Updating the Universally Unique Identifier and DMI/SMBIOS data

After the system board is replaced, you must update the Universally Unique Identifier (UUID) and DMI/SMBIOS data in the integrated management module II (IMM2) on the new system board.

You can use the Advanced Settings Utility (ASU) and any of the following access methods:
  • Locally (in-band)
    • Through the Keyboard Controller Style (KCS) interface
    • Through the LAN over USB interface
  • Remotely over a LAN

You can use the ASU under any supported operating system, or you can use the Bootable Media Creator or a Windows- or Linux-based toolkit to create bootable media that contains the ASU. For information about the ASU and instructions for downloading and unpacking the ASU code, see the Advanced Settings Utility (ASU) for Lenovo x86 servers website and the Advanced Settings Utility User's Guide.

The following sections provide instructions for updating the UUID and DMI/SMBIOS data, using the different methods for accessing the IMM2. The following conventions apply to the command syntax:
  • Variables are shown in italics.
  • Optional parameters are enclosed in brackets ([ ]). Do not type the brackets in the commands. If you omit an optional parameter, the default is used.
  • Although the command syntax is shown in mixed case, the commands are not case sensitive.
  • Locally: Keyboard Controller Style (KCS)
    This access method uses the IPMI/KCS interface. The IPMI driver must be installed; with some operating systems, the IPMI driver is installed by default. The ASU provides the corresponding mapping layer.
  • Locally: LAN over USB
    If you omit any optional parameter, the default value is used. If one or more default values are used and the ASU cannot access the IMM by using the LAN over USB access method, the ASU automatically uses the KCS access method.
  • Remotely over a LAN
    If you omit any optional parameter, the default value is used.
