One or more boot drivers require configuration changes. Press any key to load the driver health manager for configuration

Hello,

I have 3 DELL R740 server. Each one has 5 data disks, each disk is configured as a Raid0. Each sever has 1 catch disk, configured as Raid0 also.

Now server 1 and 2 has one data disk fault respectively, and server 3 has the catch disk fault.

All srevers give the warning 'One or more boot drivers require configuration changes. Press any key to load the driver health manager for configuration' in the process of restarting. Starting process stops at this place, can not enter system, and will loop over here again when next time restarting. 

I restart the server 2 for some times, and somehow it got in the system finally. Then I can still see the fault disk in both physical and virtual disk management interface.

But for the other servers, I did not have them restarted by manually restarting.

For the server 3, I clicked Discard Preserved Catch in the Action list, then it got into the system, but the catch disk disappeared completely in the GUI.

Questions:

1. Is the preserved catch taking all the data in the fault disk? Can I get all the data back if I use a replacement disk, to replace the fault data disk in server 1 or 2.

2. For the server 1, can I still get into the system still with fault disk visible in the GUI? What should I do?

3. For the server 3, have the catched data been discarded? Is there any way to find the data in the catch disk?
