Msvm_IDEController class

Represents an IDE controller. This class can support up to four drives attached to the controller. The IDE controller is fixed in the virtual machine and therefore does not have a resource pool associated with it.

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

Methods

The Msvm_IDEController class has these methods.

Properties

The Msvm_IDEController class has these properties.

AdditionalAvailability

Data type: uint16 array

Access type: Read-only

Any additional availability and status of the device. This property is inherited from CIM_LogicalDevice.

Availability

Data type: uint16

The primary availability and status of the device. This property is inherited from CIM_LogicalDevice.

AvailableRequestedStates

Data type: uint16 array

Access type: Read-only

Indicates the possible values for the RequestedState parameter of the RequestStateChange method used to initiate a state change. The values listed will be a subset of the values contained in the RequestedStatesSupported property of the associated instance of CIM_EnabledLogicalElementCapabilities, where the values selected are a function of the current state of the CIM_EnabledLogicalElement object. This property can be non-Null if an implementation is able to advertise the set of possible values as a function of the current state. This property will be Null if an implementation is unable to determine the set of possible values as a function of the current state.

This property is inherited from CIM_EnabledLogicalElement.

Caption

Indicates whether the error reported in LastErrorCode is now cleared. This property is inherited from CIM_LogicalDevice, but it is not used.

ErrorDescription

Data type: string

Access type: Read-only

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 nonfunctional. This property is inherited from CIM_ManagedSystemElement.

IdentifyingDescriptions

Data type: string array

Access type: Read-only

An array of free-form strings that provide explanations and details behind the entries in the OtherIdentifyingInfo property array. This property is inherited from CIM_LogicalDevice, but it is not used.

InstallDate

Data type: datetime
