Question
What to do if the server cannot identify the AVAGO RAID card and shows an error message in device manager?
Answer
If you access the MegaRaid Storage manager and find out that you cannot login into the system because the software cannot find the RAID in the system (Please see picture below), it could be due to a number of factors such as improper installation, system configuration issues, or hardware issues. :

Here are some steps you can take to troubleshoot the problem:
Verify RAID card status: Access the windows "Device manager" and check the status of the RAID card.

Verify RAID card LED status: Check that the RAID card LED are ON and are working correctly. For more information please refer to the following link: [NR9X8X/NR9X8X-v2] MegaRaid RAID card SAS Activity LED.
Check physical connections:. Make sure that the RAID card is properly seated in the PCI slot. If you've recently moved your server or installed new hardware, it's possible that the card has been dislodged.
If everything is working at it should, the problem may be related to the BIOS configuration, to verify please follow the next steps:
Step 1. Reboot the NR9X8X-v2 and click "delete" when on the booting process to log in to the BIOS.
Step 2. Go to "Advanced" > "CSM Configuration" and change the Storage to "UEFI" and click "F4" to save & exit.

Note: the BIOS configuration for the storage should be UEFI as default.
