Proliant 8000 Rebooting on it's own

We have a proliant 8000 running Windows 2003 Server. When we received this server it only had one hot/swap power supply. We purchasd several new ones to make the power supplies redundant. Now with all three power supplies installed and plugged in, the server reboots about once a day unexpectedly. If we unplug two of the three it will stay up. We have tried several different power supplies to make sure we didn't get a bad one but have had no success. This server is part of a SQL cluster and needs to be available 24/7.

The other strange thing here is there are no events being logged when the server reboots.

Any help here would be greatly appreciated .

Thanks

Hi,

Anything under IML

Check IML again if it reboot after ASR Disable.

Anything under event log.

We have turned ASR off awhile ago, still nothing in IML. Nothing in event logs either. This has me very confused as usually you will see some kind of event logged when hardware has issues.

Hi,

A Compaq ProLiant 8000 or ProLiant 8500 Server configured with a power supply having a label with a date code within the Serial Number of x9938xxxxxxx (or lower) may require replacement of the power supply.When an affected power supply fails,
Check the serial no on psu

Hi,

Check it by swapping the PSU with other to validate the PSU issu or not

Well, It didn't take long. It is back to rebooting itself. Any other suggestions?

Re: Proliant 8000 Rebooting on it's own

So, what is conclusion that one of the ps is failing or it is restarting due to some other reason.
Tried to run daignotic on it in loops then keep it under observation
as asr is disabled anything under IML.

Still nothing in IML or event viewer. Disconnected two of the three power supplies, now the system will stay up. Do all three power supplies need to have the same revision number?

Any other suggestions?

Thanks for all your help:)
