Re: [Linux-cluster] After APC switch was called with fence_node - server stays shut down - what can be modified?

I went through BIOS settings and could not find anything related to power loss. I did find the option where server is configured to dynamically operate in low power mode (but this is probably CPU related) and ASR (Auto System Recovery) was turned off.
So far nothing else jumped at me out of ordinary.

    Hello Alan,

    this looks like a bios configuration issue. Take look if you can find
    anything "power loss" related in bios and change it from "off" to "last
    state" or "on". I don't recall what it was called exaclty on the
    proliant bios or where you can find that option in bios setup...

    Hope this helps.

    Marc

    OT: You should also make usage of the iLO management devices in this
    boxes, they are rock solid fencing devices and react faster than the
    apc-power switches (we use DL360s and APC PDUs as fallback fencing
    here)...

The option should be called "Automatic Power-On" and should be in "Server Availability".

Marc
