If you have problems with partitions on the disk or corruption, we recommend that you run Chkdsk so that it can correct any problems with the file system. Confirm that the mounted disk is configured according to the following guidelines:. Clustered disks can only be mounted onto clustered disks not local disks ;.
The mounted disk and the disk it is mounted onto must be part of the same clustered service or application. They cannot be in two different clustered services or applications, and they cannot be in the general pool of Available Storage in the cluster. Event ID: , , , , , Confirm witness accessibility by viewing the quorum configuration of a failover cluster and the status of a witness disk. When the cluster configuration on a node is missing or corrupt, the Cluster service cannot load the configuration and therefore cannot start.
Where possible, the Cluster service will obtain the latest cluster configuration from other nodes in the cluster. Ensure that other nodes are started. If the only node or nodes that can be started appear to have a missing or corrupt cluster configuration database, you will probably need to restore one of the nodes from a system state backup.
For a failover cluster node, the system state backup includes the cluster configuration. Sometimes when the node attempts to unload the cluster configuration database, the action does not fully complete.
Try stopping and restarting the Cluster service. If this does not succeed, restart the operating system on the affected node. Event ID: , , Check DFS namespace configuration. Returns the number of events when encrypted settings for a cluster resource could not be successfully applied to the container on this node.
Close any application that might have an open handle to the registry checkpoint indicated by the event. This will allow the registry key to be replicated as configured with the resource properties. If necessary, contact the application vendor about this problem. You can use a utility called Handle with the -a option to view handles to the registry. You might be able to correct this issue by restarting the Cluster service. Event ID: , , , , , , , , Confirm that the share exists and that the permissions allow access to the share.
If possible, determine whether the path to the share has been changed. If so, recreate the share with the correct name. View all the resources in the clustered file server instance to ensure that they are coming online, and review the dependencies among the resources.
Reconfigure as necessary to correct any problems. Returns the number of events that occur when a generic application could not be brought online during an attempt to create the process due to; the application not being present on this node, an incorrect path name, or an incorrect binary name. Confirm that the following are true for the application used by the clustered Generic Application instance:.
Confirm that the correct service is specified in the configuration for the Generic Service resource and confirm that the service is fully installed on all nodes that are possible owners of the resource. Check the address, subnet, and network properties of the IP Address resource. If the IP Address resource appears to be configured correctly, check the condition of network adapters and other network components used by the cluster. Correct any problems with the physical network adapters and the cluster virtual adapter.
To install the failover cluster management tools, select Add Features , and then select Next. On the Confirm installation selections page, select Install. A server restart is not required for the Failover Clustering feature. After you install the Failover Clustering feature, we recommend that you apply the latest updates from Windows Update.
Also, for a Windows Server based failover cluster, review the Recommended hotfixes and updates for Windows Server based failover clusters Microsoft Support article and install any updates that apply.
Before you create the failover cluster, we strongly recommend that you validate the configuration to make sure that the hardware and hardware settings are compatible with failover clustering. Microsoft supports a cluster solution only if the complete configuration passes all validation tests and if all hardware is certified for the version of Windows Server that the cluster nodes are running. You must have at least two nodes to run all tests.
If you have only one node, many of the critical storage tests do not run. On the Select Servers or a Cluster page, in the Enter name box, enter the NetBIOS name or the fully qualified domain name of a server that you plan to add as a failover cluster node, and then select Add. Repeat this step for each server that you want to add.
To add multiple servers at the same time, separate the names by a comma or by a semicolon. For example, enter the names in the format server1. When you are finished, select Next. On the Testing Options page, select Run all tests recommended , and then select Next. If the results indicate that the tests completed successfully and the configuration is suited for clustering, and you want to create the cluster immediately, make sure that the Create the cluster now using the validated nodes check box is selected, and then select Finish.
Then, continue to step 4 of the Create the failover cluster procedure. If the results indicate that there were warnings or failures, select View Report to view the details and determine which issues must be corrected. Realize that a warning for a particular validation test indicates that this aspect of the failover cluster can be supported, but might not meet the recommended best practices.
If you receive a warning for the Validate Storage Spaces Persistent Reservation test, see the blog post Windows Failover Cluster validation warning indicates your disks don't support the persistent reservations for Storage Spaces for more information.
For more information about hardware validation tests, see Validate Hardware for a Failover Cluster. To complete this step, make sure that the user account that you log on as meets the requirements that are outlined in the Verify the prerequisites section of this topic. If the Select Servers page appears, in the Enter name box, enter the NetBIOS name or the fully qualified domain name of a server that you plan to add as a failover cluster node, and then select Add.
To add multiple servers at the same time, separate the names by a comma or a semicolon. If the cluster nodes are also DNS servers, " On the DNS tab, verify that there are no values defined. When you close the dialog box, you may receive the following prompt. If you receive this prompt, click Yes :. Click the cluster name at the root of Administrator. On the File menu, click Properties. On the Network Priority tab, verify that the private network is listed at the top.
If it is not, use the Move Up button to increase its priority. Click Internal cluster communications only private Network. For more information, see How to use Windows Server cluster nodes as domain controllers. On the IP Address tab, verify that you have selected a static IP address that is not on the same subnet or network as another one of the public network adapters.
If you have a network adapter that can transmit at multiple speeds and can specify a speed and duplex mode, manually specify a speed and duplex mode. With network adapters that can manually specify a speed and duplex mode, make sure that you hard set them to the same on all nodes and according to the manufacturer's specifications.
If you have the same speed and duplex settings, you can help make sure that you have reliable communication. This configuration provides sufficient bandwidth and reliable communication. Microsoft does not recommend that you use any type of fault-tolerant adapter or "Teaming" for the heartbeat. Verify that all others are disabled including such items as Network Monitor. Search results can then be filtered by OS compatibility, by vendor name, and by processor architecture.
To filter the search results by category, such as geographically dispersed cluster solutions, use the category filter. Note When you click any of the arrows next to the search boxes in the left navigation pane, the search boxes will simultaneously filter the results by the text that you typed in all the search boxes.
A separate mass-storage controller SCSI or Fibre that is independent of the controller that is used to boot the operating system. The shared disk. This is typically an external cabinet to which the mass-storage controller is attached that is connected to all nodes in the cluster. Note that adaptations of server clusters from OEMs may contain variations on these components, may not contain all of the components, or may contain more of the components that are listed.
Therefore, we recommend that you run the Microsoft Cluster Configuration Validation Wizard to determine any potential configuration problems before you configure a Windows server cluster or a Microsoft Windows Server server cluster. Press I Agree to accept these conditions. The Cluster Setup program in Windows displays the following agreement:. Your hardware configuration must be tested for compatibility with the Cluster service.
Windows Server does not display a dialog box that prompts for acceptance of the HCL or WSC agreement during the cluster configuration. The requirements for the Cluster service do state that an HCL cluster is required. If multiple clusters are attached to the same storage area network SAN device, extra steps are required. The nodes in the cluster must be certified with the particular SAN device.
If the cluster solution includes geographically dispersed cluster nodes, additional items such as network latency and shared disk support must be verified. See the following Microsoft Knowledge Base article for details:. There may be certain contractual limitations to which you must adhere.
