This is a little something I ran into a while ago, and it occurred to me it might be of interest to anyone doing fencing or other power control operations.
Many servers have a BIOS option for what to do after a power failure. These are usually turn on, stay off, or 'auto', to return to whichever state it was in before. I set mine to auto, which led to a problematic situation! The server was not needed for a while so I did a normal power-off shutdown procedure, then turned off the server's PSU via a remote controlled PSU. Later I came to turn it back on and found I was stuck! Because it was in auto mode and had been shut down correctly, it was stuck turned off - turning on the PSU had no effect, so I had to call out an engineer to go and press the power button. The moral of the story is to leave the BIOS set to 'turn on' and then turn it off at the PSU; do not use the 'auto' mode! This particular server had no IPMI/ILO facility so I couldn't tell it to turn on that way.
