It's fakeRAID but I do not know why there's no LSI cards in lspci output !! To manage the disks; I have to use the LSI Sata Megaraid fireware; so is there any hope to install Centos 7 on this H/W? I have three servers from this model and I was planning to use them as test environment for me. Is there any way to rebuild kernel drivers or by pass boot parameter dmraid=yes while installing Centos 7?
