Introduction

This document describes how to upgrade ESXi for a Cisco Business Edition (BE6K/7K) via Cisco Integrated Management Controller (CIMC) vKVM interface.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- Cisco Business Edition Server Models

- ESXi vSphere

Components Used

The information in this document is based on these software and hardware versions:

- Business Edition Server BE6H-M5-K9

- ESXi 6.7 version

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

ESXi Upgrade

Pre-Upgrade Tasks

Validate the Correct ESXi Version to Upgrade

Determine the correct ESXi version to upgrade your BE server. You must validate the compatibility with two applications:

1. Compatibility with UC applications: To validate the supported versions of the UC application running on the server, refer to UC Applications Virtualization Guide.
For example, if you are hosting a CUCM14 virtual machine, the supported versions of VMware vSphere ESXi are 6.7, 7.0U1 and 8.0U1. In the virtualization table the minimum base version is listed, this means that CUCM14 compatibility is not supported for version 7.0, but it is supported for 7.0U1, 7.0U2, or 7.0U3.

2. Compatibility with CIMC:

Go to UCS Hardware and Software Compatibility Tool to validate the supported CIMC versions for your ESXi version:

- Server Type: Cisco Standalone Servers C-series

- Server model: refer to the table and select the correct UCS model according to your BE model.

- Processor Version: Select the latest

- Operating System: VMware

- Operating System Version: the ESXi destination version.

Compatibility tool example

If your current CIMC version is listed as compatible, there is no need to upgrade your CIMC. Otherwise, upgrade your CIMC with the Firmware Bundle link specified in the Details Column and refer to Install & Upgrade Guides in the Documents Column.

Validate the Virtual Drive the ESXi is Booting Up

Log in to your CIMC portal, navigate to Storage > Cisco Raid Controller > Virtual Drive Info and identify the Virtual Drive Name that has Boot Drive as true.

Download ISO File From VMware Portal

In order to get the correct ISO file for the upgrade, navigate to VMWare Portal > Select Version > Custom ISO > find Cisco Custom Image for ESXi > click on Go To Downloads.

Upgrade Tasks

Warning: You must power off your Virtual Machines gracefully. For UC appliances the correct process is to log in via SSH and type utils system shutdown command.

1. Set ESXi in maintenance mode. Navigate to ESXi GUI interface > right-click on Host > Maintenance Mode > Enter Maintenance Mode.

2. Open CIMC interface and click Launch vKVM from the toolbar.

Tip: The browser must allow pop-up windows as vKVM console opens in a different window.

3. In the vKVM console, click Virtual Media. If it is not enabled, click Activate Virtual Devices.

12. UCS starts loading the ESXi installer.

Caution: Make sure that your session stays active, if your browser connection is disconnected, the booting process from vDVD is going to fail.

Tip: Perform the upgrade from a local machine in the same UCS network to reduce the time it takes to load the ISO file.

14. End User License Agreement (EULA) appears, press F11 to Accept and Continue.

Tip: If the F11 key is not recognized you can use Macros Custom keys, navigate to Macros > Manage > New > Select F11 Key. The new key appears under Macro > User Defined Macros.

Post-Upgrade Tasks

Upgrade ESXi License

In case the ESXi upgrade is from a different major version (from 6.x to 7.x) you must upgrade your ESXi license too. There are different options to upgrade the ESXi license according to the type and the way it was purchased.

There are 3 types of ESXi licenses you can acquire with a BE6K/7K server:

1. VMware License

2. Cisco Re-sell License with ISV1 contract

3. Embedded License with SWSS contract

If the license was purchased directly with VMware, refer to VMWare License key requirements article or contact VMware.

If the license was purchased with Cisco, either Cisco re-sell with ISV1 or Embedded license, then upgrade your license through MCE tool, refer to MCE Version Upgrade Guide.
