Hi,

How do we find if the system got hang?

I you type Ctrl-Alt-F1 and are able to log in, the system isn't hung. The GUI may not be responsive due to a process being hung though. If that is the case, there are ways to find out what the process is and stop it.

The acid-test I use is to press caps lock/num lock and see if the LED indicator toggles on/off. If not, I find the system is usually totally stuck - or at least in a state where I can't do very much good without cycling the power.

There is a special key combo which will reboot your system if the kernel is getting keyboard events, and is sometimes useful if you can't easily get to a power switch:

Hold down alt and sysrq (print screen), then, While holding them type REISUB. On the 'B' key the system should reboot. It's not a pretty way to do it though, and I don't know if there is really any advantage over cycling th power. Still, it's kinda fun.

I'm managing the box using ILO(console) which provided by HP. How do I check remotly? Thank in advance.

Maybe ILO has some system monitor built-in. You should refer to the ILO documentation or talk to your HP customer service droid to find out.

Failing that, how about ping?

this is an excellent question. i've always wondered what constitutes a crash. i personally define it as when the computers gone into an infinite loop. what about all of you?
