Hi! Thanks for your answer! But how shall I do this? After an update the machine automaticly reboots... Should I reboot from the CD somehow? I figure, after the reboot I should press "TAB" and then write "manual", let yast start, load the SCSI-drives and cancel using "Ctrl-C", is the command-line there after that and the commands you suggest could be executed? (Can't access the server for the moment, so I can't try this just yet). Very greatful for clearification. Thanks!

But after an reboot there was an Kernel panic : Unable to mount root. (Apparently the SCSI-drives were not loaded in the new kernel...) The SCSI drivers are not compiled into the kernel but have to be loaded from the initial ramdisk aka initrd. First check that INITRD_MODULES in /etc/rc.config lists the needed SCSI driver. If not, add it. Then run mk_initrd which will create the initrd and then call lilo which has to record the position of the initrd on the disk. Next time you boot all should go well.
