CIM_ExtraCapacityGroup class

The CIM_ExtraCapacityGroup class is derived from a redundancy group that indicates the aggregated elements have more capacity or capability than is needed. An example of this type of redundancy is the installation of N+1 power supplies or fans in a system.

[!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 inherited properties. Properties are listed in alphabetic order, not MOF order.

Members

The CIM_ExtraCapacityGroup class has these types of members:

Properties

The CIM_ExtraCapacityGroup 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

Data type: string

Access type: Read-only

Qualifiers: Key, MaxLen (256)

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.

MinNumberNeeded

Data type: uint32

Access type: Read-only

Smallest number of elements that must be operational to have redundancy. For example, in an N+1 redundancy relationship, this property should be set equal to N.

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_ExtraCapacityGroup class is derived from CIM_RedundancyGroup.

WMI does not implement this class.
