•The replacement disk must be of the same protocol and disk technology. For example, only a SAS hard drive can replace a SAS hard drive; only a SATA SSD can replace a SATA SSD.
•The replacement disk must be of equal or greater capacity than the one it is replacing.
Using Replace Member and Revertible Hot Spares
The Replace Member functionality allows a previously commissioned hot spare to be reverted to a usable hot spare. When a disk failure occurs within a virtual disk, an assigned hot spare (dedicated or global) is commissioned and begins rebuilding until the virtual disk is optimal. After the failed disk is replaced (in the same slot) and the rebuild to the hot spare is complete, the controller automatically starts to copy data from the commissioned hot spare to the
NOTE: The controller automatically reverts a hot spare only if the failed disk is replaced with a new disk in the same slot. If the new disk is not placed in the same slot, a manual Replace Member operation can be used to revert a previously commissioned hot spare.
NOTE: A Replace Member operation typically causes a temporary impact to disk performance. Once the operation completes, performance returns to normal.
Controller Cache Preservation
The controller is capable of preserving its cache in the event of a system power outage or improper system shutdown. The PERC H710, H710P, and H810 controllers are attached to a Battery Backup Unit (BBU) that provides backup power during system power loss to preserve the controller's cache data.
