What is the problem?
You need to create a static /dev/console node. I think it's a
character device, major 5 minor 1. Also, your DASD spec will have
changed. Instead of dasd=150-155 or whatever, it'd be
dasd=0.0.150-0.0.155. Don't forget to rerun zipl.
Further, there are some changes to the chandev layer to get your
network devices working again with the new group devices stuff.
I did that with the creation of a file /etc/groupdev, and the following
script (/etc/init.d/groupdev.sh):
#
# groupdev.sh S/390 module initialization parameters
#
# Must run before networking but after udev.
#
# Version: @(#)groupdev.sh 0.0-0 27-Apr-2004

#
[ -f /etc/default/rcS ] && . /etc/default/rcS
test -f /etc/groupdev && (
# Loop over lines in /etc/groupdev
echo -n "Initializing ccwgroup devices..."
while read type rest
do
case "$type" in ""|\#*)
continue
;;
esac
case "$type" in "qeth")
modprobe -k ${type}
set -- $rest
echo "0.0.${1},0.0.${2},0.0.${3}" >
/sys/bus/ccwgroup/drivers/${type
}/group
echo $4 > /sys/bus/ccwgroup/drivers/${type}/0.0.${1}/online
;;
esac
done
echo "done."
) < /etc/groupdev
: exit 0
And /etc/groupdev contains:
# format is:
# type rest
# type is "qeth" or another grouped device
# qeth is the only one I know about right now.
#
# for qeth, rest is
# read-device write-device data-device online
# where the devices are four-digit hex addresses,
# and online is "1" or "0" for whether the device should be
# on- or offline
qeth 0340 0341 0342 1
qeth 0344 0345 0346 1
Hope this helps.
