Msvm_DisketteController class

Represents the floppy controller in the virtual machine (VM). The floppy controller is fixed, therefore there is no resource pool associated with it.

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

A user-friendly name for the object. This property is inherited from CIM_ManagedElement and it is set to "Diskette Controller" by default.

EnabledDefault
Data type: uint16
Access type: Read-only

An administrator's default or startup configuration for the enabled state of an element. This property is inherited from CIM_EnabledLogicalElement and it is always set to 2 (Enabled).

EnabledState
Data type: uint16
Access type: Read-only

The enabled and disabled states of an element. It can also indicate the transitions between these requested states. This property is inherited from CIM_EnabledLogicalElement and it is always set to 5 (Not Applicable).

ErrorCleared
Data type: boolean
Access type: Read-only

This property is inherited from CIM_LogicalDevice but it is not used.

ErrorDescription
Data type: string
Access type: Read-only

This property is inherited from CIM_LogicalDevice but it is not used.

HealthState
Data type: uint16
Access type: Read-only

The current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely non-functional. This property is inherited from CIM_ManagedSystemElement and it is always set to 5.

IdentifyingDescriptions
Data type: string array
Access type: Read-only

This property is inherited from CIM_LogicalDevice and it is set to NULL.

InstallDate
Data type: datetime
Access type: Read-only

The date and time the virtual machine configuration was created. This property is inherited from CIM_ManagedSystemElement.

LastErrorCode
Data type: uint32
Access type: Read-only

This property is inherited from CIM_LogicalDevice but it is not used.

LocationIndicator
Data type: uint16
Access type: Read-only

This property is inherited from CIM_LogicalDevice and it is set to 4 (Not Supported).

MaxNumberControlled
Data type: uint32
Access type: Read-only

The maximum number of directly addressable entities that are supported by this controller. A value of 0 should be used if the number is unknown or unlimited. The protocol used by the controller to access controlled devices. This property is inherited from CIM_Controller and it is set to 1.

Data type: uint64
Access type: Read-only

This property is inherited from CIM_LogicalDevice but it is not used.

Name
Data type: string
Access type: Read-only

The label by which the object is known. This property is inherited from CIM_ManagedSystemElement and it is the same as the ElementName property.

OperationalStatus
Data type: uint16 array

This property is provided to compare the last requested and current enabled or disabled states. A particular instance of an enabled logical element might not support RequestedStateChange. If this occurs, the value 12 (Not Applicable) is used. This property is inherited from CIM_EnabledLogicalElement and it is always set to 12 (Not Applicable).

Status
Data type: string
Access type: Read-only

This property is inherited from CIM_ManagedSystemElement but it is not used.

StatusDescriptions
Data type: string array

Strings that describes the various OperationalStatus array values. This property is inherited from CIM_ManagedSystemElement and each array element is always set to "OK".

StatusInfo
Data type: uint16
Access type: Read-only

This property is inherited from CIM_LogicalDevice but it is not used.

SystemCreationClassName

SystemName
Data type: string
Access type: Read-only

The unique identifier for the scoping virtual system. This property is inherited from CIM_LogicalDevice.

TimeOfLastReset
Data type: datetime
Access type: Read-only

The last time the virtual computer system was powered on. This property is inherited from CIM_Controller.

TimeOfLastStateChange
Data type: datetime
Access type: Read-only
