What's the proper method to force a rebuild to a hotspare drive? We have drives which are reporting media/other errors, and want to RMA them.

In the GUI (we are using Intel/LSI controllers), we see the online drives and the hotspare listed. We also see dropdowns next to the Online drives to set them Offline, as well as a checkbox to "prepare for removal."

So, what's the proper sequence which will force a rebuild onto the hotspare (global hotspare)?

Set the drive Offline, then Apply, then mark for removal, then Apply? Or can both be done at the same time? And will this force a rebuild?
