Hardware RAID1 ON HP PROLIANT ML110 G4?
 

Hi guys, after a few days of problems I will try to find my luck here with you..

well, I have a Hp Proliant ML110 G4 Server with 2 x 500GB SATA discs (same) where I want to install Centos 4.x

Installation is not a problem if I install straight without and RAID, and also software RAID is working but.. I want Hardware RAID..

I have also a USB floppy to load drivers with..

I have tried with many different distributions, Centos 4.2 and 4.4(32-bit and 64-bit)
Red Hat Linux Enterprise and SUSE, all with the same result.

I have tried different drivers for the SATA RAID, written to a floppy with rawwrite.
Both from HP website and from the cd that came with the machine.

And it looks good until I have to choose the disks where I want to install, it shows 2 disks
sda and sdb... It should show just 1 disk when I have created the array (RAID1 - mirroring)

I have tried to choose one of the disks and also both disks but then when it is installed and the reboot the system halts with a blinking cursor up in the left corner, the system won't start..

Why I want to make hardware RAID work is because if one hdd should crash I would like to replace the disk and reboot the system without errors... If I use software raid1 I cannot mirror the /boot, or??

Are there any experts in this area that can help me install the RAID1 on a HP proliant ml110 G4?

Or is it just not possible to install the hardware RAID1??

Please help....
Thnks!

Hi, welcome to LQ!

A quick search here brought this (I think) very valuable link regarding
your question. http://linux-ata.org/faq-sata-raid.html

Read it, find out what hardware is actually in the box, and come back
and ask again if the FAQ didn't answer your question.

Read Tinkster's link. If you still think you have a hardware RAID controller, post the make and model of the controller and maybe someone can help.

Can't be. No OS can see separate disks through hardware RAID.

"Can't be. No OS can see separate disks through hardware RAID."

I was trying to be kind.

Yeah, I know. :)

Hi again..

I've been looking around and the only thing I can come up with is following Controller:

Embedded 4 Disk SATA controller with SATA RAID 0/1 (from HP website)

Any help??

Not to me. Insert a Linux live CD and run lspci.

Hey again.. well I've looking around and as far as I can see it it a "fake-raid" so I
did the software RAID1 and made RAID1 on SWAP , /boot and the rest of the harddrive, I thnink that will work okay for me also.. I hope...

Next time when I buy a server I will have to check a little bit more =)

But thanks to all of you! Really!
