ILO Log - Server power removed.

[Ong Kean Lee]

I have 2 nodes cluster server running on ProLiant DL385 G2. 1 of the node is experiencing unexpected reboot almost every day. It's running on Windows Server 2003 and nothing can be found from event logs.

Upon checking on the ILO log, i found a description "Server power removed" and the date/time is the same when the server was shutdown.

I can't find any hardware error from System Management. Currently the power supply is not running in redundant mode.

Any advice?

check components in the power connection:
- power outlet
- power cord
- Power supply
Do this one step at a time.

- power outlet may be tested by connecting a digital clock that resets to 00:00 when power is lost.
maybe some wire is not properly connected.
- powercords are not hard to get by.
maybe the connector doesn't fit right. try another one.
- maybe you can replace the PSU with the other node in the cluster?
See if the problem moves too.
but if this was the problem, i would expect this logged in the ILO log.


.....
be sure the cleaner service doesn't use the power outlet for the vacuum cleaner :-(

This may or may not be relevant.

Is the power cord supplied by HP?

In one instance, I have noticed that some "other" power cords fit loosely in the PS socket and did cause intermittent reboots.

Are you certain that house power is constant - like Pieter said, plug something in to the outlet that will "reset" if the power goes out.

I'll try to check on the power cord and see how it goes. Will replace it and try...
