Considerations for Hot Spares on software RAID controllers
For the software RAID controllers, a hot spare is assigned to a virtual disk. When a physical disk fails, only the portion of the physical disk containing the virtual disk is rebuilt onto the hot spare. Data or space on the physical disk is not in the virtual disk are not rebuilt.
On the software RAID controllers, individual physical disks may be in more than one virtual disk. Assigning a portion of a physical disk to a virtual disk does not preclude the remaining portion of the physical disk from being used by other virtual disks. Only the virtual disks to which the hot spare is assigned are rebuilt. When using Storage Management, a disk that is assigned as a hot spare on a software RAID controller cannot be used as a member of a virtual disk.
NOTE: Hot Spare Protection Policy is not applicable on software RAID controllers.

NOTE: When you remove the hot plug from a physical disk that is assigned as a global hot spare and dedicated hot spare, the
PDR33 and
PDR31 alerts are not logged in the
Alert Log page. This functional behavior is observed on physical disks that are attached to PERC software RAID controllers.
