Situation: I remote into the IP-KVM, see a kernel crash error or some other "frozen" situation on the server. Ctrl-Alt-Del does nothing. How do I reboot it?
coupled with an ip kvm it should, provided its fast enough you could at least watch the boot process to see whats happening, and where it's hanging. obviously in the case of hardware failure it's not going to do much but if it's just hanging wating for user input for whatever reason, it'll be a go.
I am wishing I had this too. A server I run today decided that after a few weeks of behaving, it wanted to play dead again.
Next time I will bite the bullet and just buy a Sun rackmount. They sell AMD-based 1us with a full service processor for about "500. Right now I wish to christ I had one.
Was going to mention an ILO card, looks like you found it.
They will work on any HP server perfectly but they can also work on other servers, you will just have to do a bit of research. Basically there is a little cable running from the ILO card to the MB that simulates a power button press. So if your unit has hung you can simulate a 5 second power press to force reboot. So you will need to check if your MB has a header to support this. However all other functionality should work even if you can't connect the cable(so no power option)and you can even remotely mount floppies and cdroms from your pc at home.
