NOTE: For PERC H700 and PERC H800 controllers, you can assign a dedicated hot spare to RAID 10, RAID 50, and
RAID 60.
Considerations for Multiple Dedicated Hot Spares From Storage Management version 3.1 onwards, you can assign more
than one dedicated hot spare to a virtual disk.
Considerations For Hot Spares On PERC S100, PERC
S300, PERC S130 and later controllers
For the PERC S100, PERC S300, PERC S130 and later 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 included in the virtual disk are not rebuilt.
On the PERC S100, PERC S300, PERC S130 and later controllers, individual physical disks may be included 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 PERC S100, PERC S300, PERC S130 and later controller cannot be
used as a member of a virtual disk.
NOTE: Hot Spare Protection Policy is not applicable on SWRAID S100, S300, S130 and later controllers.
Size Requirements For Global Hot Spares On S100 And S300
Controllers
When assigning a physical disk as a global hot spare on a PERC S100 and PERC S300 controller, the physical disk should be
equal to or greater than the largest physical disk on the controller.
