Data loss after HDD replacement on ProLiant DL380

[teckel]

Hi all,

After a HDD replacement on my server, I can't access the data on it;

I have a ProLiant DL380 Gen9 with 8 Hard Disk Drives configured in RAID 1+0 on a smart array P440ar controller. HDD n°1 mirror HDD n°8, HDD n°2 mirror HDD n°7, HDD n°3 mirror HDD n°6 and HDD n°4 mirror HDD n°5.

I had HDD n°3 and n°6 in Predictive Failure status. By mistake both HDD were remove at the same time, de-enabling the smart array controller (see Pigure 1).

I put the old HDD n°3 back and a new HDD position n°6. I re-enabled the controller, it was rebuilding data and once the data rebuild from 3 to 6, I replace the HDD n°3 by a new one. The data was rebuilding from HDD n°6 to HDD n°3 (See Picture 2).

Even if all the data stored on HDD n°3 and n°6 (mirror) are supposed to be recovered (see Picture 3), I still can't access the data on my server. On a reboot I can see the error message      -       1716-Slot # Drive Array - Unrecoverable Media Errors Detected on Drives      (see Picture 4)

I lauch a diagnostic and HDD n°3 and n°6 failed the Random Read Test (See Picture 5).

Do you know what happened and what can I do next to recover the data?

The Error you mentioned "1716-Slot # Drive Array - Unrecoverable Media Errors Detected on Drives "
