Proliant ML370 G3 unexected restarts

I'm running 2 Proliant ML370 G3 servers. The problem is the following - every once in a while one of the servers unexpectedly restarts without posting anything in the Event log, except for "Unexpected restart".

What has been done to solve this problem - changed motherboard (didn't help), power supply (didn't help), RAM (didn't help)

Did anybody had this problem and how it has been solved?

Check the system management log; there might be some useful info.

Could it be that there are power problems ? Are the systems connected to a UPS ?

Re: Proliant ML370 G3 unexected restarts

I think, I've found the problem:
There was a "blue screen" event in the management log, I suspect that because of perflib generating huge amount of errors, there was a buffer overflow (was described here somewhere, which lead to restart).

I've disabled the counters, and so far it seemes to be allright, but no guarantees.

Are you getting a STOP 0x44 bugcheck in the IML? If so, check the version of

HP ProLiant Advanced System Management Controller Driver for Windows 2000 (http://h18023.www1.hp.com/support/files/server/us/download/17743.html)

or

HP ProLiant iLO Advanced System Management Controller Driver for Windows 2000 (http://h18023.www1.hp.com/support/files/server/us/download/17742.html)

Re: Proliant ML370 G3 unexected restarts

Hi,
How much power supplies do you have in your servers?
I'm asking, because we had the same problem. We have more or less the same config but we had only 1 power supply! We needed to add a 2 power supply, after that we had no unexpected reboots.

Re: Proliant ML370 G3 unexected restarts

To be more precise, here is some more info:

We had our dual-cpu ml370 g3 doing unexpected reboots. No error logging was shown in the compaq web agents. The only thing that was logged was in the win2k event viewer, unexpected shutdown or reboot... I can't remember the exact message.

We had only one power supply, for 6 hd, 2cpu, 1 ait, etc. We changed the cpu's, the ram etc.. nothing changed, still reboots and still no error messages in compaq web agents. The key was to add a second power supply. After that, we started to get "power supply not redundant anymore" messages in the compaq agents. The 1st power supply was actually buggy!

Now we have changed the buggy power supplied and kept the second power supply as we were still suspicious that one supply was definitely not enough. Have a second supply is even better because of the redundancy.
Since that day we didn't have any reboots.
