When I boot my system I see two boot options.

windows server 2012- current os

1. windows server secondary plex.

Fix

1. Start with option “Windows server 2012 – secondary plex”
2. Login as Administrator
3. Start Disk Management (right click on Start and choose Disk management)
4. You’ll see Failed Redundancy, if both disks are Online then right click on red colored disk area and choose “Reactivate Volume“
5. After complete, the disks should have a status “Healthy”. I could take hours.
