The Description property provides a textual description of the object.
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.

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.
