Rebuild Write Cache Nytro MegaRAID firmware supports drive cache properties during a rebuild operation. The Nytro MegaRAID caching solution temporarily enables drive cache for the physical drive that is being rebuilt for the duration of the rebuild operation. Users can enable or disable this feature using the MegaCLI feature. The Nytro MegaRAID 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.
