Class CIM_LogicalDisk
extends CIM_StorageExtent

A LogicalDisk is a presentation of a contiguous range of logical blocks that is identifiable by a FileSystem via the Disk's DeviceId (key) field. For example in a Windows environment, the DeviceID field would contain a drive letter. In a Unix environment, it would contain the access path; and in a NetWare environment, DeviceID would contain the volume name. LogicalDisks are typically built on a DiskPartition or StorageVolume (for example, exposed by a software volume manager) using the LogicalDiskBasedOnPartition or LogicalDiskBasedOnVolume associations. However, it can be based on other StorageExtents, like CIM_Memory, in the case of a RAM disk. The latter is described using the LogicalDiskBasedOnExtent relationship. (Indeed, the BasedOnExtent association is the superclass for the BasedOnPartition and BasedOnVolume relationships.)
