A hotfix is available that adds support for GUID partition table (GPT) volumes that are larger than 2 terabytes on a Windows Server 2003-based server cluster

A hotfix is now available to add support for GUID partition table (GPT) volumes that are larger than 2 terabytes on a Microsoft Windows Server 2003-based server cluster.

When you apply this hotfix on a Windows Server 2003-based server cluster, you can use GPT volumes that are larger than 2 terabytes.

Note You cannot use the Windows interface to change a master boot record disk into a GUID partition table disk after the cluster is installed. Instead, you must use the convert gpt Diskpart command. You may notice a new partition that has a size of 1,024 bytes on clustered GPT volumes. On GPT disks, cluster creates this small partition in the MSR to help with the arbitration process.

For more information about how to use Diskpart to convert a master boot record (MBR) disk to a GUID partition table disk, visit the following Microsoft Web page:

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.
