Hi Jiri.
Before starting the troubleshooting of the installation problem, can you
please confirm that you have enabled SCSI support in redhat73-cfg.h?
This is the line
/* #define SCSI_HOSTADAPTER aic7xxx */
It should be uncommented and aic7xxx replaced with the name of the
module for your controller (this should be sym53c8xx but I am not 100%
sure).
Gergely's suggestion is indeed valid: when using PXE you have much more
freedom in choosing how the install kernel can be configured, so that
you can pre-compile all needed modules in the kernel itself. Also,
setting up PXE now will help a lot when the number of nodes grows and
going around with floppies will become a burden.
If you cannot use PXE for these nodes, there might be other ways out.
One is to create a new install floppy with a kernel which includes all
needed modules. I do not know how to this but I can ask WP4 people for a
recipe.
On the other hand, from the dot.config file I see that the sym53c8xx
module you need is known to the kernel on the floppy as an external
module (CONFIG_SCSI_SYM53C8XX=m). When booted, the kernel looks for it
in the standard place, i.e. /lib/modules/<kernel version>, but on the
partition mounted from the LCFG server this path is not available, as
the kernel used to create the nginstallroot partition is 2.4.18-3,
instead of the required 2.4.18-18.7.x.cern (I assume the message you
reported has a typo in, as 2.4.18-18.7.x-cern is not a valid kernel
version).
To fix this you can update the kernel version used in the nginstallroot
partition.
1) download the rpm with the correct version of the kernel. One copy is
in
/afs/cern.ch/project/linux/redhat/cern/7.3.1/i386/RedHat/RPMS/kernel-2.4.18-18.7.x.cern.i386.rpm
2) on the LCFG server execute this command:
/usr/local/bin/rpm4 --root /opt/local/linux/nginstallroot/7.3 --dbpath
/var/lib/rpm -Uvh kernel-2.4.18-18.7.x.cern.i386.rpm
As I have never tried this, there might be some dependencies or
incompatibilities, so try with --test first.
Please let me know if you manage to get the thing going.
Cheers
Emanuele
