Changing the Spare Activation Mode
The spare activation mode feature enables the controller firmware to activate a spare drive under the following conditions:
•When a data drive reports a predictive failure (SMART) status
•When a data drive fails; this mode is the default.
In normal operations, and for older controllers, the firmware starts rebuilding a spare drive only when a data drive fails. With the predictive failure activation mode, rebuilding can begin before the drive fails, reducing the likelihood of data loss that could occur if an additional drive fails.
To change the Spare Activation Mode:
1.Open HP SSA.
