DL360 G6 - random reboots

[Fabio Pajalunga]

Hi Community

We're running a SBS 2008 on a HP DL360 G6 and we got the following issues:

After upgrading our Exchange 2007 (on a SBS2008 SP2) to SP3, we had several unexpected reboots. There are almost no logs written (only log created is a EventID 6008) and there is no regularity, reboots on full load or without any load, "he" don't care at all (1-3 times a week).

System is kept up to date, mainly used for Mail (ofc. DNS/DHCP/AD).

If you need more specific informations, just ask... we run out of ideas to solve this problem...

Hi Fabio,

Did you disable the windows ASR and ASR from System System Bios.

Enable the mini memory dump after disabling the ASR and observe if mini dump are generated or any specific error that is observed on post or in event logs.

this behaviour is observed after exchange 2007 upgrade... is there any installation/upgrade logs that you can access.

Is windows updated with the latest service pack or updates before upgrading the system ?

thanks,
Aftab

Windows was up to date before updating the Exchange Service.

Don't know if ASR is disabled (probably not, no minidumps generated), because I began supporting this server a few weeks ago and there is no installation documentation...

Hi Fabio,

ASR increases server availability by restarting the server within a specified time after a system hang or shutdown. At the same time, the HP SIM console notifies you by sending a message to a designated pager number that ASR has restarted the system. You can disable ASR from the HP SIM console or through RBSU. Press F9 during Post to access RBSU >> disable Automatic Server recovery (ASR)

you can enable memory dump and disable windows ASR
right click my computer >> properties >> Advanced >> Startup and recovery >> settings >> uncheck automatically restart and select Small memory Dump.

Also make sure you have latest Proliant support pack installed

Now we can monitor the server for sometime to see whether it generates any error message/ events or memory dump.

thanks,
Aftab

Hi,

Thanks for your fast reply Aftab :)

Done the minidump setting and waiting for next reboot - will post the minidump here when I get it :)

Ok, Server has rebooted once in the past 72 hours - but there is no Minidump generated in the Systemroot folder ...

and the biggest problem, I can't disable the autoreboot function...

How can I solve this problem anyways?

Hi Fabio,

Similar Event ID :6008 issue was observed in windows SBS 2003 and there was a hotfix from microsoft to fix this.
ref.. : http://support.microsoft.com/kb/950323

http://www.eventid.net/display.asp?eventid=6008&eventno=14&source=EventLog&phase=1

this happend after exchange upgrade so could be known issue with microsoft.. if you have contract on Microsoft please contact them.

Please take a look at the steps mentioned in these articles to generate minidump to be further analyzed by microsoft.

generating memory dump:

Also SBS can not be used as a standalone server (like file server, webserver etc.).. it has to be primary domain controller.

hope this helps,

thanks

Ok, there was a reboot this afternoon - got an exact time, no warnings / crit logs at all as already mentioned.

redundant power supply and in front of DL360, HP USP R1500. No Logs at all on the USP either ... maybe power supply problem?

You could set the automatic reboot to show the error.

System
Advanced
Startup and Recovery
Settings
Uncheck automatic restart
