CentOS

No, see above.

Is it possible to run kernel higher than 3.1 on centos 7?

Yes. We already ship 3.10 and 3.10 is 9 versions higher than 3.1.

It's "10" not "1" or "2" and 10 is larger than 1 or 2.

oh yes sorry I see. than controller should work, but still can't recognise disks.

I have changed controller, it is also Delock but another controller and now it works.

I found out what was a problem.
It was a power cable for disks I tried all power cables from PSU and didn't worked after that I use splitter 4 power pin to two sata power connector and now works like it should.

Splitters cause problems. Sometimes -- many times -- the problem is simply the splitter has not been pushed in tight enough and there is a poor connection made; other times it is simply a faulty splitter, which can be fixed f you roll up your sleeves. That is usually true for Molex connectors, OTOH if it is SATA ->SATA connector I simply toss it, unless only one branch of the Y is dead and all I need is an extension, in that case I simply tape off the BAD end so I know not to use it. It is usually a good idea to buy a few extra extensions / Y's at the time you buy the first... just in case, that you you don't waste a lot of time. It is usually a quick way to troubleshoot a power problem -- if it only happens with one extension /Y but not another you know where the problem lies; OTOH if it is a repeatable problem then the problem probably lies in the PSU. (Been there; Done that).

this time splitter solve a problem because all sata power connectors from PSU didn't work.

If I am reding your post right, did you have to effectively use 2 separate power connectors from the PSU and feed them both into a splitter in reverse so that both were powering the drive at the same time? If so then I suspect your PSU is junk.

No I didn't, I use the same cable from PSU for both disks and I have the same now with splitter
