Server 2012 Failover cluster. Make two VMs stay on the same node
We have a unique situation where i need two machines to stay on the same node. Its a 4 node cluster with 30+ resources but i want to make sure two boxes are ALWAYS on the same now. If one migrates to another node the second needs to follow. Is there
a way to do this?
How an this KB help to stay the two vm's on the same node.
With all do respect @justinv how could this helped you to your problem , your question was "We have a unique situation where i need two machines to stay on the same node. Its a 4 node cluster with 30+ resources but i want to make sure two boxes are ALWAYS
on the same now"
and the KB that elden showed you is for : "Failover clusters that are running inside of virtual machines (sometimes referred to as “guest clusters”) may have problems with nodes joining the cluster."
@justinv cloud you tell us more about this did I misunderstand your question ?
Greetings, Robert Smit Follow me @clustermvp http://robertsmit.wordpress.com/ “Please click "Vote As Helpful" if it is helpful for you and Proposed As Answer” Please remember to click “Mark as Answer” on the post that helps you
I explained in one of my replies that my underlying issue was this exactly what the KB fixed..... A guest cluster failing when moved to different nodes. Thats the only reason why i wanted them on the same node to begin with. While this post didn't solve me
original question is solved what my real problem was....

SQL Server 2012 Failover Cluster configuration questions
Hi,
I have few questions on , SQL Server 2012 Failover cluserting pleasse provide suggestions:
1) In SQL Server 2012 is there a configuration for active / passive Failover Cluster installation? If so how is it done? if you could provide any links or articles that would help.
OR
Is this been replaced by Always ON Availability Groups?
2) Also in our environment we have done active/active installation but at a time my understanding is only node has the ownership to the shared storage versus both the nodes, is that correct? If not please provide an explanation?
Any additional information would be valuable in clearing my doubts?
Thank youy
Malini=Hi malinisethi,
If you install SQL Server in a cluster and configure Active-Passive cluster. In the first node, select “New SQL Server Failover Cluster installation” option , when we are installing Active-Passive cluster, we have to specify one virtual/network name. (Note:
For Active-Active clustering you have specify different network names as per the number of nodes). on the other nodes is similar to installing on the first node except that we have select the Add Node to a SQL Server failover cluster option from the initial
menu. For more information, there is a similar issue about SQL Server 2008 Active-Passive/Active-Active cluster installation, you can review the following article.
http://sqldbpool.com/2009/10/07/sql-server-2008-active-passive-cluster-installation/
About Active/Active SQL Cluster, two clustered SQL Server instance are created in different nodes. Then apply Active /Active configuration of both instance. There is an example about creating an Active/Active SQL Cluster using Hyper-V. you can review the
following article.

How Can I create a cluster of two instances running on the same server?
Hello,
I can't find how to create a cluster or even a failover rule for my two instances running on the same server ODSEE 11gR1.
Could you please help?
Thanks,Hello,
Clustering (intended as Sun Cluster, Veritas Cluster, etc... ) IS NOT SUPPORTED since 7.0:
http://docs.oracle.com/cd/E20295_01/pdf/821-1216.pdf [page 20]
and, based on my own experience, is the WORST way of achieving high availability of an LDAP Directory Service and an almost GRANTED way to get replication issues in your topology (lock, split, re-init, etc...).
Please use instead the 'application-level' clustering that you get out of the box with the Multi-Master Replication.

I have two windows 2012 host server that are clustered using windows failover cluster feature. Each server is hosting four VMs. When migrating from Host2 to Host1, the migration failed with the following error:
Cluster resource 'Virtual Machine Configuration SCPCSQLSRV01' of type 'Virtual Machine Configuration' in clustered role 'SCPCSQLSRV01' failed. The error code was '0x569' ('Logon failure: the user has not been granted the requested logon type at this computer.').
When this happens, the VM that I was migrating can no longer be started even on the original host. The only remedy is to restart the host server.
Any suggestion on resolving this problem?
Thanks
IkadThanks. The article referred to above gives the solution to my issue. There is a group policy that is applied to the OU where the host servers were placed. Doing gpupdate /force temporarily removes the problem. Unfortunately the NT Virtual Machine\Virtual
Machines account is a special account that cannot be added like other accounts and granted the log on as a service right. The thread
http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/d56f2eae-726e-409a-8813-670a406593e8 contains how it can be added which is by creating a group and running the command
Net localgroup VMTest “NT Virtual Machine\Virtual Machines” /add
to add it to a local group VMTest. VMTest is then assigned the right to log on as a service.

Server 2012 Failover Cluster No Disks available / iSCSI
Hi All,
I am testing out the Failover Clustering on Windows Server 2012 with hopes of winding up with a clustered File Server once I am done.
I am starting with a single node in the cluster for testing purposes; I have connected to this cluster a single iSCSI LUN that is 100GB in size.
When I right click on Storage -> Disks and then click 'Add Disk', I get No disks suitable for cluster disks were found.
I get this, even if I add a second server to the cluster, and connect it to the iSCSI drive as well.
Any ideas?Hi All,

For testing purpose you'd better spawn a set of VMs on a single physical Hyper-V host and use shared VHDX as a back clusterd storage. That would be both much easier and much faster then what you do. + it would be trivial move one of the VMs to another physical
host, shared VHDX to CSV on a shared storage and go from Test & Development to production :) See:
Shared VHDX

For a pure iSCSI scenario you may try this step-by-step guide (just skip StarWind config as you do have a shared storage already with your SAN). See:

SQL Server 2012 Failover Cluster Setup
I have to set up a Lab Test environment for SQL Server 2012 with failover clustering. What are the most cost effective specifications for H\W & S\W. AFAIK Apart of Enterprise edition, Standard edition can support failover clustering for upto
2 nodes with one node in passive mode. Somewhere (Here) I got that it is possible to configure SQL Server failover clustering On SQL
Server 2012 Developer edition. Also Is it possible to use Windows 7 Platform with SQL Server 2012 Developer Edition for configuring Always on Failover Clustering. Although I have researched alot, but puzzled. Seeking for experts advise. Thanks in advance.
Pranshul GuptaYes you can configure and install in windows 7.. but make sure you have made all the proper updates as per the microsoft suggestion..

Win Server 2012 Failover Cluster - Error: Failed to bring cluster disk online
Hi Technet
I'm currently running running 2 VMs Win Server 2012 and would like to test Failover Clustering for one of our FTP server
I've added on both servers an additional partition, formatted and Online
One of the drives comes Online but cannot bring the 2nd disk online from the cluster manager
Error: failed to bring resource online - clustered storage is not connected to the node
Assistance would be greatly appreciated
Thank you
JabuHi jsibeko,
Since the VMware offer the MSCS shared storage solution themselves, I suggest you first ask VMware whether that shared storage is supported with your vSphere edition, I found
some VMware KB about the VMware shared storage for MSCS, may you can get more tips.
The VMware KB:
Microsoft Clustering on VMware vSphere: Guidelines for supported configurations (1037959)

Windows Server 2012 Failover Cluster (Hyper-V) Event Id 1196
Hi All,
I just installed Failover Cluster for Hyper-V on windows server 2012 with 2 nodes. I got following error event id 1196.
reCreated / deleted Cluster Host A record on DNS and nothing happened.
Any suggestion?
There is similar topic but it couldnt help
http://social.technet.microsoft.com/Forums/en-US/winserverClustering/thread/2ad0afaf-8d86-4f16-b748-49bf9ac447a3/
RegardsHi,
You may refer to this article to troubleshoot this issue;
Event ID 1196 — Network Name Resource Availability
http://technet.microsoft.com/en-us/library/dd354022(v=WS.10).aspx
Check the following:
Check that on the DNS server, the record for the Network Name resource still exists. If the record was accidentally deleted, or was scavenged by the DNS server, create it again, or arrange to have a network administrator create it.
Ensure that a valid, accessible DNS server has been specified for the indicated network adapter or adapters in the cluster.
Check the system event log for Netlogon or DNS events that occurred near the time of the failover cluster event. Troubleshooting these events might solve the problem that prevented the clustered Network Name resource from registering the DNS name.

How to make two Application Modules share the same entity cache?
Hello everyone, I am using JDeveloper 11.1.2.3.0
I have a little problem in my application through using two AppModules that contain also same ViewObjects. So to be clear one VO is declared in two AppModules. When I commit the view by using AppModule1 and then go to another page that uses the same VO but from AppModule2, I have to commit again, even through the row is previously stored in the database.
I understood that this came because different AppModules use different entityCache for database communications.
I am asking if anyone knows any option on how to sync the entity caches from the two appmodules, or how to make them use the same entity cache.
Thank youYou can make a copy of the app and give it another name, but it will use the same settings files no matter which you open. Settings aren't stored in the app, but in your Preferences.
Firefox, being a Windows derivative, might have the capability to use "Profiles" where you'd set it up different for each profile. I don't use Firefox, so I don't know if that option exists. -
How to make two Range Selection at the same time?
In a single clip, at the same time, in two locations, I would like to have Range Selection. Then I would like to switch between the two and play within the range one after the other immedeately. Is this possible? Thanks.

You can mark multiple range selections in a clip by clicking and dragging with the Command key down – or marking in and out points with Shift+Command.
I don't know what you mean when you say "at the same time".
Then I would like to switch between the two and play within the range one after the other immedeately. Is this possible? Thanks.
Forward slash plays betweeen the in and out. The only way I know to play them one after the other "immediatelly" is to edit the two selections to the timeline.

Virtual Domain Controllers in 2012 Failover Cluster. Time Skew
Hi All,
Not sure if this is the correct space for this topic, however i'll give it a go anyway.
We have a 2 Hosts (HP DL385) Windows Server 2012 Failover Cluster.
Storage is provided by a 12 Bay NAS with iSCSI connections (This is catering for CSV's and Quorum)
We are running 2 Virtual domain controllers (2008R2)
The issue we experience is that if the cluster goes down, and when it comes back online the time on the domain controllers (one or the other or both) skews by any where up to 3 days which causes havoc for our office until we can resync clocks with the PDCe.
Time Synchronisation Integration Service is disabled on both Domain Contollers
A few days back we need to reboot the storage on the cluster, and the tasks performed were as follows:
-Power off all virtual machines (Graceful Shutdown)
-Put all CSV's into maintenance mode
-Offline Disk Witness to Quorum
-Rebooted Storage (Waited until it came back online)
-Online Quorum Storage (Successful)
-Bring CSV's out of maintenance mode (Successful & Browsable)
-Power on all Virtual Machines (Successful)
This is where the time Skewed and caused headaches. The time for some reason went to 2 days 11hrs in the past on 1 domain controller.
With this DNS lookups failed to work, Cluster services failed, Cluster Aware Updating Failed, RDP to VM's (and Virtual Hosts) by DNS Name failed (Date time error)
There doesn't seem to be anything in the EventLog except for date/time stamp on events being 2 days in the past.
Now this is why i'm not sure if the issue is cause by fail over clustering, or is an issue with the domain controllers.
Any advice regarding this or if anyone has seen this behaviour before any info would be great
Thanks
RobHi Rob,
Does both this two DCs on your cluster VM and there have not others DCs? Microsoft recommends that files for virtualized domain controllers be placed on non-CSV
disks, Non-CSV disks can be brought online without authentication. Because non-CSV disks can be brought online more easily.
For virtual machines that are configured as domain controllers, it is recommended that you disable time synchronization between the host system and guest operating
system acting as a domain controller. This enables your guest domain controller to synchronize time from the domain hierarchy, please confirm your PDC time is always correct.

FTP in Windows 2012 Failover Cluster
Hi,
Understand that Windows 2012 is having much improved Failover Clustering features,however i have faced issues when i configured FTP in Windows 2012 Failover Cluster.
1) As per the process configured the shared disk for FTP data path.
2)Installaed FTP feature in both Nodes of Clustert
3)Finally created the Generic Service in Cluster Roles for FTP Service.
After the configuration i found everything working fine but when i try to failover the FTP role found that FTP resource is not moving smoothly. Also i observed that Microsoft FTP service gets in to "starting" mode in the destination Node. To run the FTP
resource Microsft FTP service should be in Started mode.
This happens only when we try to failover else it works fine if you start freshly.
Have any one tried this? Any clue about such issue ?
Regards:MaheshHi,
In earlier versions of Internet Information Services, Microsoft provided generic resource monitor components to support high availability Web server instances by using the Microsoft Clustering infrastructure. However, custom code was needed to fully realize
the potential of this solution. Also, the generic scripts that Microsoft provided did not satisfy customer needs.
From IIS 7 to configure IIS in a clustered environment by using Windows Server failover clustering, you have to use a custom (scripting) code to enable such a high availability scenario.
Note:
We recommend that administrators carefully evaluate the use of Network Load Balancing (NLB) instead of using failover clustering as the primary and preferred method for improving the scalability and availability of Web applications that have multiple servers
that are running new IIS (from IIS 7) . One benefit of NLB is that all servers can actively participate in the concurrent handling of incoming HTTP requests. Another benefit is that in an NLB IIS environment, it can be much easier to support rolling updates
and rollbacks while still providing high availability of Web applications.
To configure high availability for IIS FTP servers using Failover Clustering:
Install the Web Server role on all cluster nodes.
Install the Failover Clustering feature on all cluster nodes and create the cluster.
Set up a file share that will be used for IIS shared configuration
Configure the IIS shared configuration on all cluster nodes
Configure Offline Files for IIS Shared Configuration on all cluster nodes
Configure the FTP site and specify the location of its content on one cluster node
Configure high availability for your FTP site by creating a generic script in Failover Cluster Manager
For more detailed configuration procedure please refer to following MS articles:
Note: I didn’t find IIS 8 in Windows Server 2012 failover cluster configuration guide, below guide was published for II 7 in Windows server 2008 and Windows Server 2008 R2, but its basis configuration procedures should also apply to Windows Server 2012.

Windows 2012 Failover Cluster - File server role (vCO)
Hi,
I wonder if anybody can shed some light on a query i have.
A windows 2012 failover cluster will be built in AD domain example.uk. Cluster File server roles will be created and will reside in this domain also.
We also have a requirement to run a cluster file server role in the child domain off secure.example.uk. Is this possible? or do the file server roles and related vCO's have to reside in the same domain as the cluster (CNO).
I know the CNO can be used to create the VCO but could a prestage a VCO in the child domain of secure.example.uk.
MarkHi Mark,
By default CNO will create
VCO automatically in default domain computer OU, we generally use the
KISS principle to place the CNO and VCO to the same OU, and as far as I know there no known design document indicate the VCO can be placed in different domain, therefore I suggest you place the CNO and V CO at same OU.
