Microsoft releases sample utilities from the Windows 2000 Resource kits. Cluster Verification Utility is available for free download. It is included in the Windows 2000 Server Resource Kit only. This tool verifies that a two-node cluster is set up properly. It performs two tests:

• Configuration Verification: verify that the two cluster nodes can communicate with each other, and that both have access to the same shared SCSI drive or drives.
• Shared SCSI Drive Diagnostic Verification: tests a shared SCSI bus for functionality as required by the Cluster service systems.
  This test is should not be run on a cluster in production. The test destroys data on all disks on the shared bus.

There are a fair number of Resource kit samples available for download. Check Microsoft's Sample Tools for the list of current tools available for download.

A must for support and installations personnel as well as technical savvy users. 1800 pages with a wealth of information on the CD.
