Changing the Spare Activation Mode

The spare activation mode feature enables RAID Controller to activate a spare drive under the following
conditions:

Predictive Spare Activation: When a data drive reports a predictive failure (SMART) status

Failure Spare Activation: When a data drive fails; this mode is the default.
In normal operations, RAID Controller starts rebuilding a spare drive only when a data drive fails. With the
predictive spare activation mode, rebuilding can begin before the drive fails, reducing the likelihood of data
loss that could occur if an additional drive fails.
