|Description||string||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.
