SYMPTOMS
Consider the following scenario:
 * You configure the NTFS file system volume mount points as shared physical disk resources on a Microsoft Windows Server 2003-based server cluster that uses the Microsoft iSCSI Initiator service.
 * You use Cluster Administrator (CluAdmin.exe) to bring online the NTFS volume mount points that are configured as shared physical disk resources.

In this scenario, the following symptoms occur:
 * Cluster Administrator stops responding, and the cluster fails.
 * The individual cluster nodes stop responding or the cluster nodes stop functioning as a server cluster.
 * The physical disk resources do not come online, although the disk objects become available.

These symptoms occur during failover when one of the following conditions is true:
 * Many cluster mount point resources are in the same cluster group. For example, this problem has been observed when 30 or more cluster mount point resources are created in the same cluster group.
 * Several cluster groups have many physical disk resources

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
