Block Change Tracking(RAID bitmap)

Request :: P00037650
Unfortunately, the MegaRAID controllers and SAS HBAs do not currently support this feature. There is discussion of future enhancements with a feature set such as this but nothing concrete. I will see if I can find out more information. However, the LSI 3ware controllers do offer a feature that is similar, but not exact, called RapidRAID Recovery.
