data lost after extend raid

Kpindotchin — Wed, 14 Apr 2021 14:26:14 GMT

Hi Team

I performed a disk upgrade on hpe dl 380 Gen 8 server there were already 5 disks distributed as follows:

2 * 146 Gb (Raid 1) _System

3 * 600 Gb (Raid 1) _ Data

Actions taken: extension of Raid 5 with the addition of 3 new 600GB disks Result: the disks added to raid 5 but the old raid no longer exists at the level of the D4EXPLOITATION system the partition is no longer accessible the disc is converted to RAW format

is it possible to rollback?

Really Urgent

Hello,

I hope you have the complete data backup.
Or
In this situation, you have to take complete data backup before performing such activity.

I can suggest you try to update the SA controller firmware with the latest.
You can try to log a proper case with HPE, and share the appropriate logs for further analysis.

Please let me know if you have any quires.
