RE: [Xen-users] Compiling Kernel with raid driver for my Dellpoweredge 2850 RAID Controler

["Nicolo" <nicolo@xxxxxxxxxxxxxxx>]

When I try :
mkinitrd -k -o /boot/initxen.img 2.6.16-xen

I have an error on my megaraid2 module :

/usr/sbin/mkinitrd: The working directory /tmp/mkinitrd.TtbbHR will be kept.
/usr/sbin/mkinitrd: add_modules_dep_2_5: modprobe failed
FATAL: Module megaraid2 not found.
WARNING: This failure MAY indicate that your kernel will not boot!
but it can also be triggered by needed modules being compiled into
the kernel.

Some one know how to past it ?

Thanks

Nicolas

You have a choice: You can either include a "initrd" that has the
relevant modules, or use "bultin" rather than modules (i.e. give "y"
instead of "m" for the config entries - bear in mind that you may need
other modules for MEGARAID driver to work - lsmod should give you
details of which modules are linked to which other modules. I think for
example SATA requires SCSI drivers to be built too).
