HPE DL120 Gen9 how to build a raid for Centos 7?

Question

linux

Comrades!
It's about to bleed from your eyes. I can't get the Italian centos to see the raid. Need help.
Made a mirror in iLO of the HPE DL120 Gen9 server. I started the installation, pressed E, entered modeprobe.blacklist=ahci inst.dd I
stuck a USB flash drive with a file downloaded from the HP site.

Everything went fine, no errors. BUT in the installer:

Raid does not smell.
I tried all the versions that were on the site. I don't know how else to make the server see the raid.

Answer 1

HPE DL120 Gen9 - if you did not order a separate discrete raid controller when buying, that is, only a soft trade that will be visible only if there is firewood for it, and then not always (verified by practice).
IMHO do not torment this matter and go straight to purely software solutions like mdadm and zfs

Answer 2

Your disks are not new and there is a mark about their use earlier (a mark that they were in a raid some time ago). You need to clean them with some kind of program (look in the internet). But the fact that they need to be reset from the last raid is 100% for the most, when it was like that, but I don’t remember how to throw it off. Look for something like "linux fdisk remove raid flag"
