MSFT_StorageFaultDomain class

Common base class for all storage fault domain objects.

The following syntax is simplified from MOF code and includes all inherited properties.

Syntax

class MSFT_StorageFaultDomain : MSFT_StorageObject
{
  String Manufacturer;
  String Model;
  String SerialNumber;
  String PhysicalLocation;
  UInt16 HealthStatus;
  UInt16 OperationalStatus[];
};

Members

The MSFT_StorageFaultDomain class has these types of members:

• Properties

Properties

The MSFT_StorageFaultDomain class has these properties.

HealthStatus

Data type: UInt16

Access type: Read-only

The health status of the object.

Value	Meaning
Healthy 0	The object is in a good state. There has been no reported read or write packet loss.
Warning 1	The object may be failing some read requests, but there have been no reported write failures.
Unhealthy 2	The object is failing read and write requests, or is no longer responding to any commands.
Unknown 5	The health status is unknown.

Manufacturer

Data type: String

Access type: Read-only

The name of the company responsible for the hardware backing the fault domain object. For MSFT_PhysicalDisk it must match the disk's SCSI inquiry data.

Model

Data type: String

Access type: Read-only

Represents the model number of the hardware. For MSFT_PhysicalDisk it must match the disk's SCSI inquiry data.

OperationalStatus

Data type: UInt16 array

Access type: Read-only

An array of values that specify the operational status of the object.

Value	Meaning
Unknown 0	The operational status of the object is unknown.
Other 1	A vendor-specific operational status has been specified.
OK 2	The object is responding to commands and is in a normal operating state.
Degraded 3	The object is responding to commands but is not running in an optimal operating state.
Stressed 4	The object is functioning but needs attention. For example, it might be overloaded or overheated.
Predictive Failure 5	The object is functioning nominally, but a failure in the near future is predicted.
Error 6	An error has occurred.
Non-Recoverable Error 7	A nonrecoverable error has occurred.
Starting 8	The object is in the process of starting.
Stopping 9	The object is in the process of stopping.
Stopped 10	The object was stopped or shut down in a clean and orderly fashion.
In Service 11	The object is being configured, maintained, cleaned, or otherwise administered.
No Contact 12	The storage provider has knowledge of the object but has never been able to establish communication with it.
Lost Communication 13	The object is known to exist and has been contacted successfully in the past but is currently unreachable.
Aborted 14	Similar to Stopped, except that the object stopped abruptly and may require configuration or maintenance.
Dormant 15	The object is reachable, but it is inactive.
Supporting Entity in Error 16	This status value does not necessarily indicate trouble with the object, but it does indicate that another device or connection that the object depends on may need attention.
Completed 17	The object has completed an operation. This status value should be combined with OK, Error, or Degraded, depending on the outcome of the operation
Power Mode 18	This value is reserved for system use.
Relocating 19	The object is in the process of relocating.
Microsoft Reserved ..	This value is reserved for system use.
Failed Media 0xD004
Split 0xD005
Stale Metadata 0xD006
IO Error 0xD007
Unrecognized Metadata 0xD008
Microsoft Reserved 0xD009..	This value is reserved for system use.

PhysicalLocation

Data type: String

Access type: Read-only

A free-form string indicating where the hardware is located.

SerialNumber

Data type: String

Access type: Read-only

Represents the serial number of the hardware. For MSFT_PhysicalDisk it must match the disk's SCSI inquiry data.

Requirements

Requirement	Value
Minimum supported client	Windows 10 [desktop apps only]
Minimum supported server	Windows Server 2016 [desktop apps only]
