Figure 14 - HP SAS HBA profile: Disk sparing – Pre failure
Figure shows a three drive raid set with one spare drive. OperationalStatus for all the drives and the
storage volume are “OK”. The data drives can be identified by their MemberOfCollection association to
the StorageRedundancySet instance. The spare drive can be identified by its IsSpare association to the
StorageRedundancySet.
