We have a warewulf cluster of about 20 nodes being standard PC boxes (I believe ATX, 4-year old) w/o hard drives - they boot from master machine via LAN. Some of the nodes tend to crash and we regularly have to go to the machine hall to press the restart buttons. We would like to avoid this. Is remote "hard" restarting nodes possible with standard ATX or we need some extra gadget for this functionality? The master machine doesn't crash - can we use its network card for sending the restart signal?
iAMT is probably the only implementation of something close to out-of-band you're likely to find on a standard consumer machine unfortunately. – Shinrai – 2010-12-03T19:10:06.040
