Protecting Your Virtual Disk with a Hot Spare 271
Global Hot Spare Protection Policy
Table 14-2. Global Hot Spare Properties
NOTE: When assigning a global hot spare, consider a physical disk that has higher
capacity, which can replace any failed disk in the controller.
Considerations for Hot Spare Protection Policy
• The dedicated hot spare protection policy is not applicable to SCSI,
SAS/iR, PERC H200, and CERC SATA 6ch/2s controllers.
• RAID 0 does not support assigning hot spares. Also, the protection policy
is not applicable for RAID 0.
• For SAS/iR and PERC H200 family of controllers, you can assign only two
global hot spares.
• 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.
• Hot Spare Protection Policy is not applicable to PERC S100, S110, and
S300 controllers.
Considerations for Enclosure Affinity
• Enclosure affinity settings for dedicated hot spare are applicable only on
PERC 5 and PERC 6 family of controllers.
