ServeRAID information
In some cases, the ServeRAID controller will automatically reset the drive to the
Hot Spare or Rebuild state. If the drive state change does not occur automatically
(amber LED stays lit), refer to your ServeRAID documentation for information
about manually changing the state of the drive from the current state to another
state, such as Hot Spare or Ready. The amber LED should turn off within 10
seconds after the drive-state change.
