How to solve this issue or get more information about this issue?

When I have connected D2D monitor an dkeyboard, there were no any warning or error on D2D console screen

If a Catastrophic RAID failure occurs then libraries will fail to start, however it sounds in this case as though the RAID is actually OK given the information from the GUI and console it sounds as though there is some other error here.
If a second reboot does not fix the issue, then you need to contact customer support in order to get support engineer intervention to resolve the issue.
