[gentoo-amd64] Trouble installing in server with Fusion-MPT SAS storage controller

[Clemente Aguiar]

We have just bought a IBM x3250 server which has a "LSI Logic SAS1064E
Fusion-MPT SAS" storage controller.

I am using Live CD install version 2006.1.

Standard installation goes fine: recognizes the drives, formats the
partitions, installs, no problem, but when I reboot ... the booted
system does not seem to recognize the controller.

I get the following error:

!! Block device /dev/sda3 is not a valid root device ...
!! The root block device is unspecified or not detected.
  Please specify a device to boot, or "shell" for a shell ...
Boot() ::

The module that during installation is loaded is "mptsas", but during
boot of the system it does not seem to load this module (at least I
cannot see it among the other dozen SCSI modules it is tying to load).

I think ths is a bug, and I have already filed it in bugs.gentoo.org,
but in the meantime can anybody give me some suggestion on what to do?

Don't compile as a module, compile it in. If you used the
livecd-installer, you'll need to build a kernel.
The kernel the livecd uses is rather bloated, and i dont recommend
that.

You can't use a module for the boot device.  You need to compile it into
the kernel, rather than as a module.

I doubt this is a bugzilla-worthy bug; it sounds like you've just
miscompiled your kernel.

Actually, the Live CD kernel uses initramfs, which is able to load at
boot whatever SCSI modules it requires to access storage (disk, raid
etc.).

I have installed Linux a few times with other SCSI and RAID controllers,
just having difficulty with this particular one.

I agree that it would work if I compiled the kernel with the required
SCSI drivers, but I would still like this puzzle solved.
