What to do if the server cannot identify the AVAGO RAID card and shows an error message in device manager?


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.

On ND8301/ND8401, if one of raided HDD went defective, how can I rebuild RAID with new HDD?


On ND8301/ND8401, if one of raided HDD went defective, how can I rebuild RAID with new HDD?



Once you replace the faulty drive with a new one, an automatic rebuild will begin, and its progress will be indicated by a status bar as shown below.

The process will take hours depending on the sizes of your disk drives, e.g., 8 hours if using 2TB drives in a RAID5 volume.

If using a RAID5 volume, the recording task will be halted during the rebuild process. Recording will continue if using storage volumes in other RAID levels.

(For more detail you may refer to P.198)


Since ND8401 is on Windows Embedded OS, the functionality of RAID is provided by Intel driver, in other words, it would also determine when to rebuild RAID.
If automatic rebuild did not start just in place, you could go to Setup Wizard and try to rebuild RAID manually,


What is the rebuild machanism of ND8401/ND8301?


1. When will the ND8401/ND8301 do rebuild?
2. Can we cancel the rebuild function?

3. Is there any work around to avoid rebuild?



1. When will the ND8401/ND8301 do rebuild?
If ND8401/ND8301 is powered off abnormally, it will do rebuild when next power on.

2. Can we cancel the rebuild function?

No, we can’t. The rebuild mechanism is defined in hardware level.

What our software can do is to stop the VAST service during rebuild.

3. Is there any work around to avoid rebuild?

If you use RAID 5, we suggest to use UPS to stablize the power.

If the period of abnormal powered-off is longer than what UPS can support, please buy the UPS which can support to powered off the server automatically.

Hence, ND8401/ND8301 won’t do rebuild when next power on.
