CIM_LogicalDisk class

Article
05/31/2018

Represents a contiguous range of logical blocks that is identifiable by a file system through the disk's DeviceID (key) field. For example, in a Windows environment, the DeviceID field contains a drive letter; in a UNIX environment, it contains the access path; and in a NetWare environment, it contains the volume name.

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

This property is inherited from CIM_ManagedSystemElement.

InstanceID

Data type: string
Access type: Read-only

Uniquely and opaquely identifies an instance of this class within the scope of the containing namespace.

[!Important]

In order to ensure uniqueness within the namespace, the value of the InstanceID property should be constructed in the following pattern: OrgID:LocalID

OrgID must include a copyrighted, trademarked or otherwise unique name that is owned by the business entity that defines the InstanceID, or be a registered ID that is assigned by a recognized global authority. This pattern is similar to the structure of schema class names. In addition, to ensure uniqueness, the first colon in InstanceID must be between the OrgID andLocalID. Therefore the OrgID must not contain a colon (':').

LocalID is chosen by the business entity and should not be re-used to identify different underlying real-world elements.

If the above pattern is not used, the defining entity must assure that the resultant InstanceID value is not re-used across any InstanceID properties that are produced by this provider or other providers for this namespace.

For Distributed Management Task Force (DMTF) defined instances, the pattern must be used with the OrgID set to CIM.

This property is inherited from CIM_ManagedElement.

OperationalStatus

Data type: uint16 array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")

Contains indicators of the current status of the element. The first value of the OperationalStatus property should contain the primary status for the element.

Note

The OperationalStatus property replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, we strongly recommend that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status, because it is a single-valued property, should also provide the primary status of the element.

This property is inherited from CIM_ManagedSystemElement.

Indicates that the implementation cannot report on the OperationalStatus property at this time.

Other (1)

Indicates an undefined state.

OK (2)

Indicates that the element functions, but requires attention. Overload and overheated are examples of Stressed states.

Predictive Failure (5)

Indicates that an element functions nominally, but predicts a failure in the near future.

Indicates that the element is in process to be configured, maintained, cleaned, or otherwise administered.

No Contact (12)

Indicates that the monitoring system has information about this element, but has never been able to establish communications with it.

Lost Communication (13)

Indicates that the monitoring system has successfully contacted this element in the past, but it is currently unavailable.

Aborted (14)

Indicates that the job stopped in an unexpected way. The state and configuration of the job might require an update.

Dormant (15)

Indicates that the job is inactive.

Supporting Entity in Error (16)

Indicates that an element on which this job depends is in error. This element might be OK but cannot function because of the state of a dependent element. An example is a network service or endpoint that cannot function due to lower-layer networking problems.

Completed (17)

Indicates that the job has completed its operation. This value should be combined with either OK, Error, or Degraded to indicate to a client whether the complete operation Completed with OK and passed, or completed with Error and failed, or completed with Degraded and finished the operation, but did not complete OK or did not report an error.

Indicates that the element might be completing commands, but that it queues any new requests.

Quiesce (9)

Indicates that the element is enabled but is in a restricted mode.

Reboot (10)

Indicates a request to shut down and then change to an Enabled state.

Reset (11)

Indicates a request to change to a Disabled state and then change to an Enabled state.

Not Applicable (12)

Indicates that this instance does not support the RequestedState property.

SequentialAccess

Data type: boolean
Access type: Read-only

true if storage is sequentially accessed by a CIM_MediaAccessDevice object; otherwise, false.

This property is inherited from CIM_StorageExtent.

Status

Data type: string
Access type: Read-only
Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

Indicates the primary status of the object.

Note

This property is deprecated. It is replaced by the OperationalStatus property. If you choose to use the Status property for backward compatibility, it should be secondary to the OperationalStatus property.

This property is inherited from CIM_ManagedSystemElement.

The possible values are.

("OK")

("Error")

("Degraded")

("Unknown")

("Pred Fail")

("Starting")

("Stopping")

("Service")

("Stressed")

("NonRecover")

("No Contact")

("Lost Comm")

("Stopped")

StatusDescriptions

Data type: string array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.OperationalStatus")

Indicates descriptions of the corresponding values in the OperationalStatus array. For example, if an element in the OperationalStatus property contains the value Stopping, then the element at the same array index in this property might contain an explanation as to why an object is being stopped.

This property is inherited from CIM_ManagedSystemElement.

StatusInfo

Data type: uint16
Access type: Read-only
Qualifiers: Deprecated ("CIM_EnabledLogicalElement.EnabledState"), MappingStrings ("MIF.DMTF|Operational State|006.4")

Deprecated description: Indicates whether the logical device is enabled or in a related state.

This property is deprecated. Instead we recommend that you use the CIM_PowerManagementCapabilities class.

This property is inherited from CIM_LogicalDevice.

The possible values are:

Unknown (2)

Enabled (3)

Disabled (4)

Not Applicable (5)

SystemCreationClassName

Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256), Propagated ("CIM_System.CreationClassName")

The class name used to create an instance of the system that contains the logical device. SystemCreationClassName is combined with other key properties of this class to uniquely identify instances of this class and its subclasses.

This property is inherited from CIM_LogicalDevice.

SystemName

Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256), Propagated ("CIM_System.Name")

The name of the system that contains the logical device.

This property is inherited from CIM_LogicalDevice.

TimeOfLastStateChange

Data type: datetime
Access type: Read-only

Indicates when the element last changed state. If the state of the element has not changed and this property is populated, then it must be set to a zero interval value. If a state change was requested, but was rejected or is not yet processed, the property must not be updated.

This property is inherited from CIM_EnabledLogicalElement.

TotalPowerOnHours

Data type: uint64
Access type: Read-only
Qualifiers: Units ("Hours"), Counter

The total number of hours the logical device has been powered.

This property is inherited from CIM_LogicalDevice.

TransitioningToState

Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.RequestStateChange", "CIM_EnabledLogicalElement.RequestedState", "CIM_EnabledLogicalElement.EnabledState")

Indicates the target state to which the instance is changing.

A value of No Change indicates that no transition is in progress. A value of Not Applicable indicates that the implementation does not report ongoing transitions.

This property is inherited from CIM_EnabledLogicalElement.

The possible values are.
