HP DL380 G9 Can’t reboot until discharged cmos battery

[chunqiu033]

Hello,

I have two HP DL380 G9 servers. 

The first server has abnormal down When I was running mysql data synchronization in December 24, 2019 at 2 a.m.

The second server has abnormal down When I was running Mysql   in December 24, 2019 at 11 a.m.

The common phenomenon is that the power LED  flashing green (1 Hz/cycle per sec )  when I try reboot the two machine.  After trying a lot of methods contain  discharged operation by Motherboard but it does not work.

At last I discharged the CMOS battery and re-install it, however they started.

The serviceman thought it was a motherboard issue, but I don't agree with such a coincidence.

Within three years , the  HP DL380 G9 servers  with smart array p840  breakdown many times. Therefore, I think it is caused by the abnormality of the smart array p840.

What is the cause of the two servers breakdown ?

Thanks,

[chunqiu033]

Can anyone help me troubleshoot？

Hi Chunqiu033 ,

Have you received any hardware errors in IML ?

Normally  , if we clear NVRAM or Discharge CMOS   the system is prepared to erase all system configuration
settings from both CMOS and NVRAM .

Kindly refer the following HPE Knowledge Article ;

 This issue needs to be investigated deeper with the help of logs .

I would recommend you to  gather the AHS logs and OS logs from the server and log a case with HPE for further investigation .
