Cannot see disks while tryin to install CentOS 7 at IBM X3550 M3
It shows that no disk present insystem, though 2 disks inserted (using RAID controller).
is ther e anything should be done so CentOS become to see disks?

Do you have the necessary driver for the RAID controller loaded?

I hope this helps.

I am new in CentOS, can you please let me know how I can load drivers so it would be loaded before installation begins?

Nothing different to any other Linux here: use modprode and lsmod to find out which modules are loaded or load them respectively.

I hope this helps.

Thanks for the answer.
So it means that I have to run command line installer, right?
Can you please let me know if below sequence is correct:
download the driver
uncompress the .gz file
rename it from .dd to .iso
copy it to a fat formatted USB key
when you boot the installer add 'modprobe.blacklist=ahci inst.dd' on the boot line.

I have no idea as i have no 3550 at hand. Here is a link you might want to consult: IBM Infocenter

I'd say you follow what is in there, because the manufacturer usually knows best how to make his hardware work.

I hope this helps.

Okay, there is some issues with RAID controller, thats why I can't see drives..
Tried at another server - everything is fine.

Thanks for help!
