Hyper-V R2 Cluster and CSV

Hi, I'm pretty new in the hyper-v world.
And I'm planning to migrate more servers to an hyper-v failover cluster with Fibre Channel SAN. I'm wondering about the CSV and the possibility to have less LUN with that. There is a lot of ressources about CSV since Windows Server 2008 R2, and all are speaking
about the advantages!
But I'm asking if there is some requirement other than those described here: http://technet.microsoft.com/fr-fr/library/jj612868.aspx#BKMK_Reqs
1/ If I use only a dedicated 1Gbs network interface for CSV, will I slowdown the VMachines?
2/ Is the Hyper-v physical HardDrive heavily used?
3/ If a node loses the storage connectivity is it possible (with no human intervention) to switch the concerned VMachines to an other node to avoid the I/O Redirection?
.... Or other things to take care?
Regards,
L.H.

1. Do you mean connections to storage or connections between nodes for CSV? If it's to storage, then any amount of network speed you can use up to the highest speed of the storage is "the best". I find that most people dramatically overestimate how fast
their storage really is. 2-4 Gbps is typically a sufficient pipe for most needs. If you mean between nodes, then 1Gbps is usually sufficient.
2. No. Its major events will be boot up, patching, and shut down. During normal operations, the drive space that holds Hyper-V and the management operating system will be almost completely idle.
3. Sort of. The built-in tools won't do it, because not needing to move the VMs is one of the reasons that Redirected Access exists. But, you could script a Live Migration to respond to a storage outage.
Or other things to take care?
There are always other considerations, but that question is a little too wide.

Hyper-V Failover Cluster Configuration Confirmation

Dear All,
I have created a Hyper-V Failover Cluster and I want you to confirm if the configuration I have done is okay and I have not missed
out anything that is mandatory for a Hyper-V Failover Cluster to work. My configuration is below:
1. Presented Disks to servers, formatted and taken offline
2. Installed necessary features, such as failover clustering
3. Configured NIC Teaming
4. Created cluster, not adding storage at the time of creation
- Added disks to the cluster
- Added disks as CSV
- Renamed disks to represent respective CSV volumes
- Assigning each node a CSV volume
- Configured quorum automatically which configured the disk witness
- There were two networks so renamed them to Management and Cluster Communication
- Exposed Management Network to Cluster and Clients
- Exposed Cluster Communication Network to Cluster only
5. Installed Hyper-V
- Changed Virtual Disks, Configuration and Snapshots Location
- Assigned one CSV volume to each node
- Configured External switch with allow management option checked
1. For minimum configuration, is this enough?
2. If I create a virtual machine and make it highly available from hyper-v console, would it be highly available and would live
migrate, etc.?
3. Are there any configuration changes required?
4. Please, suggest how it can be made better?
Thanks in advan

Hi ,
Please refer to following steps to build a hyper-v failover cluster :
Step 1: Connect both physical computers to the networks and storage
Step 2: Install Hyper-V and Failover Clustering on both physical computers
Step 3: Create a virtual switch
Step 4: Validate the cluster configuration
Step 5: Create the cluster
Step 6: Add a disk as CSV to store virtual machine data
Step 7: Create a highly available virtual machine
Step 8: Install the guest operating system on the virtual machine
Step 9: Test a planned failover
Step 10: Test an unplanned failover
Step 11: Modify the settings of a virtual machine
Step 12: Remove a virtual machine from a cluster

Hyper-V Failover Cluster Networking Configuration After Install

Hello All,
Is it possible to install hyper-v and failover or in other words create a hyper-v failover cluster and then configure the networking part of the solution later? As I am coming into
terms with the networking part of it, wanted to do it later after the install. Is it possible?
And from later configuration, I am trying to say, creation of NIC Team, Virtual NICs, VLAN tagging, etc.

Hi,
Failover cluster deployment requires network connectivity between cluster nodes. You can't create a cluster without properly configured TCP\IP on cluster nodes.

Access is denied messages in Win2012 R2 Failover Cluster validation report and CSV entering a paused state

Been having some issues with nodes basically dropping out of clusters config.

Access is denied
The event viewer on one of the hosts shows
Cluster node 'zhyperv2' lost communication with cluster node 'zhyperv1'. Network communication was reestablished. This could be due to communication temporarily being blocked by a firewall or connection security policy update. If the problem persists
and network communication are not reestablished, the cluster service on one or more nodes will stop. If that happens, run the Validate a Configuration wizard to check your network configuration. Additionally, check for hardware or software errors related
to the network adapters on this node, and check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
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.
Only other warning is because the 4 nic ports in each node server are teamed on one ip address split over two switches - I am not concernd about this and could if required split then pairs, I think this is a red herring????

Hi,
Such events happen because of the following reason:
1- Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks not enabled on all network interfaces. Check this KB article: http://support.microsoft.com/kb/2008795
. Please make sure these two protocols are enabled on all cluster networks
2- Network connectivity issue can cause this event as well. Please make sure the network cabling/Cards/Switches are correctly configured and working as expected
3- Connectivity issue with the storage can also cause this event. Please make sure all the nodes are connected to storage. Check HBA/Cabling connectivity to SAN. Make sure
that the SAN drivers are up-to-date.
4- Antivirus may interrupt network communication and cause this failure. Please exclude CSV volumes from being scanned by AV: http://social.technet.microsoft.com/wiki/contents/articles/953.microsoft-anti-virus-exclusion-list.aspx

2 Hyper-V Servers with Failover Cluster and a single File Server and .VHDs stored on a SMB 3 Share

I have 2 X M600 Dell Blades (100 GB local storage and 2 NICs) and a Single R720 File Server (2.5 TB local SAS storage and 6 NICs). I´m planning a Lab/developer enrironment using 2 Hyper-V Servers with Failover Cluster and a single File Server putting
all .VHDs stored on a SMB 3 Share on the File Server.
The ideia is to have a HA solution, live migration, etc, storing the .VHDs onm a SMB 3 share
\\fileserver\shareforVHDs
It is possible? How Cluster will understand the
\\fileserver\shareforVHDs as a cluster disk and offer HA on it?
Or i´ll have to "re-think" and forget about VHDs on SMb 3 Share and deploy using iSCSI?
Storage Spaces makes difference in this case?

You can do what you want to do just fine. Hyper-V / Windows Server 2012 R2 can use SMB 3.0 share instead of a block storage (iSCSI/FC/etc). See:
Deploy Hyper-V over SMB
http://technet.microsoft.com/en-us/library/jj134187.aspx
There would be no shared disk and no CSV just SMB 3.0 folder both hypervisor hosts would have access to. Much simplier to use. See:
Hyper-V recommends SMB or CSV ?
http://social.technet.microsoft.com/Forums/en-US/d6e06d59-bef3-42ba-82f1-5043713b5552/hyperv-recommends-smb-or-csv-
You'll have however a limited solution as your single physical server being a file server would be a single point of failure.
You can use Storage Spaces just fine but you cannot use Clustered Storage Spaces as in this case you'll have to take away your SAS spindles from your R720 box and mount them into SAS JBOD (make sure it's certified). So you get rid of an active components
(CPU, RAM) and keep more robust all-passive SAS JBOD as your physical shared storage. Better then a single Windows-running server but for a true fault tolerance you'll have to have 3 SAS JBODs. Not exactly cheap :) See:

Alternative way would be using Virtual SAN similar to VMware VSAN in this case you can get rid of a physical shared storage @ all and use cheap high capacity SATA spindles (and SATA SSDs!) instead of an expensive SAS.
Hope this helped :)

Can not connect to a cluster and hyper-v manager(to one of my hosts) but virtual machines are running (hyperv2012r2)

Hello guys
I'm using a cluster hyper-v 2012 r2 with 9 hosts and after 12 hours without energy, it back again. my problem is:
my cluster do not back
all hyper-v hosts are and running hypervisor... all vms running... my problem is the cluster.... quorum do not back online...
i found the problem... the wmi is not working in one of my hosts and in that, i cant connect to this hyperv manager... from anywhere.... the virtual machines are running on this host... but i cant manage them...
i found an article talking about this and now, im running this script.... but nothing hapen

someone can help me?
tnx!

Tnx for the ansywer..
"When you say "my
cluster do not back" do you mean that the cluster is not running?"
yes... i cant connect to the cluster
Is "quorum
do not back online" another way you are saying the cluster is not running?
yes
Are you using disk witness or file share witness? Recommend
to use disk witness as it provides a more robust level of operation.
witness
Did you run the cluster validation wizard? Turn off the disk tests to prevent VMs from
failing over, but run all other tests. What errors/warnings do you get?
When i try to run validation tests, one of my hosts (same that i cant manage vitual machines), fail to join in tests but all others are tested

Failover Cluster, Hyper-V, Virtualised PDC and Time Sync

Hi,
I wonder if anyone can clear something up for me.
We have two hosts running failover cluster and hyper-v. On these hosts we two Virtual DCs (one of which is our PDC) as well as a number of member servers. In Hyper-V integration services we have set the time synchronisation option for each server including
the DCs. Each host is joined to the domain so that Failover Cluster works. We also have two physical domain controllers.
When we run w32tm /query /source we can see that the VMs, including the Virtual DCs are getting their time from the Hosts (VM IC Time Synchronization Provider) and when we run w32tm /query /source on the hosts we find that they are getting the time from
each other (host1 has host2 and host2 has host1).
We are experiencing some time drift and I wonder whether this is due to the PDC getting its time from the host, instead of having its w32time type parameter setup to be NTP instead of NT5DS?
What's the best practice for a situation like this??
Thanks in advance!
Stephen

yes, I was actually just digging the article out to post back but looks like you found it already.
i'm not aware of snapshot issues that you mention, its not something I've experienced, but if I was snapshotting a DC I would make sure if was running on 2012 hyper-v and the dc was also 2012, with the pdc being 2012 too. otherwise snapshotting a DC could cause
issues.

Hyper-v Failover Cluster management via powershell

Hi
We are looking at having a management server act as proxy for managing couple of hyper-v clusters using CSV. We plan to do management using powershell commands.
We create a session one of the host in the cluster and execute commands using invoke-command. The cluster verbs seems to fail with the following warning.
WARNING: If you are running Windows PowerShell remotely, note that some failover clustering cmdlets do not
work remotely. When possible, run the cmdlet locally and specify a remote computer as the target. To run the
cmdlet remotely, try using the Credential Security Service Provider (CredSSP). All additional errors or
warnings from this cmdlet might be caused by running it remotely.
What is the recommended way to do setup for using FailoverCluster ? We want to have a single management server that act proxy for all servers clustered or not.
Also, is there a document that describe various operations done via Failover Cluster Manager and corresponding powershell commands (or set of commands).
Thanks
/Jd

Regarding the Stop action from Failover Cluster Manager, Eric, I understand your point. But when I do shutdown from Failover Cluster Manager, the VM shuts down as expected even when the setting is set to Save.
I was very specifically talking about the Stop-ClusterGroup cmdlet, not any command issued in Failover Cluster Manager. But, well, yeah, if you tell a VM to shut down, it shuts down. I don't know why you'd expect anything different to happen. If you're looking
for the equivalent to Stop-ClusterGroup inside Failover Cluster Manager, it's not called "Shut Down". You can use "Stop Role" on the "More Actions" menu for the VM. You can also find the configuration object (usually named in the format of "Virtual Machine
Configuration XXX") and take it offline.
I tested a number of times after your first post, and Stop-ClusterGroup does what the Cluster-Controlled Action is set to every single time for me.
I could only make educated guesses at the underlying mechanics of FCM and PowerShell's cluster cmdlets, but the stand-out difference is that FCM has no method to operate in a double-hop situation at all, while PowerShell does. You only encounter these difficulties
with PowerShell in that second hop. The question you're asking: "it would be great to know how Failover Cluster Manager works without this setup ?" is an apples-to-oranges comparison.
This particular sentence of yours sort of changes the overall parameter of your question:
"... so our automation works..."
I was under the impression you were setting up this double-hop because you wanted admins to manually execute PowerShell cmdlets against your cluster from a single controlled location.
If automation is your goal, do it right from the cluster. I obviously don't know your entire wishlist and it's none of my business, but this double-hop situation may not be ideal.

Hyper-V Failover Cluster virtual guests suddenly reboots

The environment is Server 2012 R2 using dual clusters--a Hyper-V Failover Cluster running guest application virtual machines and a Scale-Out File Server Cluster using Tiered Storage Spaces which are used to supply SMB3 shares
for Quorum and CSV. Has anyone had this problem?

Anything relevant in the host or guest event logs? I would also check the cluster event logs to see if there are any indications there as well.
Does the guest go down hard or gracefully reboot?
Need more info.

Moving VMs from Standalone Hyper-V to Hyper-v Failover Cluster

Hello All.................I need to move Virtual Machines from Standalone Hyper-V based on Windows Server 2012 R2 to a Hyper-V Failover Cluster based on Windows Server 2012 R2.
- The VMs OS is Windows Server 2012 R2
- Applications installed on VMs are SCCM, SCOM, SharePoint, etc.
1. I am looking for a Checklist that I can run through and move them. To make sure I do not miss out anything.
2. Would a downtime be required in this scenario while the VM is being moved?
3. What requires special attention in this scenario?

Thanks for the reply.
So, I do not need to do anything and just simply add both the cluster and standalone into VMM and then simply use the Move option. Please, confirm if I have understood it correct.
Yes. But be carefull. First shut down your VM's
if possible and configure them in such a way they don't automatically start. If you install the SCVMM Agent, some Hyper-V related services are restarted, when some VMs start during that process you system may stall. I have seen this multipe times.
There is another dirty option that worked of us perfectly. Export the VMs. Then import those VMs to a local disk on one Hyper-V Server. Refresh the Hyper-V Server and Virtual Machines on that Hyper-V Server. Give it a few minutes. Then do
a Live Migration while at the same time makeing it "Highly Available" by moving it to your CSV. Works flawlessly. DO NOT IMPORT THE VMS TO YOUR CSV, otherwise you can't change it to "Highly Avaiable" unless you have
two CSVs. Importing it straight to a CSV does not make them Highly Available.

Removal of Node from Hyper-V Failover Cluster

Hello All....................I have a 8 node Hyper-V Failover Cluster based on Windows Server 2012 R2. I am facing some issues with one of the servers, so I have decided to take that node out of the Hyper-V Failover cluster. I would appreciate if someone
could share the steps that I should take to ensure smooth removal of node especially with respect to CSV Volume and Quorum. THanks.

Hi Sir ,
Please try the following command (before you do this please live migrate VMs to another nodes ):

Virtual memory in a hyper-v failover cluster

Hi all,
We have a window 2008 R2 hyper-V failover cluster working fine. It has two hosts, with 104 GB of memory on each of them.As I added new virtual instances I had been updating memory.
The point is that as I do that page file for virtual memory has been growing and now System volumen has only 20 GB free space.
I had like to go on adding memory for new virtual instances, so I need to fix this problem. Which is the recommended configuration for this? Can I disable virtual memory as long as I have an enormous quantity of physical memory available?
Thank you very much.
Kind regards,
David.

Hi,
that enormous page file at Hyper-V Servers make no sence.
We do not need to configure virtual memory for physical Memory that is assigned to VMs.

Heartbeat Network inside Hyper-V Failover Cluster

Dear All,
I need to build an SQL Server 2012 SP1 Two-node cluster inside Hyper-V Failover Cluster. There is only one virtual switch in the Hyper-V Failover Cluster environment which is being
used for communication to the outside world using VLAN Tagging. Now, since SQL Server 2012 Failover Cluster would require a heartbeat network as well and although possible to assign VLAN tag to the heartbeat adapter and use that for hearbeat, but since there
would not be any gateway on the heartbeat network, it would render the VLAN tagging useless, so is following plan good enough:
1. Create an Internal Virtual Switch on all nodes of the cluster with the same name
2. Link the heartbeat adapter of the virtual machines to the Internal Virtual Switch
Is it good enough? or is there any other better way?
Thanks in advance.

I am not an expert on this, but here is what I would do.
Create the VLAN and use that to keep the network setup as easy to understand as possible. Our Hyper-V cluster is only using IPv6 on the heartbeat network, and that is working like a charm. I would do the same inside the hyper-v hosts if I need to builld
a virtual cluster.
What is the reason for deploying a failover cluster for SQL inside Hyper-V? Wouldn't a log shipping "cluster" provide a more secure solution for your SQL?

Requirements for similar hardware in a 2012 Hyper-V failover cluster?

Simple question:
How similar does the hardware have to be on the host servers in a Windows Server 2012 Hyper-V failover cluster?
We have 6 dell servers that we are hoping to use for building a Windows 2012 Hyper-V cluster.
As I recall from our existing 2-host Hyper-V cluster, which is running on 2008 R2, there are fairly harsh demands in the cluster validation wizard with regard to similarity of hardware. So I am wondering if it will work?
The servers in question are 3 x R620, 2 x T410 and 1 x T610 Dell servers. So 3 x 12th generation servers and 3 x 11th generation servers
The servers all use Intel CPUs:
R620: Xeon E5-2670/2680
T410/610: Xeon X5650
and broadcom NICs:
T610: Broadcom 5709c
2 x T410: Broadcom 5716c
3 x R620: Broadcom 5720
Windows 2012 is supported by Dell on all the servers.
Shared storage will be on an SMB3 file share.

You'll be fine with a listed config no need to have identical machines. The only thing I'd try to change is use the same NICs all-around if possible.
P.S. Make sure you understand SMB share is a single point of failure unless SoFS or "old skool" NAS failover is configured. But it adds latency so using shared storage
directly w/o a file transport is FASTER and CHEAPER.
