Abstract
The present invention is directed to a system and method for increased data availability. In an aspect of the present invention, a method includes receiving a SMART indication from a data storage device included in a plurality of data storage devices configured as a RAID array. Data from the data storage device which originated the SMART indication is replicated to a second data storage device. The second data storage device was not originally configured in the RAID array with the plurality of data storage devices for data storage. The data storage device which originated the SMART indication from the RAID array is removed, thereby resulting the second data storage device and the plurality of data storage devices configured as a RAID array.
