Figure 166 - HP Smart Array profile: Disk sparing – Multiple Spares
Redundancy sets can have multiple spares and also a disk drive can be a spare to more than one
redundancy set. In Figure 166, we see that HPSA_StorageRedundancySet:A has two CIM_IsSpare
associations to two HPSA_StorageExtent instances. Also, HPSA_StorageExtent:005 has CIM_IsSpare
associations to both HPSA_StorageRedundancySet:A and HPSA_StorageRedundancySet:B.
9.8 Disk Sparing - Drive failure example
The following sections describe the implementation of Disk Sparing for Smart Array controllers.
