PROPERTYSMS_REPORTCIMTYPEDESCRIPTION
AddressSizeUInt16An integer indicating the DMA channel address size in bits. Permissible values are 8, 16, 32 or 64 bits. If unknown, enter 0.
AvailabilityUInt16The Availability property indicates the availability of the DMA.
BurstModeBooleanIndicate whether the DMA channel supports burst mode
ByteModeUInt16Indicates whether DMA may execute in 'count by byte' mode (value=4) or not (value=3). Also, "Other" (1) and "Unknown" (2) may be defined.
CaptionStringThe Caption property is a short textual description (one-line string) of the object.
ChannelTimingUInt16DMA channel timing. For example, "Type A" (value =4) or "Type F" (6) could be specified.
CreationClassNameStringCreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
CSCreationClassNameStringThe scoping computer system's creation class name.
CSNameStringThe scoping computer system's name.
DescriptionStringThe Description property provides a textual description of the object.
DMAChannelUInt32A part of the object's key value, the DMA channel number.
InstallDateDateTimeThe InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.
MaxTransferSizeUInt32The maximum number of bytes that can be transferred by this DMA channel. If unknown, enter 0.
NameStringThe Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.
StatusStringThe Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.
TransferWidthsUInt16An array indicating all the transfer widths (in bits) supported by this DMA Channel. Permissible values are 8, 16, 32, 64 or 128 bits. If unknown, enter 0.
TypeCTimingUInt16Indicates whether C type (burst) timing is supported (value=5) or not (value=4). Also, "Other" (1), "Unknown" (2) and "ISA Compatible" (3) are defined.
WordModeUInt16Indicates whether DMA may execute in 'count by word' mode (value=4) or not (value=3). Also, "Other" (1) and "Unknown" (2) may be defined.
