Purpose

This article provides instructions for updating the Cisco UCS C240 M5 servers in a VMware Cloud Foundation environment to allow for correct boot configuration

Cause

By default, the UEFI BIOS mode on Cisco UCS C240 M5 servers only allows the NICs to be configured in the UEFI mode and the M2 drives to be configured only in Legacy BIOS mode.

Resolution

To resolve this issue, use the following instructions to enable the x710 NICs for PXE in legacy bios mode:

Download the PREBOOT.EXE file from Intel's web site.

Run the downloaded PREBOOT.EXE file on a Windows system. A folder named Intel23.1 will be created on the C:\ drive.

Copy the C:\Intel23.1\APPS\BootUtil folder to the Desktop of the Windows system.

Access the Cisco UCS KVM Console from the same Windows system.

Navigate to the Virtual Media, Create Image, Create Image from folder menu.

Click the Browse button next to Source Folder and select the C:\users\<username>\Desktop\BootUtil folder.

Note: The New Image File name will be automatically populated and does not need to be changed. It should be C:\users\<username>\Desktop\BootUtil.img.

Click the Create Image button.

Navigate to the Virtual Media, Map Removable Disk, Create Image from folder menu.

Click the Browse button next to Drive/Image File and choose the C:\users\<username>\Desktop\BootUtil.img file.

Click the Map Device button

Boot the server into the UEFI shell.

Issue the following commands:

map -r
fs01:
dir

Note: You should see the BootUtil folder in the output of the previous command. If it is not present, re-run the fs01: command but replace 01 with a different number (04 for example) and re-run the dir command to verify that the BootUtil folder is present.

cd BootUtil
EFIx64\BOOTUTIL64E.EFI

Note: You will see output similar to the following:

Port Network Address Location Series WOL Flash Firmware                Version
==== =============== ======== ====== === ============================= =======
1   B4DE31906E4A   1.00.0   10GbE  N/A UEFI,CLP,PXE Enabled,iSCSI    2.3.72
2   B4DE31906E4b   1.00.1   10GbE  N/A UEFI,CLP,PXE Enabled,iSCSI    2.3.72
3   3CFDFEB0EF80   25.00.0  40GbE  N/A UEFI,CLP,PXE,iSCSI            -------
4   3CFDFEB0EF80   25.00.1  40GbE  N/A UEFI,CLP,PXE,iSCSI            -------

EFIx64\BOOTUTIL64E.EFI  -NIC=<port number> -BOOTENABLE=PXE

Notes:

Replace <port number> with the port number corresponding to the NIC needed for PXE booting the server. To help with identifying the proper port, the Lights Out Management (LOM) ports are 10GbE and the Intel x710 ports are 40 GbE.

Once the port is enabled you will see the firmware version for that port when running the EFIx64\BOOTUTIL64E.EFI command.

The previous command will need to be run for both available ports.

At this point, PXE is enabled on the Intel x710 NIC card in the legacy bios mode.
