Failover Cluster Manager - Partioned Networks Server 2012
Hello,
I have a DR cluster that I am trying to validate. It has 3 nodes. Each has a teamed vEthernet adapter for Cluster Communications and Live Migration. I can start cluster service on 2 of the 3 nodes without the networks entering a partioned state. However,
I can only ping the I
Ps for those adapters from their own server . Also, It doesn't matter which 2 nodes are brought up. Any order will produce the same results. Validation gives the following error for connections between all nodes:
Network interfaces DRHost3.m1ad.xxxxxx.biz - vEthernet
(vNIC-LiveMig) and DRHost2.m1ad.xxxxxx.biz - vEthernet (vNIC-LiveMig) are on
the same cluster network, yet address 192.168.xxx.xx is not reachable from
192.168.xxx.xx using UDP on port 3343.
Update: I have created a specific inbound rule on the server firewalls for port 3343. The networks no longer show as partitioned. However, I still receive the same errors about communication on port 3343 to and from all nodes on the LiveMig and ClustPriv
networks. Any help would be appreciated.

Change "Services and applications" names in failover cluster manager
Hi. Id like to change "Services and applications" names in failover cluster manager for Windows Server 2008 R2.
I right click on one and press rename, but when i change the name and press enter i get the message "To rename this service or application please rename the Client Access Point via its property page"
It's important that we don't change the network name for the serviceHi,
Checkout this blog post
PowerShell for Failover Clustering: Let’s Rename a Few Things
But keep in mind if you rename the resources and you are using them in a script or backup you need to check this also with the new name.

I have a 4 node Server 2012 R2 Hyper-V Cluster and manage it with VMM 2012 R2. I just upgraded the cluster from 2012 RTM to 2012 R2 last week which meant pulling 2 nodes out of the existing cluster, creating the new R2 cluster, running the copy
cluster roles wizard since the VHDs are stored on CSVs, and then added the other 2 nodes after installing R2 on them, back into the cluster. After upgrading the cluster I am unable to migrate some VMs from one node to another. When trying to do
a live migration, I get the following notifications under the Rating Explanation tab:
Warning: There currently are not network adapters with network optimization available on host Node7.
Error: Configuration issues related to the virtual machine VM1 prevent deployment and must be resolved before deployment can continue.
I get this error for 3 out of the 4 nodes in the cluster. I do not get this error for Node10 and I can live migrate to that node in VMM. It has a green check for Network optimization. The others do not. These errors only affect
VMM. In the Failover Cluster Manager, I can live migrate any VM to any node in the cluster without any issues. In the old 2012 RTM cluster I used to get the warning but I could still migrate the VMs anywhere I wanted to. I've checked the network
adapter settings in VMM on VM1 and they are the same as VM2 which can migrate to any host in VMM. I then checked the network adapter settings of the VMs from the Failover Cluster Manager and VM1 under Hardware Acceleration has "Enable virtual machine
queue" and Enable IPsec task offloading" checked. I unchecked those 2 boxes refreshed the VMs, refreshed the cluster, rebooted the VM and refreshed again but I still could not live migrate VM1. Why is this an issue now but it wasn't before
running on the new cluster? How do I resolve the issue? VMM is useless if I can't migrate all my VMs with it.I checked the settings on the physical nics on each node and here is what I found:
Node7: Virtual machine queue is not listed (Cannot live migrate problem VM's to this node in VMM)
Node8: Virtual machine queue is not listed (Cannot live migrate problem VM's to this node in VMM)
Node9: Virtual machine queue is listed and enabled (Cannot live migrate problem VM's to this node in VMM)Node10: Virtual machine queue is listed and enabled (Live Migration works on all VMs in VMM)
From Hyper-V or the Failover Cluster manager I can see in the network adapter settings of the VMs under Hardware Acceleration that these two settings are checked "Enable virtual machine queue" and Enable IPsec task offloading". I unchecked those
2 boxes, refreshed the VMs, refreshed the cluster, rebooted the VM and refreshed again but I still cannot live migrate the problem VMs.
It seems to me that if I could adjust those VM settings from VMM that it might fix the problem. Why isn't that an option to do so in VMM?
Do I have to rebuild the VMM server with a new DB and then before adding the Hyper-V cluster uncheck those two settings on the VM's from Hyper-V manager? That would be a lot of unnecessary work but I don't know what else to do at this point. -
Failover Cluster Manager 2012 Showing Wrong Disk Resource - Fix by Powershell
On Server 2012 Failover Cluster Manager, we have one Hyper-V virtual machine that is showing the wrong storage resource. That is, it is showing a CSV that is in no way associated with the VM. The VM has only one .vhd, which exists on Volume 16.
The snapshot file location and smart paging file are also on Volume 16. This much is confirmed by using the Failover Cluster Manager to look at the VM settings. If you start into the "Move Virtual Machine Storage" dialog, you can see
the .vhd, snapshots, second level paging, and current configuration all exist on Volume 16. Sounds good.
However, if you look at the resources tab for the virtual machine, Volume 16 is not listed under storage. Instead, it says Volume 17, which is a disk associated with a different virtual machine. That virtual machine also (correctly) shows Volume
17 as a resource.
So, if everything is on Volume 16, why does the Failover Cluster Manager show Volume 17, and not 16, as the Storage Resource? Perhaps this was caused by an earlier move with the wrong tool (Hyper-V manager), but I don't remember doing this.
In Server 2003, there was a "refresh virtual machine configuration" option to fix this, but it doesn't appear in Failover Cluster Manager in Server 2012.
Instead, the only way I've found to fix the problem is in PowerShell.
Update-ClusterVirtualMachineConfiguration "put configuration name here in quotes"
You would think that this would be an important enough operation to include GUI support for it, possibly in the "More Actions" right-click action on the configuration file.Hi,

Network DR test causes Exchange DAG network to fail (Failover Cluster Manager reports comms errors)
We have a DAG configured between 2 mailbox servers, one in each of our main data centres. Our comms team recently performed a DR test between our 2 data centres, switiching from the main production link to the backup link. During this outage the Failover
Cluster Manager reported errors, with each mailbox server reporting the other as uncontactable. The Events that were logged include the following:
Isatap interface isatap.{02ADE20A-D5D4-437F-AD00-E6601F7E7A9D} is no longer active. (EventID 4201)
Cluster node 'MAILBOX_SERVER' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the
Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is
connected such as hubs, switches, or bridges. (EventID 1135)
File share witness resource 'File Share Witness (\\WITNESS_SERVER\SHARE_NAME)' failed to arbitrate for the file share '\\WITNESS_SERVER\SHARE_NAME'. Please ensure that file share '\\WITNESS_SERVER\SHARE_NAME' exists and is accessible by the cluster. (EventID
1564)
Cluster resource 'File Share Witness (\\\WITNESS_SERVER\SHARE_NAME)' in clustered service or application 'Cluster Group' failed. (EventID 1069)
The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk. Run the Validate a Configuration wizard to check your network
configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges. (EventID 1177)
The Cluster Service service terminated with service-specific error A quorum of cluster nodes was not present to form a cluster. (EventID 7024)
The Microsoft Exchange Information Store service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 5000 milliseconds: Restart the service. (EventID 7031)
Looking at the Cluster Events in the Failover Cluster Manager Snap-In i see a heap of Event ID 47 (cannot activate the DAG databases as the server is not up according to Windows Failover Cluster Service) and:
Node status could not be recorded. This could prevent some network failure logic from functioning correctly. NodeStatus:IsHealthy=True,HasADAccess=True,ClusterErrorOverrideFalse,LastUpdate=5/2/2011 8:25:42 AMUTC Failure:An Active Manager operation failed.
Error: An error occurred while attempting a cluster operation. Error: Cluster API '"ClusterRegSetValue() failed with 0x6be. Error: The remote procedure call failed"' failed.. (EventID 184)
Forcefully dismounting all the locally mounted databases on server 'BACKUP_MAILBOX_SERVER. (EventID 307).
Our Comms team doesn't believe it is a comms issue as they did not log any network communication errors between the servers in the two sites (using icmp). So if it is not a comms issue, how can I configure the Failover Cluster Manager to be resilient to
this type of network failover event.
Thanks
DanIsn't it also true that in a stretched DAG with even numbered nodes, the PAM needs to be in the same site as the active DAG node? If the connection between both nodes goes down, and the PAM is in the "passive" site, the primary node will
dismount the databases since it can't check with the PAM to make sure its safe for it to be up.
In a even-numbered node stretched DAG, the PAM changes to the DR/passive site everytime a failover occurs, but doesn't automatically switch back when you reactivate the primary node. -
I can't find failover cluster management after creating hyper-v cluster on SCVMM 2012 R2
I've created a hyper-v cluster on scvmm 2012 r2 but I can't find the failover cluster manager to move storage resources. all hosts are showing to have hyperv role and failover clustering feature installed. disk Witness in Quorum is good, same as for the
other CSV lun. Please help me Microsoft. Thank you.The management consoles are not getting installed while building the cluster through SCVMM. However, its not mandatory to have the management tools on the server. You can have it on a different machine with this management tools installed and connect to
this cluster remotely.
Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence.

I have created cluster using powershell cmdlets on Hyper-V server because I was unable to create a cluster using RSAT-Failover Clustering (May be some privileges issues).
The problem is " I am still not able to create a Hyper-VM using Failover Cluster Manager on WS2012 DC Edition server". It gives me an error "Invalid operation"
Any Help regarding this issue will be very appreciated.
Thanks in Advance.....
Abhinav | MCTS-Server VirtualizationThanks Tim for your response but atleast I should be able to create and configure VMs for high availability.
I think this is not the issue which I am facing. It gives me an error "invalid class". There is something missing.
Please check and let me know if it can be solved. Any help will be really appreciated.
Thanks in advance.

Hyper-V internal (1 of 2, NOT Cluster) network unavailable in Failover Cluster Manager 2008R2
Hi all,
I had a very strange situation in my Hyper-V 2 nodes-cluster:
I have one networtk for HertBeat only (10.0.0.0/24) and second for HyperV internal networking for virtual machines (In properties marked "Do not allow clustern network communication")
Machines were working properly and any migration too.
One day, my secon done HyperV2 was marked red in Failover Cluster Manager mmc. I discovered that HyperV LAN is unavailable on this second node. BUT everything war working properly - HyperV2 node was on internet, communicated to AD domain, even culd run any
virtual machine...
Several times I checked the configuration, also check TMG configuratio, I was wondering if it can not be wrong settings on network access rule, I tried to restart this host - no result, ... network was still unavailable.
After about a hour I found the resolutuion:
On my second Hyper-V node Disable / Enable Local Area Connection network adapter, connected to Hyper-V LAN in Network Connections control panel!
Hope this will help to somebody ;)
Marian, just trying to help youResolutuion:
On affected Hyper-V node Disable / Enable Local Area Connection network adapter, connected to Hyper-V LAN in Network Connections control panel
I guess, sometnig flush on network configuration and / or some combination with network adapter driver

How to enable "persistent mode" in Windows failover cluster manager 2012?
In Windows Server 2008 R2 there was a checkbox named "Enable persistent mode" on a General tab in the Properties of a cluster resource.
In Windows Server 2012 that seems to have disappeared.
My cluster resource is a "generic script" resource (not that it makes any difference).
How do I enable "persistent mode" for a cluster resource in Windows Server 2012?
ThanksHi Marcus Griley,
Enabled by default for VM groups Option is hidden from GUI in 2012, you can use the specify the preferred owner of group to realize the same function, positively not come online
on a node that is not a possible owner. If no possible owner nodes are up, then the group will still failover to a node that’s not a possible owner, but it will not come online.
Preferred Owners in a Cluster
http://blogs.msdn.com/b/clustering/archive/2008/10/14/9000092.aspx
Specify preferred owners of a group:
https://technet.microsoft.com/en-us/library/cc759663(v=ws.10).aspx
Set group FailOver policy:
https://technet.microsoft.com/en-us/library/cc786993(v=ws.10).aspx
Set group FailBack policy:
https://technet.microsoft.com/en-us/library/cc778570(v=ws.10).aspx- This will help the resources to fail back on the preferred owner.
I’m glad to be of help to you!

Cluster Network 2 is missing from Failover cluster Manager
I have two node Windows 2008 R2 SP1 MS SQL cluster, there was an issue with one node NIC card which was replaced and since then "Cluster Network 2" is not visible in failover cluster manager, also Heartbeat and Public IP nic card of both nodes
are appearing in "Cluster Network 1" container. even though both network public and hearbeat are on differenet subnet, but still cluster detects it as one subnet. Need to know how to bring back "Cluster Network 2"After replacing NIC, cluster worked fine on other node for couple of days and then cluster services started terminating on both the nodes.
when checked cluster logs found below error.
"ERR [CORE] Node 2: exception caught AlreadyExists(183)' because of 'already exists'(AODBP2DB1 - Local Area Connection)"
Hence to correct this problem, renamed both nodes NIC cards as Public and Private and cluster was started and tested the failover also. but since then only able to see "Cluster Network 1" and all NIC are listed under this container.
Though when looked at cluster validation report, it shows Cluster Network 1 and Cluster Network 2 entries in it

VM will not boot after moving using Failover Cluster Manager - "a disk read error occurred......"
My current Configuration:
3 node cluster, using clustered shared storage and about 22 VM's. The Host servers are running 2012 Data Center while all guest are running 2012 Standard. The SAN is EqualLogic and we are using HIT Kit 4.5.
I have a CSV that is running out of space, so I created another CSV so that I could move some of the VM's to a new home. I tested this by creating a test VM, and moved it successfully 3 times. I then moved an actual
LIVE VM and while it seemed to move ok, it will now not start. The message is "a disk read error occurred Press ctrl+alt+del to restart". I moved the test VM and it failed as well.
I have read several things about this, but nothing seems to relate to my specific issue. I have verified that VSS is working and free of errors as well. From the Settings menu for the VM, if I select "Inspect" the drive,
the properties all look fine. It is a VHDX and both the current file size and maximum disk size seem correct.
The VM's were moved using the "move - virtual machine storage" option within Failover Cluster Manager.
Suggestions?
Thanks.Lets see if I can answer all of those and I appreciate the brain storming. This really needs to work, correctly.
1. The Storage is moving.
2. VM's and SAN are on same device.
3. No, my Clustered Shared Volume, CSV, is out of room, (more one that later)
4. No, I actually have 2 sans grouped together. However, I'm moving the VM', form one CSV to another CSV on the Same san. EqualLogic PS 6110 is the one I am trying to move VMS around on, and the other SAN not involved in any way except
for it is in a SAN group is an EqualLogic PS6010.
5. No error During move, it took about 5-10 minutes, no error messages. Note, I did a test and it worked GREAT 3 times. Now both a live VM, and the test VM are doing the same thing.
6. No, the machine is not to large. The test making was a 50 gig drive, just 2012 standard installed with updates. The live VM was a 75 gig VM that was my Trend Micro Server, or anti-virus host.
7. Expand the existing SCV? Yes I should be able to, but there is an issue there. The volume was expanded correctly, Equallogic sees the added space, Fail Over cluster manager sees the added space, however disk manager only
sort of does. When looking at disk manager, there are 2 areas that tell you a little bit about the drive. The top part and then the bottom part. The top part only shows 500G, the original size, while the bottom part
says that it is 1 TB in size. I call Dell's technical support and after they looked at it I was told by the technician that they had seen this a couple of times and the only way to fix it was to move all the VM's to another CSV and delete the troubled
CSV. I thought about adding more space to the troubled CSV, but its on a production server with about 12 VM's running on it and I did not want to take a chance. The Trend VM was running on CSV-1 and working fine.
I must admit that the test VM, was on CSV-2. I moved the Test VM from csv-2 to csv-3 back and forth several times with no errors. The Trend Server was on CSV-1 and was moved to CSV-3, however it failed. Again, I then moved
the test VM from CSV-2 to CSV-3 and it failed the same way. I could not test the "TEST - VM" on csv-1 due to csv-1 not having enough space.
8. I did disable the network from the VM to see if that mattered it did not.
9. I have not yet had a chance to connect the VHDX to a new VM, but I will do that in about an hour, hopefully. Once I am able to test that suggestion I will post the results as well.
Again, thanks for all the suggestions and comments, as I had rather have lots to look at and try. I hope I answered them well enough.

How to recover from accidental VM role removal in Hyper-V Failover Cluster Manager?
Hello
My VMs are still available in Hyper-V Manager but they are no longer available in Cluster Manager. I am curious if there's a way to move them back into the Failover Cluster Manager while retaining their GUIDs?
I know I can manually create a new VM and add the existing VHD but that process recreates a new GUID causing the VM to regard the stuff I wanted as old.
I have tried to follow
http://blogs.technet.com/b/heyscriptingguy/archive/2013/10/14/recovering-virtual-machines-in-hyper-v-server-2012-r2-part-1.aspx but I am curious if there's a faster way to do this without becoming a scripting genius overnight.
Thanks,
PrinceThanks for the reply but that does not help.
I am not looking to move my VMs to a remote Host but rather looking to repopulate the fail-over cluster manager with the existing VMs in Hyper-V Manager. In a sense, I am looking to reuse the existing GUID without creating new ones.
Again, my VMs are alive in Hyper-V Manager but are currently not available in Failover Cluster Manager.
Any scripting assistance will be greatly appreciated.
Thanks,

Hello :)
I have to ask because this issue is boring me a long time ago :(
From time to time when I connect to virtual machine from failover cluster manager console I've get virtual machine connection screen (console) which is reduced only to upper left quorter of full screen. There is no scroll bar ... If I live migrate
VM to another node (or restart VM on same node) and reconnect, console screen is displayed ok (ie all console screen is visible).
It is happening regardless of OS version installed into guest VM: 2003 R2, 2008 R2, 2012, 2012 R2).
I've check inside VM ( I can see that integration services are installed and running but when I click onto console window with mouse I've get message:
"Virtual Machine Connection
Mouse not captured in Remote Desktop session
The mouse is available in a Remote Desktop session when
integration services are installed in the guest operating
system...."
From SCVMM console I can see that IC version on guest VM is: 6.1.7601.17514
I would like to know what is going on and is there any way how can I detect those situation or even better how to prevent it ?
Thank you for any idea.
Best regards
NenadHi Nenad,
As you mentioned you have tried 2003 R2, 2008 R2, 2012, 2012 R2 guest vm, but all this do not work properly, With Server 2003 platform the 2008r2 Hyper-V the 2003R2 are not
supported, in your case you must update to Windows Server 2003 R2 with Service Pack 2.
Server 2012 as guest vm on 2008r2 you must install the following hot fix:
You cannot run a Windows 8-based or Windows Server 2012-based virtual machine in Windows Server 2008 R2
https://support2.microsoft.com/kb/2744129?wa=wsignin1.0
Server 2012 is the last version of Windows that will be supported as a guest operating system on 2008r2 Hyper-V therefore the 2012r2 guest vm is not supported.
Please use the following command can query all guest vm’s IC version, please compare this problematic vms IC version with functioning vms.
The following powershell command can be used to display the version of integration services installed on all VMs on the Hyper-V host:
PS C:\Users\administrator> get-vm | ft name, IntegrationServicesVersion
Name
IntegrationServicesVersion
TestVM2012
6.2.9200.16433
SQL01
6.2.9200.16433
SQL02
6.2.9200.16433
SCVMM01
6.2.9200.16384
SCVMM02
6.2.9200.16384
I’m glad to be of help to you!

Monitor Replication Health in Failover Cluster Manager?
Have two Hyper-V 2012 R2 Clusters.
One Cluster contains all production VM's.The second cluster is on another location and is intended only for HA purposes. All production VM's from the first clusters should be replicated to the other cluster.
What is the best way to monitor the replication health of all VM's? In Failover Cluster manager, it's not possible to add a column "replication health" to the "roles" window. It's not practical to click on every VM to view the replication
health. In Hyper-V Manager, it's easy to add "replication health" to the virtual machine window, but clicking on every host to verify the replication health is not very practical as well.
Thank you in advance for any hint (I know that we could use SCOM or something similar, but these complex tools are out of scope).
FranzHi FranzSchenk
I think the only real option open to you is the use of PowerShell in your situation. Have a look at this link and see if this is the sort of thing that will help you.

Failover Cluster Manager Missing
I created new Windows 2012 R2 Servers (non-core) and configured a functional failover cluster.
I then removed the GUI using the Powershell command:
Remove-WindowsFeature Server-Gui-Shell, Server-Gui-Mgmt-Infra
After testing applications, it was determined that the applications would not run properly without the server GUI shell. I added it back using the following PowerShell command:
Add-WindowsFeature Server-Gui-Shell, Server-Gui-Mgmt-Infra
I notice that after this, when I go into Server Manager, Failover Cluster Manager is no longer available.
How do I restore it?Hi;
Simply remove the Failover Cluster Management Tools from the Remote Server Administration Tools in Server Manager and reinstalling it again should resolve your problem.
