Physical disk status is not OK

The information in this article applies to:

  • Visual Studio Team Foundation Server 2010

  • Windows Server 2003 and Windows Server 2008 

  • Application-tier server

  • Data-tier server

  • Health check

The Best Practices Analyzer tool for Team Foundation Server queries a Windows Management Instrumentation (WMI) class (Win32_DiskDrive) to determine the value of the Status key for each physical disk.

An error appears if the value of the Status key for any disk does not equal OK. The Status key provides the current status of the disk object. Various operational and non-operational statuses can be defined.

The following statuses are considered operational:

  • OK

  • Degraded

  • Pred Fail (An element, such as a SMART-enabled hard disk, might be functioning correctly, but a failure is predicted soon.)

The following statuses are considered non-operational:

  • Error

  • Starting

  • Stopping

  • Service (This status 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. This class 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 how to troubleshoot disk failures for specific hardware vendors.

To resolve this issue, troubleshoot the disk problem reported in the error.

To troubleshoot a disk problem

  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), follow the troubleshooting steps that your hard disk manufacturer recommends.

    In some cases, your hard disk manufacturer might provide troubleshooting software that you can install to analyze the problem.

For generic storage information that relates to Windows Server 2003, see "Windows Server 2003 Storage Services" in the Windows Server 2003 TechCenter on the Microsoft Web site.
