Migrate a multinode cluster to a single-node configuration

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To migrate a multinode cluster to a single-node configuration

If your multinode cluster has been upgraded from Windows 2000 or Windows NT 4.0, open Command Prompt, and type the following to create the Local Quorum resource type:

cluster restype "local quorum" /create /dll:clusres.dll /type:"local quorum"

If your multinode cluster is not an upgraded cluster, skip this step.
Open Cluster Administrator.
Create a Local Quorum resource on the node you want to configure as the single-node cluster.

For more information on creating a new resource, see "To create a new resource" in Related Topics.

For more information on the Local Quorum resource type, see "Local Quorum resource type" in Related Topics.
Remove all nodes from the cluster except the node you want to configure as the single-node cluster.

For more information on removing a node, see "To evict a node from the cluster" in Related Topics.
Verify that the single node now owns all resource groups by clicking on Groups in the console tree and reviewing the Owner column in the details pane.
Change the quorum resource to use the Local Quorum resource.

In the console tree, click the cluster name. On the File menu, click Properties. On the Quorum tab, click Quorum resource, and then select Local Quorum.
Select the appropriate partition.
Select the appropriate directory (root path). By default, the cluster database for a single-node cluster is stored at %systemroot%\Cluster\MSCS.

Important

If the quorum resource becomes corrupted, you cannot move it until it is repaired. For more information, see "Node-to-node connectivity problems" in Related Topics.

Notes

To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
To open Cluster Administrator, click Start, click Control Panel, double-click Administrative Tools, and then double-click Cluster Administrator.
Of the default resource types, only the Physical Disk, Local Quorum, or Majority Node Set resource can be a quorum resource. However, third party vendors can supply other storage class resource types that are quorum capable.
Cluster disks on a shared bus must be partitioned as master boot record (MBR) and not as GUID partition table (GPT) disks.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
