We had a similar problem at a customer. The solution was to set these:
ilo_can_reset = 1
ilo_powerdown_method = reset
Despite the reset method, the machine was powered down.
Instead of being rebooted? Did you try a riloe management client
(I suppose that there is one)?
Yes, instead of being rebooted. The web iLO interface worked just fine, i.e.
a reset made it reboot immediately, a "4 second button press" made it
power down immediately, etc. But external/riloe stonith module triggered
a shutdown in every case. We were negatively impressed by this behaviour.
We also tried
ilo_powerdown_method = button
but this made the stonith resource to fail to start when one nodes was
powering up while the other stayed powered down.
Sorry, don't get this one. A stonith resource would fail to start
in case the monitor operation fails, e.g. when the stonith device
is not reachable. I don't see how that should be the case, unless
the whole box looses power. Disclaimer: No experience with riloe.
Yes, it was strange for us, too. The management interface was working,
the Windows browser client was working fine. But nevertheless, booting up
one node with heartbeat gave us a failed stonith resource.
One small detail is we started heartbeart manually and the node that
became alive
shot the other down when both were booted up but only one was running
heartbeat.
Actually it was just starting it and initializing stonith.
Our theory for the one powered up/one powered down case was that
external/riloe returned an error if it issued a "button" command to the
management interface and the node behind it was already off. The web
interface
may ignore it (because it's a NOP) but riloe was returning it as a failure.
