Configuring Arrays on HP Smart Array Controllers Reference Guide

HP Array Configuration Utility 78
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.
Behavior Description
Dedicated
Default value for spares
AutoReplace
The spare drive becomes a data drive
when the rebuild is complete.

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