TITLE: Upgrade Pegasus to Include the CIM 2.31 Schema in CVS

DESCRIPTION:

   [Version ( "2.19.0" ), 
    UMLPackagePath ( "CIM::Device::StorageServices" ), 
    Description ( 
       "A StoragePool is a conglomeration of storage capacity for the "
       "purpose of assignment and allocation based on service "
       "characteristics, such as location, available space or other "
       "criteria (for example, cost per megabyte or hardware "
       "ownership). A StoragePool is managed within the scope of a "
       "particular System. StoragePools may consist of component "
       "StoragePools or StorageExtents. StorageExtents that belong to "
       "the StoragePool have a Component relationship to the "
       "StoragePool. StorageExtents/StoragePools that are elements of "
       "a pool have their available space aggregated into the pool. "
       "StoragePools, StorageVolumes and LogicalDisks may be created "
       "from StoragePools. This is indicated by the "
       "AllocatedFromStoragePool association. StoragePool is scoped to "
       "a system by the HostedStoragePool association." )]

       Description ( 
          "Within the scope of the instantiating Namespace, "
          "InstanceID opaquely and uniquely identifies an instance "
          "of this class. In order to ensure uniqueness within the "
          "NameSpace, the value of InstanceID SHOULD be constructed "
          "using the following \'preferred\' algorithm: \n"
          "<OrgID>:<LocalID> \n"
          "Where <OrgID> and <LocalID> are separated by a colon "
          "\':\', and where <OrgID> MUST include a copyrighted, "
          "trademarked or otherwise unique name that is owned by "
          "the business entity creating/defining the InstanceID, or "
          "is a registered ID that is assigned to the business "
          "entity by a recognized global authority (This is similar "
          "to the <Schema Name>_<Class Name> structure of Schema "
          "class names.) In addition, to ensure uniqueness <OrgID> "
          "MUST NOT contain a colon (\':\'). When using this "
          "algorithm, the first colon to appear in InstanceID MUST "
          "appear between <OrgID> and <LocalID>. \n"
          "<LocalID> is chosen by the business entity and SHOULD "
          "not be re-used to identify different underlying "
          "(real-world) elements. If the above \'preferred\' "
          "algorithm is not used, the defining entity MUST assure "
          "that the resultant InstanceID is not re-used across any "
          "InstanceIDs produced by this or other providers for this "
          "instance\'s NameSpace. \n"
          "For DMTF defined instances, the \'preferred\' algorithm "
          "MUST be used with the <OrgID> set to \'CIM\'." )]
