Right. Have you configured the server, via the firmware, to present the
drives or RAID as a logical drive? Some of those controllers won't let the
server find the drive if you haven't done that.

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 !!

afaik, the megaraid cards are mostly all SAS, which support SATA drives, 
except very old ones were SCSI.

Ok, I do see they had a series of MegaRAID SATA 150-xx and 300-xx cards, 
these were 64 bit PCI or PCI-X cards.

95Q9 does not appear to be a valid card number, 9240, 9260, 9280 are 
some pci-express SAS MegaRaid cards....

if you want help, please don't guess what you have, figure out what it 
actually is.    the output of `lspci -nn` will identify all boards in 
your system, for instance...
