I tried to watch the output from the Integrated ASCII console and the Operating system messages from IBM Hardware Management Console. But there is nothing interesting there From Operating System Messages, it ends at: [ OK ] Reached target Final Step. [ OK ] Started Reboot. [ OK ] Reached target Reboot. And never proceed from this point. And HMC shows "Not operating" From Integrated ASCII console it just shows the login prompt, never prints any other message.
