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)...
