Cluster is formed by using a local quorum resource after a cluster setup failure in Windows Server 2003

View products that this article applies to.

SYMPTOMS

If you set up a new server cluster in Windows Server 2003, and the system boot disk, the pagefile disks, and the cluster disks are on the same storage area network (SAN) fabric, a setup failure may occur. In this scenario, the ClusSvc registry subkey may be re-created. Therefore, the ManageDisksOnSystemBuses registry entry is removed, and the server cluster is formed by using a local quorum resource.

In Windows Server 2003, you can use the ManageDisksOnSystemBuses DWORD registry entry to enable the system boot disk, the pagefile disks, and the cluster disks to be on the same bus.

Note After the cluster is installed and configured, an error message that resembles the following may be logged in the %Windir%\Cluster\Cluster.log file:

INFO Physical Disk <Disk Q:>: [DiskArb]- DisksArbitrate -.
INFO Physical Disk <Disk Q:>: [DiskArb] DisksOpenResourceFileHandle: Attaching to disk with signature eb14995a

WARN [MM] MMLeave is called when rgp=NULL.
ERR [CS] Service Stopped. exit code = 5086 Where error 5086 = The quorum disk could not be located by the cluster service.

The errors are logged when disks are enumerated after a group is moved or a node is restarted. If the Quorum disk is on the same bus as the system disk, this problem may cause the Cluster Service to stop.

Note The disk signature that is logged as a problem is not changed. There is no problem with the disk signature.

RESOLUTION

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows

To resolve this problem, install the updated Microsoft Storport storage driver, version 5.2.3790.217, and then modify the registry to add and to enable the ManageDisksOnSystemBuses registry entry in the ClusSvc registry subkey. To do this, follow these steps.

Note These steps must be performed on each node after the node is added to the cluster.

Install version 5.2.3790.217 of the Storport storage driver. This driver is described in the following article:
883646 (http://support.microsoft.com/kb/883646/ ) The updated Storport storage driver, version 5.2.3790.217, fixes a range of Storport-related problems in Windows Server 2003
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ClusSvc\Parameters
Note If you have Service Pack 1 or a later service pack installed, locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Clusdisk\Parameters ManageDisksOnSystemBuses
On the Edit menu, point to New, and then click DWORD Value.
Type ManageDisksOnSystemBuses for the name of the DWORD, and then press ENTER.
Right-click ManageDisksOnSystemBuses, and then click Modify.
In the Value data box, enter a hexadecimal value of 1, and then click OK.
Exit Registry Editor.

After you install the updated Storport storage driver and modify the registry, follow these steps to complete the procedure:

After the first node is running the Cluster service, create new disk resources in Cluster Administrator, and then bring them online.
After all the disks are online, use the procedure in the following article to move the quorum resource from a local disk to a disk resource that appears in the Cluster Administrator tool:

280353 (http://support.microsoft.com/kb/280353/ ) How to change the quorum disk designation
Add the remaining nodes to the cluster, and then install the updated Storport storage driver. Add and enable the ManageDisksOnSystemBuses registry entry in the ClusSvc registry subkey for each node after it is added.
Fail over all the resource groups to each cluster node.
