Changing the Spare Management mode

The Spare Management feature provides multiple methods for handling spare behavior. You can choose
from the following options:

Dedicated Spare Drives—When the failed data drive is replaced, it must be rebuilt from the data on the
spare drive. In Dedicated Spare Drives mode, one spare can be dedicated to multiple arrays.

Auto-Replace Drives—The spare for the failed data drive automatically becomes the replacement data
drive. When the spare is replaced, the data drive does not need to be rebuilt. In Auto-replace mode,
spare drives cannot be shared between arrays.
If assigning Auto-Replace Drives mode to an array with a RAID 0 drive, Spare Activation Mode must be set to
Predictive Spare Activation mode.
