Installing RAID 0

Asked by Keman

Hi for all !
i have some problem and i hope you can help me to solve it :-)
i have computer with raid 0 working on it. the raid controller is SIL 3512 and MOBO is Gigabyte GA-K8NS939-Ultra.
I using the Silicon Image RAID 0 becose the SATA plags is in the good place on the MOBO and this raid is faster then NForce3 RAID.
The controller is working great and HDD's too. BUT
when i running the Ubuntu 7.04 LIVE CD is realy not seeing my hard drives. In Windows Installation i have to press F6 in the start of it and install RAID controller from floopy manualy.
How can i do that in Ubuntu ?

Thanks for answers :-)

Hello,

Can you configure your RAID (in BIOS perhaps) to treat HDDs attached to it not as parts of RAID 0 or 1, but as ordinary HDDs? If this makes the HDDs visible to the installer, you will be able to create a software RAID during installation

Hi Dmitry ! Thanks for the answer.
BUT i dont want to create software RAID i want to use my existing configuration on the computer.

How can i do that ?
May be i need to change something before the instalation ?
or may be i need to add some files to some folder ?
I can download the drivers for the raid from the manufacturer site and i have them on my computer.
Thanks.

Does the company that produces these RAIDs offer Linux drivers for them that can be used in Ubuntu? I can't find drivers for Ubuntu there: http://www.siliconimage.com/support/supportsearchresults.aspx?pid=29&cid=3&ctid=2&osid=1&

It seems that creating a software RAID is the only solution for this problem

See, you can use the drivers that use the same kernel.
I think the Ubuntu and the red hat using the same.

my question is not find drivers, but what can i do with them :-)
where i can put or copy them to let the system find my hardware befor installing Linux.
i starting up my computer from the live cd and it can not find the HDD's !
thanks

Different Linux distributions use different kernel versions. I seriously doubt you will be able to use drivers for Red Hat with Ubuntu.

As for installation instructions, it seems they are included in the archives with the drivers, for example SWD-003x12-10LR5-1058.zip contains REDHAT_DRIVER_README_FULL_Installation.txt

Hmm....I knew that the Ubuntu has the DEBIAN kernel.
Some one of them has it ?
I mean the drivers in the list.

thanks.

Looking at this, it seems that this is an onboard SATA RAID controller, these are *NOT* hardware RAID controllers in the true sense. They generally implement some base functionality in the driver / software. (Think WinModem, if you're familiar with them) - I have an older Silicon Image controller in an NFORCE-2 board I had, and experienced the same problem. It might be possible to get this working, but I honestly think for something as primary as your disk, that it's an accident waiting to happen.

As an aside, I would highly suggest not using this onboard RAID, nor a software RAID-0.. the performance benefits from either of these two solutions are dubious.. If you really require a more performant disk solution, I'd look at some add-in (PCI-X / Express) RAID solutions (Promise Technology has been good for less-expensive solutions, and offer open source drivers)

No, it seems this is a standalone PCI card: http://www.siliconimage.com/products/product.aspx?id=29

Keman,

If this is an onboard raid controller, it is probably like, as Krash says, a winmodem, where most of the actual work is performed not by the hardware, but by software in the driver. If you partition the HDDs attached to the RAID as a software RAID, you may even get a performance gain from this operation.

There is even a document at the download site mentioned above that explains what software RAIDs in Linux are

Thanks for all...a problem is solved :-)
I have new computer - the beast one, overclocked Q9550 on ASUS ROG MoBo, and have Vista 64 bit and Ubuntu 8.10 in dual boot on it.
Like a smart man said - no computer - no problem :-)

so, grub 1.98 works perfect with ISW.
u can use deb from here: https://edge.launchpad.net/~ricotz/+archive/unstable

also, u can run following command to use default settings:

$ sudo dpkg-reconfigure grub-pc
