Put RAID5 failed to Online.

[Vince5]

Hello,

I have a problem with my Raid5. In a same time, on 3 disks one is failed and the second is unknow. This just after a power on of PC.

I can put the failed disk to online and I replaced the unknow drive.

Today I have in the Raid5 config two disks online, one unknow (I can't remove it) and the new disk in good state but as a simple disk. I can't start the rebuild and the Raid5 stay failed.

Is it possible to pass the Raid from failed to online state in "manual mode" and start the rebuild with the new disk ??

The board is an ASUS Z790. The UEFI bios is in last level 1663 and I use Intel optane memory and storage management 20.0.1011.

Thanks for your help.

Hi Vince5,

Thank you for creating a thread in Intel Communities.

I may have a recommendation to fix the issue that you are experiencing; however, I need to determine if it applies to your configuration. Kindly provide the following, so I can determine this:

1. Kindly share a screenshot of the status of the drives from Intel Optane Memory and Storage Management.

2. Please provide the complete model of your motherboard

3. Provide also the brand and model of the drives and are they using SATA or PCIe NVME.

Looking forward to your post.

Hi Alfred,

Thanks for your feedback.

Finally I created a new RAID5 and say good bye to the old files.

But if you can give your recommandation for the other guys who have the same problem or for me if it's fall againyou will find the specification of my config.

My Board is a ASUS Prime Z790-A Wifi.

Disks : 3 Seagate Barrracuda ST2000DM008 2 TO SATA3.

State of disk (today) : Previously the first disk was in unknow state without information and the Sata_Array was failed. The two other disk were in good state.

Thanks.

Nice day.

Hi Vince5,

Thank you for waiting for our update.

We appreciate your concern for other users that may encounter this issue. We have a prepared a list of steps below to fix the problem that you reported:

To rebuild a RAID 5 volume, try resetting the disk to normal, which will prompt the volume to start rebuilding automatically. Intel® Optane Memory and Storage Management tool does not allow to do this procedure. This is using Raid BIOS.

Resetting a disk to normal (non-RAID) means it is needed to enter the CTRL + I menu and choose the options below:

1.     Press < Ctrl > < I >  when prompted to enter the Intel® RAID Option ROM utility.

2.     Use the Up and Down arrow keys to highlight the RAID volume to be reset and press < SPACE > to select the disk(s).

3.     Press < ENTER > to complete the selection.

4.     Press < Y > to confirm the reset.

The options may vary from one manufacturer to another. Check with the computer manufacturer (OEM) in case further assistance is required to access the Intel® RAID Option ROM utility.

If the read/write data access consistently fails, the disk will likely return to a failed state immediately and it will be needed to rebuild the volume to another disk.

If a SATA disk is compatible, available, and normal, follow this procedure to rebuild the volume:

1.     Launch the Intel® Optane Memory and Storage Management tool.

2.     Under Status, click on Rebuild to another disk.

3.     Select the disk you want to use to rebuild the volume, and then click Rebuild.

4.     The rebuild operation starts immediately. Users can follow the progress by hovering over the notification area icon or by reviewing the volume status under Status or Manage.

5.     Once the operation successfully completed, the array disk and volume status will display as Normal.

Note:

If there is no available disk present, you will need to power off the computer and connect a new SATA disk that is equal to or greater capacity than the failed disk. Once the computer is back up and running, follow the rebuild procedure described above. If this is no success. it will be needed to recreate the array.

Users should always perform backups of their information before attempting any step or procedure on any storage device or system.

We hope that we have provided you the answer that you are looking for.
