CIM_SpareGroup class
The CIM_SpareGroup class is derived from the CIM_RedundancyGroup class and indicates that one or more of the aggregated elements can be spared. Spares are defined using the CIM_ActsAsSpare association. An example of a spare is the use of redundant NICs in a computer system, where one NIC is primary and the other is spare. The primary NIC would be a member of the spare group, associated using the CIM_RedundancyComponent class, and the other NIC would be associated using the CIM_ActsAsSpare relationship.
Important
The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of its inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties
The CIM_SpareGroup class has these properties.
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64), DisplayName ("Caption")
A short textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
CreationClassName
-
Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified.
This property is inherited from CIM_RedundancyGroup.
-
Description
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Description")
A textual description of the object.
This property is inherited from CIM_ManagedSystemElement.
-
-
InstallDate
-
-
Data type: datetime
-
Access type: Read-only
-
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5"), DisplayName ("Install Date")
Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.
This property is inherited from CIM_ManagedSystemElement.
-
-
Name
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: DisplayName ("Name")
Label by which the object is known. When subclassed, this property can be overridden to be a key property.
This property is inherited from CIM_ManagedSystemElement.
-
-
RedundancyStatus
-
-
Data type: uint16
-
Access type: Read-only
Information about the state of the redundancy group.
This property is inherited from CIM_RedundancyGroup.
-
-
Unknown (0)
-
Unknown.
-
Other (1)
-
Other.
-
Fully Redundant (2)
-
All of the configured redundancy is available.
-
Degraded Redundancy (3)
-
Reduced amount of redundancy is available due to some failures.
-
Redundancy Lost (4)
-
Redundancy is unavailable due to a sufficient number of failures. The next failure will cause overall failure.
Status
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (10), DisplayName ("Status")
String that indicates the current status of the object. Operational and non-operational status can be defined. Operational status can include "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).
Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.
This property is inherited from CIM_ManagedSystemElement.
Values include the following:
OK ("OK")
Error ("Error")
Degraded ("Degraded")
Unknown ("Unknown")
Pred Fail ("Pred Fail")
Starting ("Starting")
Stopping ("Stopping")
Service ("Service")
Stressed ("Stressed")
NonRecover ("NonRecover")
No Contact ("No Contact")
Lost Comm ("Lost Comm")
Remarks
The CIM_SpareGroup class is derived from CIM_RedundancyGroup.
WMI does not implement this class.
