  • In OMSA, go to Storage, PERC, Information/Configuration (link at top of page), then Foreign/Clear from dropdown menu of available tasks for the controller.  Then go to Storage, PERC, Virtual Disks, and select Assign Hot-Spare from dropdown menu ... the only drive it should show you is the new one you just put in ... select it to assign it as a hot-spare, then the rebuild should begin shortly.
