Hi,
unfortunately, the "Boot from a scsi disk" I posted before is
still not enough to boot from a scsi disk. Here's what
happens:
- autoyast automatically detects the scsi controllers
in the system. In one of my systems there are a icp vortex
and a adaptec controller.
- when writing the bootloader config, autoyast inserts the
scsi modules for the detected controllers at the beginning
of the INITRD_MODULES line in /etc/sysconfig/kernel
- unfortunately, *only* the scsi controller modules are
inserted, *not* the scsi_mod module. This results in
an initrd trying to load e.g. the gdth and the aic7xxx
modules without loading scsi_mod first (sd_mod is
loaded automatically).
Thus, the first boot attempt after the installation
ends up with unknown symbols in sd_mod, gdth and aic7xxx,
and the scsi disk to boot from cannot be activated and
the kernel panics.
- adding scsi_mod to the initrd modules in the bootloader
profile, does not work. When you specify
<bootloader>
<module>scsi_mod</module>
</bootloader>
that does add the scsi_mod modules to the INITRD_MODULES
value, but this step is done before the bootloader module
runs, and so it inserts the scsi controller modules
*before* the scsi_mod, thus the initrd still tries to load
gdth/aic7xxx *before* the scsi_mod.
- the solutions is to specify the scsi_mod *and* the scsi
controller modules in the <bootloader> section in the
right order,i.e.,
<module>scsi_mod</module>
<module>gdth</module>
This will finally end up with the INITRD_MODULES line
"aic7xxx gdth scsi_mod aic7xxx gdth"
where the last three entries come from the <bootloader>
specification.
Then, the mk_initrd script does some kind of sorting and
inserts the scsi_mod as first module, resulting in a clean
boot from the scsi disk.
Anas: I think that autoyasts bootloader configuration module
should automatically insert "scsi_mod" as first module, when
it has autodetected and inserted any scsi controller module.
Or to insert the modules the user specifies on the <bootloader>
section at the head of the INITRD_MODULES list.
cu,
Frank
