The Problem: The Server is restarting with no warning. It happened once a month.
We can see the Error in the imana :
Sensor: System Boot / Restart Initaiated (SysRestart) Event DDescription: System restart, cause unknown, command from ch #0 Event Code: 0x1d0700ff
After i checked logs we found that there's no problem from the hardware point of view. The restarts were requested from the OS.
I recommended to our partner a BIOS and iMana upgrade to the last version.
Final Solution : there was a OS issue, after the BIOS and iMANA update to the last version everything was ok.
After the upgrade, the server didn't experienced a system restart.
The current BIOS / iMana versions were:
BIOS Version: (U102)V396
Active iMana Version: (U1029)7.01
The server has been upgraded to BIOS / iMana version:
BIOS Version: V512
iMana Version: V719
