Raid failed after BIOS update

I created two RAID volume using Intel Optane Memory and Storage Management, one is a RAID 0 with 2 disks and the other is a RAID 5 with 4 disks. After updating the BIOS, IOMSM prompted me for a RAID failure when I entered windows, and showed that the RAID 5 volume became 5 disks, 3 of which were unknown hard disks; while the RAID 0 volume became only 1 disk (as shown in the screenshot, SATA_Array_0000 is the RAID 5 volume and the disks showing 0 Bytes was marked as unknown hard disk (未知硬盘 in Chinese). While the PCIe_Array_0001 below is the RAID 0 volume). Also, I found the 3 disks that should have been in the array in the non-RAID disks, namely the one shown as PCIe固态硬盘 (1908 GB) and those shown as SATA固态硬盘 (3726 GB) (固态硬盘 means SSDs). IOMSM doesn't seem to have any options for repair, I only found the "Delete Volume" and "Mark as Normal" options in the selected volume's view.

I haven't done anything with these volumes and disks since the problem appeared. Is there still any way to recover these RAID volumes? Also, are there any other operations (e.g. hardware changes) other than operations on the BIOS that can cause this?

Hello ccmmk2, 


  

Thank you for posting on the Intel® communities. I am sorry to know that you are having issues with the Intel® Rapid Storage Technology (Intel® RST).  

  

In order to better assist you, please provide the following:  


1. Are you using a laptop or PC?

2. What is the brand and model name of your laptop or motherboard (if desktop)?

3. Are you using the Intel® Rapid Storage Technology (Intel® RST) version from the Intel website or the computer manufacturer's website?

4. Did you back up your data?

5. Did you tried reinstalling the operating system and recreating the RAID configuration?

Hello @DeividA_Intel ,

Thank you very much for your reply.

  1.  I'm using a PC.
  2. The motherboard is MSI MAG Z790 TOMAHAWK WIFI.
  3. I used the Intel RST driver provided by MSI official website, and the version is 19.5.0.1037.
  4. Yes, I have backups for most of my data, but I still want to retrieve those that are not backed up if possible.
  5. I have not done any thing to the OS or RAID configuration, and the OS is not running on the RAID volume either before or after the BIOS update. I just enabled Intel RST in the BIOS because the update seems to have reset my BIOS settings causing Windows to fail to boot.

P.S. Sorry, I seem to have got the wrong way of replying...

Hello ccmmk2, 



Thanks for your patience. In this case, since the issue started after a BIOS update you may need to check with MSI, this is because there is a possibility that some feature was removed despite you enabled the option in the BIOS.


Please, check with MSI to confirm the proper settings for the Intel® Rapid Storage Technology (Intel® RST) based on their BIOS and system.



Please keep in mind that this thread will no longer be monitored by Intel.
