Class CIM_LogicalDiskBasedOnPartition


  extends CIM_LogicalDiskBasedOnExtent (Association)
LogicalDisks can be BasedOn a DiskPartition. For example, a personal computer's C: drive may be located on a Partition on local PhysicalMedia. In this association of LogicalDisks to Partitions, note that the cardinality of the Antecedent, Disk Partition, is Max (1). This dictates that a LogicalDisk can not span more than one Partition. However, there are cases where this is true. When it occurs, the LogicalDisk is really based on some kind of RAID configuration (for example, a mirror or stripe set). In these scenarios, the LogicalDisk is more correctly BasedOn a StorageVolume. To prevent incorrectly using the LogicalDiskBasedOnPartition association, the Max (1) qualifier was put on the Antecedent reference to the DiskPartition.

EndingAddressuint64
DescriptionstringEndingAddress indicates where in lower level storage, the higher level Extent ends. This property is useful when mapping non-contiguous Extents into a higher level grouping.None TRANSLATABLE= true
OrderIndexuint16
DescriptionstringIf there is an order to the BasedOn associations that describe how a higher level StorageExtent is assembled, the OrderIndex property indicates this. When an order exists, the instances of BasedOn with the same Dependent value (i.e., the same higher level Extent) should place unique values in the OrderIndex property. The lowest value implies the first member of the collection of lower level Extents, and increasing values imply successive members of the collection. If there is no ordered relationship, a value of zero should be specified. An example of the use of this property is to define a RAID-0 striped array of 3 disks. The resultant RAID array is a StorageExtent that is dependent on (BasedOn) the StorageExtents that describe each of the 3 disks. The OrderIndex of each BasedOn association from the disk Extents to the RAID array could be specified as 1, 2 and 3 to indicate the order in which the disk Extents are used to access the RAID data.None TRANSLATABLE= true
StartingAddressuint64
DescriptionstringStartingAddress indicates where in lower level storage, the higher level Extent begins.None TRANSLATABLE= true
