Hi,
After issuing shutdown -F or shutdown -F now my server is getting restarted.
Any Idea?
What did you want it to do ? To halt , I would use shutdown -Fh.
Hmm, check the SMS boot options, I think you can set the shutdown and restart policy in SMS and it probably has a restart option set.
What type of system is it? Most have the SMS options listed on the IBM website.
"lsconf | head" or "prtconf | head" should probably show the system.
init 5
or
shutdown -i 5 -g0 -y
