MSFT_MTDisk class

The disk drive data object. Statistic data is calculated based on current interval seconds setting.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Members

The MSFT_MTDisk class has these types of members:

• Properties

Properties

The MSFT_MTDisk class has these properties.

ActiveTime

Data type: real32 array

Access type: Read-only

Gets a list of percentage of active time accessing to and from the disk drive.

AverageResponseTime

Data type: real32

Access type: Read-only

Gets the average response time during latest sampling interval on the disk drive, in milliseconds.

Capacity

Data type: uint64

Access type: Read-only

Gets the capacity of the disk drive.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

The Caption property is a short textual description (one- line string) of the object.

This property is inherited from CIM_ManagedElement.

CurrentIndex

Data type: uint16

Access type: Read-only

Gets the current data sample index. Increment at every data sample.

Description

Data type: string

Access type: Read-only

The Description property provides a textual description of the object.

This property is inherited from CIM_ManagedElement.

DiskNumber

Data type: uint32

Access type: Read-only

Gets the index number of storage disk device for the disk drive. It is not guaranteed to be persistent across boots.

ElementName

Data type: string

Access type: Read-only

Gets a user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of CIM_ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of CIM_LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.

This property is inherited from CIM_ManagedElement.

InstanceID

Data type: string

Access type: Read-only

InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: "OrgID:LocalID" Where OrgID and LocalID are separated by a colon (:), and where OrgID must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, OrgID must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between OrgID and LocalID. LocalID is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. If not set to null for DMTF-defined instances, the "preferred" algorithm must be used with the OrgID set to "CIM".

This property is inherited from CIM_ManagedElement.

IntervalSeconds

Data type: uint16

Access type: Read-only

Gets the current data collection interval in seconds.

Name

Data type: string

Access type: Read-only

Qualifiers: key

Gets the name of disk drive.

ReadTransferRate

Data type: real32 array

Access type: Read-only

Gets a list of historical statistics of average disk read transfer rate, in byte, per second, logging latest 60 samples at each interval defined in IntervalSeconds (second).

Volumes

Data type: MSFT_MTDiskVolume array

Access type: Read-only

Qualifiers: EmbeddedInstance ("MSFT_MTDiskVolume")

Gets an array of MSFT_MTDiskVolume objects containing disk volumes configured on the disk drive.

WriteTransferRate

Data type: real32 array

Access type: Read-only

Gets a list of historical statistics of average disk write transfer rate, in byte, per second, logging latest 60 samples at each interval defined in IntervalSeconds (second).
