Hi we've just installed Ubuntu 12.04 LTS onto a new server. It's on a SuperMicro X9SCA-f Motherboard .

Now we're aiming to locate this in a remote server room - however when we execute a shutdown -r now the system completly shuts down and has to be restarted using the power button!! I cant find any BIOS setting that seems applicable.

Any help/pointers greatly appreciated.

Have you tried "reboot" ? –  Ed Villegas Jan 23 '13 at 14:29
    
Behaviour of shutdown is a setting in Ubuntu not in BIOS. –  Rinzwind Jan 23 '13 at 15:05
    
As a workaround tour could just use 'sudo reboot'. –  Seth Jan 23 '13 at 15:12
    
reboot does exactly the same :-( –  Julian Jan 23 '13 at 16:08
    
While this is not a duplicate but the opposite from why-cant-i-restart-shutdown the answers there might provide a clue for you too. –  guntbert Jan 28 '13 at 20:48

Restart using init:

sudo init 6

The init 6 command gracefully reboots the system running all the K* shutdown scripts first, before rebooting. The reboot command does a very quick reboot. It doesn’t execute any kill scripts, but just unmounts filesystems and restarts the system.

This is incorrect. reboot is only more abrupt than init 6 or shutdown -r now if you use reboot --force (or equivalently reboot -f). Normal operation of reboot (when run simply with sudo reboot) is to invoke shutdown, which in turn invokes init to change the runlevel. See man 8 reboot and man 8 shutdown for details. In other words, it is simply false to say that K* scripts are not run when rebooting with sudo reboot. They are. –  Eliah Kagan Apr 2 '13 at 17:31
