> Rebuild Write Cache

> Nytro controller firmware supports drive cache properties during a rebuild operation. Users can enable or disable this feature using the MegaCLI feature.

> The Nytro controller software automatically changes the setting for a drive that is being rebuilt. If the PD_CACHE for the rebuilt drive is already set, firmware does not need to do anything extra.

> Firmware identifies and sets the cache policy of the drives whenever a rebuild operation starts and the catch policy is reflected in the event logs. Firmware also makes sure to flush the cache just before committing the drive to the disk group.
