redundancy.
-a Auto Rebuild provides optimum protection against
disk failure by rebuilding a failed disk as quickly as

disk array vulnerable to a second disk failure until a

-i Auto Include simplifies the task of adding a new
disk to your array. Disabling it will require you
manually to include each disk you install in the
array.
-p Rebuild priority determines how quickly a rebuild
operation will complete.
