I got more hints: Thanks to Dan: 1. use ZOC for a good break signal. -- Looks good, but does not 'break' the system either 2. maybe break has been switched off in NVRAM -- What to do if break or the console has been switched off in the nvram. Can I go back to the factory defaults?
Thanks to Kumud: 1. Did you try resetting NVRAM parameters by pressing ctrl+N ?? -- no di did not. When do I have to press ctrl-N? in LOM or at the disapeared console? To the system powered on or off? Thank you. Thanks to Robert: 1. typing "break" at the LOM> prom -- break seems not to be an allowed command at lom> 2. If you cannot get out of LOM, it is usually good to type "reset" at the LOM> prompt. That will reboot the machine, and then, once the machine is coming back up, when it is checking for the Operating System, you can then type "#." to get a LOM> prompt, and then type "break" to get the desired OK prompt. -- there is no indicator, that the machine is checking for the OS. Thanks to Mike: 1. remove the SCSI Disk, so that the system will ask for a booting device -- done, but I can not see a question about the booting device. An other question: What do I have to see, if the system boots correctly, but does not give me any console feedback? Are there any LEDs flashing at certain boot states or something else?
