Issue Description

RH2288H V5 server in OS there is error message "BIOS needs update for cpu frequency support"

 


Alarm Information

BIOS needs update for cpu frequency support in OS, but there is no alarm in hardware log.

Handling Process

1, check the compatibility list in below link:

 

http://support.huawei.com/onlinetoolsweb/ftca/indexEn?serise=2

 

confirmed the OS is in the compatibility list.

 

2,check the BIOS setting for the EIST support and Power policy select. and found the power policy select is "performance" , EIST Support is "enabled", not the same as below

 

 

 

Root Cause

If the power policy select is "performance" , EIST Support is "enabled", CPU cant change the frequency by itself, and if the EIST is enabled,  the BIOS can't report the PSS Table information to OS, then OS will have this kind of alarm.

 

if it is customer requirement to set the Power policy as "performance", we can ignore the message.otherwise, we can change the power policy to be "customize"

Solution

if it is customer requirement to set the Power policy as "performance", we can ignore the message.otherwise, we can change the power policy to be "customize"
