How to Troubleshoot the Fault that the MSCS Cluster Fails to Use a Hard Disk Larger than 2 TB Mapped from the S2600?

Publication Date:  2012-07-20 Views:  37 Downloads:  0
Issue Description
On a deployment site, the MSCS cluster services are configured. A 5 TB disk space on the S2600 is to be provided to the MSCS cluster. However, after the disk is mapped to the cluster server, it is found that a hard disk larger than 2 TB fails to be used in the GPT mode.  
Alarm Information
None
Handling Process
Step 1  Enable the support to the GPT disks on the cluster server that runs the Windows Server 2003.
Step 2  Install the Windows patch (ID: 919117). The Web site link is http://support.microsoft.com/kb/919117.
Step 3  Initialize the 5 TB hard disks mapped from the S2600 to a GPT disk.
Step 4  Map the disk to the NSCS cluster server.
 
Root Cause
The MSCS cluster server does not support the GPT disks. Therefore, the programs or services relevant to the disks are unavailable in the cluster.
Suggestions
To enable the support to the GPT disks in the MSCS cluster, upgrade the operating system to Windows 2003 SP1 or a later version, and install the Microsoft patch (ID: 919117).
