Consider Global Hot Spare Policy when determining Virtual
Disk status
Storage Management considers the Global Hot Spare policy to
determine the status of the virtual disk. The status of the virtual
disk is determined by the severity level you specify for this policy.
NOTE: When assigning a global hot spare, consider a physical disk that has higher capacity, which can replace a disk
when a disk fails in the controller.
Considerations For Hot Spare Protection Policy
• The dedicated hot spare protection policy is not applicable to SAS/iR, PERC, and H200 controllers.
• RAID 0 does not support hot spares or protection policy.
• 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, then 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, S130, and S300 controllers.
Considerations For Enclosure Affinity
• Enclosure affinity settings for dedicated hot spare are applicable only on PERC 6 family of controllers.
• Enclosure affinity settings for a global/dedicated hot spare are not automatically set when you upgrade to version 6.1.
