SYMPTOMS
The swap file for the members of a Microsoft Windows NT cluster cannot be created on a shared disk.



CAUSE
Shared disks in a cluster configuration are owned by a single node at any given time. At that time, the other nodes in the cluster are prevented from gaining access to the shared disks.

Although the nodes in a cluster work together, each node is still a separate entity with its own requirements. One of these requirements is that each node must be a separate entity capable of running Windows NT, Enterprise Edition, or Windows 2000 on its own. Therefore, if one node should stop working, the other nodes can continue to function. Among the items that each computer in a cluster requires is physical memory and a swap file that acts as an extension of that memory.

As a result of this design, the computers never share a swap file and the swap file is then never a single point of failure that could affect all nodes in the cluster.



STATUS
This behavior is by design.
