This section describes the procedure for manually rebuilding a degraded array when Auto-Rebuild is disabled and a dedicated spare drive is not available. You must have at least one unconfigured hard drive in the enclosure to perform the steps below.
Rebuilding a degraded array
Select the degraded array in the Storage pane. You will recognize the degraded array by its yellow icon.
Roll over the Operation tab and select Rebuild.
LaCie RAID Manager displays hard drives that have not been added to an array.
Select a hard drive from the list and choose Submit.
Choose the Property tab for the array. The Background Activity State shows that the rebuild is running.
