Considerations for Hot Spare Protection Policy
Considerations for Enclosure Affinity
The Hot Spare Protection Policy is supported only on Serial Attached SCSI (SAS) controllers.
The Hot Spare Protection Policy provides you with a higher protection level for the virtual disks by enabling you to specify the number of dedicated/global hot
spares to be assigned to the virtual disks/controller. You can also specify the severity levels for the protection policy. Dell OpenManage Storage Management
sends alerts when the hot spare protection policy is violated.
You can determine the hot spare protection policy best suited for your environment; however, Storage Management does not provide a default policy.

Resetting the Hot Spare Protection Policy

Global Hot Spare Protection Policy
Considerations for Hot Spare Protection Policy
l The dedicated hot spare protection policy is not applicable to SCSI, SAS/iR, PERC H200, and CERC SATA 6ch/2s controllers.
l RAID 0 does not support assigning hot spares. Also, the protection policy is not applicable for RAID 0.
l For SAS/iR and PERC H200 family of controllers, you can assign only two global hot spares.
l If the status of the virtual disk is displayed as Degraded or Failed because of the hot spare protection policy violation, you must assign the required
number of hot spares (as defined in the protection policies) for the status to be displayed as normal.
l Hot Spare Protection Policy is not applicable to PERC S100 and S300 controllers.
Considerations for Enclosure Affinity
l Enclosure affinity settings for dedicated hot spare are applicable only on PERC 5 and PERC 6 family of controllers.
