SYMPTOMS

When you try to install or bring online a 32-bit resource on a 64-bit server cluster, you may experience unexpected results. Specifically, the resource may not come online, or it may constantly attempt to failover to another node.

CAUSE

This behavior occurs because 64-bit processes cannot directly load 32-bit DLLs. Therefore the Resource Monitor (64-bit process) cannot directly load a 32-bit Cluster Resource DLL. Typically Cluster Resource DLLs are directly loaded in the process space of the Resource Monitor, and this means that only 64-bit DLLs can be loaded under the 64-bit Resource Monitor process.

RESOLUTION

Contact the vendor that created the program or cluster resource to obtain an updated 64-bit version. Microsoft Exchange 5.5, Microsoft Exchange 2000, Microsoft SQL 7.0 and Microsoft SQL 2000 use 32-bit cluster resources and are not supported on 64-bit server clusters.

MORE INFORMATION

To help determine if a cluster resource is 32-bit or 64-bit, use the VFI utility that is included in the Windows Server 2003 Resource Kit.
