Class CIM_LogicalDisk
extends CIM_StorageExtent

A LogicalDisk is a presentation of a contiguous range of logical blocks that is identifiable by applications such as filesystems via the Name field. (DeviceID (key) may use the same name or some other unique text such as a UUID.) For example in a Windows environment, the Name field may contain a drive letter. In a Unix environment, it may contain the access path (for example, '/dev/...'); and in a NetWare environment, may contain the volume name. LogicalDisks are typically built on a DiskPartition or other LogicalDisks (for instance, those exposed by a software volume manager). However, it can be based on other StorageExtents, like CIM_Memory, in the case of a RAM disk. LogicalDisks SHOULD set the 'Exported' value in ExtentStatus[] if they are intended for application use.
