CIM_LogicalDisk class

Represents a contiguous range of logical blocks that is identifiable by a file system through the disk's DeviceID (key) field. For example, in a Windows environment, the DeviceID field contains a drive letter; in a UNIX environment, it contains the access path; and in a NetWare environment, it contains the volume name.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Note

The OperationalStatus property replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, we strongly recommend that providers or instrumentation provide both the Status and OperationalStatus properties.

Indicates that the implementation cannot report on the OperationalStatus property at this time.

Other (1)

Indicates an undefined state.

OK (2)

Completed (17)

Indicates that the job has completed its operation. This value should be combined with either OK, Error, or Degraded to indicate to a client whether the complete operation Completed with OK and passed, or completed with Error and failed, or completed with Degraded and finished the operation, but did not complete OK or did not report an error.
