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.

Data type: uint64

Access type: Read-only

Qualifiers: Units ("MilliSeconds"), PUnit ("second * 10^-3")

The time it takes, in milliseconds, for the device to be able to read or write a media after the device starts loading. For example, for disk drives, this is the interval between a disk not spinning to the disk reporting that it is ready for read/write operations. For tape drives, this starts when media is inserted and ends when the drive reports that it is ready for an application. This is usually at the tape's beginning-of-tape (BOT) area.

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.

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.

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.

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.

TimeOfLastMount

Data type: datetime

Access type: Read-only

The most recent date and time when media was mounted on the device. This property is only used by devices that support removable media.

This property is inherited from CIM_MediaAccessDevice.

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.

TotalMountTime

Data type: uint64

Access type: Read-only

The time, in seconds, that media has been mounted for data transfer or to clean the device. If the device does not support removable media, this property should be set to zero.

This property is inherited from CIM_MediaAccessDevice.

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.

UncompressedDataRate

Data type: uint32

Access type: Read-only

Qualifiers: Units ("KiloBytes per Second"), PUnit ("byte / second * 10^3")

The sustained data transfer rate in kilobytes at which the device can read and write to a media. This is a sustained, raw data rate. Maximum rates or rates with compression should not be reported in this property.

This property is inherited from CIM_MediaAccessDevice.

UnitsDescription

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_MediaAccessDevice.MaxUnitsBeforeCleaning", "CIM_MediaAccessDevice.UnitsUsed")

Describes the unit type of the MaxUnitsBeforeCleaning and UnitsUsed properties.

This property is inherited from CIM_MediaAccessDevice.

UnitsUsed

Data type: uint64

Access type: Read-only

Qualifiers: Gauge, ModelCorrespondence ("CIM_MediaAccessDevice.UnitsDescription", "CIM_MediaAccessDevice.MaxUnitsBeforeCleaning")

The number of units used by the device. This property is used to determine when the device should be cleaned. UnitsDescription defines how the unit type.

This property is inherited from CIM_MediaAccessDevice.

UnloadTime

Data type: uint64

Access type: Read-only

Qualifiers: Units ("MilliSeconds"), PUnit ("second * 10^-3")

The time it takes, in milliseconds, for the device to transition from reading or writing media to unloading. For example, for disk drives, this is the interval between a disk spinning at nominal speeds and a disk not spinning. For tape drives, this is the time for a media to go from its BOT to being fully ejected and accessible to a picker element or human operator.

This property is inherited from CIM_MediaAccessDevice.
