Incorrect TimeOutValue Setting in the Registry
When you run the Cluster Configuration wizard on a cluster solution running Windows
Server 2003, the wizard modifies the following registry value:
HKLM\System\CurrentControlSet\Services\Disk\TimeOutValue
The disk TimeOutValue setting is the timeout value set by Windows for storage system I/O
operations. The Dell | EMC Fibre Channel storage environment requires 60 seconds for
I/O operations. When you run the Cluster Configuration wizard, the wizard sets the
TimeOutValue setting to 20 seconds, which may not be sufficient for complex I/O
operations. Consequently, storage system I/O operations may continually time out.
Microsoft has confirmed a problem with the wizard and has implemented Quick Fix
Executable (QFE) file KB818877 to resolve this issue. See Microsoft Knowledge Base article
KB818877 on the Microsoft website at www.microsoft.com for more information. To resolve
