Hi,

I'm trying to install Gentoo (amd64 version) on Dell T110 II server with PERC H200 (Hardware RAID) card with RAID1 configuration.
I installed the system as mentioned in the handbook, but, it fails to boot from hard disk. I use "/dev/sda3" as my "/".
I've built RAID1 support to kernel (builtin).
The error is : Block Device /dev/sda3 is not a valid root device...
Could not find the root block device in .


Any help on fixing this error.....

Thanks

asankaan,

What does lspci say your raid card is?
lspci -k may even tell the driver in use. I suspect its missing from your Gentoo kernel.

The kernel raid1 option is only needed for software raid.

Google and guessing suggests you need
Code:
<*>   LSI MPT Fusion SAS 2.0 Device Driver (NEW)

Dear NeddySeagoon,

Thanks for your guidance, the problem solved!
I enabled the MPT2SAS driver (builtin) and it works fine!!!

Thanks a lot.
