1.Symptom

UEFI0315: Unable to process an iDRAC request to configure Secure Boot keys because of a communication error between BIOS and iDRAC…

Example of Lifecycle Controller Logs:

UEFI0315

Unable to process an iDRAC request to configure Secure Boot keys because of a communication error between BIOS and iDRAC.

 

This error banner is displayed when BIOS fails to receive an expected Secure Boot setting value during the Power-On Self-Test (POST) sequence. When iDRAC8 is downgraded from 2.70.70.70, this reading fails regardless of Secure Boot settings within server BIOS.


The Lifecycle Controller Logs of the iDRAC8 will record if the iDRAC8 firmware has changed. Searching for the event "PR36" will show the history of firmware updates that are applied to the server.

 

PR36

Version change detected for Lifecycle Controller firmware. Previous version:2.70.70.70, Current version:2.61.60.60

 

 



2.Solution

iDRAC8 firmware 2.70.70.70 resolved an issue that was leading to this sighting randomly. Downgrading from the iDRAC8 2.70.70.70 is persistently causing the error to return. If the iDRAC8 firmware is confirmed to have been downgraded, this error is not an indication of faulty hardware.

Use one of the following methods to clear the condition from impacted servers.
 

  • Option 1: Update iDRAC8 to 2.70.70.70

Reinstalling iDRAC8 to firmware version 2.70.70.70 will restore the fix that corrects this condition. The server will need to be warm rebooted after the iDRAC firmware update completes.

  • Option 2: Reset Secure Boot Keys via Redfish API

If the server needs to remain on downgraded iDRAC8 firmware, the Secure Boot Keys of the system BIOS need to be reset. Redfish API is the only method to modify this setting. Follow the instructions below to modify the /redfish/v1/Systems/System.Embedded.1/SecureBoot/Actions/SecureBoot.ResetKeys value.
 

SLN320150_en_US__2icon Warning: Resetting Secure Boot Keys is destructive for any configurations that are using the Secure Boot feature. Back up keys through the BIOS menu before proceeding.

 
Secure Boot Policy setting needs to be set to Custom attempting to reset Secure Boot Keys. Secure Boot can either be Enable or Disabled. 


F2 System Setup >> System BIOS >> System Security >> Secure Boot:

SLN320150_en_US__3BIOS-SecureBoot-Settings-v3

SLN320150_en_US__4icon Note: Secure Boot is Disabled by default. In Legacy BIOS Boot Mode, the Secure Boot setting is not configurable.  

 

SLN320150_en_US__4icon Note: Lifecycle Controller will need to collect system inventory on restart after making any changes to the Secure Boot settings in BIOS. Boot server into Operating System before sending Redfish Post command.

  • Select POST from the action dropdown menu.
  • Enter URL Bar: https://iDRAC_IP/redfish/v1/Systems/System.Embedded.1/SecureBoot/Actions/SecureBoot.ResetKeys
