// RedundancyGroup
// ===================================================================
[Version ("2.7.0"), Description (
    "A class derived from LogicalElement that is a special "
    "collection of ManagedSystemElements. This collection indicates "
    "that the aggregated components together provide redundancy. "
    "All elements aggregated in a RedundancyGroup should be "
    "instantiations of the same object class.") ] 
class CIM_RedundancyGroup : CIM_LogicalElement {

    [Key, MaxLen (256), Description (
        "CreationClassName indicates the name of the class or "
        "the subclass used in the creation of an instance. When "
        "used with the other key properties of this class, this "
        "property allows all instances of this class and its "
        "subclasses to be uniquely identified.") ]
    string CreationClassName;

    [Override("Name"), Key, MaxLen (256), Description (
        "The RedundancyGroup Name serves as the key for the "
        "Group's instance in an enterprise environment.") ]
    string Name;

    [Description (
        "RedundancyStatus provides information on the state of the "
        "RedundancyGroup. \"Fully Redundant\" (value=2) means that "
        "all of the configured redundancy is still available; "
        "\"Degraded Redundancy\" (3) means that some failures have "
        "been experienced but some reduced amount of redundancy is "
        "still available; \"Redundancy Lost\" (4) means that a "
        "sufficient number of failures have been experienced such "
        "that no redundancy is available and the next failure "
        "experienced will cause overall failure. Also, the values, "
        "\"Other\" (1) and \"Unknown\" (0), are defined."),
        ValueMap {"0", "1", "2", "3", "4"}, 
        Values {"Unknown", "Other", "Fully Redundant", 
           "Degraded Redundancy", "Redundancy Lost"} ]
   uint16 RedundancyStatus;
};


// ===================================================================
// RedundancyComponent
// ===================================================================
[Association, Aggregation, Version ("2.7.1"), Description (
    "A RedundancyGroup aggregates Managed System Elements and "
    "indicates that these elements, taken together, provide "
    "redundancy. All elements aggregated in a RedundancyGroup "
    "should be instantiations of the same object class.") ] 
class CIM_RedundancyComponent : CIM_Component {

    [Override ("GroupComponent"), Aggregate, Description (

// ===================================================================
// SpareGroup
// ===================================================================
[Version ("2.6.0"), Description (
    "A class derived from RedundancyGroup indicating that one or "
    "more of the aggregated elements can be spared. (The actual "
    "Spares are defined using the ActsAsSpare association.) An "
    "example is the use of redundant NICs in a ComputerSystem - "
    "where one NIC is primary and the other is Spare. The 'primary' "
    "NIC would be a member of the SpareGroup (associated using the "
    "RedundancyComponent class) and the 'other' NIC would be "
    "associated using the ActsAsSpare relationship.") ] 
class CIM_SpareGroup : CIM_RedundancyGroup {

    [Description (
        "This method is forces a failover from one ManagedSystem"
        "Element to another.  There are two parameters to the Failover "
        "method, FailoverFrom and FailoverTo. The FailoverFrom "
        "parameter is a reference to the primary ManagedSystemElement "
        "that will become inactive after the method. This Element "
        "should be associated with the SpareGroup through the "
        "RedundancyComponent relationship. The FailoverTo parameter "
        "is a reference to the ManagedSystemElement that will take "
        "over for the primary. This Element should be associated with "
        "the SpareGroup through the ActsAsSpare association. Once the "
        "failover has occurred, the SpareGroup and the Redundancy"
        "Component and ActsAsSpare associations will be updated with "
        "current status.  For example, the ActsAsSpare association "
        "that contained the FailoverTo Element will be deleted and a "
        "new RedundancyComponent association instantiated in its "
        "place. The method should return 0 if successful, 1 if the "
        "request is not supported, and some other value if any other "
        "error occurred. In a subclass, the set of possible return "
        "codes could be specified, using a ValueMap qualifier on the "
        "method. The strings to which the ValueMap contents are "
        "'translated' may also be specified in the subclass as a "
        "Values array qualifier.") ]

    "element by element basis.") ]

// StorageRedundancyGroup
// ===================================================================
[Version ("2.7.0"), Description (
    "A class derived from RedundancyGroup containing mass "

    "Groups are used to protect user data.  They act on one "
    "or more underlying StorageExtents, associated via "

        "=5) or \"P+S\" (7) may be specified. The value of 0, is "
        "defined as \"None\" to indicate that data redundancy is not "
        "active. An inactive redundancy should only be instantiated "
        "if data striping or concatenation are active. These are "
        "indicated by the IsStriped or IsConcatentated boolean "
