I have a HP ProLiant DL160 G5 and a real strange problem:

If the server is unplugged for several minutes, it comes up without any problems.

If I gracefully shut it down, pressing the power button doesn't power it up again. Replugging the power cable also doesn't help. The only solution is to unplug it for several minutes, wait, and replug it. Together with some magic unicorn dust eventually it comes up again.

I'm able to connect to the serial IPMI console. So I tried to trigger a boot from there and typed:

/./-> cd system1
/./system1/-> start
System1 started.

But guess what, it doesn't come up, just nothing happens.

Did anyone already have similar behaviours?

Sounds like a broken capacitor to me. If you're lucky, it's in the power supply. Try changing it and compare the result. If it persists, another, more important piece might be damaged.

Less likely, but easier to fix could be an issue in the BIOS. Try reflashing it (with the most recent version). Also, try starting the server with just one stick of RAM to rule out any issues there.
