[CentOS] LSI SATA MegaRaid & Centos 7 build 1511

Dear Alexander;
Thanks for your reply but what you are saying could apply in Europe and USA but not in Middle East.
I'm using these servers for around 5 years now and I know it's NEC with FakeRaid ; please check these photos https://drive.google.com/open?id=0BzqgoXi9IUMid3pNOXRZOHZuMkU
I totally agree with John; NEC sold these servers with fakeraid from LSI as I used to login to LSI Firmware to manage the RAID disks.
But when I install Centos 5.X/6.X 64bit; I can see the disks as standalone disks as well as dmraid devices.


# dmraid -rD
/dev/sda: ddf1, ".ddf1_disks", GROUP, ok, 974608384 sectors, data@ 0
/dev/sdb: ddf1, ".ddf1_disks", GROUP, ok, 974608384 sectors, data@ 0
It looks like kernel issue more than Centos 7 issue as I faced the same issue while installing Debian 8
