SYMPTOMS
When you try to run a program on a Microsoft Windows Server 2003 cluster-based computer, the program calls the ClusterResourceControl function. The ClusterResourceControl function uses the CLUSCTL_RESOURCE_STORAGE_GET_DISK_INFO control code. In this scenario, the program may run slowly.



CAUSE
This issue occurs if the following conditions are true:
 * The CLUSCTL_RESOURCE_STORAGE_GET_DISK_INFO control code queries a disk on one node.
 * At least one disk is present on a second node.

When there are several disks on several nodes, the program spends lots of time querying between the disks.
