Hello Giampix,

Thank you for posting in Intel community Forum.

For me to further check this, please help provide the following details:

What are the status of all the RAID volume right now?
Are all of the replacement disk gets recognized in the physical disk view?
Did you use the same model and capacity of the replacement disk from the existing disks?
What are the troubleshooting steps that you trued so far?

If you have questions, please let us know. Thank you.

Hello Giampix,

Thank you for the update.

Based on your reply, let me ask additional details:

Do you have a data back up for RAID 10?
Which port did you install the 5th drive?
Let me also clarify the 5th drive. Is it a new drive or this is the drive that failed in RAID 10?
If the 5th drive is a new drive, did you use the same drive model and capacity?
Also, base on your screenshots, the system still has an OS. The OS is installed on a different RAID volume?

If you have questions, please let us know. Thank you.

Hello Mike,

Thank you for the update.

Do you have a data back up for RAID 10? I have data backup, I should only install OS Windows server again
Which port did you install the 5th drive? This is the strange thing, there are only 4 disk
Let me also clarify the 5th drive. Is it a new drive or this is the drive that failed in RAID 10? It's the broken one - Disk in slot0 is the new disk
If the 5th drive is a new drive, did you use the same drive model and capacity? YES same capacity 1TB and block size
Also, base on your screenshots, the system still has an OS. The OS is installed on a different RAID volume? NO

Hello Giampix,

Thank you for the update.

Good thing that you have a data back up because as a rule for RAID, you cannot rebuild a RAID volume if the RAID is already failed. You can only Rebuild a RAID if the status is Degraded.

However, let's try and hopefully this rebuild the RAID volume.

Please move the new drive and install it in the 5th slot because the RAID controller might be looking for a RAID drive member on that port.
Then follow the steps on this link: https://www.intel.com/content/www/us/en/support/articles/000006418/technologies.html

By the way, It is also possible that the hot spare that you created was not tagged as Global hot spare during creation that is why it did not kicked in.

If you have questions, please let us know. Thank you.

Hello Giampix,

Thank you for the update.

I am glad to hear that. Actually that is going to be my next recommendation if after following the link did not rebuild the RAID. Good thing you have a data back up to easily re-create the RAID and load the data back up.

Since the RAID is now restored, I need to close this inquiry.

If you need further assistance, please post a new question as this thread will no longer be monitored.

Thank you and have a great day.

If you have questions, please let us know. Thank you.
