Make sure your kernel includes the driver for your sata (or scsi) controller.

well, the "genkerneled" kernel should be the same kernel like from the installations cd... and with the installation cd i don't have any problems.
however, i don't know if the sata driver is included into the kernel or if it's a module. and i don't know how to find it out.
could it be, that (if it's a module) it has to be included into a "solid" kernel to work? and if yes, how do i change the "genkerneled" kernel?

The issue is that the install CD isn't booting from the SATA drive, so it can work okay with the driver as a module that is discovered with UDEV. For practical purposes, the boot device's drivers must be built into the kernel. CD drivers are built-in on the install CD's kernel.

You find out what your hard drive controller is by using "lspci". You change the genkernel configuration by adding the "--menuconfig" option to the genkernel command line. Go to the device drivers section and hunt around.

i made genkernel --menuconfig all and set the sata drivers as included it the kernel up, but it didn't work. i believe, there is some strange problem with my kernel at all. i just wrote about it in another topic: https://forums.gentoo.org/viewtopic-p-4185359.html#4185359

Describe "didn't work" in a little greater detail, please. Also, one technique you can use to be sure that you have the correct driver built into the kernel is to boot the install CD and use "lsmod" to locate the driver that it is using. Then, go back into genkernel and ensure that that driver is built in.

By the way, the option you want to preserve your configuration changes is --save-config.

hmmh... either i forgot an important option or there where some problem with the sources. however, after reemerging gentoo-sources and setting everything up with genkernel --menuconfig all everything worked out and works just perfektly right now.
thank you for your help!
