Windows Server 2019 RAID1 failed redundancy

I have 2 online, dynamic disks in my RAID1. For some reason the volume has an exclamation mark on it and the status is Failed Redundancy. If I right click the volume and select Reactivate Volume, will the volume then revert to Healthy without any issue? The volume holds my SQL server and my databases so I really don't want any data to disappear.

    Hi,

    1. Would you please provide a screenshot of the RAID1 disks?
    2. Before we do any operations on the disks, please backup the data on the disks.
    3. Please check if the disks are inserted well.

    Thanks for your time!
    Best Regards,
    Anne
