Understanding Cluster Validation Tests: System Configuration

  • Article

Applies To: Windows Server 2008

System configuration tests analyze the selected servers to determine whether they are properly configured for working together in a failover cluster. The system configuration tests include the following:

  • Validate Active Directory Configuration: This test validates that each tested server is in the same domain and organizational unit. It also validates that all tested servers are domain controllers or that all are member servers. To change the domain role of a server, use the Active Directory® Domain Services Installation Wizard.

  • Validate All Drivers Signed: This test validates that all tested servers contain only signed drivers. If an unsigned driver is detected, the test is not considered a failure, but a warning is issued.

    The purpose of signing drivers is to tell you whether the drivers on your system are original, unaltered files that either came with the operating system or were supplied by a vendor.

    You can get a list of system drivers and a list of unsigned drivers by running the corresponding inventory tasks. For more information, see Understanding Cluster Validation Tests: Inventory.

  • Validate Operating System Versions: This test validates that all tested servers have the same operating system version.

  • Validate Required Services: This test validates that the services that are required for failover clustering are running on each tested server and are configured to start automatically whenever the server is restarted.

  • Validate Same Processor Architecture: This test validates that all tested servers have the same architecture. A failover cluster is supported only if the systems in it are all 32-bit systems or all 64-bit systems.

  • Validate Service Pack Levels: This test validates that all tested servers have the same service packs. A failover cluster can run even if some servers have different service packs than others. However, servers with different service packs might behave differently from each other, with unexpected results. We recommend that all servers in the failover cluster have the same service packs.

  • Validate Software Update Levels: This test validates that all tested servers have the same software updates. A failover cluster can run even if some servers have different updates than others. However, servers with different software updates might behave differently from each other, with unexpected results. We recommend that all servers in the failover cluster have the same software update levels.
