Additional information for the ssh or telent connection problem - When I telnet to S/390 machine there is a message issued from console before connection failed: modprobe: modprobe: Can't locate module char-major-5 The command 'chroot /mnt/target' is help to start /root/install script BUT We are not able to read since it's in hardware(3215) console mode. Also, it displays two messages at console: modprobe: modprobe: Can't locate module char-major-5 modprobe: modprobe: Can't locate module char-major-4 Thanks, Wayne Huang -------------------------------------------------------------------------------------- SDM Technical Support 1507 LBJ Freeway Park West M/S 16-2196, Dallas, TX 75234 Email: whuang@us.ibm.com
