HP Configuring Arrays Reference Manual page 86

For controllers that support Auto Replace Drive, setting this value to AutoReplace enables a rebuilt spare
drive to become a data drive in the array. When the failed data drive is replaced, it assumes the role of the
former spare, eliminating the need for a second array rebuild.

The value for this option determines whether the array specified previously in the script will be configured
