SMBIOS type 10 and 41 contents always show 'enabled' for Ethernet devices, even when they are disabled - IBM BladeCenter and System x

Troubleshooting


Problem

After Ethernet devices are disabled in the Unified Extensible Firmware Interface (UEFI) F1 Setup menu, the devices are still displayed in System Management BIOS (SMBIOS) type 10 and 41. This issue occurs when using the Desktop Management Interface (DMI)utility to dump SMBIOS type 10 and 41. The response is similar to these messages: Handle 0x0058, DMI type 41, 11 bytes on-board Device Reference Designation: Ethernet 1 BroadCom 5709C Ethernet Controller Type: Ethernet Status: Enabled Type Instance: 1 Bus Address: 0000:0b:00.0 The status always shows 'Enabled', even if this device was disabled in the UEFI F1 Setup menu.

Symptom

After Ethernet devices are disabled in the Unified Extensible Firmware Interface (UEFI) F1 Setup menu, the devices are still displayed in System Management BIOS (SMBIOS) type 10 and 41.

This issue occurs when using the Desktop Management Interface (DMI) utility to dump SMBIOS type 10 and 41. The response is similar to these messages:

  Handle 0x0058, DMI type 41, 11 bytes
on-board Device
Reference Designation: Ethernet 1 BroadCom 5709C Ethernet Controller
Type: Ethernet
Status: Enabled
Type Instance: 1
Bus Address: 0000:0b:00.0

The status always shows 'Enabled', even if this device was disabled in the UEFI F1 Setup menu.

Affected configurations

The system can be any of the following IBM servers:

This tip is not software specific.

The following system BIOS or UEFI levels are affected:

The system has the symptom described above.

Solution

This behavior has been corrected in Unified Extensible Firmware Interface (UEFI) firmware update released with Second Quarter 2014 system code stack.

The file is available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and operating system on IBM Support's Fix Central web page, at the following URL:

Workaround

Instead of SMBIOS, use either the lspci command on Linux, or use the Microsoft Windows Device Manager to check available Peripheral Component Interconnect (PCI) devices.
