Issue Description

After restarting the iBMC of an Rh1288 V3 server, Esight displays the error  ACPI Status S0

Alarm Information

Esight displays the error  ACPI Status S0 , but in the iBMC there is no error:

 

 

Handling Process

Check the iBMC and there is no error message

 

 

Root Cause

However, by connecting to the server iBMC no alert appears. The ACPI is not an error , need to check the BIOS settings.

 

Advanced Configuration and Power Interface (ACPI) enables the operating system to set up and control the individual hardware components. ACPI supersedes both Power Management Plug and Play (PnP) and Advanced Power Management (APM). It delivers information about the battery, AC adapter, temperature, fan and system events, like "close lid" or "battery low".

 

Solution

The ACPI is not an hardware error, It means that there is no faulty part , the ACPI is Advanced Configuration and Power Interface ,the S0 state of ACPI it means that the server is fully functional.

The ACPI function implements power management for processor, battery and embedded controller through the operating system (OS). It can ensure the server performance while reducing the power consumption. Available ACPI specifications are as follows: ACPI1.0B  /   ACPI3.0  /  ACPI4.0

In a computer, the Advanced Configuration and Power Interface (ACPI) provides an open standard that operating systems can use to discover and configure computer hardwarecomponents, to perform power management by (for example) putting unused components to sleep, and to perform status monitoring.

ACPI 10.B it means  Advanced Configuration and Power Interface Specification, Revision 1.0b , and describes the structures and mechanisms necessary to design operating system-directed power management and make advanced configuratioin architectures possible. ACPI applies to all classes of computers. If you want to design and build an ACPI-compatible system, you need the ACPI Specification.

Version 1.0b of the specification includes:

 

A full revision history, provided as text in the begining of the document, replacing the the change bars
 

  • The content of the Advanced Configuration and Power Interface Specification, Revision 1.0a
     
  • The Errata to the Advanced Configuration and Power Interface Specification 
     
  • The Video Extensions
  •  
  • ACPI3.0: The Advanced Configuration and Power Interface Specification, Revision 3.0 describes the structures and mechanisms necessary to design operating system-directed power management and make advanced configuration architectures possible. ACPI applies to all classes of computers. If you want to design and build an ACPI-compatible system, you need the ACPI Specification.  
  • ACPI4.0: The Advanced Configuration and Power Interface Specification, Revision 4.0 describes the structures and mechanisms necessary to design operating system-directed power management and make advanced configuration architectures possible. ACPI applies to all classes of computers. If you want to design and build an ACPI-compatible system, you need the ACPI Specification. ACPI 4.0 defines additional fan device interface objects enabling OSPM to perform more robust active cooling thermal control. Revision 4.0 of the ACPI specification added various new features to the design; most notable are the USB 3.0 support, logical processor idling support, and x2APIC support.

        

          Suggestions

          Nee to check in the BIOS – Advanced - what value is set to ACPI , it must to be set to ACPI3.0 and to Modern Mode.
