SMBIOS chassis information is not filled in correctly - Lenovo Flex System x240 M5 Compute Node (9532)

Resolving The Problem

Source

RETAIN tip: H214215

Symptom

The Chassis Universally Unique Identifier (UUID) is in System Management Basic Input/Output System (SMBIOS) at type 3 offset 7 --> Serial Number.

Affected configurations

The system can be any of the following Lenovo servers:

• Flex System x240 M5 Compute Node, type 9532, any model

This tip is not option specific.

Solution

This behavior will be corrected in a future release of Unified Extensible Firmware Interface (UEFI).

The target date for this release is fourth quarter 2015.

The file will be 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

Find this UUID directly from the CMM console.

1. SSH to the Chassis Management Module (CMM) console.
2. Login with the account and password.
3. Type in info.
4. The first UUID represents the chassis UUID.

(where SSH = Secure Shell)

Additional information

Currently, the chassis UUID is stored in the CMM. When the Integrated Management Module (IMM) boots up, the IMM retrieves this value from the CMM and store it at a specific location within itself. UEFI gets this value from the IMM later, when users power up the system. In this case, UEFI cannot get the exact value from the IMM, and defaults the value to zeros.
