This disk is reporting an error

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Win32_DiskDrive Microsoft Windows® Management Instrumentation (WMI) class to determine the value for the Status key for each disk. If the Exchange Server Analyzer determines that the value of the Status key for any disk does not equal OK, an error is displayed.

The Status key provides the current status of the disk object. Various operational and non-operational statuses can be defined. Operational statuses include:

  • OK

  • Degraded

  • Pred Fail (an element, such as a SMART-enabled hard drive, may be functioning correctly but predicting a failure in the near future).

  • Non-operational statuses include:

  • Error

  • Starting

  • Stopping

  • Service (this can apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work).

The Status key is inherited from the CIM_ManagedSystemElement WMI class, which includes the following values:

  • OK

  • Error

  • Degraded

  • Unknown

  • Pred Fail

  • Starting

  • Stopping

  • Service

  • Stressed

  • NonRecover

  • No Contact

  • Lost Comm

Generally, Microsoft does not provide documentation about troubleshooting disk failures for specific hardware vendors.

  1. Verify all disk and cable connections, wait 10 minutes, and then check the value for Status.

  2. If the value returned is not a maintenance mode value (for example, the value does not equal Service), you should follow the disk troubleshooting steps recommended by your hard disk manufacturer. In some cases, your hard disk manufacturer may have troubleshooting software that you can install to analyze the problem.
