What is ibmSystemSmartDiskDefunct?

A read-only boolean that is true if the drive is defunct, referencing the underlying IBMPSG_StorageFailurePredictionSettings.Defunct property. This tells an admin whether the disk has already failed or been marked non-functional by the system, a clear signal that the drive needs replacement. A drive reporting ibmSystemSmartDiskDefunct as true needs to be physically replaced as soon as possible.
