270 Protecting Your Virtual Disk with a Hot Spare
Setting Hot Spare Protection Policy
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.
Storage Management does not provide a default policy; however, you can
determine the hot spare protection policy best suited for your environment.
