ML370 G3 Spontaneous Reboots

[Pete Simpson_1]

I have several (three) ML370 G3 units that spontaneously reboot for no reason whatsoeever. ASR does the reboot. If we shut off ASR, there is no blue screen. The box just hangs. Never an event in the event log.

One one box we've even gone so far as to replace EVERY SINGLE COMPONENT in tbe box except for the actual OUTER CASE of the system.

Anyone have ANY idea why this happens? It's only on ML370 G3's and it looks like I'm not the only one in this boat...

Pete:

Have you installed the latest bios on the servers? There has been some microcode fixes to the processors that may solve this:

Let me know what you find? -john

Well, when one of the systems rebooted this morning I did apply the firmware updates on the latest SmartStart Firmware CD v7.10. Not sure if that's the same revision as the firmware link you sent. I'll check that to see if they are the same.

Did you find a technote or something indicating the fixes in that BIOS / Microcode / Firmware? Did it say anything about auto-magic reboots?

Pete:

Well... if you take a look at the Revision History of the bios updates, there a lot of fixes related to many system hangs:

Are you running the health drivers from the PSP? You must have the drivers and agents running to reset the ASR timer from within the O/S.

Are these up to date?

We've been suffering from the same problem on 2 of our 4 ML370 G3 that we purchased last August.
The problem has been resolved after HP Tech replaced back plane of the server.
Check with HP support to replace back plane of your server.

The heavy workload on that box was transitioned elsewhere. Seems to be workload related. Now that box is basically idle it no longer happens.

I agree it may be the backplane. When we put a load back on the machine if the problem returns we'll request that be replaced first.

The information I got so far on this problem is as follow:

This problem occurs on ML350/370 G3:

- manufactured prior to Apr./2004.
- with following CPU types:
3.06GHz/512KB
3.2GHz/512KB
3.2GHz/1MB
- with 2 power supplies
- when running full CPU

You wouldn't happen to have a spare part number for this.

Thanx

Hi,

I had this problem on the same server but with a SMART ARRAY 6400. We had change the motherboard but with no success, the server continue to reboot with ASR. Finally we change the scsi card smart array 6400 and since three weeks the server doesn't reboot. i hope this can help us .

The problem turned out to be the PCI riser card. They either came loose in shipping, despite being screwed down, or were slightly out of alignment when the servers were rack mounted.

Removing and deliberately reinstalling them very firmly and directly into the slot resolved all spontaneous reboot problems.
