Migrating clustered services and applications to a new failover cluster. Use the following instructions to migrate clustered services and applications from your old cluster to your new cluster. After the Migrate a Cluster Wizard runs, it leaves most of the migrated resources offline, so that you can perform additional steps before you bring them online.
If the new cluster uses old storage, plan how you will make LUNs or disks inaccessible to the old cluster and accessible to the new cluster but do not make changes yet. To open the failover cluster snap-in, click Administrative Tools, and then click Failover Cluster Manager. In the console tree, if the cluster that you created is not displayed, right-click Failover Cluster Manager, click Manage a Cluster, and then select the cluster that you want to configure.
In the console tree, expand the cluster that you created to see the items underneath it. If the clustered servers are connected to a network that is not to be used for cluster communications for example, a network intended only for iSCSI , then under Networks, right-click that network, click Properties, and then click Do not allow cluster network communication on this network. Click OK. In the console tree, select the cluster.
Click Configure, click Migrate services and applications. Read the first page of the Migrate a Cluster Wizard, and then click Next. Specify the name or IP Address of the cluster or cluster node from which you want to migrate resource groups, and then click Next. Click View Report. The wizard also provides a report after it finishes, which describes any additional steps that might be needed before you bring the migrated resource groups online. Follow the instructions in the wizard to complete the following tasks:.
Choose the resource group or groups that you want to migrate. Specify whether the resource groups to be migrated will use new storage or the same storage that you used in the old cluster. If the resource groups will use new storage, you can specify the disk that each resource group should use.
Note that if new storage is used, you must handle all copying or moving of data or folders—the wizard does not copy data from one shared storage location to another. If you are migrating from a cluster running Windows Server that has Network Name resources with Kerberos protocol enabled, specify the account name and password for the Active Directory account that is used by the Cluster service on the old cluster. After the wizard runs and the Summary page appears, click View Report.
When the wizard completes, most migrated resources will be offline. Leave them offline at this stage. Completing the transition from the old cluster to the new cluster. You must perform the following steps to complete the transition to the new cluster running Windows Server Prepare for clients to experience downtime, probably brief.
Take each resource group offline on the old cluster. Complete the transition for the storage:. If the new cluster will use old storage, follow your plan for making LUNs or disks inaccessible to the old cluster and accessible to the new cluster. If the new cluster will use new storage, copy the appropriate folders and data to the storage. As needed for disk access on the old cluster, bring individual disk resources online on that cluster.
Keep other resources offline, to ensure that clients cannot change data on the disks in storage. Also as needed, on the new cluster, use Disk Management to confirm that the appropriate LUNs or disks are visible to the new cluster and not visible to any other servers. If the new cluster uses mount points, adjust the mount points as needed, and make each disk resource that uses a mount point dependent on the resource of the disk that hosts the mount point.
Bring the migrated services or applications online on the new cluster. To perform a basic test of failover on the new cluster, expand Services and Applications, and then click a migrated service or application that you want to test.
To perform a basic test of failover for the migrated service or application, under Actions on the right , click Move this service or application to another node, and then click an available choice of node. You can observe the status changes in the center pane of the snap-in as the clustered service or application is moved. If there are any issues with failover, review the following:. View events in Failover Cluster Manager. To do this, in the console tree, right-click Cluster Events, and then click Query.
In the Cluster Events Filter dialog box, select the criteria for the events that you want to display, or to return to the default criteria, click the Reset button. To sort events, click a heading, for example, Level or Date and Time. Confirm that necessary services, applications, or server roles are installed on all nodes.
Confirm that services or applications are compatible with Windows Server R2 and run as expected. If you used old storage for the new cluster, rerun the Validate a Cluster Configuration Wizard to confirm the validation results for all LUNs or disks in the storage.
Review migrated resource settings and dependencies. If you migrated one or more Network Name resources with Kerberos protocol enabled, confirm that the following permissions change was made in Active Directory Users and Computers on a domain controller. In the computer accounts computer objects of your Kerberos protocol-enabled Network Name resources, Full Control must be assigned to the computer account for the failover cluster.
Migrating Cluster Resource with new Mount Point. When you are working with new storage for your cluster migration, you have some flexibility in the order in which you complete the tasks.
The tasks that you must complete include creating the mount points, running the Migrate a Cluster Wizard, copying the data to the new storage, and confirming the disk letters and mount points for the new storage. After completing the other tasks, configure the disk resource dependencies in Failover Cluster Manager.
A useful way to keep track of disks in the new storage is to give them labels that indicate your intended mount point configuration. This assumes that the label Mount is not already in use in the old storage. Then when you run the Migrate a Cluster Wizard and you need to specify that disk for a particular migrated resource, you can look at the list and select the disk labeled Mount Then you can return to Failover Cluster Manager to configure the disk resource for Mount so that it is dependent on the appropriate resource, for example, the resource for disk F.
Similarly, you would configure the disk resources for all other disks mounted on disk F so that they depended on the disk resource for disk F. A failover cluster is a group of independent computers that work together to increase the availability of applications and services. The clustered servers called nodes are connected by physical cables and by software.
If one of the cluster nodes fails, another node begins to provide service a process known as failover. Users experience a minimum of disruptions in service. This guide describes the steps that are necessary when migrating a clustered DHCP server to a cluster running Windows Server R2, beyond the standard steps required for migrating clustered services and applications in general.
The guide indicates when to use the Migrate a Cluster Wizard in the migration, but does not describe the wizard in detail. Step 1: Review requirements and create a cluster running Windows Server Before beginning the migration described in this guide, review the requirements for a cluster running Windows Server R2, install the failover clustering feature on servers running Windows Server R2, and create a new cluster.
Step 2: On the old cluster, adjust registry settings and permissions before migration. To prepare for migration, you must make changes to registry settings and permissions on each node of the old cluster. Confirm that you have a current backup of the old cluster, one that includes the configuration information for the clustered DHCP server also called the DHCP resource group.
Confirm that the clustered DHCP server is online on the old cluster. It must be online while you complete the remainder of this procedure. On a node of the old cluster, open a command prompt as an administrator. Choose the option that applies to your cluster: If the old cluster is running Windows Server , skip to step 7. Right-click Parameters, and then click Permissions. Click Add. Locate the appropriate account and assign permissions:. Under Enter the object names to select, type Everyone, and then click OK and confirm your choice if prompted.
Under Group or user names, select Everyone and then select the check box for Full Control. Repeat the process on the other node or nodes of the old cluster. Step 3: On a node in the old cluster, prepare for export, and then export the DHCP database to a file. This requires preparatory steps that prevent the cluster from restarting the clustered DHCP resource during the export. Start display at page:. Lorraine Walters 7 years ago Views:.
