Unrecoverable Media Errors Detected on Drives after hard drive replacement on RAID5 volume

[RemiBLTech]

Hi,

We have 3 customers where the replacement of one hard drive in a RAID5 logical volume throw the warning "Unrecoverable Media Errors Detected on Drives".

Steps :

Hard drive (SAS 10k) failure detcted

Replacement

Automatic rebuilt of RAID5

Warning Unrecoverable Media Errors Detected on Drives

HPE Suggestion Backup, RPI of the logical volume, Restore : how HPE can suggest this solution.  This leads to a production interruption of several hours.

For my customers cases,  i have the warning Unrecoverable Media Errors Detected on Drives durting the rapid initialization parity.

I have to use "erase one pass" of the beginning of the logical volume, then RPI and restore datas.

Can we hope for a real solution ?

The first link applies to other hard drive than my customers (EG00xxxJWJNx).

The second link talk about the warning on my 3 customers and the resolution is backup, recreate logical volume with RPI and restore. This is the main problem : it's anormal to stop our customer many hours.

Hi everyone,

after a discussion with HPE, I understand they didn't want ro recognize this problem. Quote "Thank you for the Post. We suspect it could be after replacement, during the rebuilding the Controller might have noticed the Media error which made it to report the Unrecoverable Media errors."

So the RAID Controller didn't solve a problem so I have to solve myself with data backup, delete logical volume, one-pass erase with 0, recreate logical volume, RPI, data restore.

It's a joke ?
