I had created 2 VMs with Windows Server 2008 Enterprise(Server core) as the operating system.
Follow the below steps to prepare the Nodes to form failover cluster. Required command to achieve the goal is given for each step.
1. Get the computer Name.
2. Change computer Name. (This would require a reboot.)
NETDOM RENAMECOMPUTER <machinename> /NEWNAME:newmachinename
To reboot the server: SHUTDOWN –r –t 0
3. Set the IP configuration
NETSH INTERFACE IPV4 SET ADDRESS NAME= ”Local Area Connection” STATIC 192.168.1.10 255.255.255.0
NETSH INTERFACE IPV4 ADD DNSSERVERS ”Local Area Connection” 192.168.1.1
4. Join the Node to the domain
NETDOM JOIN <NodeName> /DOMAIN: <domain name> /UserD:domain\Administrator /Passwordd:*
Reboot the server after joining it to domain.
Repeat the steps for Other Nodes as well.
LISTDISK (this will return the disks available in your system. (Disk 0 being the OS disk normally.)
Further steps will select the target disk, clear the readonly attribute, bring it online and create an NTFS partition
SELECT DISK 1
ATTRIBUTE DISK CLEAR READONLY
CREATE PART PRIMARY
SELECT PART 1
Repeat the steps for other disks. Put the Disk Number and Drive letter accordingly.
Quit DISKPART. Format each disk by typing FORMAT D: /q where D is your Drive letter. No need to provide any label.
The servers are now completely configured to form a Windows Server 2008 R2 Failover Cluster.
In Windows Server 2008 R2 we are introducing PowerShell as the new scripting language for clustering technologies. PowerShell with Failover Clustering will replace Cluster.exe and the Windows Server 2008 R2 release will be the deprecation release for Cluster.exe. This means it will still be available for use so it doesn’t break legacy scripts, but no improvements have been made and Cluster.exe will be completely removed in the next release of Windows Server.
By default, Windows PowerShell is not installed on a computer that is running Windows Server 2008 R2 Core. You can use the below method to install Windows PowerShell on a computer that is running Windows Server 2008 R2 Core.
You could use OCLIST command to find which all features/Roles are already installed.
Use OCSETUP to install the required Features
Start /w OCSETUP FailoverCluster-Core
Start /w OCSETUP FailoverCluster-Core-WOW64
Also add additional Features/Roles that you was Cluster Services.
In this scenario I have added File Server and DFSR roles
Start /w OCSETUP CoreFileServer
Start /w OCSETUP DFSNServer
Start /w OCSETUP DFSR-Infrastructure-ServerEdition
You may also use DISM /Online /Get-Features command to list the features.
And to install features you can use DISM /Online /Enable-Feature /FeatureName:<featureName>
Example: DISM /Online /Enable-Feature /FeatureName: MicrosoftWindowsPowerShell
Repeat the tests on other Nodes as well.
In Windows Server® 2008 and Windows Server 2008 R2, the way that clusters are qualified is changing significantly with the introduction of the cluster validation wizard. The cluster validation wizard is a feature that is integrated into failover clustering in Windows Server 2008 and Windows Server 2008 R2. With the cluster validation wizard, you can run a set of focused tests on a collection of servers that you intend to use as nodes in a cluster. This cluster validation process tests the underlying hardware and software directly, and individually, to obtain an accurate assessment of how well failover clustering can be supported on a given configuration.
A cluster validation report is required by Microsoft® Customer Support Services (CSS) as a condition of Microsoft supporting a given configuration.
To run the cluster validation tests using Power shell in Windows Server 2008 R2 Core:
1. Start Power shell and import the Failover Cluster module
2. Run the cluster Validation against the proposed cluster nodes
TEST-CLUSTER –NODE Node1,Node2
To create a Failover Cluster using Power shell in Windows Server 2008 R2 Core:
2. Create the cluster with the proposed cluster nodes
NEW-CLUSTER –NAME “CoreCluster” –NODE Node1,Node2,Node3 –STATICADDRESS 192.168.1.15
Wait for the Failover Cluster configuration to be complete.
Note: You may also perform these steps from a Windows Server 2008 R2 Full version using Failover Cluster Management RSAT tools.
Let’s discuss few commands to manage your Server Core failover cluster
Let’s try adding a File server Service to the Failover Cluster.
Move-ClusterGroup CorePrintServer -Node node2
This command moves the clustered service called MyPrintServer from the current owner node to node2.
Get-ClusterNode node3 | Get-ClusterGroup | Move-ClusterGroup
This command moves all clustered services and applications (resource groups) that are currently owned by node3 to other nodes. You can use this command before performing maintenance on the specified node.
Move-ClusterGroup CorePrintServer -Node node2 -Wait 0
This command moves the clustered service (resource group) called MyPrintServer from the current owner node to node2. Information about MyPrintServer is displayed immediately, while it is in the process of being moved.
Get-Cluster CoreCluster | Add-ClusterNode node3
This command adds node3 to cluster1.
