1. After confirmation, the problem occurs after the server mainboard is replaced. The cause may be that some components are not properly connected.
2. Remove and reinsert the hard disks. The problem persists.
3. Remove and reinsert the RAID controller card. The problem persists.
4. Remove and reinsert the cable that connects the RAID controller card and the iBBU. The problem is solved.
The cable between the RAID controller card and the iBBU is not properly connected. As a result, the RAID controller card cannot detect hard disks.
Connect the cable between the RAID controller card and the iBBU again and ensure that the cable is properly connected.
