How to restore raid?

Question

System administration

Good afternoon, please tell me about this issue

There is a gigabyte b450m ds3h board on it, I created a raid array (mirror) raid status "Ready". I installed the OS, set everything up, and decided to check if the computer would boot if I disconnected one disk. The computer booted up, the raid utility shows that the status of the raid is Critical. Okay, I'll plug the disk back in and the raid will recover, but I'm wrong here. I returned the disk, but it did not exit the status, in the utility it writes that the disk that I returned is in the "Ready" status and the second is Online. The question is how now to return it to the raid. And the status changed from critical to Ready?
In the utility settings, I could not find anything or any tools for this. Thanks
In the screenshot, I displayed the utility menu, here the status is ready, as it was originally, and both disks are in the array.

Answer 1

It is necessary to specify in the settings that the disk that you removed is a hot spare (Hot Spare). Then the controller will have to automatically enter it into the array and start rebuilding.
