cluster:

Assume following

Node1 HOSTNAME        = SCVMM1      (First Management Server)

Node2 HOSTNAME        = SCVMM2      (Second Management Server)

WFC NAME                   = WFCVMM

SCVMM CLUSTER NAME = SCVMM

I have receiving following behavior from the nodes.

1.  On Node1, I can open console using SCVMM1, SCVMM and LOCALHOST, but cannot open console using WFCVMM?  Why is it so?

2.  On Node2 (When I make it active), I can open console using WFCVMM and SCVMM, but cannot open console using SCVMM2 and LOCALHOST?  Why is it so?

Am I missing something?

Highly Available Management Servers in SCVMM 2012

Dear All,

            I need to build Highly Available Management Servers (2) (SCVMM 2012) for my environment.  I am interested in following things:

1.  What are my options.  I have done little reading and seek confirmation that without building a windows failover cluster, one is not able to build HA SCVMM Management Servers?  Am I correct in understanding this?  If so, do I need a shared disk as well to create a cluster first and then install Management Servers? 

2.  What service accounts or groups are need during the configuration and what would be their permissions on respective servers such as Hyper-V Hosts and in Active Directory?

3.  Do we really need to create a container in Active Directory for an HA SCVMM scenario?

4.  Can HA solution be implemented without the WFC?

5.  Would appreciate, if you could share some of the links to blogs/articles about step by step instructions to it.

Thanks in advance.

Hi Team,

i have strange situation, i had cluster enviroment on my Hyper-V 4 node host. i also have same cluster at VMM 2012 SP1 console

someday, i had to move all my virtual machine from host3 to host2. at hyper-v, host 3 no VM running 

but, if I check the VMM console, host 3 still have VM running. if I check the properties of the VM, the VMM concosle become hung

is there any solution to solve this issue? without affecting the real cluster ( at Hyper-V ) :)

thanks before

Unsupported Cluster configuration.

Hi 

Im getting below error on refershing the host cluster I get below error . I have 2 hosts in the cluster and VMs report unsupported cluster configuration. SCVMM 2012 SP1 dont seem to see the Logical Switches . Although Upon restarting WMI Services on the host seem to fix the issue but after couple of weeks time I get the same error again. Upon doing some research I suspect when NIC Team moves the VNICs around and SCVMM agent doesnt get the latest information and therefore shows this error . 

Solutions I have applied so for and get no joy are below 

1. No snapshots are saved 

2. No ISO files are mounted 

3. VSS service set to manual 

4. Host switches have same name 

5. all VHD files are stored on CSV Volumes. 

6. Set one NIC in team as standby because MAC Address of the host management network  is same as physical address as I have inherited the settings while creating logical networks. 

Can Anyone please help

Not able to clone a VM with a shared hard drive

September 3, 2014, 9:43 am

I'm in the process of cloning some of my production servers into a test environment. I'm hung up on a SQL 2014 cluster of 2 servers. The Hosts are running Windows Server 2012 R2. The Guests are also Windows Server 2012 R2. The guests are using the new option to share a VHDX by going to the Settings of the virtual machine, then clicking Advanced features, then "Enable Virtual Hard Disk Sharing". I'm at a loss about how to get a copy of these two VMs into my test environment. I right click on either node from System Center Virtual Machine Manager 2012 R2 then choose Create --> Clone. However "Clone" is greyed out. I have also tried to export the VM from the Hyper-V management console but I get a failure with "General access error denied". I'm pretty sure that is because of the shared VHDX files. I have also tried the process with one of the nodes turned off with the same results. Turning both nodes off at the same time is not an option. Anyone have any ideas?

Hi,

I have a two node cluster on Windows server 2012 R2, am continuously getting the below alerts which results in the CSV to go to paused state and come back automatically online after 2 to 3 mins. I read few articles which says the apply of the fix KB2975719 will fix the problem but the fix is not available for download anywhere and also I didn't find any reason why the error occurs. Can someone please help to find out the issue and the fix?

Am using IBM storage and connected the LUN via fiber channel.

after host crash - cluster no longer working correctly in SCVMM 2012

Hi

one of our nodes in our cluster crashed. It came back. All the VMs on this host were running on other hosts so failover worked fine BUT for 2 VMs. One of those 2 VMs is - according to VMM - running on the crashed host. The other VM is - according to VMM - running on another host node which did not fail.

I have a lot of job errors saying that VMM library object virtuals disk is missing of those two VMs. So I looked into the FailoverManager. There I was able to see that the VMs are running on totaly different host nodes then what VMM tells me. In addition those VMs work just fine. I connected to both of them over Hpyer-V and they are just fine and the application also work without a problem. Please not those VMs are not shown twice or missing in VMM.

Live Migration to the Host node that crashed is no longer possible. But when looking into the status on VMM - it tells me that everything is fine. From Hpyer-V Manager I am able to do live migration to this host. But no longer from VMM console.

I rebooted the host node with no change. I refreshed the host nodes (all) in FailoverManager and in SCVMM, I refreshed the cluster... nothing. So I wanted to remove the cluster from SCVMM and re-add it. Doesn't work... It started with the first host and after that my cluster was somewhat broken (I thought that removing cluster - NOT "uncluster" - wouldn't have an effect on the cluster itself - well I was wrong). Anyway I repaired the cluster it is back into VMM but I still have the issues with the VMs. There are only warning on the VMM server that the library object (vhd) is missing but on the cluster nodes itself there are no errors.

Any ideas what I could do. I have no clue what to do about the VM which is supposed to be on this host but in FailoverManager it is on a totally different server. Any ideas?

SCVMM created VMs not displayed in Failover Cluster Manager

I have a 2012 Hyper-V failover cluster setup and recently added SCVMM 2012 SP1 to the mix so I could perform some P2V migrations and familiarize myself with its other many capabilities. I noticed that if I create a VM inside SCVMM it doesn't show up in the FCM UI with the other VMs I created from FCM. VMs that you create in FCM do get picked up by SCVMM however. Is this by design?

Thanks,

Greg

Newly created VMs will not migrate to other hosts in the cluster

I have a Windows Server 2012 R2 Hyper-V Cluster managed using SCVMM 2012R2.

I have several VM's that I have moved over from 2012 servers that work perfectly fine. I can migrate them from host to host without a problem.

I have 2 VMs that I created new within the new cluster. They will not migrate between hosts. The only difference I can see between the new and the old VMs is that the new VMs have a Self-Service Owner. This owner is an administrator role.

The error I am getting is below.

Error (12700)
VMM cannot complete the host operation on the HYPERV-09.lcunet.lcu.edu server because of the error: Virtual machine migration operation for 'LCURDS' failed at migration destination 'hyperv-03.lcunet.lcu.edu'. (Virtual machine ID 26739AD4-ECE9-42B6-910D-ABFD88B0A032)

Error Invalid Class in Cluster report when creating Hyper-V Cluster

Hi 

I've some trouble creating a Hyper-V Cluster in SCVMM 2012 SP1. I get the following error in the Cluster report:

List Information about servers running Hyper-V
Description: List Hyper-V related information on each specified node.
Gathering inventory data for servers running Hyper-V
Error message: An error occurred while executing the test. Invalid Class.

The setup is as follows:

- SCVMM Server running Windows Server 2012 R2 Datacenter with SCVMM 2012 SP1
- Two Hyper-V hosts running in VmWare Workstation that run Windows Server 2008 R2.
- SAN running Windows Server 2012 R2 Datacenter which is used as a ISCSI SAN for SCVMM and the two Hyper-V Hosts.
- SQL server running Windows server 2012 R2 and SQL Server running SQL Server 2012.

I'm running this version of VMM because i'm studying for the 70-247 exam.

When I run the Cluster wizard on one of the hyper-v hosts, I get no validation error.

Hope to get some hints and help to what might cause this error message.

Kind Regards

I'm deploying a Service Template based on Server 2008 R2 SP1.

The whole process (however time consuming) seems to go well, but in the end it fails with the following error:

Error (22658)
VMM guest agent encountered an internal error and cannot proceed.

Recommended Action
Check the guest agent state and then retry the operation.

I've checked the eventlog but there are no errors that point in this direction. Also the VMM Guest service is installed and running.
I also checked the logfile: C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager Guest Agent R2\bin\Diagnostics\VmmGuestLog.svclog

Microsoft.VirtualManager.GuestAgent.Common.GuestAgentException: Error in the application
