Hello, i hawe a hp proliant Gen8 microserver with two hdd prepared for raid; in HP defaul storage manager software i sucesfuly created raid array, but when running gentoo it dows't show the array, it shows the two hdd. After some researches i find out hat i need to install raid driver for hp proliant microserver gen 8, but on manufacturer page there are aviable drivers just for fedora and suse. My question is: can i install redhat 7 driver on gentoo? is there a driver for this raid controler for gentoo? Thank you!

When you can see 2 drives then there is no hardware RAID, obviously. Read about software RAID here: https://skrypuch.com/raid/

Bicker,

Welcome to Gentoo.

You have some form of fakeraid. Please post the output of lspci.
What raid level do you want to use?
Do you want the root filesystem on the raid set?

If its Intel Rapid Storage Technology, that can be made to work with mdadm.
If it needs dm-raid, the only excuse for dm-raid is that Windows needs to share the same raid set.

Real Hardware raid will cost as much as a whole HP Microserver.

The B120i is a fakeRAID controller. Don't use it! If you see 2 drives under Linux: good. Either use them as they are or use mdadm to create a softRAID.

Please look at this post from Fitzcarraldo for BIOS settings.
