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.
'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.'
'The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.'
'RedundancyStatus provides information on the state of the redundancy group. "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.'
'The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.'
