Server 2008 R2 Failover cluster network configuration

Hi
We have a customer with a Server 2008 R2 Hyper-V failover cluster. They have 2 cluster networks, "Cluster Network 1" and "Cluster Network 2".
"Cluster Network 1": NIC team on 172.16.1.0/24 for private cluster network communication
"Cluster Network 2": NIC team on 192.168.1.0/24 for production network communication
I can see that "Cluster Network 1" is configured to "Allow cluster network communication on this network" and "Allow clients to connect through this network".
If "Cluster Network 1" is ONLY for communication between the to cluster nodes then I assume the selection in "Allow clients to connect through this network" should be removed?
/Lasse

It will cause a lost network connection for any client that is accessing through that network. Those clients would need to reconnect.
Did you configure both IPs on the cluster resource name that clients are accessing? If you only configured the one you want, there should be no issue. If you configured both, then it is possible some clients might be connected via the private
network.
Another thing you should, and if you have already done this you will most likely not have issues at all, is that you should disable DNS registration on any network you do not want client access coming through. If the clients can only find the resource
through the DNS name registered, that is the way they will be coming in. In my clusters, which often have 7 or more NICs, there is only one with a published DNS record.

MS DTC not coming online on SQL Server 2008 R2 failover cluster

Dear Experts,
On a SQL Server 2008 R2 failover cluster, MS DTC cluster service is not coming online. It fails with below error message.
"The DTC cluster resource's log file path was originally configured at: E:. Attempting to change that to: M:. This indicates a change in the path of the DTC cluster resource's dependent disk resource. This is not supported. The error code
returned: 0x8000FFFF".
From the Component Services, we can see under the clustered DTCs, in the properties of the log file that it is configured for E drive. The 'Transaction list' and 'Transaction Statistics' are empty. When I try to change the log file path to
point to M drive I get this warning message.
"An MSDTC log file already exists in the selected directory. Resetting an existing MS DTC log file may cause your databases and other transactional resource managers to become inconistent. Please review the MSDTC Administrator's manual before
proceeding. Do you wish to reset the existing MS DTC log"
Could you please advise if this is safe to proceed with this warning as the 'Transaction list' and 'Transaction Statistics' are empty or would it cause any other issue.
Thanks,
MM

Did you tried using wmi....win32_share
$path = "location where to create the folder"
$share = $Shares=[WMICLASS]'WIN32_Share' # class in wmi for share
$Sharename = 'Sharename'
New-Item -type directory -Path $Path
$Shares.Create($Path,$Sharename,0,255,$Sharename)
$Acl = Get-Acl $Path # cmdlet for getting access control list
$Access = New-Object system.security.accesscontrol.filesystemaccessrule("Username","FullControl","ContainerInherit, ObjectInherit", "None", "Allow")
$Acl.AddAccessRule($Access)
Set-Acl $Path $Acl

Server 2008 R2 failover cluster for DFS servers

A new client currently has a couple Server 2008 R2 failover clusters (one at each of their two primary sites) as their two hub DFS locations. I'm confused, and can't see much of a reason for this implementation, which only seems to introduce added complexity
with no real benefits. Here are my reasons:
- At each site, the servers in the failover clusters are on the same server VM farms, hosted on the same SAN's.
- The data hosted on each node of the clusters are not identical. For example, server1 has 25 DFS replicated folders and server2 has 20 replicated folders. In fact, the ~25 folders on server1 are all named <site>-user, and the ~20 folders on server
2 are <site>-data. There appears to be no crossover.
So if the SAN fails, they're screwed. If the VM host fails, they're screwed. Why not just have two DFS servers at each site for redundancy within each site, and replicating with other site DFS servers as needed? I'm not super strong with failover clustering
at all though, so I may easily be missing something.

Hi Steve,
From the description, as you said it seems create more factors which may cause a failure.
Using DFS on cluster could eliminate the possible of a single failing VM. However if the VM host is down, which will still leads to a failure. So actually the risk is still them same as just creating DFS namespace on these 2 VM hosts or any other file server.

MS- WIN SERVER 2008-R2 FAILOVER CLUSTER --ERROR 1127 ,1583

DEARS ,
I HAVE BEEN FACING PROBLEM FOR MY WINDOWS FAIL OVER CLUSTER SCENARIO.
THE ERROR CODES ARE 1127 AND 1583 WHICH ARE STATING THAT
All nodes IPv4 networks should be configured properly.
Nodes which are using Automatic Private IP Address (APIPA) for adapter Cluster.will not be added to the Windows Failover Cluster. If the adapter is to be used by Windows Failover Cluster, the IPv4 properties of the adapter should be changed to allow assignment
of a valid IP address that is not in the APIPA range.
However , I have checked that all of my NIC adapters have valid Static IP addresses. Also , when one of the nodes is down ,it cannot look for another node.
Please advise for the solution.

Hi,
Could you clarify your described “Nodes which are using Automatic Private IP Address (APIPA) for adapter Cluster.will not be added to the Windows Failover Cluster.” Did you
found one of your cluster node “automatically” have the APIPA address? If so, it seems is the IP conflict issue.
If it is not the IP address conflict issue, please try to disable your all the nodes firewall
or AV soft have the event 1583 typically cause by this function incorrect configured.

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.

Failover Cluster networking issue

Normally when configuring a SQL cluster you put the communication to the shared storage (usually a SAN) on a separate network, and so your config looks something like this (long live ms paint!):
So in this example the 192.168.100.0/28 subnet is used for cluster inter-communication (heartbeat) and for access to the shared storage. Access to the shared storage is kept completely isolated from the corporate network and everyone's happy.
On the corporate network side the cluster registers itself onto DNS on the 10.0.0.0/24 subnet and clients can resolver the cluster name and connect to it.
My configuration is slightly different though and I am having some problems with the networking side.
In my configuration my shared storage is a file server cluster with two nodes. So the "clients" of the file server cluster are the SQL servers themselves. As such, the network configuration should, as I see it, be something like this:
In this setup the SQL servers would still connect to the shared storage on a separate subnet, as per best practices, therefore keeping the cluster traffic separate from the corporate subnet.
However, for this to work the file server cluster IP address needs to be on the 192.168.100.0/28 subnet, and still be able to register on the DNS server on 10.0.0.0/24 subnet. Now this already involves setting up a lot more things than you would normally
on the cluster NICs, it is no longer just an IP address and a subnet mask, now you need a DNS server and a gateway, as well as ensuring that the DNS server is contactable from clients on the 192.168.100.0/28 subnet, meaning complete isolation is gone.
I can't find any best practices on how to get this done, and I don't think that the solution is to put this on a the cluster communication on the corporate network, nor to create a DNS server on the 192.168.100.0/28 subnet, so does someone have any ideas
how to get this done or how to improve the design of the setup?

Hi cogumel0,
In your case personal advice is you can add the additional NICs on SOFS computers and SQL cluster then make all this NIC at a same separate subnet such as 192.168.101.0/24,
disable the default settings with new added NICs: DNS register AND NetBios over TCPIP, then create a static DNS A record point to the new added NICs IP address.
Since the SQL on SMB storage only support the UNC path, we need create a another CAP On SOFS cluster (192.168.101.0/24 subnet CAP), after that we can create a static DNS A record
for this CAP and configure the SQL cluster access this CAP only.

How to install a database on a MS Windows 2008 R2 failover cluster?

Hello,
I have to install a Oracle 11g R2 database onto a MS cluster (Windows Server 2008 R2 Failover Cluster with 2 nodes and shared storage). I installed the DBMS on both nodes. On the first node, I created a tablespace, the files are on the shared storage. I can connect to that database, up to here everything is fine.
But the problem is: How do I have to configure the DBMS on the second node to use the existing database files in the case when the second node gets the Cluster IP and the shared storage? The switchover is done, all database files (in the filesystem) can be seen on the second node.
The goal is to connect to the database from an external application, regardless which node is active.
I know the "Oracle Fail Safe Manager", it is already installed on both nodes.
A link to the related documentation would be helpful, I can't find anything.
Best regards,
C. Jost

Hello,

The switchover is done, all database files (in the filesystem) can be seen on the second node.When you switch the database from one node to another one do you have any error ?
Can you connect to the database and check for the Tablespaces ?
Normally, with OFS you define Groups. In one Group you'll have the Database, the Disk, the IP address and the Listener. So when you move the Group from one node to another one, the disk will be recognized on the second node then, the database, listener, ... will start and, there's no reason to loose a datafile.
Please, find enclosed, an introduction to Oracle Fail Safe concept:

Redirect print server webpage in a 2008 R2 Failover Cluster.

I am configuring a 2 node 2008 R2 Failover Cluster with print services as a resource. On a client, i can install a printer by going to the website http://virtualprintserver.domain/printers/, selecting a printer and click on connect.
To prevent showing the default IIS page, i want to redirect http://virtualprintserver.domain to http://virtualprintserver.domain/printers/.
How can i achieve this? I have searched in IIS manager, but could not find anything.
Thank you for your help.

Solved!
After consulting a colleague with web design knowledge we came up with the following solution:
Go to %SystemDrive%\inetpub\wwwroot\
Rename iisstart.htm in iisstart.htm.old
Create a new index.htm file with the code: <html><head><title></title><meta http-equiv="refresh" content="0;URL=http://virtualprintserver.domain/printers" /></head><body></body></html>
Reset IIS

Microsoft update KB 3002657 and 2008 R2 failover cluster for virtualization

After installing Microsoft update KB 3002657 on my Windows 2008 R2 failover cluster for virtualization, nodes in cluster lost connection to CSV and all my VM's were moved to node owning the volume.
I lost whole day to solve that problem.
But should i keep that update not installed on cluster nodes or anyone maybe has a solution for that ?

Hi a3pl,
Unfortunately, the available information is not enough to have a clear view of the occurred behavior from the cluster perspective. Please offer us
more information such as the failover cluster validation error, the failover error event ID, with the current information it is difficult to presume which part may cause this issue, we strongly suggest you install the following update when you use failover
cluster.

VSA Manager 5.1 stuck in "Validating VSA Cluster Network Configuration"

Hi all!
I am experiencing a problem with VSA Manager 5.1.3.0 running on a Win2008R2 server with vCenter 5.1 build 1123961. When I open the VSA Mananger tab in the VI Client it displays "Validating VSA Cluster Network Configuration".
When trying to close the window it says:
I have tried to open the VSA Manager tab on another server with the VI Client installed but the result is the same. I have also tried to upgrade the VSA Manager to 5.5 but it stayed the same.
The cluster with the VSA nodes is working normally but I cannot manage VSA or upgrade the environment. Any advice or help would be greatly appreciated!
Best regards

Witness Server in a failover cluster

Hi.
I was reading about this witness server in a failover cluster but always thought that the switch between active and passive would be automatic, never thought of a "vote" and a "quorum" to reach.
Under what circumstances do I need this quorum (and therefore a witness server) and what happens if I am even?
Does a witness server have necessarily to be a third one or can be set up as either the active or the passive one?
Cheers

Hi,
In addition to Jared's suggestion, I would like to clarify the following things:
1. The witness server and its directory are used only for quorum purposes where there's an even number of members in the DAG.
2. The witness server should be in the same Active Directory forest as the DAG.
3. It is recommended to specify a Client Access server as the witness server for Exchange 2013 DAG.
Hope my clarification is helpful.
If there are any problems, please feel free to let me know.

Mac10.x client can't connect to File Server on Windows2008 Failover Cluster

Installation of a cluster was made according to the document "Failover Cluster Step-by-Step Guide: Configuring a Two-Node File Server Failover Cluster " http://technet.microsoft.com/en-us/library/cc731844.aspx.
My Mac OS X 10.5.2 and Mac OS X 10.4.11 clients be able to connect to a non-cluster file server on a Windows 2008 (the File Services role) and also to old file cluster on a Windows 2003.
Why Mac clients can't connect to Windows 2008 Failover Cluster?

Are you running a firewall on the Macs. If yes does it work with out the firewall? If it works with out the firewall that means you will have to create a custom ipf rule which includes the both the physical an virtual IP addresses of your cluster.

Question on Cluster network configuration

Hi Guys,
Just wanted to know the best practices for configuring network for clusters.
As far as I know, recommended is to have a separate network for Public/client communications and separate network for private heartbeat communication.
Does this change for Win 2008 & Win 2012 Clusters? I say this because I heard that there is no more need to have 2 dedicated networks and only 1 network is enough.
Is this true? If it is true , does it not a single point of failure ? What is the best practices for configuring sql clusters?
Thanks in advance.
