similar to: SATA RAID - LSI Megaraid SATA 150-4

Dear All; I want to install Centos 7 latest build on NEC Server 5800/120b-2. The installation wizard fails to detect the storage connected to LSI SATA MegaRaid PCI. Centos 5/6 were working fine with this H/W configuration but not the case with Centos 7. Please; advise. Fawzy Ibrahim Redhat Certified Engineer

The NEC compatibility page at http://www.nec.com/en/global/prod/express/linux/centos.html indicates that the R120b2 is not certified for CentOS 7. CentOS 5 and 6, yes, but not 7. As there are other servers

This is particularly likely if this same hardware has been used with "CentOS 5/6" as reported in the original message.

I have tried many permutations of search terms in google and I haven't been able to find any confirmation that the megaraid* modules in centos4 supports port multipliers/multiplexers. Here is a link to the controller I have in mind at newegg: http://www.newegg.com/product/product.asp?item=N82E16816118032 In case anyone is interested, here is what my research has turned up when looking for

Hi; LSI SATA MEGARAID 95Q9 as I remember. I have configured it through the firmware and I have created RAID-1 VD. But when I start the Centos 7 installation; I can not find any disk !!

I don't see any LSI hardware in there, at all. Drivers or no, it should show up. Are you sure it's plugged in? Do you see the LSI firmware on the monitor during the boot process?

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

There's no option in BIOS to disable the RAID mode; this is NEC servers !! Also; I have found that it's a bug in Centos 7 as per this pages:- https://www.centos.org/forums/viewtopic.php?t=49069 https://bugs.centos.org/view.php?id=9813 From: Fawzy Ibrhim <fawzy_ibrhim at yahoo.com> To: CentOS mailing list <centos at centos.org> Sent: Wednesday, August 17, 2016 5:41 PM

So; there's no hope to install Centos 7 on this H/W?

I have opened the case of the server and it's LSI card with FakeRaid !! What I have to do now as lspci shows it as intel cards?

In your original message, you indicated that this was a PCI card, but it looks like this is just a firmware component of your motherboard. I think you should assume that this firmware is unsupported. Set your SATA mode

I guess module ioatdma is missing in Centos 7:- 00:16.1 System peripheral: Intel Corporation 5520/5500/X58 Chipset QuickData Technology Device (rev 22) ??? Subsystem: NEC Corporation Device 8372 ??? Kernel driver in use: ioatdma ??? Kernel modules: ioatdma # lsmod Module????????????????? Size? Used by autofs4??????????????? 27000? 3 sunrpc??????????????? 267620? 1 8021q?????????????????

None of the missing modules appear to be related to RAID: autofs4, cpufreq_ondemand, freq_table, mperf, ipv6, microcode, power_meter. Can you post the output of "dmesg" on your
