44 // Description: The Device Model extends the management concepts that
45 // are related to LogicalDevices. This file describes
46 // the modeling of storage hierarchies (extents,
47 // volumes, partitions, etc.).
48 //
49 // The object classes below are listed in an order that
50 // avoids forward references. Required objects, defined
51 // by other working groups, are omitted.
52 // ==================================================================
53 // Change Log for v2.7 Final
54 // CR970 - Removal of the Experimental qualifier
55 // - Remove several properties from StorageVolume and make them
56 // Experimental in 2.8
57 //
58 // Change Log for v2.7
59 // CR722 - Add ProtectedExtentBasedOn, CompositeExtent, and
60 // CompositeExtentBasedOn
61 // CR882 - Deprecate Snapshot and SnapshotOfExtent. Therefore moved
62 // definitions to SccExtents.mof
63 // CR884 - Move RAID centric properties from StorageExtent to
